Latest Patents
One of his latest patents is the "Position detector apparatus and method utilizing a transient voltage." This invention discloses a position detection method and apparatus that utilizes an electromagnetic probe as the control element in a relaxation oscillator circuit. The probe is energized by a pulse voltage waveform, and the decay time of the induced transient probe voltage is utilized to modulate the frequency of the pulse generator. The proximity of an electrically conductive or magnetic object influences the probe's transient voltage decay time, generating a frequency output that indicates the position of the object.
Another significant patent is the "Capacitance sensor circuit and method for measuring capacitance." This invention describes an improved oscillator circuit and method for measuring capacitance and small changes in capacitance. The circuit provides a digital output signal that has a frequency inversely proportional to the capacitance being measured. It is designed to be substantially immune to stray capacitance, has low sensitivity to noise and temperature variations, and is relatively simple and inexpensive to implement, providing high precision measurements.
