  • Power source monitoring arrangement and method having low power consumption
    Patent number: 5907238
    Abstract: An electronic circuit and system (1) incorporating a battery system (30), power-discharge sensing circuitry (40) and sleep circuitry (10) all in electrical communication with each other. The sleep circuitry (10) detects the presence or absence of an external load on the battery system (30) by sensing changes in voltage across the battery's protection diode (D3). When no external load is present, the sleep circuitry (10) controls the power-discharge sensing circuitry (40) in an extremely low current mode (e.g., current is consumed by sleep circuitry (10), but no power supplied to power-discharge sensing circuitry (40)). This mode is also referred to as a sleep mode. Upon detection of a small voltage drop on the battery's protection diode (D3) caused by a power-consuming load on the battery, the sleep circuitry (10) supplies power to the power-discharge sensing circuitry (40).

  • Security system with infrared optical position detector
    Patent number: 4507654
    Abstract: A security device for determining the opening or closed condition of an access gate, such as a door or window hinged within an opening in a wall, has a detector unit mounted on the wall adjacent to the opening and linked to a remote control unit by a radio transmitter in the detection unit and a radio receiver in the control unit. The detection unit has an infrared generator and an infrared detector isolated from the generator, the detector and generator confronting a reflector mounted on the access gate when the access gate is closed. The reflector is translated from the field of the infrared generator when the access gate is open. The infrared generator is excited by a pulse generator to produce pulses of infrared radiation, and the scattered radiation from the reflector is detected by the infrared detector to produce electrical pulses coincident with the pulse generator.
