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.

Abstract: The bi-stability of electrophoretic and gyricon display technologies allows a display to maintain its image for a period of time without the driving electronics activated. The watch takes advantage of this attribute by being powered once a minute. This minimizes power consumption while not decreasing the functionality of the watch. Unlike LCDs, every segment of an electrophoretic display can be addressed by a conductive matrix, even segments encircled by other addressable segments. This allows the watch to have a visual alarm wherein every segment is inverted at a predetermined rate. In other words, time could be displayed in dark numbers against a light background. The image would then be inverted so that the light numbers would be displayed on a dark background. The display can be purposefully forced to all light or all dark until the users queries the watch for the time. This provides an aesthetic effect until the user actually needs to see the time.

Abstract: A bidirectional multispeed indexing control system for a display unit which has an increment input and a decrement input so as to be controllable to sequentially index through an ordered list of discrete elements. The control system has a two-button user interface. The user presses one button to increment once, and holds that button to continuously index at a slow fixed speed. To increase the indexing speed, the user presses the second button while continuing to hold the first button. Indexing speed will continue to increase until either a maximum speed is reached or the user releases the second button, at which point the indexing speed decreases from the value reached while holding the second button. To stop indexing, both buttons are released. To increment in the opposite direction (i.e., decrement), the order in which the buttons are pressed is reversed.

Abstract: When an inclination switch SW3 is turned on by inclining a wristwatch 12 up at 12 o'clock within a predetermined time after an acceleration switch SW2 is turned on in a state where an auto mode on/off subswitch SW1-1 is on, a lighting circuit lights up an electroluminescence panel EL and puts off same automatically after a predetermined time has passed. If the auto mode subswitch SW1-1 is off, there is no possibility that the panel EL will be lighted up even when the user makes a motion to look at the time displayed on the wristwatch. As a result, the panel EL is not recklessly lighted up excluding by the user's intended motion, useless power consumption is suppressed to prolong the life of a battery used.
