Title: The Innovations of Henry F. Cook
Introduction
Henry F. Cook is an accomplished inventor based in Penn Hills Township, PA. He has made significant contributions to the field of electrical engineering, particularly in the development of innovative testing circuits. With a total of 3 patents to his name, Cook's work has had a notable impact on the industry.
Latest Patents
One of Cook's latest patents is a self-testing monitoring circuit. This invention involves a self-testing contact closure test circuit and method that artificially creates invalid logic states to simulate switch malfunctions. This allows for the accurate identification of invalid states by the testing circuitry. The system is designed for use with switches that incorporate form 'C' arrangements, which typically have two pairs of contacts in opposite states.
Another significant patent is the self-compensating voted logic power interface with tester. This invention features a circuit with parallel connected groups of serially connected switches, where each switch is shunted by a high impedance resistor. This design creates a leakage path through each group of switches. A detector associated with each group generates a digital output signal that indicates the state of the switches in response to a sequence of test signals. The system compensates for large variations in supply voltage by incorporating the switches into a resistance measuring bridge circuit.
