  • Signal coupler
    Patent number: 5434401
    Abstract: A signal coupler for incorporating in a smartcard or a base device comprises an optocoupling arrangement for exchanging power or data signals between the demountable device and the base device, thereby eliminating problems associated with wear of metal contacts and allowing convenient manufacture.

  • Phase winding detector and alternator charging system
    Patent number: 5376876
    Abstract: A phase winding detector (50) is preferably used to detect alternator (11) rotation in an alternator charging system (10). The detector (50) receives a single winding phase output signal (at 39) and utilizes a sampling apparatus (71, 74, 76) to provide a sampled phase output signal (at 75). A comparison circuit (70) provides an output by comparing the phase output signal with the sampled phase output signal, whereby a detection of variation in the phase output signal is provided (at terminals 85, 87 and 51). After initial detection of variation of the phase winding output signal, preferably additional circuitry (77, 79, 83) results in comparing the phase winding signal with a fixed reference threshold (V.sub.ref). Detection of a phase winding output signal is implemented without use of a substantial DC blocking capacitor and is implemented by monitoring only one input signal terminal.

  • Thermally dependent self-modifying voltage source
    Patent number: 5241261
    Abstract: A thermally dependent self-modifying voltage source (115) is constructed with a first reference circuit (301) having a control input (311), a primary output (117) dependent on the control input, and a thermally dependent secondary output (303). The thermally dependent self-modifying voltage source also includes a thermally dependent reference (309) with an output (307). The thermally dependent secondary output (303) of the first reference circuit (301) and output (307) of the thermally dependent reference (309) are coupled to inputs of an amplifier (305). The amplifier (305) has an output (313) coupled to the control input (311) of the first reference circuit (301), wherein the primary output (117) of the first reference circuit is dependent on the amplified difference between the thermally dependent secondary output (303) of the first reference circuit and the output (307) of the thermally dependent reference (309).
