## Background
CROSS-REFERENCE TO RELATED APPLICATION(S)
This application is a continuation-in-part of U.S. patent application Ser. No. 14/083,119 filed on Nov. 18, 2013, entitled “Digital Color Clock”.


FIELD OF THE INVENTION
The present invention relates to the use of color output to represent numerical digits in applications involving dynamic digital displays. One embodiment involves use of such color representations in a digital clock with a panel displaying six Color Outputs, each of which displays a unique color corresponding to, in the embodiment of a clock, each digit of hours, minutes and seconds. In other embodiments, dynamic numeric information such as date, temperature, humidity and/or barometric pressure, can be displayed, where each of ten specific colors represents a single decimal digit, namely, zero through nine (0-9).
BACKGROUND OF THE INVENTION
Man has been using devices to keep time from at least as early as the 16th century B.C. These earliest devices were simple water clocks with the first mechanical clocks appearing in 13th century Europe. The first mechanical clocks did not have a visual indicator of the time, but instead signaled the time audibly via bells. Over the centuries, a visual indicator was added in the form of a clock face, which eventually evolved into the traditional twelve-hour face used on many analog clocks. With advancements in technology, digital clocks that display the time in readable digits became prevalent in the 1960s and have steadily been replacing analog clocks. In fact, most individuals today are familiar with digital clocks, and many find them much easier to use than analog clocks.
Common among most clocks, either digital or analog, is their reliance on either Roman or Arabic numbers to indicate the time. Some clocks, such as the one described in U.S. Pat. No. 5,228,013, have abandoned the use of Roman or Arabic numbers. These clocks instead use a complex pattern of flashing lights integrated in a piece of art. While this design is creative, it is not easily identifiable to an uninitiated observer as a clock. Furthermore, even if an individual is aware that the device is a clock and is trained to use it, he/she must still wait for the clock to go through its complex pattern of flashing lights, to discern the time. A clock that does not use Roman and Arabic numbers, but still displays the time in a customary 12-hour or 24-hour format, would be desirable to provide entertainment along with a useful display of the time of day. One such customary format is the one commonly used with digital clocks, namely, [h1h2]: [m1m2]·[s1s2], where:

    
    
        h1=tens digits of the hour being displayed, in units of 0 through 2;
        h2=ones digits of the hour being displayed, in units of 0 through 9;
        m1=tens digits of the minutes being displayed, in units of 0 through 5;
        m2=ones digits of the minutes being displayed, in units of 0 through 9;
        s1=tens digits of the seconds being displayed, in units of 0 through 5; and
        s2=ones digits of the seconds being displayed, in units of 0 through 9.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENT(S)
FIGS. 1, 2 and 3 illustrate various examples of a digital color clock.
FIG. 1 is a basic unit of a digital color clock 10. The main panel of housing 20 includes six Color Outputs for the tens digits of the hour 12, the ones digits of the hour 14, tens digits of the minute 16, the ones digits of the minute 18, tens digits of the second 26, and the ones of the second 28. The display uses a colon 22a, 22b and a period 24 for the unit separators.
For a 12-hour clock, the Color Output for the tens digits of the hour 12 shows the first two colors in the code, corresponding to 0 and 1. Likewise, the Color Outputs for the tens digits of minute 16 and the tens digits of the second 26 show the first six colors in the code, corresponding to 0 through 5. The rest of the Color Outputs show all ten colors in the code, corresponding to 0 through 9.
For a 24-hour clock, the Color Output for the tens digits of the hour 12 shows the first three colors in the code, corresponding to 0, 1 and 2. The Color Outputs for the minutes and seconds would remain the same as those of the 12-hour clock described above.
The basic unit includes an optional LCD panel 34 and a collection of buttons 32, which can be used to set the time or an alarm, among other functions.
FIG. 2 is digital color clock utilizing various shapes for the Color Outputs 110. Its main panel 120 includes six Color Outputs for the tens digits of the hour 112, the ones digits of the hour 114, tens digits of the minute 116, the ones digits of the minute 118, tens digits of the second 126, and the ones of the second 128. It does not contain a unit separator but does contain a collection of buttons 132, which can be used to set the time or an alarm, among other functions
FIG. 3 is an advanced digital color clock 210 with a front panel 220 utilizing six Color Outputs for the tens digits of the hour 212, the ones digits of the hour 214, tens digits of the minute 216, the ones digits of the minute 218, tens digits of the second 226, and the ones of the second 228.
The advanced digital color clock 210 also contains three Color Outputs for the temperature, one for the tens digit of the temperature 242, one for the ones digits of temperature 244, and one for the tenths digits of temperature 246. This embodiment employing three Color Outputs as described would be suited to indoor temperature readings in Fahrenheit units. If the outside temperature were to be displayed, then the digital color clock would contain four Color Outputs, one for the hundreds digit of the temperature, one for the tens digit of the temperature, one for the ones digits of temperature, and one for the tenths digits of temperature. There would also be a Color Output to display a minus sign when the outside temperature is below zero.
The advanced digital color clock 210 further contains three Color Outputs for the humidity. One for the tens digits of the humidity 248, one for the ones digits of humidity 250, and one for the tenths digit of humidity 252.
In addition, FIG. 3 contains two decimal points, namely, decimal point 254 located between the ones digit of the temperature and the tenths digit of the temperature, and decimal point 256 located between the ones digit of the humidity and the tenths digit of the humidity. FIG. 3 also contains two mathematical symbols, namely, degree symbol 258 for the three preceding Color Outputs for temperature and percentage symbol 260 for the three preceding Color Outputs for humidity.
Finally FIG. 3 illustrates an optional LCD panel 234 and a collection of buttons 232, which can be used to set the time or an alarm, among other functions.
Turning to FIG. 4, an 8-bit microcontroller 326 running custom firmware code performs time-keeping functions, reading of buttons 334 for setting time and display modes, monitoring of ambient lighting conditions from a front light sensor 314 and a top or back light sensor 316 for automatic color and brightness adjustment, and other optional functions such as reading a temperature and/or humidity sensor 312, receiving information from a weather receiver 318 configured to receiver data from a remote weather station or displaying data on an optional LCD panel 322. The microprocessor produces a multiplexed pulse-width-modulated output, which feeds power output 336 for driving 40 red-green-blue light-emitting diodes (RGB LEDs) and 8 single-color LEDs 338, each capable of displaying 42-bit resolution (over 4 trillion colors). This robust color-depth capability allows the device to display its ten-digit colors over a large range of ambient lighting conditions. A 16-channel constant-current PWM LED driver 340, is used to adjust the LED color. Additional drivers 342, may be utilized to increase the numbers of LEDs being used, although this would decrease the number of shades that could be used by any single LED.
FIG. 5 shows a digital color clock embodiment with its Color Outputs displaying a time of day of 12:34.56. An optional LED or LCD panel is located between the Color Outputs displaying the 56 seconds of the time of day and the labels for the buttons at the top edge of the clock's front face. The optional LED/LCD panel could be used as a standard numeric digital time display or for advanced features, such as the setting of alarm(s) or color code customization.
As an option, additional outputs for displaying other temporal information, such as year, month, day, temperature, barometric pressure and humidity can also be provided. Additional LED outputs can also support LEDs for displaying the colon symbol traditionally used to separate hours, minutes and seconds. Additional LEDs can also be used to illuminate the case or frame for the clock.
The clock can also act as a slave to another host processor 344. In this embodiment, the clock would simply display the numbers received by host processor 344. For example, the host processor might be running a program that counts down until a child's birthday. In this embodiment, the clock would display the digits being fed to it from the host processor as Color Outputs.
Color and brightness uniformity of each Color Output are important for correct, unambiguous identification of the 10 colors. Several techniques are employed to evenly illuminate each Color Output. Each RGB LED or LCD (which can be a “bank” of many individual red, green and blue LEDs or LCDs) illuminates a Color Output from the side or rear, tailored for high contrast and uniform light output and mixing of the individual red, green and blue LEDs or LCDs.
Techniques similar to those employed in edge-lit backlights for high-quality color LCD panels in television and computer monitors can also be employed in the present digital color clock.
The present digital color clock can adapt to the changing lighting conditions of the environment in which the device resides (to which the user's eyes also adjust with respect to brightness and white-balance), thus making the Color Outputs accurately readable in a wide range of ambient conditions. Two light sensors (typically digital RGB ambient light sensors or simply analog phototransistors with color filters) can be incorporated to scale the brightness and hue of the ten digital colors generated by the LEDs or LCDs.
An algorithm in the microcontroller's firmware can slightly adjust the LED color code's overall hue to adjust for varying environmental white balance by integrating light sensor data. The algorithm can incorporate digital low-pass filters so these adjustments to brightness and hue occur with a similar speed as the human eye, making these changes transparent to the user.
To increase its functionality, the present digital color clock can contain an infrared LED and receiver 332 for remote control use, an alarm amplifier and speaker 330, a microphone for automatic adjustment of alarm volume 328, a weather receiver configured to receive data from a weather station 318, and/or an atomic clock data radio receiver 324.
In one embodiment, the present digital color clock contains a sequence of Light Color Outputs that can display multiple colors depending on the inputs to the LED's through the circuit hardware and firmware that controls the LED sequence for all LED's. In one example, the circuit hardware and firmware controls the LED output colors in a six sequential LED display including a time of day made visible in hours, minutes, and seconds. Time can be displayed in 12 hour or 24 hour outputs. Optional outputs and applications include but are not limited to temporal information such as year, month, day, temperature and humidity.
Instead of the traditional format of displaying standard numerals on a 7-segment or graphic dot-matrix display (or digital representation of a standard analog clock), the present clock has a panel which displays its digits, 0-9, as specific, unique colors. In one embodiment, the ten specific color outputs are as follows:











Digit
Color







0
Black


1
Brown


2
Red


3
Orange


4
Yellow


5
Green


6
Blue


7
Purple


8
Gray


9
White









In the foregoing embodiment, the colors correspond to the standard color codes for resistors and other electronic components, which were developed in the early 1920s by the Radio Manufacturers Association. The current international standard is IEC 60062 published by International Electrotechnical Commission. (See https://en.wikipedia.org/wiki/Electronic_color_code, accessed on Oct. 4, 2015.)
Each color displayed represents, in accordance with a standard or custom color code, the specific digits of the hour, minutes and seconds of the current clock time. Upon learning the color code, a user can tell the time. The Color Outputs need not be any specific size or shape, though specific tailoring can be of some advantage to visibility across a distance. Nor need the Color Outputs be the same size or shape of each other. For example, the Color Outputs representing the hours and minutes could be large circles, while the Color Outputs representing the seconds could be small squares.
In one example, the clock uses six Color Outputs to report the time. Two Color Outputs are used to represent hours, two for minutes, and two for seconds.
In addition to the six horizontally-arranged Color Outputs, the panel can contain unit separators. The most common unit separators would be a colon between the hours and minutes Color Outputs and a period between the minutes and seconds Color Outputs. The unit separators may also be illuminated but preferably not in a color used by the Color Outputs. The separators act as additional indicators of the clock's function and make it easier to read the time.
In another embodiment, the unit separators may be other symbols. These symbols make it harder to tell that the device is a clock, but still serve as a reference point for one who is aware they are looking at a clock and make it easier to read the time displayed by the Color Outputs.
Both the separators and the Color Outputs can be illuminated using red/green/blue light-emitting diodes. In one embodiment, the Color Outputs and separators are surrounded by other unchanging light-emitting diodes.
The digital color clock can also include an alarm, temperature, humidity and optical sensors, atomic clock data radio receiver, and an infrared receiver for remote control operation. Preferably, the digital color clock will also include ambient light sensors to facilitate accurate reproduction of the colors involved.
Replacing digits with colors can help persons with learning disabilities to tell time by reading ten unique colors corresponding to ten unique digits. It is also useful for those with vision problems, as in certain situations it is easier to differentiate between the Color Outputs than attempt to read actual numbers. A flicker or sparkle effect could be applied to certain colors (instead of using static colors for every digit) to make the device equally useful by the partially colorblind.
In one embodiment learning the color code is fairly simple and can be accomplished by watching the repeating pattern of the Color Outputs, specifically those related to seconds.
The logic required by a user to decipher the code and timing of the associated learning curves could be employed to measure the acuity and capabilities of the human brain, making the clock useful in Intelligence Quotient measurement or for evaluating mental health conditions.
To further aid in reading the clock, a color code decoding table or “cheat sheet” can scroll across on optional LCD screen. In one embodiment the cheat sheet could scroll the code, “0=Black, 1=Brown, 2=Red, 3=Orange . . . . ” In another embodiment, the cheat sheet could actually display the time in digital format, making it easier for the user to decipher the code.
The use of Color Outputs in place of Arabic or Roman numerals is not limited to a physical clock. The Color Outputs may also be used in a clock on a smartphone, tablet, computer, and the like. The color output could also be used as an alternative in other common numeric display devices such as calculators, alarm panels and multi-meters that measure current, voltage and resistance.
In the present digital color clock, the depth of color of each Color Output, which can display one of a multitude of colors, can be adjusted to the environment in which the clock is displayed. In this regard, the hues of the Color Outputs can be modified based upon the ambient background lighting and colors present in the environment surrounding the clock. For example, front and back light sensors can be employed to measure the brightness of the surrounding environment and provide signals to the processor to dim and brighten the Color Outputs as desired.
The present digital color clock has been shown as implemented in a stand-alone unit (see FIG. 3). The clock can also be implemented on the display of most any computer devices, such as the screen of a smart device, such as a tablet or watch, the screen of a laptop computer, or the monitor of a desktop computer.
The present digital clock can be implemented in embodiments other than a typical horizontally arranged digital clock display. For example, the Color Outputs can be interspersed in portions of artwork, such as that shown in FIG. 6, such that the Color Outputs in those portions change as the hours, minutes and seconds of time progress. Persons observing the artwork will be challenged to discern the significance of each of the changing Color Outputs, eventually recognizing how to tell time from the Color Outputs interspersed in the artwork.
While particular elements, embodiments and applications of the present invention have been shown and described, it will be understood that the invention is not limited thereto since modifications can be made without departing from the scope of the present disclosure, particularly in light of the foregoing teachings.
