Abstract: An energy system for powering an electronic watch having a digital or analog time display, the system comprising a primary power source, such as a thermoelectric generator or solar cell, whose output is fed to an energy converter to produce an operating voltage for the electronic circuits and time display of the watch. The system further includes a buffer accumulator that is charged by the energy converter and acts to maintain the operation voltage when the primary source is inactive, thereby providing an uninterrupted supply of operating voltage. The watch also includes a status indicator which senses the prevailing condition of the energy system to produce a signal indicative thereof perceptible to the user of the watch.

Abstract: An electronic timepiece in which the output of a stable, highfrequency standard such as a crystal oscillator, is fed to a presettable frequency-divider to produce periodic low-frequency output pulses for actuating a time display. The frequency of the oscillator lies in a range somewhat below an assigned value producing, upon division, the desired number of output pulses for accurate timing, the resultant deficiency being made up by adding pulses to input stages of the divider sufficient to compensate therefor. In this way, one may manufacture crystals under far less restrictive tolerances than those imposed when the crystal is required to operate at the assigned frequency.

Abstract: A capacitor unit adapted to adjust the frequency of a crystalcontrolled oscillator in incremental steps, the oscillator serving as a frequency standard for an electronic timepiece. The unit is constituted by a bank of capacitors whose respective values fall into a binary series, each capacitor being associated with a switch arranged to connect the capacitor in parallel relation to the other capacitors in the bank, whereby the reactance presented by the unit may be varied incrementally by selective operation of the switches to create a reactance range whose lowest value is determined by the smallest capacitor alone, whose highest value is determined by the sum of all the capacitors in the bank, and whose intermediate values are determined by the capacitors singly or in shunt combinations thereof.

Abstract: A torsional fork transducer wherein the two lines of the fork are interconnected at their feet by a piezoelectric crystal operating in the longitudinal mode, the crystal being energized at a rate determined by the natural frequency of the fork to effect torsional vibration of the tines. Oscillators derived from a pick-up electrode on the crystal are applied to the input of an electronic amplifier whose output is fed to a drive electrode on the crystal to sustain the fork in vibration.

Abstract: A multicellular, solid-state radiation detector assembly adapted to produce exceptionally large signals in response to incident radiation, the detector being constituted by an array of individual surface-barrier or diffused-junction, radiationsensitive, semiconductive cells, each of which has a small area and a low internal capacitance. The cells in the array are unidirectionally connected in parallel relation with respect to current flow, but are otherwise electrically isolated from each other, whereby the overall capacitance of the array is low while the detection efficiency thereof is substantially equal to a unitary radiation detector whose surface area is equivalent to the aggregate area of the cells, the signal output from the multicellular detector being far greater than that yielded by the unitary detector.
