  • Patent number: 5376975
    Abstract: A selective call receiver receives a selective call signal (400) comprising a preamble signal (410). The selective call receiver comprises receiver circuitry (102) for receiving and demodulating the selective call signal (400). A preamble detector (105) is coupled to the receiver circuitry (102) for detecting the preamble signal (410), and a battery saver circuit (126) selectively activates and deactivates the receiver circuitry (102) in response to a signal from a processor (114). The processor (114) provides the signal to the battery saver circuit (126) to deactivate and activate the receiver circuitry (102) during reception of the preamble signal (410) in response to and subsequent to the preamble detector (105) detecting a portion of the preamble signal (410).

  • Patent number: 4331978
    Abstract: Video display distortion in a television receiver introduced by input voltage excursions is compensated for by a voltage regulation circuit which tracks the changing input line voltage while automatically switching to an active filter mode once the line voltage has decreased to a predetermined level. This permits the removal of AC transients from the fluctuating input signal and avoids display degradation resulting therefrom.

  • Patent number: 4174892
    Abstract: A method and apparatus for automatically focusing a camera is described in which the camera has a stationary optical path and a scanning optical path for developing focusing signals. The scanning optical path is caused to undergo a range-finding reciprocation in which it reciprocates between first and second limit positions, as between the minimum lens focusing position and the infinite lens focusing position. Two focusing signals are generated during the range-finding reciprocation and the interval between the focusing signals is used to derive the distance to the subject. The lens is then positioned in accordance with the derived distance to the subject.

  • Patent number: 4076247
    Abstract: The disclosure relates to a moving target assembly for use in a target practice range. The moving target assembly includes a target, a target travel guide for guiding the target movement and including a pair of straight sections which are substantially at right angles to one another, and a chain drive running substantially parallel to the straight sections. The target includes selectively operable chain engaging devices so that the target may be selectively guided along one straight section or the other. The assembly also includes structure for returning the target to a home position. Also disclosed is a control for controlling a plurality of such assemblies, including selection of the targets, the speed of target travel, the raising and lowering of the targets, and the actuation of the chain drive motors.
