Abstract: A programmable auxiliary control unit for a television receiver has switch selectable features which enable it the receiver to interface more easily to a variety of signal sources, by controlling the operating parameters of the television receiver. The controlled parameters are, for example, automatic turn-on, automatic autoprogramming, automatic forcing of the television receiver to a predetermined channel, automatic increasing of the volume at the television receiver, and automatic disabling of the numeric keyboard of the television receiver.

Abstract: Auxiliary control apparatus for an electronically controlled television receiver is coupled to the conductors between the keyboard and the control unit of the receiver to simulate user initiated power on and initial channel or other input source selection commands when AC line power is initially applied to the receiver. To cause this, the auxiliary control unit is responsive to the initial development of standby operating power by a standby power supply. Operating power for the auxiliary control unit is derived by drawing current from pull-up resistors connected to the conductors between the keyboard and the control unit. The auxiliary control apparatus is useful for use with institutional receivers which are to be turned on by the application of AC line power through a central control station and which are set to tune a predetermined channel or select another predetermined input signal source when turned on.

Abstract: A motor vehicle alarm system incorporates five integrated circuits mounted on a printed circuit board enclosed within a case. The integrated circuits include a high speed oscillator as a clock source, a twelve stage binary counter, a set of flip-flops used as memories, a three input AND gate, and a flip-flop used as the start or stop memory for the clock source. The alarm system becomes armed approximately four minutes and fifteen seconds after the ignition key is turned off. If a door is then opened, the alarm will be actuated unless the ignition switch is turned on within fifteen seconds.
