Latest Patents

William H. Ham holds a patent for a "Pyro/piezo sensor with enhanced sound response." This invention is a combination thermal and vibration sensor designed for use in sleep monitoring equipment. It features a thin film of plastic that exhibits both pyroelectric and piezoelectric properties. By incorporating a layer of foam material that covers only a predetermined portion of one major surface of the film layer, the thermal mass of the sensor is altered. This modification allows for the pyroelectric signal to be more easily isolated from the piezoelectric signal using conventional signal processing techniques. The absence of foam on the remaining portion of the film ensures that the piezoelectric properties are not dampened or attenuated.
