Abstract: A device for generating controlled vibration in an uncontrolled temperature environment includes a driving circuit that generates a signal having a first frequency and has a temperature-sensitive driving unit, a vibratory element coupled to the driving unit that vibrates at the first frequency according to the generated signal, and a temperature control circuit to control the temperature of the driving unit.

Abstract: A method and apparatus for automated field calibration of temperature sensors uses a series of readings including a reading of a known source, such as an LED, for use in calculating a factor that is compared to a reference for adjusting the sensor output signal. Calibration readings are taken more frequently after start up to compensate for sensor drift during storage, as opposed to less frequent readings during operation to compensate for slower sensor drift while operational.

Abstract: A television receiver with PIP circuitry provides a snapshot feature for freezing the main video display in the PIP display inset by operation of a special key on a remote control keypad. With the television receiver operating normally (PIP deactivated), one operation of the special key switches the main video signal to the PIP input and freezes the PIP display in its largest size and in the position it occupied the last time PIP was activated. A video message informs the viewer that a snapshot feature is operational. A subsequent operation of the special key switches the PIP signal to the PIP circuitry and unfreezes the display as in normal PIP operation. A further operation of the special key deactivates the PIP circuitry.

Abstract: A method for translating the generic, raw information of a broadcast on-screen program guide service into a displayable screen signal that can drive TV electronics, utilizing the step of building a virtual generic screen before creating the displayable screen signal in order to ease the translation burden from generic to TV specific information.

Abstract: A television display system having a remote control unit which sends different command codes, upon activation of the same button, dependent upon which mode the remote control unit is in; has a simplified operation by translating a noneffective command code from the transmitter into an effective command at the display unit when the display unit is not in a signal source which can act upon the noneffective command code. Further simplifying the keypad operation of the remote control transmitter by allowing function and adjustment keys to perform double duty depending on the operating mode of the display is also discussed.
