Title: Roy K. Yamanouchi: Digital Watch Inventor

Introduction

Roy K. Yamanouchi is an inventor associated with Tempe, Arizona, and Motorola Corporation. His patent work includes digital-watch technology, and the supplied information credits him with 2 patents.

Latest Patents

Yamanouchi’s listed patents describe a digital watch that uses a clock-signal generator and control circuitry to coordinate the display of time and date information. In its normal mode, the watch displays hours and minutes, while additional circuitry allows users to view seconds and date information and to set the hours, minutes, and date.

The design uses three functional switches, which may be incorporated into the watch stem. Operating one switch, such as by pushing in and releasing the stem, first displays seconds and then briefly displays the date before returning to the normal hours-and-minutes display. The two supplied patent descriptions are substantially similar and emphasize this compact, switch-controlled interface.

Career Highlights

Yamanouchi’s documented patent contributions focus on digital-watch display control and user interaction. The described system combines multiplexed information, a visual display panel, and a limited number of controls to provide several functions through a streamlined interface.

Collaborations

The supplied information identifies Richard S. Walton and Richard G. Daniels as Yamanouchi’s coworkers. It also associates his work with Motorola Corporation.

Conclusion

Roy K. Yamanouchi’s listed inventions center on a digital watch that efficiently presents time and date information through multiplexed display circuitry and three functional switches.
