Abstract: An electronic time piece senses and warns the electric residue of a secondary cell having electrodes of conductive polymer to a user during the rapid charge.The electronic time piece converts a kinetic energy produced by the user's motion into an electric energy. The electric energy is then outputted from a power generator coil as a charging voltage for charging a chemical reaction type secondary cell. The charged energy in the secondary cell is used to actuate a time piece circuit for indicating the time.The electronic time piece comprises an electric residue sensor unit which outputs an electric residue detection signal when the voltage in the secondary cell continues to exceed a reference voltage corresponding to an electric residue in the secondary cell for a predetermined time during the rapid charge.

Abstract: A time indicator is provided that includes a front layer and a back layer, each having an inner and outer surface. The front layer has a display region on its outer surface. An adhesive means is provided on the inner surface of the front or back layer for adhesively attaching the front layer and back layer to each other. An opaque viewing layer is included on the front or back layer and an activation agent is provided on the other layer. One surface of the opaque viewing layer is viewable from the display region when the front and back layers are adhesively attached to each other. A dye that is substantially non-migrating through the opaque viewing layer, overlies the other surface of the opaque viewing layer. When the inner surfaces of the front and back layers are contacted with each other, the adhesive means adhesively attaches the front and back layers to each other and activates the activation agent.

Abstract: A multifunctional electronic watch of the present invention displays data measured by a built-in atmospheric pressure sensor by means of a small atmospheric pressure pointer and an atmospheric pressure pointer. It is also capable of displaying a differential between the present atmospheric pressure and an atmospheric pressure three hours before by means of an atmospheric pressure tendency pointer. A dial ring attached around a clockface of the watch is formed with an atmospheric pressure scale, on the outer periphery of which is a rotation bezel formed with a height scale. The built-in sensor is accommodated in the watch so as not to project from the rotation bezel of the watch. Accordingly, an electronic watch which has additional functions of indicating environmental data such as atmospheric pressure without complicating the constitution can be realized.

Abstract: A time measurement circuit (100) measures a time interval between two events. The time measurement circuit (100) includes two digital phase counters (10' and 10"), a period counter (210), and a digital calculator (310). The first digital phase counter (10') converts a time interval from a leading edge of a start signal to a leading edge of clock signal following the start signal into a first binary number. The second digital phase counter (10") converts a time interval from a leading edge of a stop signal to a leading edge of clock signal following the stop signal into a second binary number. The period counter (210) converts a time interval between the two leading edges of the clock signal into a third binary number. The digital calculator (310) combines the three binary numbers to generate a number representing the time interval between the start signal and the stop signal.

The mechanism for switching the clock pulses to and from each clock is operationally connected to their electronic circuitry by means of an optical beam, e.g., an infrared beam which is directed alternately to a pair of sensors connected respectively to control circuits for each clock. No mechanical or electrical operational connections are present between the switching mechanism and the electronic circuitry.

Abstract: A chronograph mechanism comprises a coupling member (17) engaging, on the one hand, with a pinion (15") solid with the seconds wheel and, on the other hand, with the chronograph's seconds wheel (18). This coupling member (17) also carries a retractable finger (27) adapted to drive, each turn, the first rotatable member (35) of a cinematic transmission connecting together a rotatable member (38) of the minutes wheel to that of the hours counter (41). This transmission is indexed, between two drives by the retractable finger (27), by a jumper (51) engaged in an intermediate wheel (37) of this transmission. The coupling member (17) is controlled by two levers (44, 45), one lever (44) carrying a pin (44c) which, in the uncoupled position, locks the jumper (51) in the intermediate wheel (37)'s toothing. The minutes and hours counter rotatable members (38, 41), solid with zero setting cams (42, 43), are friction fitted on their respective axles.

Abstract: A method and apparatus for measuring very short time periods, or differences between two events, such as the delta-T between a trigger point on a waveform and a sampling clock edge of a digital oscilloscope. The delta-T measurements are made using the time-to-voltage transformation of an integrator. The output sweep ramp of the integrator is normalized to a fixed differential time and differential amplitude by correction current provided by a reference circuit that has a reference integrator substantially identical to the delta-T integrator. The reference integrator is operated at the same timing as the delta-T integrator, and an error correction loop furnishes the right amount of current to both integrators to normalize the peak voltage of both to a predetermined reference voltage.

Abstract: To achieve a multiple function portable electronic device providing improved ease of use by enabling the operation of selected functions to be sustained even while replacing the battery, switch end 190 is pushed out from battery housing hole 509 to one side by battery 59 when battery 59 is loaded, and is pushed by spring member 197 into battery housing hole 509 inside watch case 11 of the wristwatch-type pulse wave measuring device when battery 59 is removed from battery housing hole 509 after removing the battery cover. Switch end 190 thus automatically inputs the terminal voltage of a backup capacitance element from signal input terminal 510 to the IC. This causes the wristwatch-type pulse wave measuring device to switch from the normal operating mode to an energy conservation mode.
