    Abstract: An electrophorectic display is used in a watch, allowing for a dynamic range of new shapes and environments of use. The present invention addresses many of the shortcomings of the prior art watch technology. Specifically, a watch that embodies the present invention is uses addressable reflective display technology such as electronic ink or gyricons. This allows a watch display that features some flexibility. Further, the display can be shaped into a variety of interesting and novel designs that cannot be accomplished using prior art displays. The flexibility of the display also allows for the novel placement of the watch display. For example, the display can be placed onto a shoe, allowing a runner to see the time without having to move his arm into a viewing position. The watch display could also be placed into a wallet, or on a purse or belt. Any flexible garment or accessory could now incorporate a watch.

  • Patent number: 5898645
    Abstract: A time-keeping section is programmed in such a manner that a predetermined number of virtual particles are caused to reciprocatively move between two virtual space regions successively, and the time-keeping section can sequentially keep time with accuracy using, as a basic time unit, a time required for the predetermined number of virtual particles to make a single travel from one of the space regions to the other space region. With the time values yielded by the time-keeping section, it is allowed to accurately accumulate the basic time unit over a preset time period (e.g., time data for 1,000 years). By incorporating such a time measuring device in each selected computer, accurate common time can be set for shared use among computers connected in a network and also with a computer loaded in an artificial satellite operating far from the earth. In addition, communication among the computers and remote control of any of the computers can be performed very smoothly.

  • Patent number: 5870180
    Abstract: A time measurement device useful with laser range cameras and time-of-flight measuring methods includes a light transmitter responsive to start and stop signals for transmitting the light during a time interval to be measured, and a light receiver for receiving the light and for providing an output signal related to an exposure of the light during the time interval time between start and stop signals to the transmitter The output signal thus providing a measurement of the time between the start and the stop signals. The transmitter includes a light emitting diode to which an electrical current is provided for generating a constant output light source for the transmitter. The light receiver includes charged coupled devices (CCD) having a linear response to an amount of exposure to the light received from the light transmitter. As a result, the CCD provides the output signal in a linear relationship to the amount of exposure to the light, and thus a measurement of the time interval.

  • Patent number: 5757730
    Abstract: To graphically portray the diminution of the last minute before commencement of a next hour in a balanced digital time display, six horizontal elements of a pair of 7-segment arrays of display elements are activated immediately after one remaining minute and zero seconds. These six elements are each individually flashed for and extinguished after ten second intervals, in a sequence that begins with the top element of the outermost array, spaced farthest to the left from the next hour digit, and progresses to the middle and bottom elements of that array, followed by the top, middle and bottom elements of an intermediate array, located between the outermost array and the next hour digit. This sequence provides descending flashing elements in three ladder-like steps down each array, the outermost array graphically portraying the diminution of the first thirty seconds and the intermediate array the diminution of the second thirty seconds of the last remaining minute.

  • Patent number: 5748568
    Abstract: A watch or clock display shows hours as large digits and the minutes past the hour as the incremental filling of a familiar or regular figure. The digits and the partially filled figure are superimposed to make maximum use of the space available for the display.At the new hour, and for a predetermined number of minutes thereafter (say five or 7.5), only the hour number is shown in the center of the display. Then the first of successive segments of the figure are displayed. As the hour progresses, the figure becomes more nearly filled by increments.

  • Patent number: 5726953
    Abstract: An electroluminescent ("EL") lamp has EL material sandwiched between front and back conductive layers, which are disposed on a transparent substrate. The indiciae are formed from ink or other material deposited on the second surface of the front conductive layer, thereby completely burying the indicia within the EL lamp. The material may be transparent or colored, conductive or insulating, or made with an EL phosphor. The buried indicia provide sufficient contrast, when viewed with the EL lamp in an illuminated or non-illuminated state, to be seen. The present invention also describes a method for fabrication of such EL lamps.
