摘要： In a capacitive key for use in a keyboard, an operator depresses a plunger which alters the separation between the plates of a capacitor, thereby altering its capacitance. It is desirable to provide plunger overtravel which permits further depression of the plunger after the capacitor has been altered. In the present invention a portion of the movable capacitor plate is formed into a spring which elastically deforms after the capacitor has been altered, to permit overtravel of the plunger.

摘要： A capacitive transducer providing an output for a signal with respect to an on-off mode which depends on a signal having a step function, the signal source is fed to a transistor or suitable amplifier having its base connected to a capacitance sensing means. Resistors are provided for appropriate biasing, current limiting and drain functions as well as capacitors for capacitance balancing purposes. The capacitance sensing means can comprise a touch switch which when touched has its capacitance increased causing the device to function. The change in capacitance can be registered with respect to the rise time or the fall time of the signal, or the leading or trailing edge of the wave. The transistor or amplifier is connected to a load so that when a change of capacitance is sensed, the change will be registered. Other embodiments can incorporate differential amplification means and means to drive the active components with the voltage of the signal source or the clock voltage. The transducer element maybe incorporated into mechanical moving elements that provide an electrical analog of such movement.

摘要： A multifunctional wrist watch combining the functions of time-indication with other functions, for example a calculator. The watch has a glass in which pick-ups are provided for detecting the passage of a finger of a user over the surface of the glass and recognition circuits for converting the trace detected into a logic signal for processing by a calculator circuit provided in the watch case. The output of the calculator is then displayed by the electro-optical display on the watch. The detection and recognition facility may also be utilized for correction of the date and time settings of the watch.
