MIRROR WITH DIGITAL CLOCK READOUT
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a mirror with built-in digital clock readout for use as both a functional and decorative device in the home and/or business. The mirror with built-in time readout has particular utility in simultaneously providing the time of day while looking in the mirror.
2. Description of the Prior Art
There are occasions when knowing the time while looking in a mirror is important. For example, when shaving or putting on makeup in preparation for keeping a scheduled event, it is important to know the time. In general, people look in the mirror every day and check the time several times every day. In many cases it would be convenient to perform these tasks simultaneously.
The use of time devices in combination with mirrors is known in the prior art. For example, U.S. Pat. No. 4,588,267 to Pastore discloses a combination rear view mirror and digital clock. However, the Pastore '267 patent is different in structure from that of the present invention, which is primarily intended as both a functional and attractive device for use in the home or business.
Similarly, U.S. Pat. No. 4,202,607 to Washizuka et al. discloses a mirror with information display that adds a time element to a mirror, which in one embodiment uses a reflective liquid crystal display device so that when the clock is turned off the clock area reflects as a normal mirror. However, the Washizuka '607 patent is different in structure from that of the present invention.
Also, U.S. Pat. No. 2,132,476 to Holm discloses a combination mirror and conventional motor driven analog clock with rotating hour and minute hands. However, the Holm '476 patent is different in structure from the present invention, which has a digital clock and no moving parts.
Lastly, U.S. Pat. No. 1,909,362 to Keith, U.S. Pat. No. 4,988,140 to Van Order, D423,944 to Chan, and D404,032 to Lee disclose apparatus that may be of general interest and pertinent to the construction and design of the present invention. The Keith '362 patent discloses a combination rear view mirror and memorandum device. The Van Order '140 patent discloses a visor with an electrically controlled vanity mirror cover for providing light in low illumination environments. Finally, the Chan '944 patent discloses the design for a clock and Lee '032 patent discloses the design of a clock radio with liquid crystal display. However, none of these patents disclosures have the structure of the present invention.
While the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a mirror with built-in digital clock readout for use as both a functional and decorative device in the home and/or business.
Therefore, a need exists for a new and improved mirror with built-in digital clock readout that can be used simultaneously as both a mirror and clock. The combination mirror and clock can be further used as an attractive item of display in the home or business. In this respect, the mirror with built-in digital clock readout according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of simultaneously providing the functions of a mirror and a clock.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of mirrors and clock combinations now present
5 in the prior art, the present invention provides an improved mirror with digital clock readout, and overcomes the abovementioned disadvantages and drawbacks of the prior art. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide
10 a new and improved mirror with digital clock readout that has all the advantages of the prior art mentioned heretofore and many novel features that result in a mirror and clock combination device that is not anticipated, rendered obvious, suggested, or even implied by the prior art, either alone or
15 in any combination thereof.
The mirror with digital clock readout of the present invention is comprised of a typical wall mirror combined with digital clock for reading time. To attain this, the clock, which is mounted behind the mirror, has a plurality of
20 display devices for reading hours and minutes, aligned with apertures in a black template and reflective surface of the mirror. These display devices can be light emitting diodes, liquid crystal devices, electro-luminescent displays, illuminated apertures, or other type display technology. This
25 combinational apparatus will allow a person to look in the mirror and determine the time simultaneously.
The digital clock can be powered either by battery or from a 110-volt power source. As a product, the combinational mirror and clock can be decorative to brighten up a room.
30 The digital clock display can have various appearances depending on the placement of the hour and minute display devices. In addition to the numeric clock display devices, alphanumeric devices can also be added for displaying various messages. The apparatus can be used by consumers
35 and commercial establishments in a multitude of colors, shapes, styles, patterns, sizes, and designs.
In a first example, the one-to-twelve hour digits are placed in vertical lines along each edge of the mirror with the zero-to-sixty minutes being readout in a two-digit window
40 placed conveniently on the face of the mirror.
Secondly, the one-to-twelve hour digits are placed in a more standard circular clock arrangement with the zero-tosixty minutes still being readout in a two-digit window placed conveniently on the face of the mirror.
45 Thirdly, the one-to-twelve hour digits are placed in a more standard circular clock arrangement with the sixty minutes being displayed in a circular arrangement of backlighted segments (apertures) located just inside the hour digits, thereby looking much like a familiar clock.
50 There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.
55 There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims attached.
Numerous objects, features and advantages of the present invention will be readily apparent to those of ordinary skill
60 in the art upon a reading of the following detailed description of presently preferred, but nonetheless illustrative, embodiments of the present invention when taken in conjunction with the accompanying drawings. In this respect, before explaining the current embodiment of the invention

DESCRIPTION OF THE PREFERRED
Referring now to the drawings, and particularly to FIGS. 1-8, a preferred and second embodiment of the mirror with digital clock readout of the present invention is shown and generally designated by the reference numerals 10 and 50,
In FIG. 1, a new and improved assembly for the mirror with digital clock readout 10 of the present invention is illustrated and will be described. More particularly, the
25 assembly 10 has a two-sided printed circuit board 12 with control and driver integrated circuits 14 mounted on the backside and digital display devices 16 mounted on the front side. A black template 18, which is the size of the mirror 24 and having apertures 20,22 (small windows) cut to align
30 with the display devices 16, is aligned and attached to the back side (side with reflective film) of the two-way mirror 24. This template 18 provides, with its apertures being mounted to the two-way mirror on the reflective film side, an exposed surface for the digital reading out of alphanumeric
35 digits and numbers. A circuit board 12, with matching displays 16 aligned with the template/mirror apertures, completes the assembly. Any number of digital display chips can be used to implement the clock, including light emitting diodes, liquid crystal devices, electro-luminescent displays,
40 and illuminated apertures.
FIG. 2 is a front view of the combination mirror and digital display for one version of the preferred embodiment of the present invention. In this embodiment, the hour digits
45 20 are arranged in two vertical columns along the sides of the mirror 24. This requires at least nine single-digit display chips for the numerals 1-9 and three double-digit display chips for the numerals 10-12. Minute digits 22 are readout in a separate window conveniently located on the mirror 24
50 surface. Minutes readout will require at least a double-digit display chip for the numerals 0-59, and a three-digit display if a colon (:) is included. Also, a multi-character alphanumeric display 26 can be included for displaying messages or other signage. Optionally, messages, advertisements, graphi
55 cal images could be painted on the surface of the mirror. FIG. 3 is a perspective view of an alternative picture frame-like circuit board 28 for use in the combination mirror and digital display of the present invention. Here, the circuit
g0 board 28 only covers the area where the display chips are located. This printed circuit board arrangement would work well with the embodiment of FIG. 2, since all the display readouts are located on the perimeter of the mirror. In this case, smaller circuits boards could be used and connected at
65 the corners by inside 30 and outside 32 bracket means, assuming that the assembly cost are less the reduced circuit board cost.
FIG. 4 is a drawing showing a second build-up of the mirror assembly with digital clock readout in the preferred embodiment in accordance with the principles of the present invention using multiple, smaller printed circuit boards. Here, at least thirteen small display chip circuit boards 5 36,38, along with a somewhat larger control circuit board 40 are mounted behind the mirror 34 to provide the digital clock.
FIG. 5 is a front view of the combination mirror and digital display of FIG. 4. In the case the hour digits 36 are 10 arranged in a more-or-less standard circular clock configuration and the minutes are readout sequentially from 0-59 in a separate window 38. Control buttons 42 (switches) are used to set the clock time and/or modes. The digital clock is powered by means of a battery 44 or an optional DC power 15 supply that plugs into a 110-volt outlet.
FIG. 6 is an example showing a schematic diagram 46 of an electronic circuit for controlling the digital clock in the preferred embodiment of the present invention. This is just one of many circuits that can be used with the clock. The 20 circuitry can be fabricated using any number of available or custom integrated circuits, for example programmable logic arrays, microprocessors, display drivers, and applications specific integrated circuits.
FIG. 7 is a front view of a combination mirror and digital 25 display for a second embodiment 50 of the present invention where minutes are readout by sequentially back lighting a series of segments. Here, the hour digits 54 are arranged in a circular standard clock-like configuration on the surface of the mirror 52. In use of telling-time, all numbers 54 are lit 30 with one of them being deferent from the others to signify that this is the designated hour of time. However, the minute digits 56 are arranged circularly just inside the hour digits 54, also in a standard clock-like configuration. In this case, while one of the hour digits 54 indicates the hour, the minute 35 segments 56 sequentially indicate the minute within the displayed hour, thereby providing a display that can quickly be read.
Finally, FIG. 8 is a schematic diagram 58 showing one example of a 60-output demultiplexer circuit 60 used to 40 sequentially drive the minute light segments in the second embodiment of the present invention described in FIG. 7. This circuit might typically be provided as an application specific integrated circuit (ASIC).
While a preferred and second embodiment of the mirror 45 with digital clock has been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. With respect to the above description then, it is to be realized that the optimum dimensional relationships for 50 the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the speci- 55 fication are intended to be encompassed by the present invention. For example, various numbers and types of display chips can be used to provide the digital readout. Also, the display chips can be arranged in various configurations to provide many unique clocks embedded in a mirror. 60
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and 65 accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
