This application claims the benefit of U.S. Provisional Application No.: 60/664,148 filed Mar. 22, 2005 and incorporates the same by reference.


FIELD OF THE INVENTION
The invention relates to a clock for displaying time and producing visual patterns when at least two of the hour, minute, and second indicators cross one another.
The invention further relates to methods of displaying time.
BACKGROUND AND PRIOR ART
Means for displaying time, such as clocks, watches and the like, are well known. From the ancient sundial to modern digital clocks, many different configurations and ways of displaying time have been contemplated throughout history.
There are two general forms of clocks. One is the more traditional analog clock in which the hour, minute, and second hands rotate about a center. An example of this form of clock is the clock on Big Ben in London, England. The other is the more modern digital clock which numerically displays the hours, minutes, and seconds. Typically, this form of clock displays a six-digit representation of time, which is generally displayed by six seven-segment displays.
Aside from the aesthetic design of the clock face or the housing, conventional clocks only display time. Furthermore, conventional clocks generally do not provide any visually stimulating and exciting displays to attract people to view the clock at certain times.
SUMMARY OF THE INVENTION
An object of the invention is to provide a device for indicating time (hereafter referred to as a clock) which displays a unique visual pattern.
Another object of the invention is to make the visual pattern easily recognizable as representing actual time of day or night.
A further object of the invention is to produce special visual features when certain time periods take place.
A feature of the invention is to produce such a visual feature when at least two of the hour, minute, and second indicators coincide with one another.
A further feature of the invention is to produce a special visual feature when all three of the hour, minute, and second indicators coincide.
In a preferred embodiment, the clock displays a flash of light when at least two of the hour, minute, and second indicators cross one another.
The above and further objects of the invention are achieved by a clock which comprises a rectangular screen with graduations along its length representing time periods and a plurality of progressively movable light bands traveling along the screen to indicate hours, minutes, and seconds of time respectively.
In another preferred embodiment, the light bands are of different color.
In another preferred embodiment, the light bands are of different size.
In accordance with the invention, when one light band overlaps another, a plurality of light flashes are produced.
In further accordance with the invention, the light flashes travel in opposite directions on the screen to the ends thereof.
In a preferred embodiment, when all three light bands overlap, an even more elaborate display of light flashes is produced.
In a preferred embodiment, a sound display accompanies the light flashes.
In accordance with another aspect of the invention, a method for displaying time is provided which comprises providing a clock face having successive graduations thereon representing hours, minutes, and seconds; advancing three bands respectively representing hours, minutes, and seconds along the clock face at respective speeds in correspondence with hours, minutes, and seconds of real time and providing indicia on the clock face indicative of hours, minutes, and seconds such that the positions of the bands on the clock face indicate time of day.
In further accordance with the invention, the method includes forming the graduations along a rectangular display.
In further accordance with the invention, the method includes forming the bands as light bands.
In a preferred embodiment, the method includes producing a display of light flashes when at least two of the bands of light representing hours, minutes, and seconds overlap.
In another preferred embodiment, the method includes producing a more intense display of light flashes when the bands of light representing hours, minutes, and seconds all overlap one another.

DETAILED DESCRIPTION
Reference is now made to FIGS. 1-9 which show a preferred embodiment of the invention.
FIG. 1 shows a face (10) of a clock (C) according to the invention without hour, minute, and second hands. The face (10) is formed by a rectangular screen with a linear array of graduations, or ticks, along its length representing time periods. The graduations begin with one half of a larger tickmark (20) followed by four narrower spaced tickmarks (30), which are then followed by another larger tickmark (20) which are in turn followed by four smaller spaced tickmarks (30). The pattern of one larger tickmark (20) followed by four smaller spaced tickmarks (30) repeats across the rectangular screen and ends with another half of a larger tickmark (20). The two halves of a larger tickmark at both ends of the rectangular screen represent the same time-space location, corresponding to “0”, “12”, or “60”. The larger tickmarks (20) are numbered 1-11 thereabove, representing hours, and are numbered 5-55 in intervals of five therebelow, representing minutes and seconds.
In a preferred embodiment, the hour-numbers (40) are shown in bold typeface and the minute/second-numbers (50) are shown in light typeface.
Shown in FIG. 2 is the face (10) shown in FIG. 1 with a second hand (60) represented by a light band covering the first smaller tickmark after the larger tickmark 15 and represents 16 seconds. A trail (100) is shown in the space between the larger tickmark 15 and the first smaller tickmark, illustrating the sweeping second hand. In this preferred embodiment, the second hand (60) is the narrowest of the three hands and may be red.
As the clock “ticks”, each hand jumps in increments from bar to bar of the graduation. This is illustrated in FIG. 3 in which the second hand (60) jumped from 16 seconds to 17 seconds in the direction of the arrow. Similar arrows will appear in the following figures to show the movement of the respective hand.
As shown in FIG. 4, one-half of the second hand (60) appears at tickmark “60” and the other half appears at tickmark “0” at the beginning and end of each minute.
Shown in FIG. 5 is the clock face of FIG. 1 with a minute hand (70) represented by a light band at 22 minutes and the second hand (60) at 59 seconds. In this preferred embodiment, the minute hand (70) is wider than the second hand (60), but narrower than the hour hand. In a preferred embodiment, the minute hand (70) is blue.
FIG. 6 shows the sweeping of the minute hand (70) to 23 minutes and the sweeping of the second hand (60) as the second hand (60) reaches the “60/0” tickmark, following the time shown in FIG. 5.
Shown in FIG. 7 is the clock face of FIG. 1 with an hour hand (80) represented by a light band at 7 hours, the minute hand (70) at 23 minutes, and the second hand (60) at 59 seconds. In a preferred embodiment, the hour hand (80) is the widest of the three hands, and may be green.
Following FIG. 7, as the clock ticks to the next second to 7 hours and 24 minutes as shown in FIG. 8, the second hand (60) advances to the “60/0” tickmark and the minute hand (70) advances to the “24” tickmark as explained above, and the hour hand also advances from the first smaller tickmark after 7 to the next smaller tickmark.
As each hour is divided into five intervals, each interval corresponds to a respective portion of the hour. The five intervals are shown in FIG. 9 in which the first interval (91) corresponds to 0-11 minutes past the hour, the second interval (92) corresponds to 12-23 minutes past the hour, the third interval (93) corresponds to 24-35 minutes past the hour, the fourth interval corresponds to 36-47 minutes past the hour, and the fifth interval corresponds to 48-59 minutes past the hour.
Referring now to FIGS. 10-12, a preferred embodiment of the visual pattern which is produced when two hands overlap will be discussed hereafter.
FIG. 10 shows the clock at 7 hours, 24 minutes, and 36 seconds. As the second hand (60) advances to 37 seconds, the second hand (60) and the hour hand (80) overlap one another as illustrated in FIG. 11. As the overlap occurs, a burst of flash appears to erupt from under the overlapped hands and rushes towards both sides of the clock. This burst of flash lasts for a few seconds as shown in FIG. 12 and fades away.
In every 12 hour period, the three hands overlap one another 12 times. FIG. 13 shows the times and positions when the three hands overlap.
As it is relatively rarer to have the three hands overlap, it is preferable to have a more special, distinctive, colorful, long lasting, or stronger burst of flashes when this occurs. For example, the two halves of the burst of flashes may move in opposite directions toward the ends of the screen, and may emerge on the opposite side of the screen to meet the other half of the flashes which may result in another display of flashes.
At midnight, it is preferable to have an even more special, distinctive, colorful, long lasting, or stronger burst of flash to accompany this event as shown in FIG. 14. This midnight show would attract visitors to the clock and the area.
Although the embodiment above includes a burst or flash erupting in a linear fashion out of the overlapping hands towards both sides of the clock, other visual patterns, including different shapes, colors, and configurations of light may be displayed. The invention may also be configured or programmed such that a unique visual pattern is displayed during a special event, for example, the new year.
FIG. 16 shows another preferred embodiment of the invention with different hours, minutes, and seconds hands. In this embodiment, the clock has a darker clock face surrounded by a dark frame, and the hours hand is shorter than the minutes hand, which is shorter than the seconds hand.
The invention may be implemented as a large LED or LCD display or other means of displaying, such as projection screen, TV, etc., which is controlled by a computer or a controller having computer instructions to display the clock as described above.
For example, FIG. 17 shows a controller (110), which may be an integrated circuit layout or a personal computer, connected to a display (120) and speakers (210). The controller (110) includes a processor (130), time keeping means (140) which may be an internal quartz clock such as the Real Time Clock chip found in computers, and storage means (150) which may be a computer readable medium storing instructions for displaying the invention. The controller (110) may be connected to an external power source (160) as shown or battery driven. The display (120) and the speakers (210) may draw power from the controller or from respective power sources. The controller (110) may also include synchronizing means to synchronize the time keeping means (140) to an accurate time source such as the NIST ((National Institute of Standards and Technology) Internet Time Service.
The invention may also be implemented to be run on a personal computer for home use, or as a website which can be downloaded or broadcasted over the Internet. At the time of this application, a working example of the invention may be viewed at www.mbeshir.com/eSela/
As shown in FIG. 18, the clock of the invention may be incorporated at the fascia of a building, which can be accompanied by external lights. The external lights may be connected to and controlled by the controller (110). The invention may also be incorporated in other environments and become a landmark or an attraction to visitors.
Although the invention is disclosed with reference to particular embodiments thereof, it will become apparent to those skilled in the art that numerous modifications and variations can be made which will fall within the scope and spirit of the invention as defined by the attached claims.
Thus, for example, although the face of the clock has been shown with dark graduations on a white face, the arrangement can be reversed and even various combinations of different colors can also be used for the face and the graduations. Similarly, the hour, minute, and second hands (60, 70, 80) may be differentiated by being of different colors, sizes, and shapes. Additionally, although the screen has been shown as being horizontal, it may be vertical, inclined, or of arcuate shape. Also, while the screen has been shown as rectangular, it could also be curvilinear or of other shape.
