摘要： A digital display electronic wristwatch including a quartz crystal high frequency time standard having a natural frequency in the MHz range is provided. The quartz crystal time standard is incorporated into an oscillator circuit that produces a high frequency time standard signal having the same frequency as the frequency of vibration of the time standard. A divider circuit is formed from a plurality of series-connected divider stages and produces a low frequency reference signal in response to the time standard signal. Series-connected counters are coupled to the divider to produce time-keeping signals in response to the low frequency reference signal being applied thereto, and digital display elements are adapted to display time in response to the time-keeping signals produced by the respective series-connected counters.

摘要： An improved digital display driving circuit is provided. The display includes first and second display digits, the first display digit and second display digit being respectively formed by a plurality of segment electrodes, at least one digit electrode spaced apart from the segment electrodes and material disposed between the segments electrode and the digit electrode. Regions of the material are adapted to be rendered visually distinguishable from adjacent regions by the application of an electric field across the region. The regions of the material in registration with the segment electrodes are rendered visually distinguishable in response to a predetermined potential difference being applied across any one of the respective spaced apart segment electrodes and the digit electrodes. The invention is characterized by the first digit electrode and second digit electrode being referenced during alternating driving intervals of time to a potential such that the regions of the material in registration therewith are prevented from being rendered visually distinguishable. Each of the segment electrodes forming the first digit are coupled to a corresponding segment electrode forming the second digit to define a plurality of segment electrode pairs. A memory includes a plurality of outputs coupled to each pair of segment electrodes to reference each pair of electrodes to one of a first drive potential and second drive potential to be compared during each driving interval of time with the potential of the respective digit electrodes spaced apart therefrom, and a shift register adapted to receive a drive signal and in response thereto write-in the drive signal to the memory prior to each driving interval of time.

摘要： A touch sensitive input particularly suited for use with an electronic wristwatch, an electronic calculator or a combination thereof is provided. The touch sensitive input includes a touch sensitive contact connected to the input of a detector circuit, the detector circuit input being normally referenced to a first potential for producing a detector circuit output signal representative of the first potential. Engagement of the touch sensitive contact selectively references the detector circuit input to a second potential and in response thereto produces a detector circuit output signal representative of the second potential. The detector circuit includes at least an MOS or C-MOS input stage. Additional circuitry is provided for eliminating chatter in the output signal produced by the input stage, for preventing the producing of two signals representative of the unintended engagement of more than one touch sensitive contact, and for providing an indication that a touch sensitive contact has been inadvertently engaged.
