Title: The Innovative Contributions of John E. Gillis
Introduction
John E. Gillis is a notable inventor based in Peterborough, Canada. He has made significant contributions to the field of liquid level sensing technology. His innovative approach has led to the development of a unique piezoelectric liquid level switch.
Latest Patents
Gillis holds a patent for a liquid level switch that is designed to be immune to standing wave effects. This invention provides an unequivocal response to liquid contact. The switch incorporates an electrical oscillator circuit that includes frequency defining elements in both feed forward and feedback circuit paths. The piezoelectric crystal device used in the feedback path is constructed to have a lowest frequency vibration mode in air, which is substantially equal to a first frequency defined by the frequency defining element in the feed forward circuit. This mode is suppressed by acoustic coupling of the device to a body of liquid, allowing for a clear distinction between air and liquid contact.
