Latest Patents

Kawagishi holds a patent for a "Cross-oil instrument having testing apparatus for vehicular sensor." This innovative apparatus is designed to test a cross-coil instrument that features a pointer and a sensor. The sensor detects conditions and produces a signal indicative of the sensed condition. The converter then translates this signal into a deflection of the pointer. The apparatus includes a fault detector that identifies disconnection faults and generates a command signal. Additionally, a test signal generator responds to this command signal, producing a predetermined test signal to the converter, which moves the pointer to a specified position. This invention allows for the assessment of the operational accuracy of the cross-coil instrument by comparing the actual pointer position with the predetermined position when a connector in the signal line is disconnected.
