Abstract: An electronic timekeeping system is implemented in bipolar integrated circuit technology for displaying time by way of a digital display. The bipolar circuitry is implemented utilizing integrated injection logic with asynchronous counters having outputs synchronized with the clock before coupling to the succeeding counter function, such as between the seconds and minutes counters. "D" flip-flops are utilized such that a D input is provided instead of a D input.

Abstract: A voting machine employs a scroll-type multi-layer ballot structure including removable strips carried by the upper layer and a pressure responsive means in the lower layer to reproduce markings made on the removable strips. Each removable strip carries a voter number so that an audit of each ballot can be made by the voter without revealing his identity. The multi-layer scroll-type structure is carried behind a panel having a slot therein extending in the direction of the removable strips and a door covering the slot which is prevented from opening to provide access to the strips in response to operation of the mechanism which senses whether or not a strip has been removed.

Abstract: A quartz crystal timepiece incorporating a vibrator unit is disclosed. The vibrator unit is hermetically sealed in a case on which a condenser is fixed and the condenser compensates the oscillating frequency of said vibrator unit to a predetermined center frequency by suitably selecting the capacitance of the condenser after measuring the natural frequency of the vibrator unit. Then there is no need to adjust each vibrator unit to the predetermined center frequency during assembling process.

Abstract: An indicating device for use in an electronic watch circuit indicating visually on the dial of the watch that the power cell in the circuit is operating properly and the circuit itself is operating properly. Cessation of the visual signal indicates that the cell should be replaced. The device uses a light-emitting element energized intermittently by pulses generated in the watch's electronic driving circuit. The threshold voltage of the light-emitting element is higher than the voltage necessary to adequately drive the driving circuit for keeping time accurately. A drop of the voltage below this threshold results in absence of light emissions and this indicates the cell is near exhaustion and must be replaced.

Abstract: A wristwatch has a plurality of light emitting digital readout elements which are located along one end of the watch above the watchband. A hermetically sealed time capsule is enclosed within the watch case and includes an integrated circuit chip which divides the frequency output of a battery powered quartz crystal oscillator into a series of pulses which are counted and selectively interrogated to provide a series of electrical outputs corresponding to seconds, minutes, hours, days, months and years. The time capsule includes sealed control switches which are actuated by magnets slidably mounted on the case and which provide for selecting different outputs for visual display on the readout elements, corresponding to either hours and minutes, month and day or seconds. The electronic circuitry automatically compensates for 28, 30 and 31 day months as well as for leap years, and the readout may be selected for repetitive 12 hours or 24 hour display.

Abstract: The face of a watch or clock is made up of electro-optical devices, such as liquid crystal devices, arranged to present radial bars each divided into an inner segment and an outer segment and the segments can be illuminated by an electronic drive circuit having a time-base generator such as a quartz-crystal oscillator. The drive circuit has a time multiplex system for scanning the bars and selects segments for illumination such that a minute hand is simulated by illumination of both segments of a bar, an hour hand is simulated by illumination of an inner segment alone, and a seconds display is provided by illumination of the outer segments in turn.

Abstract: An electronic timepiece in which a liquid crystal display panel is employed has a maximum display surface area when the electronic timepiece components, including the battery, are mounted behind the display panel. Optimally, the components are mounted in a non-overlapping arrangement.

Abstract: The termination arrangement comprises a two conductor hairspring and/or hub arrangement in an electric watch for coupling drive pulses to a balance wheel drive coil. A metallic hairspring, which is fastened to the hub, has a conductor which is insulated from the hub and balance wheel staff or arbor. A contact - metallic washer like - member is bonded to the hairspring collet such that the contact member is electrically insulated from the hairspring colet. The contact member is, also, electrically connected with one end of the second conductor on the hairspring. And a helical type spring-conductor having less than one full turn in length is bonded to the balance wheel between the hairspring-hub arrangement and the contact member. The helical type spring at the end which is bonded to the balance wheel is electrically connected to one end of the balance wheel drive coil. The other end of the spring-conductor is maintained in electrical contact with the contact-washer member by the pressure of the spring.

Included is time sharing circuitry to enable common display drivers for the timekeeping and calculating modes as well as power sharing circuitry to enable the use of inexpensive and reliable P-MOS circuitry in the calculator mode without constantly dissipating power. A time-zone setting circuit utilizes logic circuitry to automatically enable the user to change time by direct access to the existing keyboard assembly.

Abstract: A one button-switch time display set and adjustment apparatus for an electronic timepiece having a digital electro-optic display. The (time) information being displayed is set or adjusted by depressing and holding depressed the buttonswitch which causes the display indicia, i.e. digit (s) and other time display intervals, each to flash or flicker separately in a predetermined order. If the button-switch is released while the segment to be adjusted is being interrogated, indicated by the flickering or flashing of that indicia, the interrogation operation or sequence is interrupted and that indicia continues to flicker. Depressing and holding depressed the button-switch again, for a predetermined time, causes updating of the interrogated indicia at a 1 HZ rate. Releasing the button-switch stops the updating of the selected display indicia and causes the timepiece to return to the normal running mode or operation.

Abstract: Ornamental clock having a parallelogram formed of the short and long clock hands and two sets of links pivotally linking the hands. The profile of the parallelogram changes continuously and variously as the clock hands travel about the dial plate center in order to provide a fantastic aesthetic effect to indicate time in conjunction with the time indicia.

Abstract: A balance wheel for a horological instrument comprises a substantially annular rim having an enlarged counterweight portion and carrying a body (e.g., coil, magnet). The balance wheel is designed so that the body position is normally offset from the axis of the balance wheel in order that variations in body weight cause a related movement of the balance wheel about the axis. The rotation of the axially supported and initially unpoised balance wheel presents a portion of the counterweight to a stationary tool. The counterweight portion is of a predetermined configuration and the wheel is so designed that the tool removes sufficient material to poise the balance wheel.
