1. Field of the Invention
The invention is related to a data port and, more particularly, to a multifunction intelligent data port having a computer interface between a digital service network and a utility user's home electronics. The invention further relates to remote utility meter reading and remote load management, as well as telecommunications, Internet access and methods to provide secure digital transactions.
2. Related Art
A customer of an electric company typically has an electric meter located at the customer's structure or site of distribution of electrical power. The customer's structure may be, for example, the customer's home or office. The electric meter is owned by the electric company and is installed in a meter box, which holds the electric meter. The meter box may be provided and owned by the building owner, the utility or the landlord.
The prior art includes a number of references that disclose utility meters with associated electronics.
U.S. Pat. No. 4,455,453 issued to Parasekvakos et al., incorporated herein by reference, discloses an apparatus for remote meter reading, wherein a remote unit, preferably located inside a house, periodically initiates a telephone call to a utility company and communicates power usage information.
U.S. Pat. No. 4,803,632 issued to Frew et al., incorporated herein by reference, discloses a utility meter having a CPU, a display, and associated circuitry which may be located in the conventional meter location. Frew also discloses a remote unit located inside the house which displays the meter information and allows the customer to pay his bill by credit card. The remote unit communicates with the CPU over the house's power lines. The meter in Frew can be read by a meter reader either through the house's power lines or via optical coupling at the meter, but does not contain a multifunction data port with a voice and video interface, or other attendance electronics to provide broadband digital services with the utility and/or the Internet Service Provider (ISP) as taught by the subject invention. Similarly, Karlsson et al (U.S. Pat. No. 4,442,492) has disclosed a limited data port interface and computer than can read a meter an transmit this information back to the utility over the power lines. Karlsson can also receive a change in power rates from the utility and transmit both the cost and power use to a device in the user's household. Furthermore, Frew et al. (U.S. Pat. No. 4,803,632) has disclosed a device in the home that can read credit or debit cards and allows the customer to pay their power bill over the communication network. Combining Karlsson and Frew teaches a device or devices that include(s) a computer and two-way communication of utility use and billing data between the utility and its customer. The Frew and Karlsson devices have electronics primarily directed to meter reading and processing utility billing data. The purpose of the Frew patent, as stated, is “utility meter system having all of the functions and providing all of the information of interest to customers and to the utility company.” The 16 digit alphanumeric display in the Frew patent is refreshed 1024 times/second. These very small data rates are orders of magnitude lower than the required rates for the multifunction data port of the present invention, and do not teach the very significant elements of the subject invention including the voice and video processor and other multiple interfaces to both the utility and the utility user's internal electronics and appliances. The specifications in the current patent application describe features in the multifunction data port that clearly distinguish it from a device like the combination of Karksson and Frew, or either such device.
The present invention distinguishes between the limited data rates and electronics needed for automatic meter reading and the broad band Internet communication rates specified for the multifunction data port. While one potential function of the multifunction data port in the present invention is receiving and communicating data from the utility meter, it is the other features of the invention that make it unique in the art. The multifunction data port in the present invention can analyze, store and report meter and load usage information as well as communicate with the utility user's internal electronics and appliances through voice and video interfaces. The current cost to an electric utility to read their meters on-site can be as low as $12-20 per year, while potential revenues from other features offered by the multifunction data port to the utility user can easily be over 100 times larger. The subject invention with its multiple interfaces differ in purpose, design, utility, novelty and data rates from other remote reading meters and devices such as Karlsson and Frew.
U.S. Pat. No. 4,804,957 issued to Selph et al, incorporated herein by reference, discloses a utility meter using a microprocessor-based circuit and Hall effect current sensors to measure power usage. In Selph, the meter may be read by either remote interrogation via a telephone link or serial communication. Selph also discloses a networked submetering arrangement useful in apartment buildings and the like.
U.S. Pat. No. 4,904,995 issued to Bonner et al., incorporated herein by reference, discloses a remote meter reading apparatus which is designed to retrofit existing electric meters with a transponder capable of communicating power usage information to the electric company over the electric power distribution system.
It is also known in the art to utilize a house's power lines for communication between a variety of devices.
U.S. Pat. No. 4,174,517 issued to Mandel, incorporated herein by reference, discloses a central system for controlling remote devices over a house's power line. A central control unit is plugged into a wall outlet for communicating over the power lines with remote units which are also plugged into wall outlets.
U.S. Pat. No. 4,200,862 issued to Campbell et al., incorporated herein by reference, discloses an appliance control system wherein a data transmitter communicates with slave units over a house's power lines by using digital address and operation signals. In Campbell, the data transmitter and various slave units are plugged into wall outlets.
U.S. Pat. No. 5,066,939 issued to Mansfield, Jr., incorporated herein by reference, discloses a circuit for communicating over a house's power lines in which extension telephones are connected to a conventional electrical wall outlet. A master station connector is plugged into a wall outlet and is also connected to the telephone line to facilitate full duplex communication between the extension telephones and the house's telephone line.
It is further known in the art to provide digital network services to a house. U.S. Pat. No. 4,332,980 issued to Reynolds et al., incorporated herein by reference, discloses a multiple service system which delivers a variety of services to a subscriber over telephone lines. The services disclosed in Reynolds include remote meter reading and load management. In Reynolds, a subscriber data subsystem is placed in the subscriber's house and communicates with peripheral devices over a subscriber data bus. The subscriber data bus is accessed via dedicated wiring and separate data service wall jacks.
U.S. Pat. No. 5,101,191 issued to MacFayden et al., incorporated herein by reference, discloses a house wiring arrangement for controlling the distribution of energy and communications within a house. MacFayden provides a gateway terminal as an interface for communicating outside the house over the public telephone network or power lines.
An article entitled “Country Road Warrior” and written by Todd Lappin, published in the August 1995 issue of WIRED on pages 46 and 50, incorporated herein by reference, discloses an electric company which provides digital network services to its customers using conventional communication technology over a coaxial cable network. The network was installed for remote meter reading and later adapted to deliver high-bandwidth data services.
None of the prior art discloses a utility meter or data port which provides an interface between a digital service network and home electronics.
In Parasekvakos, Frew, Selph, and Bonner, the electronics associated with the utility meter are directed primarily to meter reading functions.
In Mandell, Campbell, and Mansfield, communication over the power lines is directed primarily to communication with devices within the house. Also, in Mandell, Campbell, and Mansfield, a separate “master” unit must be located inside the house and plugged into a wall outlet.
In both Reynolds and MacFayden, a house must be wired with a special wiring configuration to accommodate the specific bus structures and communication methods disclosed. Reynolds and MacFayden also require some type of interface unit located inside the house. The network described by the Lappin article does not use a computer in the meter as an interface with the digital network, but rather requires installation of a special jack for connection to the network.
It is an object of the present invention to overcome the above and other disadvantages in the prior art. Specifically, it is an object of the invention to provide a data port with associated electronics to perform functions beyond meter reading, including functions such as providing an interface between a digital services network and home electronics.
It is an object of the invention to provide a digital service network interface which is not located inside the house and does not plug into a wall outlet.
It is an object of the invention to provide digital data services into a house without rewiring the house and without requiring special wiring.
It is an object of the invention to provide conventional meter capabilities in conjunction with associated electronics and broadband access to digital networks.
It is an object of the invention to provide a multifunction data port device in a secure sealed location where installation or removal requires breaking the utility's meter seal.
Yet another object of the invention is to provide a data port which provides a secure banking and Internet browsing capability.
The above and other objects of the invention are accomplished by a data port having a standard electric power meter and associated electronics within a meter enclosure and having a standard base suitable for mating with a standard meter box. The associated electronics include a computer having a network interface and a house interface.
The computer may include a video processor and/or descrambler for television services, a modem processor for data services, and a voice processor for telephone services. The computer may also include a meter interface for remote meter reading. The meter interface may be coupled to a circuit breaker box equipped with triacs or solid state switches for load management. The computer may further include a personal computer (PC) interface coupled to the other various processors and interfaces.
The network interface may be coupled to a digital service network, which communicates, for example, via satellite, wireless communication, fiber optic cables, coaxial cables, or twisted pair telephone lines. The house interface may be coupled to the house's internal wiring including the house's power lines, telephone lines and television coaxial cables. The house interface may communicate with home electronics via wireless communication through, for example, short range microwave signals such as those used by cordless telephones. The network interface may be directly coupled to the house interface and/or coupled through the various other processors and interfaces.
Additional objects and advantages of the invention will be set forth in the description, which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and obtained by means of the instrumentality and combinations particularly pointed out in the appended claims.
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate presently preferred exemplary embodiments of the invention, and, together with the general description given above and the detailed description of the preferred embodiments given below, serve to explain the principles of the invention.
According to the invention, electric company 120 provides a digital service over a network communication line 160, which may be, for example, fiber optic cable, coaxial cable, wireless, power lines or twisted pair cable. The data port 165 provides an interface between the digital service network and the internal house wiring 134. Internal house wiring 134 may include, for example, power lines, telephone lines, and television coaxial cables. An electronic interface device 150 can plug into a wall outlet 138 to access said digital service network. Device 150 may, for example, provide video, multimedia and game signals to television or monitor 142.
As previously discussed, the electric meter 110 is owned by the electric company 120 and is installed in the meter box 114 which is provided by the building owner or by the utility. The data port 165 according to the invention includes the addition of a video connection and various computer electronics and switches and in this embodiment, the data port 165 is attached by wire and/or wirelessly 164 to said meter 110. The electric meter 110 continues to measure power consumption by standard means. The addition of the data port's 165 signal processing permits the electric company 120 and/or the ISP 161 to provide, for example, both video and telephone communication in addition to electrical service.
The data port 165 according to this embodiment of the invention may also provide remote meter 110 readings and load control, simultaneously with interactive communication, and a household computer connection at very little extra cost. The use of the data port 165 to read the electric meter 110 is advantageous because the electric company can justify the costs to a regulatory agency on the basis of remote meter readings, load control, and customer billing and communication at times of power outages and other emergencies. The data port 165 according to the invention also can be quickly installed in the sealed meter box 114. The invention thus permits a regulated electric utility 120 to have an unregulated subsidiary that can deliver broadband access to digital and analog data and be in the telephone, video or multimedia business.
Further advantages may be realized because many electric companies already run fiber optic or coaxial cables or wireless connections to their major switching stations. Typically, utility companies have easements and own the utility poles. Therefore the electric company can easily extend these cables or wireless connections to each household.
The electric utility also has the option to work with a cable company to use the cable company's previously existing coaxial lines. For example, the previously-existing coaxial cable may be run directly to the data port 165 according to the invention and thereafter supplied to the house with multiple functions supplied by the data port 165. Data port 165 may be installed and attached to existing coaxial cables quickly without access to the internal wiring of the house. The utility 120 may be in a good position to negotiate with the cable company because it has the alternative of running its own coaxial cable and offering Internet and digital cable service competing directly, like the electric company in the Lappin article.
Electric company 220 supplies electrical power over external power lines 228 which are connected to standard electric power meter 280 and house's internal power lines 232. House interface 274 is also coupled to house's internal power lines 232 and the house's other internal communication wiring 236. The house interface 274 may communicate with devices such as those described in the prior art references. The house interface 274 may also transmit and receive telephone and computer signals over the internal power lines 232 and the network interface 272 may receive and transmit these signals over the network communication line 260. This configuration puts the digital service providers 261 in communication with home electronics over the network communication line 260, through the data port 270.
The electric utility 220 and/or digital service providers 261 may, for example, compete with a local telephone company by providing a telephone device adapted to communicate over the internal power line 232 or communication line 236 to the house interface 274 and through the data port's 270 network interface 272 to a digital switching service 261. Thus, the voice processor 394 shown in
In another example, said data port 270 with network interface 272 may function as a computer switch and Internet router and communication line 260 may comprise a fiber optic or coax cable or wireless. A computer switch or router operating in conjunction with connection 260 to a digital service provider 261 can receive several hundred channels of information, and broadband data transmission. House interface 274 may be in communication with a home electronic device, such as a video monitor, and may, in response to a request from the home electronic device, function to select a desired channel for transmission over the internal power lines 232 and/or other internal wiring 236 to the home electronic device. Network interface 272 with data port 270 may be further operative to descramble signals, function as a firewall, and provide billing information. Because of the ease of installing a data port 270 according to the invention, connection to a digital service provider 261 is relatively inexpensive.
The meter box 214 is typically located near a junction of the internal telephone and cable lines 236 and power lines 232, all of which belong to the house owner 230. An electric meter case 210 containing a data port 270 according to the invention, by being installed in the sealed meter box 214, puts the electric company 220 in an advantageous position to control the flow of multimedia information. Because of the advantageous location, the invention provides convenient access to the utility user's electronics.
The electric company 220 can also provide the home owner 230 a unique advantage by integrating the various functions described herein into the data port 270 in the electric meter case 210 according to the invention. Because the electric company owns and can replace the previously-existing electric meter with an electric meter 280 and data port 270 according to the invention, the invention eliminates the need for any installation on the part of the customer 230. The invention is advantageous even in new construction situations, because no additional installation is required. The invention provides a further advantage by not requiring a dedicated wall outlet or special wiring to provide access to a digital service network.
Network interface 372 provides a remote wireless transceiver device 362 to communicate via wireless transmission 361. Such communication might include transmitting and receiving signals over a selected microwave frequency channel, or the publicly owned Industrial, Science and Medical (ISM) band broadcasting. Data transmission on the selected frequency channel might also include such techniques as token ring data transmission, spread spectrum transmission, and/or packet data transmission. Alternatively, wireless transmission media might include infrared, optical, cellular, or satellite communications.
Said data port 370 provides a video processor 390, a modem processor 392, and a voice processor 394 and a meter interface 384, all of which are coupled to network interface 372, house interface 374, and router computer 398 for both receiving and transmitting their respective signals. Said data port 370 also provides a battery backup 376 to supply power to the data port with its attendant electronics and multiple interfaces 370 in the event of a power failure, and a hard disk drive 399 or alternative storage device.
Data port 370 may notify electric company 320 in the event of power failure. Likewise, the data port 370 may store customer service messages from the power company 320 on hard drive or memory storage device 399. In the case of a power outage as detected by the meter interface 384, the data port 370 could retrieve a customer service message from drive 399 and use it to telephone and reassure the customer that the utility is aware of said power outage and is working to solve the problem. Typically, the utility customer service telephone lines are overloaded at times of power problems and the recorded message should help to reduce the number of telephone calls.
Video processor 390 operated by the data port 370 is further coupled to de-scrambler 396 for providing de-scrambled video signals to house interface 374. For example, the video processor 390 may be an a commercially available MPEG-2 decoder chip, with both audio and vide decoding capability. Alternatively, multi-chip or software MPEG-2 decoders can be employed, or decoders based on other audiovisual standards, such as motion JPEG, MPEG-1, MPEG-4, H.261 or H.263 may be utilized.
The data port's 370 hard drive 399 may also be written with educational or commercial materials previously requested by the customer via messages received by processors 390, 392 & 394 at times when there is little demand for telephone usage. Such capability allows the customer fast access to materials recorded on the drive 399 without the need for high speed broadband access, in the case where such access is not available. A full feature movie or other lengthy audiovisual materials could be ordered by a consumer for delivery during off-peak hours.
House interface 374 is coupled to house's internal wiring including house's internal power lines 332, and telephone lines or communication wiring 338, and television coaxial cables 339. The house interface 374 may also communicate with home electronics via wireless communication 375. For example, cordless telephones communicate over short range microwave signals, including the IEEE standard 802.11a/b/g. The house interface 374 may utilize similar short-range wireless communication using antennas 378 and 377.
Computer-router 398 is coupled to house interface 374 and can provide personal computer functions to users in house 330. Personal computer peripherals which require user access, such as floppy disk drives, audio speakers, and CD ROM drives, may be provided inside the house 330 and communicate with the data port's computer-router 398 through the house interface 374. Thus, the data port 370 according to the invention may be used as an Internet router 398, incorporating all the functions of a personal computer configured for Internet browsing.
Electric company 320 provides electrical power service over external power lines 328. External power lines 328 enter the meter box (not shown) 134 to which meter 380 is sealed and then into the house 330 via power lines 332 to circuit breaker box 388. Meter interface 384 is electrically connected to the power meter 380 and it is electrically connected via power lines 332 to circuit breaker box 388. Circuit breaker box 388 passes electrical power service to house over the house's internal power lines (not shown) 134. The embodiment shown in
Alternatively, the device may be employed to change thermostat settings for air conditioning, heat and hot water functions in the house 330 as a function of changes in the cost and/or availability of electric power. In order to effect such changes, the utility would transmit to the device the current cost of power, which would then be compared to predetermined thresholds set by the home owner and change the temperature settings for the water heater and air conditioner. The house owner can thus select a permitted range of thermostat changes for their electrical services based on the cost of power.
In addition to reduction in costs for meter reading, the third embodiment of the data port 370 may also detect tampering or attempts at bypassing the meter 380. Likewise, a global positioning satellite may be employed to monitor the position of the meter via wireless transmission device 362 to detect movement of the device and the location of the device, in the event of a disaster or tampering.
The data port 370 coupled to electric meter 380 according to the invention can also notify the utility when there is a power outage. Another example is advantageous billing arrangements. If there was a problem with the customer's payments, the electric company 320 could instruct the data port 370 to notify the customer through, for example, a message on the customer's television 142 or by email over the Internet or any digital network as the invention prescribes.
Regarding load management, the use of triacs or other solid state switches (not shown) in meter 380 or circuit breaker box 388 enables the electric company 320 in communication with the data port 370 to selectively turn on and off the power remotely to specific circuits. For example, the electric company 320 might turn off hot water heater circuits during excess power demands. In another example, the triacs in communication with the data port 370 and the electric company 320 can be used to reduce the voltage if the power company has excess power demands. Triacs or other remotely controlled switches in the meter box 114 (not shown) coupled with the data port 370 could also be used to remotely shut off power if there is evidence of meter tampering, unpaid power bills or a change in the account, such as a request for disconnect made by the house owner through the data port 370, or communicated to said data port by the electric company 320 and/or the house owner.
The data port 370 coupled to the electric meter 380 according to the invention also provides advantages for the customer's own energy management. The customer can use the data port 370 coupled to the electric meter 380 according to the invention to change the thermostat settings for air conditioning and the hot water heater and to control the use and operation of appliances. This system will permit the customer to enjoy reduced rates by, for example, running the dishwasher and hot water heater at the times of lowest power demands and reducing the air conditioning load at times of peak demand. The interaction of the TV 142 and internal power lines advantageously permits the power user to control their power use with the TV as a potential monitor or with the house owner's computer peripherals and the data port 370. For example, the data port 370 according to the invention can be programmed to give different customers an individual choice of lower power rates by controlling the timing of different loads or higher rates with unrestricted use of power.
The data port 370 and its multiple interfaces 372,374,384 coupled to electric meter 380 according to the invention also advantageously provides each household with the functional equivalent of a personal computer, which can potentially use a TV 142 as a monitor, and be connected to the house owner's other computers and peripheral electronic devices and microprocessors, forming a home network. The electric company 320 or the ISP 360 may supply or rent software for the personal computer 398 over the said digital service network.
For example, the electric company 320 might provide a “free” service for school children to use said data port and Internet access for their homework. This has the advantage of improving the public relations with utility customers and the state regulatory commissions as well as getting children used to using the software made available by the electric company 320 and/or the ISP 360. The data port 370 according to the invention might be used by the house owner to also utilize the computer-router 398 in said data port, coupled to the meter 380 to provide access to the Internet and for conducting secure financial transactions, such as described below in
A regulated utility, like an electric company 320, can justify the costs of the data port 370 coupled to the electric meter 380 according to the invention because it will reduce the costs to read meters, provide better communication between the utility and its customers and it will provide significant help in power management. The unregulated portion of the electric company 320, which could also be an ISP 360, can obtain revenues from electronic communications. Recent legislation has reduced regulation in communications and this opens the field for the electric company 320, which is already connected to every house. The data port 370 coupled to the electric meter 380 according to the invention will enable the electric company to be competition for both the telephone and television cable companies and provides a strong incentive for these companies to work with the electric company 320 by supplying a digital service network over existing telephone and television lines, by fiber optics or wirelessly, or any combination thereof according to the embodiment of the invention described in
Electric meter-data port 410 has a meter enclosure 412, which encloses standard electric power meter 480 and associated electronics of the data port 470. Meter enclosure 412 forms a seal with meter seal ring 418 to provide protection from the elements and is mated with standard meter box 414 and by the seal 418 is sealed to the meter box 414. External power lines or conduit 428 enter the sealed meter box 414 from the top (or any angle or direction) and power is supplied to a house 330 through a power conduit 433 also coupled and/or connected to the data port 470 which said conduit is shown exiting the meter box 414 from the side.
Associated electronics 470 are coupled to communication line 460 through a cable 465. Electric meter enclosure 412 provides a stress relief 467 for cable 465. Cable 465 is coupled to communication line 460 at connection point 463, and to the data port 470. Signals are communicated in the house over internal cable 436 or by power lines 332 in this embodiment.
According to the fourth embodiment, communication line 460 comprises, for example, a coaxial cable, a fiber optic cable, power line, wireless or a twisted pair telephone line. In the case of a coaxial cable, connection point 463 may be a simple coaxial “T” connection. Connection point 463 may otherwise be a “splice” type connection wherein signals on communication line 460 are passed directly onto internal cable 436 in addition to being processed by the data port and its associated electronics 470 over cable 465.
For example, communication line 460 may deliver conventional television signals to the house, some of which are scrambled or in digital format. The conventional signals could be delivered directly to the house for reception on a conventional TV. Concurrently, via a “T” connection, associated electronics in the data port 370 may process the scrambled television signals and deliver de-scrambled television signals over the house's internal power lines for reception by a remote device 150 plugged into an electrical wall outlet. The remote device would put the de-scrambled signals back on conventional television coaxial cable or conventional video and audio cables 339 for reception on the TV 142. Alternatively, the associated video processor 390 electronics could convert digital TV signals to analog signals and/or may shift and superimpose the de-scrambled television signal onto internal cable 339 for reception on the conventional analog TV 142.
The data port 370 according to the invention can provide numerous advantageous applications to the user. For example, the user can request information regarding the user's utility usage and bill. The user may utilize the data port 370 according to the invention for Internet banking or to pay the utility bill and other bills via credit card or other payment arrangements.
Another example is information access. The data port 370 according to the invention could provide a virtual personal computer for the user that can be interfaced to the user's home electronics and appliances. The personal computer connection feature may provide access to various interactive computer services supplied by the utility 320 or the ISP 360, or both. For example, the user can utilize the data port and its associated electronics 370 according to the invention to access the Internet and other information sources. The user could use their home television set 142 as a display or monitor. The electric company 320 or the ISP 360 or both may also provide computer software and games for use with the virtual personal computer function of the data port 370, 470 and its associated electronics and interfaces.
Both the electric company 320 and the user could use the multifunction data port 370 according to the invention advantageously for load management. The electric company 320 could, for example, suspend electric service to non-essential circuits, such as hot water heaters, during peak demand times. The user could, for example, arrange to have the dishwasher run during lower rate hours. The electric company 320 could also use the data port and its associated electronics 370 according to the invention for remote meter reading and also for detection of tampering by, for example, determining unusual changes in power usage.
The data port 370 according to the invention can also detect power outages and other problems with the electric company's distribution system. The data port's computer-router 398 may be programmed to calculate the harmonic distortion in the power line using fast Fourier transform analysis. Providing this calculation of harmonics to the power company 320 via network interface 362 can enable the said company to either correct the power factor or harmonic noise or, when appropriate, to charge higher fees when the home owner or power user is creating excessive electrical noise or power factor.
Alternatively, the data port 370 device may be employed to remotely change thermostat settings for air conditioning, heat and hot water functions in the house 330 as a function of changes in the cost and/or availability of electric power; this may be accomplished by the house owner or the utility or both, though the use of the data port and its associated electronics 370. Power costs have recently gone as high as $500 to $1,000 per kilowatt-hour at times of reduced generation capacity. In order to effect such changes, the utility 320 would transmit to the data port device 370 the current cost of power, which would then be compared to predetermined thresholds set by the home owner on the computer router 398 of the data port 370. The amount of the change in thermostat settings could be set as a function of the current cost of a kilowatt-hour. The house owner is able to choose different ranges of thermostat settings at times of reduced generation capacity depending on the cost of electrical power. Both the utility user 330 and the utility company 320 can change thermostatic settings in this embodiment of the invention remotely over the Internet from any location utilizing the features of the data port 370. Changing settings on thermostats is a much better way for the utility to shed load than cutting power to whole regions of the city.
The data port 370 according to the invention provides a further advantage of being able to monitor and collect data on the television 142 viewing habits of the user. Safeguards must insure that this information is only available if the homeowner authorizes it. Likewise, the data port could be used as the means for voting or census taking. Such information can be collected at the home 330 and communicated over the communication network 362,364,366, 368. For example, viewing habit information may be collected by the video processor 390 of the data port 370 and stored on the hard disk or other memory device 399 of the data port 370 by the data port's router-computer 398, and transmitted to the electric company 320 upon request. Such information is useful to determine the size of the viewing audience for various different television programs. Likewise, voting, census or other information could be collected in the house 330 using a television remote control or other input device coupled to the data port as a sealed secure terminal 623.
The data port 370 according to the invention could be used for interactive instructional and job training programs in the home. An instructional program could be viewed on the user's television set and the user could, for example, use a remote control device coupled to the data port 370 to respond to multiple choice questions posed by the instructional program.
Other advantages of the data port 370 include the ability for the electric company 320 to provide video signals, such as pay-per-view programs, to the user. The signals may be scrambled at the point of distribution and de-scrambled 396 by the data port 370 according to the invention. The electric company 320 may also provide connection to various local and long distance telephone services and the ISP 360 through the data port 370 according to the invention.
A particularly advantageous use of the data port 370, 470 according to the invention includes monitoring movement and/or a personal medical alert device worn by a user inside the home. Such a device may, for example, transmit medical data on a periodic basis and be relayed to a physician through the data port 370, 470 according to the invention. For example, the device 370 could transmit information by way of a wireless connection 361,362 to the utility company 320 or digital service provider 360 via the computer-router 398. Alternatively, said device may be activated by the user to alert emergency medical services through the data port 370, 470 according to the invention. A similar advantage can be achieved to monitor movements of a user restricted to their homes by, for example, a court order when said user is wearing a wireless homing and/or tracking device coupled to the data port 370, 470. Computer 398 in multifunction data port 370 may include global position software (GPS) for detecting a satellite identified location of the personal medical alert device or other such other tracking device using, for example, network wireless transmission 362 which includes GPS satellite communications. Multifunction data port 370 may also be configured to detect security breaches in the seal 418 of said data port with motion sensors (not shown).
As noted above, the data port 370 according to the invention can transmit and or receive information from digital and analog networks directly over the power lines 128. Any of the several well-known techniques for using power lines to transmit digital or analog information into the home 330 may be employed. For example, Dr. Sanderson has described a system for distribution of broad band multi-media services over the high-voltage cables of a power distribution network (U.S. Pat. No. 6,040,759), the disclosure of which is incorporated herein, and this 759 patent includes other references to power line carrier technology (PLC) also known as broadband over power line (BPL).

In addition, bank 621 has the option 635 to check if the vendor is not trustworthy, e.g., because it is a suspect company or the option 636 to check if the vendor is not a domestic business subject to US laws 630, in which event additional purchase authorization requirements may be imposed 632. Options 635 and 636 may be exercised sequentially. First exercising option 635, bank 621 may find that the vendor is untrustworthy (untrustworthy=YES), then bank 621 may refuse authorization (641). If the vendor is trustworthy (untrustworthy=NO), bank 621 may then exercise option 636 to check if the vendor is or is not a domestic business subject to US laws. If vendor 630 is subject to US domestic laws, bank 621 may promptly guarantee payment to the vendor (631). If vendor 630 is not subject to US domestic laws, bank 621 may require proof that vendor 630 has shipped the goods to the purchaser before guaranteeing payment (632).
Only when all safeties are met will the bank 621 guarantee payment to the vendor 630 and the transaction is consummated 631. Each secure purchase or secure transaction by the purchaser house owner at data port interface 620 rate will generate a different encrypted key or encryption algorithm for each transaction or purchase. In this way, the purchaser 620 is offered additional consumer protection to prevent transactions initiated by a third party which may have gained unauthorized access to his or her credit card information or in dealings with potentially troublesome vendors 635.
