Abstract
A device for automatically dispensing coupons or the like. The problem with conventional coupon distribution is that consumers do not really redeem the coupons. The device employs a point-of-purchase promotion and distribution of the coupons. The device is self-powered (109, 110) and a compact intelligent device (101) which has an element (105) which senses the proximity of a consumer and draws their attention by emitting an audio-visual signal (106) while simultaneously presenting the promotional material (108) through a slot (104).
Description
POINT-OF-PURCHASE COUPON DISPENSER
The invention relates to a machine for automatically dispensing coupons or the like. More particularly, the invention concerns an automatic coupon dispensing machine with means for sensing proximity of a consumer and means for attracting the attention of the consumer.
In recent years, the number and value of grocery coupons distributed has steadily increased yet consumer redemption has steadily decreased.
Consumer behaviour and the understanding of it has led to the need for Point-of-Sales marketing. In 1988 the Point-of-Purchasing Advertising Institute surveyed 50,000 consumers in the act of buying and found that:
90% had not looked at promotional circulars 86% had not heard broadcast messages 80% were not redeeming coupons 75 % had not checked store ads Moreover, media used for advertising includes prime time network television. Over the last decade, however, the networks' share of the audience has dropped from 92% to 67% according to A.C. Nielson Co.
and the daytime audience has fallen from 78% down to 57%. Yet the cost of 30 seconds of prime time network air time has increased 85 % .
See, Stalking the New Consumer, Business Week, August 28, 1989.
A study was conducted in 1988 to review the redemption rates of grocery coupons for the year 1987 compared with 1988. See, Progressive Grocer, October 1988. The results of this study are as follows:
6 ~ 7 Source of Coupons% Redemption % Change Daily Newspaper 4.0% -25%
Sunday Newspaper 4.8 % -27 %
M~g~7ines 5.4 % -19 %
Direct Mail 5.8% -28%
Instant On-Pack 31.0% + 11 %
It can be seen that the instant on-pack coupon (instant redemption coupon attached to a product and redeemed at the check out counter) shows an impressive 31% redemption rate and is the only coupon distribution vehicle that has shown an increase in redemption since 1984. Id.
Consumer research also shows that: "Two thirds of all buying decisions are made in the store." Thus, advertisers should concentrate their efforts on in-store promotion.
Under these conditions, it is appal~nt that a point-of-sales marketing program holds the greatest redemption percentage of any other coupon distribution method in use today. A clear indication of this is the 300-600% increase in product movement typically experienced on the day of an in-store product demonstration.
Manufacturers and retailers are thus challenged to offer an innovative point-of-sales promotional method that satisfies the stringent convenience requirements of consumers while generating greater sustained levels of product awareness. The Automatic Coupon Machine of the present invention provides the consumer with convenience, value, and time savings.

SUMMARY OF TH~ I~v~lIO~
Accordingly, it is an object of the invention to provide an improved method for distributing manufacturers' or retailers' promotional material directly to the consumer at the time the decision to purchase is being made by the consumer.
Another object of the invention is to provide a dis-pensing device in a small, self contained enclosure which can be located in the vicinity of a relevant product display without detracting from the product display.
A further object of the invention is to attract the attention of consumers as they approach or pass a product dis-play and to visibly dispense promotional material such as a coupon.
The above and other objects are achieved by the inven-tive Automatic Coupon Machine (ACM), for automatic dispensing of promotional material. ~he preferred embodiment of the ACM is designed to be mounted on the front portion of a retail shelf directly in front of the product specified on the promotional material to be dispensed. The ACM automatically detects the proximity of a consumer with the use of a sensor. Upon detect-ing the presence of a consumer, the ACM activates audio/visual 207 31;87 r ~

DET~TTT~'D DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to Fig. 1, a preferred embodiment of the Automatic Coupon M~Ch ine (ACM) 101 is shown mounted on a retail store shelf 102 with the use of brackets 103. The overall dimensions of the ACM 101 are preferably such that it may be so mounted on display shelf 102 without eclipsing products displayed on the shelf. Nevertheless, the ACM can be configured several different ways as will become apparent in the following description.
The preferred embodiment of the ACM 101 is provided with a coupon dispensing slot 104, a sensor 105 to sense the W~YI/1~77 PCT/US91/~ ~1 6 20~36~7 proXImity of a consumer, and audio/visual means 106 to attract the attention of a consumer to the ACM. In the embodiment shown in Fig. 1, audio/visual means 106 is simply a buzzer or other sounding device and sensing means 105 is an ultrasonic trans-ducer. However, other audio/visual means and sensing means may be employed, for example a visual display of some type and an infrared sensor.
It is also preferable that the ACM contain s~me means 107 for sensing the presence of a coupon 108 in the coupon dispensing slot 104.
The embodiment shown in Fig. 1 is also provided with a solar cell 109 for charging batteries 110 tFig. 2), although other sources of power may be used.
Access to the ACM is preferably obtained by way of some lock and key means 111, 112 as shown by example in Fig. 1.
The embodiment shown in Fig. 1 is also optionally provided with automatic shut off means 113, in the form of a photo transistor which senses when ambient lighting is turned on and off.
Fig. 2 shows the internal components of the exemplary ACM of Fig. 1. All the internal components are contained within housing 115 which is provided with mounting means 103 as dis-cussed briefly above and in further detail with reference to Fig. 8. Housing 115 can be made of ABS plastic or any other suitable material.
Power source 110 is preferably nickel cadmium batteries which can be charged by solar cell 109, but other types of batteries may be used without charging, or a transformer may be used to secure power for the ACM from an AC line.
Sensing means 105 is preferably an ultra-sonic trans-ducer such as a Polaroid series 7000 (Needham Heights, Massachusetts) although an infrared sensing means could also be used.
W~ Yl/ 1~ / / PCT/US91/~ ~1 ~ Coupon sensing means 107 is preferably an optical sensor such as an Omron (now, Sen-I-Sys, Plano, Texas) part number EE-SX-1023-Wl which detects the presence of an exposed coupon 108 in coupon slot 104.
Audio/visual means 106 may be a piezo-electric buzzer such as that manufactured by Monaco Components, Inc. (Glen Head, New York) part #SEP-1112 or a speaker such as Panasonic (Secaucus, New Jersey) part number 3P108S, to produce either a beeping sound or a short recorded message to attract the atten-tion of consumers as they come within proximity of the ACM.
Other audio/visual means such as LEDs, LCDs, electroluminescent panels, video displays or the like can also be used within the scope of this invention.
Access to the ACM may be through a hinge 116 provided at the rear of the housing 115 whereby the rear panel of the housing is opened when lock 111 is activated with key 112.
Other access means could be easily provided and this is shown only as one example.
A preferred embodiment of the ACM also includes a photo-transistor 113 to detect the intensity o~ ambient light.
When the location of the ACM becomes dark, such as when a retail establishment closes for the evening, the photo-transistor 113 will automatically shut off the ACM to conserve power and extend battery life.
Fig. 2 also shows a coupon tray 3 which occupies most of the interior space of the ACM since the electro-mechanical portions of the ACM can be highly miniaturized. Tray 3 is removably held in place by some spring means 1 such a~ a spring clip as shown in Fig. 2 which biases the tray 3 aqainst a motor assembly 4 which contains means to move coupons out of the tray through coupon slot 104. A preferred embodiment of coupon tray 3 includes a coupon shoe 3a that pushes against a stack of promotional material 3e, such as coupons, with a constant force using a constant force spring 3b. In Fig. 2, tray 3 is shown approximately one third filled with coupons 3e.
WO91/1~77 PCT/US91/~ ~l 8 20736~7 The remainder of Fig. 2 shows likely positions for a power source 110, such as a plurality of AA batteries, and circuit boards 7 and 8, In the preferred embodiment circuit board 7 controls sensing means 105, e.g. an ultrasonic trans-ducer, and determines when a consumer is in the vicinity of the ACM. In this embodiment, circuit board 8 contains all the logic circuits that control the function of the ACM once sensing means 105 senses the presence of a consumer. Audio means 106 (e.g.
buzzer of speaker) is shown mounted under circuit board 8. In a preferred embodiment a piezo-electric buzzer uses 2 seconds of beeping sound at a frequency of 4.1 XHz to draw attention to the ACM. A frequency of 4.1 KHz is ideal due to the ability of the human ear to pick out that frequency above normal levels of background noise. In another embodiment a speaker is used to produce a 10-15 second audible message (much the same as a radio commercial) to not only draw attention to the ACM but to supply additional promotional information. A sound storage device 206 is provided when the audio mean~ 106 iQ a speaker or the like.
This storage device can be a microca~sQttQ player or a solid state digital device. In a preferred embodiment, a micro-cassette is used and the tape iQ rewound each time the m~ssage is played. A continuous loop cassettQ could be used and rewind-ing would then not be necessary. In the preferred embodiment, the recorded commercial will be repeated every time a person enters in front of the ultra-sonic transducer 105. If visual means are also used to attract the consumer, they would likely be mounted in a visible position rather than under the ACM as the audio means 106 is shown.
Various power sources have been tested with the ACM.
Alkaline batteries with an output of 2000 mAh will have a life of about 60 days if a coupon is ejected every 4 seconds for 12 hours a day. To obtain a much longer battery life, ~ithium batteries with a rating of 4000 mAh may be used. In situations where solar panels 109 are used in con~unction with NI-CAD
batteries, an almost infinite battery life can be expected since the solar panels will continuously recharge the NI-CAD bat-teries. Other sources of power such as AC voltage or AC to DC
Wo9l/1~77 PCT/US91/~ ~1 9 2073~87 PQWer converters may be used without departing from the scope of the invention.
Figs. 3a and 3b show top and front views of the ACM
without the universal mounting brackets 103. Overall dimensions of the ACM may be adjusted to accumulate different amounts and sizes of promotional material without departing from the scope of this invention. A depth of about 3.5" and height of about 2.25" have been found to be qood dimensions for use with most retail store shelves. If these dimensions are chosen, approx-imately 1,000 coupons approximately 1.5" x 2.75~, 70 lb. glossy paper stock can easily be fitted in coupon tray 3. Those skill-ed in the art will appreciate that coupon tray 3 could easily be reconfigured to accommodate coupons on a roll, instead of in a stack.
Fig. 4 shows an overall block diagram of one embodiment of the electronics sections of the ACM. In this embodiment, there are 3 major sections of the ACM electronics: power section A, sensing section B, and main control section C. Power section A distributes power from the batteries 110 and the optional battery charging from the Solar Cell 109 to the other portions of the electronics and is controlled by the optional Auto Shut Off Circuit 113a. The sub~ection A also contains adjusting means 301, 302 for the ACM that tell the ultrasonic circuitry B the limit of how far to look in front of the ACM.
Subsection B details the circuitry that sends and receives the ultrasonic pulses. When this section receives a signal from the Power Control 303 in subsection A, the trans-ducer 105 fires a burst of ultrasonic sound, is switched into receive mode and then waits a preset lenqth of time for an echo.
If an echo is received, then subsection B sends a processed echo pulse to subsection C.
Upon receipt of the processed echo pulsQ, subsection C
then decides whether to turn on the motor 4f, based on whether a coupon is exposed (see Fig. 1). Subsection C also activates buzzer 106 or tape 206 depending on what option is used.
W~1/1~77 PCT~US91/~ ~1 Subsection C can also include an optional mercury tilt switch alarm 309 (such as COMUS, Inc. part #CM 14-0) to detect when the ACM is removed from the shelf. This tilt switch 309 will turn on the buzzer 106 continuously until the ACM is re-turned to a lqvel position.
In the preferred embodiment, audio means 106 is a buzzer with a frequency of 4.1 KHz. This frequency was chosen because of the ability of the human ear to pick out that fre-quency above normal levels of background noise.
In operation of the illustrated embodiment, power control 303 from subsection A, sends a pulse to the power inter-face circuit 24 which sends power to the electronics in,sub-section B. When power is turned on, clock 23 sends a frequency of 50 KHz through the digital section 22 and out through the power interface circuit 24 for amplification. This amplified 50 XHz frequency is then sent to the ultrasonic transducer 105 that produces a burst of ultrasonic sound emitted directly in front of the ACM. The transducer 105 then changes from a transmitter to a receiver and waits for any echo pulse that may be detected.
Sound travels at a rate of 1 foot every .89 milliseconds in air and as a result, the effective range of the ACM can be adjusted by keeping the transducer 105 in the receive mode for a set period of time. Thus, a target that is 10 feet away from the ACM would cause an echo to be received 17.8 ms after the transducer 105 transmitted it. [10 feet out + 10 feet back results in a total travel of 20 feet x .89 ms = 17.8 ms.] To reject any targets further than 10 feet away, the pulse from the sensor range adjustment module 302 in subsection A will shut off power to the transducer circuit after 18 ms. By shutting off the circuit, any echo that comes in from further than 10 feet will be ignored, hence a limit on the range. This ran~e can easily be adjusted between 1-10 feet to allow for the rej~ction of opposing shelves or objects that need to be ignored by the ACM.
-V ~ IV~ I ~ PCT/US91/~ ~1 - The ultra-sonic transducer 105 sends out a high power burst of sound beyond the range of human hearing during the transmit cycle, however sound intensity decreases by th~ inverse square law. This means that the intensity of the echo pu!se is many times weaker than the transmitted pulse. To account for this weaker pulse, the detector circuit that detects and pro-cesses the echo pulse must be able to increase its gain sen-sitivity to detect low intensity echoes. To do this, the digi-tal section 22 modifies the sensitivity of the analog circuit 21 using the gain + bandwidth control while the transducer awaits the echo. The gain is changed based on time because the longer it takes to receive an echo, the weaker the echo signal will be.
When the analog circuit 21 receives an echo, it pro-cesses the very weak echo pulse into a stronger pulse called the processed echo. This signal is sent to the digital section 22 and the digital section then turns off the gain + bandwidth control. This processed echo pulse also begins a series of events in the electronics of subsection C. Those skilled in the art will realize that there are other methods of detecting the proximity of a consumer such as with infrared detectors. How-ever, the use of different detectors does not go beyond the scope of this invention.
Subsection C shows a block diagram of one embodiment of the coupon dispensing and audio/visual electronics. This circuit becomes active upon receipt of a processed echo pulse from subsection B. Several things take place simultaneously within this subsection when a processed echo pulse is received.
Power is supplied to the coupon sensor 107 via the power control to sensor module 304. This results in a "coupon/no coupon"
indication from the sensor 107. In the event that a coupon is still in the exit slot (see, e.g., Fig. 1), the sensor 107 will indicate a "coupon" to the motor control timer 6 and the motor 4f will not be turned on and no additional coupon will be dis-pensed. In the event that no coupon is in the exit slot (see, e.g. Fig. 3a), then the sensor 107 will send a "no coupon"
signal to the motor power control timer 6 and this module will WO91/1~77 PCT/US91/~ ~1 12 20735~7 turn on the motor 4f for a pre-set length of time to eject a coupon from the coupon tray 3 (described in further detail with reference to Figs. 6 and 7) out through the exit slot to be removed by a consumer.
Another event that is triggered by the presence of a processed echo pulse is the activation of audio/visual means 106, shown here as the buzzer discussed above. The processed echo pulse is received by the buzzer timer control 30~ that turns on both th- freguency generator 10 and the pulse generator 11. The frequency generator module 10 is a clock oscillator that is set at 4.1 KHz and is gated to the buzzer 106 by the pulses from the pulse generator module 11. The resulting signal to the buzzer 106 is a 2 second long "beeping" sound where for 2 seconds the buzzer 106 turns on and off quickly to produce a beeping sound. This beeping sound is used to attract attention to the ACM.
The optional alarm circuit is also shown in subsection C. The mercury tilt switch module 309 is used to override the buzzer timer module 307 and turn on the buzzer 106 any time the ACM is not in a horizontal position. The buzzer 106 will con-tinue to beep as long as the ACM is tilted. Those skilled in the art may realize other methods of tamper detection without departing from the scope of this invention.
An optional method of attracting attention to the ACM, as well as supplying additional promotional information to the consumer is the addition of a 10-15 second audible message that is played through a speaker in the ACM. This optional taped message 206 can be a looped taped message on magnetic audio tape that will begin upon receipt of the processed echo pulse. The message will play through to its entirety and then a strip of metal on the tape will be used to reference the start of the message and will cue up the tape for the next time a processed echo pulse is received. Other methods of message storage/
playback such as solid state digital recording or like methods are within the scope of this invention.
/ t P~'l'/U~l/W241 13 21~735~7 ~~ Fig. 5 shows a block diagram of the logic steps the Automatic Coupon Machine ACM follows during operation of the above-described preferred embodiment. The beginning of the sequence starts with the transmission 401 of an ultra-sonic pulse. At this point the ultra-sonic transducer is in the "transmit" mode. Immediately following the transmission, there is a delay 402 of 1.5 ms before the ultra-sonic transducer is changed to the "receiver" mode. This delay is used to reject the echo caused by the transducer cover grill at the front of the ACM. While the transducer is in the receiver mode, it waits for an echo pulse. A first branch 403 decides if an echo has been sensed. If "NO", the ACM then proceeds to a second branch 404 to decide if the timer has expired. This timer sets the range of the transducer. If the timer hasn't expired, then the ACM returns to branch 403 and continues to wait for an echo. If the timer has expired, then the ACM wait~ 409 for the fire rate frequency clock to time out .5 - 4 seconds and then mo~es up to 418 set the range timer 2-18 ms and then sends off anothel ultrasonic burst 401 to begin the process all over aqain. If, however, any echo is returned at branch 403, then there are 3 paths the ACM goes to simultaneously. The first path decides 405 if there is a coupon blocking the coupon sensor. If "NO", then the ACM sends power 406 to the motor to dispense a coupon.
The ACM then times 407 how lonq the power is sent to the Motor (250-300 ms to dispense one coupon) and when that time is ex-pired, the ACM shuts off the motor 408 and then proceeds to wait 409 for the next fire cycle. If there is a coupon blocking the optical sensor 405, then the ACM does nothing to the motor.
With a "YES" decision at branch 403 (echo returned), the ACM also applies power 410 to the buzzer or 413 to the audio message. The ACM then allows 411 either 2 seconds of beeping or it waits 414 for the message to play to the end. The ACM then turns off power 412 to the buzzer or turns off power 415 to the message circuit and waits 409 for the next firing cycle.
When the firing cycle wait 409 time~ out (typically .5 - 4 seconds), then a timer is set 418 to determine the range of the ACM. The setting 418 of this timer determines how long v~ 1/U~i~l/W;~4l 14 2073~7 ~the ultrasonic transducer will remain in the receive mode (typi-cally 2 - 18 ms). Once this timer is set 418 then the process begins all over again with the ultrasonic transducer firing a burst of ultrasonic sound 401.
Fig. 6 shows a detailed drawing of an exemplary coupon tray 3 and its components. Fig. 6a is a top view; 6b is a side elevation looking in the direction B shown in Fig. 6a; a.~ Fig.
6c is a side elevation looking in the direction C shown in Fig.
6a.
The illustrated coupon tray 3 is designed to hold up to 1000 individual pieces of promotional material with dimensions of 2.75" W x 1.62" H x .005" thick. This promotional material is placed inside the coupon tray after removing tray cover 3c.
The promotional material coupons 3e (see Fig. 2) are pressed between the front plate 3m and coupon shoe 3a and held by a con~tAnt ~orce sprlng 3b secured to th- coupon sho~ wlth rod 3i and attached to the front Or the coupon tray with a spring pin 3p. I~f a non-constant force ~pring w~re used pushing aqainst the back of the shoe, then there would be a varying force depending upon how many coupons are left in the tray. This would be a problem in pushing the coupons out of the tray.
Therefore, a constant force spring 3b is used in this embodiment. This spring 3b rides along track 3k to keep the spring away from the edge of the coupons.
The coupon shoe 3a ride~ along tracks 31 and is held in place with rod 3i. The coupons are pressed up against the coupon tray faceplate 3m which has an opening cut in it to allow for a roller assembly to come into contact with the next avail-able coupon. When the ACM turns on the motor to dispense a coupon, the roller assembly pushe~ the next available coupon down into the nose 3s of the coupon tray and against the coupon separator 3h and coupon guide posts 3g. The separator is used to separate the next available coupon from the coupons remaining in the tray while the coupon guide posts guide the coupon into the dispensing chute 3f. This dispensing chute guides the W~91/1~77 PCT/US91/~ ~l 1S . 2073~7 coup~n out through the coupon exit slot in the front of the cover assembly. (See Fig. 1.) Also located on the coupon tray face plate 3m is locator slot 3t. This slot is used to secure the front of the coupon tray to the backplate of the A~M. (See Fig. 2.) An-other slot 3d is located in the ~OU~G~I tray backplate 3r. This slot 3d is used to align the rear of the coupon tray with the back plate of the ACM. (See Fig. 2.) Fig. 7 shows the motor assembly for moving coupons out of the coupon tray as described above. The motor and its associated assembly are mounted on a main support plate 4a.
This support plate can be secured to the back plate of the ACM
with the use of machine screws t~readed into the back plate.
(See Fig. 2.) The motor 4f can be a Port-E-Scap U.S., Inc.
(Hauppauge, New York) Model #MU-915L61-205-98.70 which is a hollow core motor that has a very small inertial load thus requiring very little current with respect to an iron core motor. This type of motor lends itself well for this design because it has a right angle geared down head with a gear ratio of 98.7:1. This right angle drive allows the motor to be mount-ed parallel with coupons to minimize the width of the ACM.
Those skilled in the art may realize other methods of dispensing the coupons from the coupon tray, such as with the use of a solenoid, without departing from the scope of this invention.
Attached to the output shaft of the motor is a roller assembly 4c. This roller assembly has an outside coating of rubber to maximize the friction between the coupon and the roller so there is no slippage when dispensing a coupon. Also attached to the motor 4f is the motor mounting bracket 4b. This bracket is attached to the motor using screws 4~. This motor mounting bracket it attached to the main support plate 4a using a screw 4d and a spacer 4e. Screw 4d is ad~usted to allow for free movement of the motor bracket 4b pivoting on the screw 4d.
Thread lock is used between screw 4d and the main support plate ~V Yl/ I~/ / PCT/US9l/~ ~1 4a to keep the screw 4d from tightening on the motor. Spring 4g is attached between the motor support bracket 4b and spring post 4h to keep tension between the roller 4c and the next coupon in the coupon tray.
Fig. 8 shows a side view of the ACM Mountirg Clamps.
This universal mounting clamp 103 comprises top plate 103b which is fastened to the back plate or i8 part of the back plate of ACM 101 and is used as the top portion of the mounting clamp.
Bottom plate 103a is attached to top plate 103b or the back plate of ACM 101 and becomes the bottom support for the mounting clamp. To secure the ACM 101 to the shelf, screw 103c is threaded through the bottom support plate 103a and is tightened on shelf 102. A typical retail store shelf is illustrated here, however, with this type of universal clamp, the ACM 101 can be attached to almost any type of shelf. This clamp design also allows for the ACM to be as close to the front of the shelf as possible. This eliminates the problem of the ACM being too far from the shelf, thus reducing the chance of the ACM sticking out too far into the aisle. The screw 103c can be Hex Head or Torquex Head variety to reduce the chance of tampering. Those knowledgeable in the field may recognize other methods of mount-ing the ACM such as the use of a free standing support without deviating from the scope of this invention.
Although the invention is described and illustrated with reference to a plurality of embodiments thereof, it is to be expressly understood that it is in no way limited to the disclosure of such preferred embodiments but is capable of numerous modifications within the scope of the appended claims.
The invention relates to a machine for automatically dispensing coupons or the like. More particularly, the invention concerns an automatic coupon dispensing machine with means for sensing proximity of a consumer and means for attracting the attention of the consumer.
In recent years, the number and value of grocery coupons distributed has steadily increased yet consumer redemption has steadily decreased.
Consumer behaviour and the understanding of it has led to the need for Point-of-Sales marketing. In 1988 the Point-of-Purchasing Advertising Institute surveyed 50,000 consumers in the act of buying and found that:
90% had not looked at promotional circulars 86% had not heard broadcast messages 80% were not redeeming coupons 75 % had not checked store ads Moreover, media used for advertising includes prime time network television. Over the last decade, however, the networks' share of the audience has dropped from 92% to 67% according to A.C. Nielson Co.
and the daytime audience has fallen from 78% down to 57%. Yet the cost of 30 seconds of prime time network air time has increased 85 % .
See, Stalking the New Consumer, Business Week, August 28, 1989.
A study was conducted in 1988 to review the redemption rates of grocery coupons for the year 1987 compared with 1988. See, Progressive Grocer, October 1988. The results of this study are as follows:
6 ~ 7 Source of Coupons% Redemption % Change Daily Newspaper 4.0% -25%
Sunday Newspaper 4.8 % -27 %
M~g~7ines 5.4 % -19 %
Direct Mail 5.8% -28%
Instant On-Pack 31.0% + 11 %
It can be seen that the instant on-pack coupon (instant redemption coupon attached to a product and redeemed at the check out counter) shows an impressive 31% redemption rate and is the only coupon distribution vehicle that has shown an increase in redemption since 1984. Id.
Consumer research also shows that: "Two thirds of all buying decisions are made in the store." Thus, advertisers should concentrate their efforts on in-store promotion.
Under these conditions, it is appal~nt that a point-of-sales marketing program holds the greatest redemption percentage of any other coupon distribution method in use today. A clear indication of this is the 300-600% increase in product movement typically experienced on the day of an in-store product demonstration.
Manufacturers and retailers are thus challenged to offer an innovative point-of-sales promotional method that satisfies the stringent convenience requirements of consumers while generating greater sustained levels of product awareness. The Automatic Coupon Machine of the present invention provides the consumer with convenience, value, and time savings.

SUMMARY OF TH~ I~v~lIO~
Accordingly, it is an object of the invention to provide an improved method for distributing manufacturers' or retailers' promotional material directly to the consumer at the time the decision to purchase is being made by the consumer.
Another object of the invention is to provide a dis-pensing device in a small, self contained enclosure which can be located in the vicinity of a relevant product display without detracting from the product display.
A further object of the invention is to attract the attention of consumers as they approach or pass a product dis-play and to visibly dispense promotional material such as a coupon.
The above and other objects are achieved by the inven-tive Automatic Coupon Machine (ACM), for automatic dispensing of promotional material. ~he preferred embodiment of the ACM is designed to be mounted on the front portion of a retail shelf directly in front of the product specified on the promotional material to be dispensed.

DET~TTT~'D DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to Fig. 1, a preferred embodiment of the Automatic Coupon M~Ch ine (ACM) 101 is shown mounted on a retail store shelf 102 with the use of brackets 103. The overall dimensions of the ACM 101 are preferably such that it may be so mounted on display shelf 102 without eclipsing products displayed on the shelf. Nevertheless, the ACM can be configured several different ways as will become apparent in the following description.
The preferred embodiment of the ACM 101 is provided with a coupon dispensing slot 104, a sensor 105 to sense the W~YI/1~77 PCT/US91/~ ~1 6 20~36~7 proXImity of a consumer, and audio/visual means 106 to attract the attention of a consumer to the ACM. In the embodiment shown in Fig. 1, audio/visual means 106 is simply a buzzer or other sounding device and sensing means 105 is an ultrasonic trans-ducer. However, other audio/visual means and sensing means may be employed, for example a visual display of some type and an infrared sensor.
It is also preferable that the ACM contain s~me means 107 for sensing the presence of a coupon 108 in the coupon dispensing slot 104.
The embodiment shown in Fig. 1 is also provided with a solar cell 109 for charging batteries 110 tFig. 2), although other sources of power may be used.
Access to the ACM is preferably obtained by way of some lock and key means 111, 112 as shown by example in Fig. 1.
The embodiment shown in Fig. 1 is also optionally provided with automatic shut off means 113, in the form of a photo transistor which senses when ambient lighting is turned on and off.
Fig. 2 shows the internal components of the exemplary ACM of Fig. 1. All the internal components are contained within housing 115 which is provided with mounting means 103 as dis-cussed briefly above and in further detail with reference to Fig. 8. Housing 115 can be made of ABS plastic or any other suitable material.
Power source 110 is preferably nickel cadmium batteries which can be charged by solar cell 109, but other types of batteries may be used without charging, or a transformer may be used to secure power for the ACM from an AC line.
Sensing means 105 is preferably an ultra-sonic trans-ducer such as a Polaroid series 7000 (Needham Heights, Massachusetts) although an infrared sensing means could also be used.
W~ Yl/ 1~ / / PCT/US91/~ ~1 ~ Coupon sensing means 107 is preferably an optical sensor such as an Omron (now, Sen-I-Sys, Plano, Texas) part number EE-SX-1023-Wl which detects the presence of an exposed coupon 108 in coupon slot 104.
Audio/visual means 106 may be a piezo-electric buzzer such as that manufactured by Monaco Components, Inc. (Glen Head, New York) part #SEP-1112 or a speaker such as Panasonic (Secaucus, New Jersey) part number 3P108S, to produce either a beeping sound or a short recorded message to attract the atten-tion of consumers as they come within proximity of the ACM.
Other audio/visual means such as LEDs, LCDs, electroluminescent panels, video displays or the like can also be used within the scope of this invention.
Access to the ACM may be through a hinge 116 provided at the rear of the housing 115 whereby the rear panel of the housing is opened when lock 111 is activated with key 112.
Other access means could be easily provided and this is shown only as one example.
A preferred embodiment of the ACM also includes a photo-transistor 113 to detect the intensity o~ ambient light.
When the location of the ACM becomes dark, such as when a retail establishment closes for the evening, the photo-transistor 113 will automatically shut off the ACM to conserve power and extend battery life.
Fig. 2 also shows a coupon tray 3 which occupies most of the interior space of the ACM since the electro-mechanical portions of the ACM can be highly miniaturized. Tray 3 is removably held in place by some spring means 1 such a~ a spring clip as shown in Fig. 2 which biases the tray 3 aqainst a motor assembly 4 which contains means to move coupons out of the tray through coupon slot 104. A preferred embodiment of coupon tray 3 includes a coupon shoe 3a that pushes against a stack of promotional material 3e, such as coupons, with a constant force using a constant force spring 3b. In Fig. 2, tray 3 is shown approximately one third filled with coupons 3e.
WO91/1~77 PCT/US91/~ ~l 8 20736~7 The remainder of Fig. 2 shows likely positions for a power source 110, such as a plurality of AA batteries, and circuit boards 7 and 8, In the preferred embodiment circuit board 7 controls sensing means 105, e.g. an ultrasonic trans-ducer, and determines when a consumer is in the vicinity of the ACM. In this embodiment, circuit board 8 contains all the logic circuits that control the function of the ACM once sensing means 105 senses the presence of a consumer. Audio means 106 (e.g.
buzzer of speaker) is shown mounted under circuit board 8. In a preferred embodiment a piezo-electric buzzer uses 2 seconds of beeping sound at a frequency of 4.1 XHz to draw attention to the ACM. A frequency of 4.1 KHz is ideal due to the ability of the human ear to pick out that frequency above normal levels of background noise. In another embodiment a speaker is used to produce a 10-15 second audible message (much the same as a radio commercial) to not only draw attention to the ACM but to supply additional promotional information. A sound storage device 206 is provided when the audio mean~ 106 iQ a speaker or the like.
This storage device can be a microca~sQttQ player or a solid state digital device. In a preferred embodiment, a micro-cassette is used and the tape iQ rewound each time the m~ssage is played. A continuous loop cassettQ could be used and rewind-ing would then not be necessary. In the preferred embodiment, the recorded commercial will be repeated every time a person enters in front of the ultra-sonic transducer 105. If visual means are also used to attract the consumer, they would likely be mounted in a visible position rather than under the ACM as the audio means 106 is shown.
Various power sources have been tested with the ACM.
Alkaline batteries with an output of 2000 mAh will have a life of about 60 days if a coupon is ejected every 4 seconds for 12 hours a day. To obtain a much longer battery life, ~ithium batteries with a rating of 4000 mAh may be used. In situations where solar panels 109 are used in con~unction with NI-CAD
batteries, an almost infinite battery life can be expected since the solar panels will continuously recharge the NI-CAD bat-teries. Other sources of power such as AC voltage or AC to DC
Wo9l/1~77 PCT/US91/~ ~1 9 2073~87 PQWer converters may be used without departing from the scope of the invention.
Figs. 3a and 3b show top and front views of the ACM
without the universal mounting brackets 103. Overall dimensions of the ACM may be adjusted to accumulate different amounts and sizes of promotional material without departing from the scope of this invention. A depth of about 3.5" and height of about 2.25" have been found to be qood dimensions for use with most retail store shelves. If these dimensions are chosen, approx-imately 1,000 coupons approximately 1.5" x 2.75~, 70 lb. glossy paper stock can easily be fitted in coupon tray 3. Those skill-ed in the art will appreciate that coupon tray 3 could easily be reconfigured to accommodate coupons on a roll, instead of in a stack.
Fig. 4 shows an overall block diagram of one embodiment of the electronics sections of the ACM. In this embodiment, there are 3 major sections of the ACM electronics: power section A, sensing section B, and main control section C. Power section A distributes power from the batteries 110 and the optional battery charging from the Solar Cell 109 to the other portions of the electronics and is controlled by the optional Auto Shut Off Circuit 113a. The sub~ection A also contains adjusting means 301, 302 for the ACM that tell the ultrasonic circuitry B the limit of how far to look in front of the ACM.
Subsection B details the circuitry that sends and receives the ultrasonic pulses. When this section receives a signal from the Power Control 303 in subsection A, the trans-ducer 105 fires a burst of ultrasonic sound, is switched into receive mode and then waits a preset lenqth of time for an echo.
If an echo is received, then subsection B sends a processed echo pulse to subsection C.
Upon receipt of the processed echo pulsQ, subsection C
then decides whether to turn on the motor 4f, based on whether a coupon is exposed (see Fig. 1). Subsection C also activates buzzer 106 or tape 206 depending on what option is used.
W~1/1~77 PCT~US91/~ ~1 Subsection C can also include an optional mercury tilt switch alarm 309 (such as COMUS, Inc. part #CM 14-0) to detect when the ACM is removed from the shelf. This tilt switch 309 will turn on the buzzer 106 continuously until the ACM is re-turned to a lqvel position.
In the preferred embodiment, audio means 106 is a buzzer with a frequency of 4.1 KHz. This frequency was chosen because of the ability of the human ear to pick out that fre-quency above normal levels of background noise.
In operation of the illustrated embodiment, power control 303 from subsection A, sends a pulse to the power inter-face circuit 24 which sends power to the electronics in,sub-section B. When power is turned on, clock 23 sends a frequency of 50 KHz through the digital section 22 and out through the power interface circuit 24 for amplification. This amplified 50 XHz frequency is then sent to the ultrasonic transducer 105 that produces a burst of ultrasonic sound emitted directly in front of the ACM. The transducer 105 then changes from a transmitter to a receiver and waits for any echo pulse that may be detected.
Sound travels at a rate of 1 foot every .89 milliseconds in air and as a result, the effective range of the ACM can be adjusted by keeping the transducer 105 in the receive mode for a set period of time. Thus, a target that is 10 feet away from the ACM would cause an echo to be received 17.8 ms after the transducer 105 transmitted it. [10 feet out + 10 feet back results in a total travel of 20 feet x .89 ms = 17.8 ms.] To reject any targets further than 10 feet away, the pulse from the sensor range adjustment module 302 in subsection A will shut off power to the transducer circuit after 18 ms. By shutting off the circuit, any echo that comes in from further than 10 feet will be ignored, hence a limit on the range. This ran~e can easily be adjusted between 1-10 feet to allow for the rej~ction of opposing shelves or objects that need to be ignored by the ACM.
-V ~ IV~ I ~ PCT/US91/~ ~1 - The ultra-sonic transducer 105 sends out a high power burst of sound beyond the range of human hearing during the transmit cycle, however sound intensity decreases by th~ inverse square law. This means that the intensity of the echo pu!se is many times weaker than the transmitted pulse. To account for this weaker pulse, the detector circuit that detects and pro-cesses the echo pulse must be able to increase its gain sen-sitivity to detect low intensity echoes. To do this, the digi-tal section 22 modifies the sensitivity of the analog circuit 21 using the gain + bandwidth control while the transducer awaits the echo. The gain is changed based on time because the longer it takes to receive an echo, the weaker the echo signal will be.
When the analog circuit 21 receives an echo, it pro-cesses the very weak echo pulse into a stronger pulse called the processed echo. This signal is sent to the digital section 22 and the digital section then turns off the gain + bandwidth control. This processed echo pulse also begins a series of events in the electronics of subsection C. Those skilled in the art will realize that there are other methods of detecting the proximity of a consumer such as with infrared detectors. How-ever, the use of different detectors does not go beyond the scope of this invention.
Subsection C shows a block diagram of one embodiment of the coupon dispensing and audio/visual electronics. This circuit becomes active upon receipt of a processed echo pulse from subsection B. Several things take place simultaneously within this subsection when a processed echo pulse is received.
Power is supplied to the coupon sensor 107 via the power control to sensor module 304. This results in a "coupon/no coupon"
indication from the sensor 107. In the event that a coupon is still in the exit slot (see, e.g., Fig. 1), the sensor 107 will indicate a "coupon" to the motor control timer 6 and the motor 4f will not be turned on and no additional coupon will be dis-pensed. In the event that no coupon is in the exit slot (see, e.g. Fig. 3a), then the sensor 107 will send a "no coupon"
signal to the motor power control timer 6 and this module will WO91/1~77 PCT/US91/~ ~1 12 20735~7 turn on the motor 4f for a pre-set length of time to eject a coupon from the coupon tray 3 (described in further detail with reference to Figs. 6 and 7) out through the exit slot to be removed by a consumer.
Another event that is triggered by the presence of a processed echo pulse is the activation of audio/visual means 106, shown here as the buzzer discussed above. The processed echo pulse is received by the buzzer timer control 30~ that turns on both th- freguency generator 10 and the pulse generator 11. The frequency generator module 10 is a clock oscillator that is set at 4.1 KHz and is gated to the buzzer 106 by the pulses from the pulse generator module 11. The resulting signal to the buzzer 106 is a 2 second long "beeping" sound where for 2 seconds the buzzer 106 turns on and off quickly to produce a beeping sound. This beeping sound is used to attract attention to the ACM.
The optional alarm circuit is also shown in subsection C. The mercury tilt switch module 309 is used to override the buzzer timer module 307 and turn on the buzzer 106 any time the ACM is not in a horizontal position. The buzzer 106 will con-tinue to beep as long as the ACM is tilted. Those skilled in the art may realize other methods of tamper detection without departing from the scope of this invention.
An optional method of attracting attention to the ACM, as well as supplying additional promotional information to the consumer is the addition of a 10-15 second audible message that is played through a speaker in the ACM. This optional taped message 206 can be a looped taped message on magnetic audio tape that will begin upon receipt of the processed echo pulse. The message will play through to its entirety and then a strip of metal on the tape will be used to reference the start of the message and will cue up the tape for the next time a processed echo pulse is received. Other methods of message storage/
playback such as solid state digital recording or like methods are within the scope of this invention.
/ t P~'l'/U~l/W241 13 21~735~7 ~~ Fig. 5 shows a block diagram of the logic steps the Automatic Coupon Machine ACM follows during operation of the above-described preferred embodiment. The beginning of the sequence starts with the transmission 401 of an ultra-sonic pulse. At this point the ultra-sonic transducer is in the "transmit" mode. Immediately following the transmission, there is a delay 402 of 1.5 ms before the ultra-sonic transducer is changed to the "receiver" mode. This delay is used to reject the echo caused by the transducer cover grill at the front of the ACM. While the transducer is in the receiver mode, it waits for an echo pulse. A first branch 403 decides if an echo has been sensed. If "NO", the ACM then proceeds to a second branch 404 to decide if the timer has expired. This timer sets the range of the transducer. If the timer hasn't expired, then the ACM returns to branch 403 and continues to wait for an echo. If the timer has expired, then the ACM wait~ 409 for the fire rate frequency clock to time out .5 - 4 seconds and then mo~es up to 418 set the range timer 2-18 ms and then sends off anothel ultrasonic burst 401 to begin the process all over aqain. If, however, any echo is returned at branch 403, then there are 3 paths the ACM goes to simultaneously. The first path decides 405 if there is a coupon blocking the coupon sensor. If "NO", then the ACM sends power 406 to the motor to dispense a coupon.
The ACM then times 407 how lonq the power is sent to the Motor (250-300 ms to dispense one coupon) and when that time is ex-pired, the ACM shuts off the motor 408 and then proceeds to wait 409 for the next fire cycle. If there is a coupon blocking the optical sensor 405, then the ACM does nothing to the motor.
With a "YES" decision at branch 403 (echo returned), the ACM also applies power 410 to the buzzer or 413 to the audio message. The ACM then allows 411 either 2 seconds of beeping or it waits 414 for the message to play to the end. The ACM then turns off power 412 to the buzzer or turns off power 415 to the message circuit and waits 409 for the next firing cycle.
When the firing cycle wait 409 time~ out (typically .5 - 4 seconds), then a timer is set 418 to determine the range of the ACM. The setting 418 of this timer determines how long v~ 1/U~i~l/W;~4l 14 2073~7 ~the ultrasonic transducer will remain in the receive mode (typi-cally 2 - 18 ms). Once this timer is set 418 then the process begins all over again with the ultrasonic transducer firing a burst of ultrasonic sound 401.
Fig. 6 shows a detailed drawing of an exemplary coupon tray 3 and its components. Fig. 6a is a top view; 6b is a side elevation looking in the direction B shown in Fig. 6a; a.~ Fig.
6c is a side elevation looking in the direction C shown in Fig.
6a.
The illustrated coupon tray 3 is designed to hold up to 1000 individual pieces of promotional material with dimensions of 2.75" W x 1.62" H x .005" thick. This promotional material is placed inside the coupon tray after removing tray cover 3c.
The promotional material coupons 3e (see Fig. 2) are pressed between the front plate 3m and coupon shoe 3a and held by a con~tAnt ~orce sprlng 3b secured to th- coupon sho~ wlth rod 3i and attached to the front Or the coupon tray with a spring pin 3p. I~f a non-constant force ~pring w~re used pushing aqainst the back of the shoe, then there would be a varying force depending upon how many coupons are left in the tray. This would be a problem in pushing the coupons out of the tray.
Therefore, a constant force spring 3b is used in this embodiment. This spring 3b rides along track 3k to keep the spring away from the edge of the coupons.
The coupon shoe 3a ride~ along tracks 31 and is held in place with rod 3i. The coupons are pressed up against the coupon tray faceplate 3m which has an opening cut in it to allow for a roller assembly to come into contact with the next avail-able coupon. When the ACM turns on the motor to dispense a coupon, the roller assembly pushe~ the next available coupon down into the nose 3s of the coupon tray and against the coupon separator 3h and coupon guide posts 3g. The separator is used to separate the next available coupon from the coupons remaining in the tray while the coupon guide posts guide the coupon into the dispensing chute 3f. This dispensing chute guides the W~91/1~77 PCT/US91/~ ~l 1S . 2073~7 coup~n out through the coupon exit slot in the front of the cover assembly. (See Fig. 1.) Also located on the coupon tray face plate 3m is locator slot 3t. This slot is used to secure the front of the coupon tray to the backplate of the A~M. (See Fig. 2.) An-other slot 3d is located in the ~OU~G~I tray backplate 3r. This slot 3d is used to align the rear of the coupon tray with the back plate of the ACM. (See Fig. 2.) Fig. 7 shows the motor assembly for moving coupons out of the coupon tray as described above. The motor and its associated assembly are mounted on a main support plate 4a.
This support plate can be secured to the back plate of the ACM
with the use of machine screws t~readed into the back plate.
(See Fig. 2.) The motor 4f can be a Port-E-Scap U.S., Inc.
(Hauppauge, New York) Model #MU-915L61-205-98.70 which is a hollow core motor that has a very small inertial load thus requiring very little current with respect to an iron core motor. This type of motor lends itself well for this design because it has a right angle geared down head with a gear ratio of 98.7:1. This right angle drive allows the motor to be mount-ed parallel with coupons to minimize the width of the ACM.
Those skilled in the art may realize other methods of dispensing the coupons from the coupon tray, such as with the use of a solenoid, without departing from the scope of this invention.
Attached to the output shaft of the motor is a roller assembly 4c. This roller assembly has an outside coating of rubber to maximize the friction between the coupon and the roller so there is no slippage when dispensing a coupon. Also attached to the motor 4f is the motor mounting bracket 4b. This bracket is attached to the motor using screws 4~. This motor mounting bracket it attached to the main support plate 4a using a screw 4d and a spacer 4e. Screw 4d is ad~usted to allow for free movement of the motor bracket 4b pivoting on the screw 4d.
Thread lock is used between screw 4d and the main support plate ~V Yl/ I~/ / PCT/US9l/~ ~1 4a to keep the screw 4d from tightening on the motor. Spring 4g is attached between the motor support bracket 4b and spring post 4h to keep tension between the roller 4c and the next coupon in the coupon tray.
Fig. 8 shows a side view of the ACM Mountirg Clamps.
This universal mounting clamp 103 comprises top plate 103b which is fastened to the back plate or i8 part of the back plate of ACM 101 and is used as the top portion of the mounting clamp.
Bottom plate 103a is attached to top plate 103b or the back plate of ACM 101 and becomes the bottom support for the mounting clamp. To secure the ACM 101 to the shelf, screw 103c is threaded through the bottom support plate 103a and is tightened on shelf 102. A typical retail store shelf is illustrated here, however, with this type of universal clamp, the ACM 101 can be attached to almost any type of shelf. This clamp design also allows for the ACM to be as close to the front of the shelf as possible. This eliminates the problem of the ACM being too far from the shelf, thus reducing the chance of the ACM sticking out too far into the aisle. The screw 103c can be Hex Head or Torquex Head variety to reduce the chance of tampering. Those knowledgeable in the field may recognize other methods of mount-ing the ACM such as the use of a free standing support without deviating from the scope of this invention.
Although the invention is described and illustrated with reference to a plurality of embodiments thereof, it is to be expressly understood that it is in no way limited to the disclosure of such preferred embodiments but is capable of numerous modifications within the scope of the appended claims.
