Patent number: 4773051Abstract: The circuit comprises a counter (13), a generator (11) that produces a reference signal (Sf) made up of pulses, and a two-input AND gate (10). One input of the AND gate is connected to the generator while the other input receives a signal (Sx) produced by a bouncing contact (X) as it switches from an open position to a closed position and vice versa. The output of the AND gate is connected to the clock input (C113) of the counter, which further has a reset input (R13) connected to the output of an inverter (14) whose input receives the signal produced by the contact.Opening of the contact causes the reference signal to be blocked by the AND gate and the counter to be reset. Closure of the contact causes the AND gate to open to the reference signal whose pulses then increment the counter and the latter, upon its contents reaching a predetermined value, issues an output signal (S13) in the form of a pulse.Type: GrantFiled: December 2, 1987Date of Patent: September 20, 1988Assignee: ETA SA Fabriques d'EbauchesInventor: Bertrand Soltermann

Patent number: 4536095Abstract: A crown switch actuator in a solid state analog wristwatch rotates in either direction and is movable axially. The actuator stem has a flat portion which rotatably operates a rocker contact spring against contact pads on a printed circuit board to alternately close first and second switches. The rocker contact spring also detents the switch actuator in one of two axial positions and retains the crown actuator in the watch case. Third and fourth switches are alternately closed by axial movement of the crown actuator stem. In a first detented axial position, the third switch is closed. In a second detected axial position, the third and fourth switches are open. In a third axial position, the fourth switch is closed. An extension arm on the detent rocker contact spring provides for releasing the crown actuator from the watch case.Type: GrantFiled: September 13, 1984Date of Patent: August 20, 1985Assignee: Timex CorporationInventors: Paul Wuthrich, Lyman R.

Patent number: 4509867Abstract: An electronic timepiece movement includes a control stem slidably guided in a radial passage of a base plate. Pulling on this control stem brings a return spring acting on the stem into contact with a stud which is carried by the substrate of an electronic circuit module of the movement. This connects a conductive lead to ground, which controls an operation function of the timepiece. The pull-out control stem and associated return spring can be replaced by a push-in member and by a return coil spring located in said passage. The stud is then positioned in a hole of the substrate of the electronic circuit, which hole is situated opposite to the longitudinal axis of the passage. Pressure exerted on this push-in member places a portion thereof into electrical contact with the stud and this connects the lead to ground, as before. Thus, the movement can according to choice be completed for operation either by a push-in control movement or by a pull-out control stem movement.Type: GrantFiled: December 22, 1983Date of Patent: April 9, 1985Assignee: Ebauches Electroniques S.A.Inventors: Willy Cleusix, Francois Nikles

Patent number: 4449832Abstract: Manually actuatable means are provided for programming or time setting a digital-electronic time switch device which utilizes an analog program input eliminating the need for a separate data display terminal. The time setting system includes a manually adjustable dial assembly having at least one adjustable indicator arm movable about an annular time marking scale and connected through a train to a command encoder. The command encoder includes a wheel connected to the dial train for forward or backward rotation. The wheel is suitably constructed, such as by radial slits to code dial assembly settings for triggering a digital information transducer, such as an opto-electronic device, which signals an electronic counter. The electronic counter adjusts the device data memory by specific time units in relation to the digital information received by the command encoder. The dial assembly inherently indicates the adjusted time setting to the operator in readily observable analog form.Type: GrantFiled: March 17, 1982Date of Patent: May 22, 1984Assignee: Dieter Graesslin FeinwerktechnikInventor: Gerd Kammerer

Patent number: 4419018Abstract: The watch comprises a plurality of stores, each containing a particular item of time data and each producing an output signal representing the data therein. A single operating button is displaceable by the user of the watch, on the one hand in the axial direction between a pushed-in position and a pulled-out position for which a switch is respectively open and closed, and on the other hand rotatably. Rotation of the button closes and opens two more switches by two cams rotationally displaced so that two pulse trains are produced with a phase relationship indicating the sense of rotation. A circuit processes these pulse trains to produce UP pulse for one sense of rotation and DOWN pulses for the other sense of rotation. These pulses are used to correct the value in a selected store. The particular store to which the correction signal is applied is selected by axially displacing the operating button from the pushed-in position to the pulled-out position a predetermined number of times.Type: GrantFiled: January 29, 1981Date of Patent: December 6, 1983Assignee: Ebauches Electroniques, S.A.Inventor: Clement Meyrat
