Latest Patents

Ching Chu holds a patent for an "Inwardly directed wave mode ultrasonic transducer, gas analyzer." This invention discloses an ultrasonic transducer designed to emit ultrasonic waves radially inward. The transducer is constructed using a strip of piezoelectric material laminated with two electrically conductive metal layers that are isolated from each other. In a preferred embodiment, the piezoelectric material is shaped cylindrically with continuous sinusoidal ripples along its circumference. These ripples are engineered to emit specific wavelengths at desired frequencies. The invention also details various methods for constructing and maintaining the sinusoidal shape of the transducer, including the attachment of rigid end caps and weaving the material through a nonconductive mesh cage. Additionally, the transducer is applied in a gas analyzer, where it analyzes gas by emitting ultrasonic waves into the gas and sensing the reflected waves.
