Title: Biography of Inventor William L Winstrom

Introduction: William L Winstrom is an accomplished inventor based in Andover, NJ (US). He holds a total of 8 patents, showcasing his innovative contributions to technology and healthcare.

Latest Patents: His latest patents include a Flexible Coil Pulsed Electromagnetic Field (PEMF) Stimulation Therapy System. This system utilizes a single-coil PEMF transducer to generate PEMF stimulation signals. The coil operates in a "bi-phasic" manner, allowing current to flow in two directions. A drive circuit recovers flyback energy from the transducer coil and transfers voltage to an energy recovery capacitance circuit. This process energizes and de-energizes the transducer to create the electromagnetic field. Additionally, he has developed a PEMF therapy system that employs a bi-phasic coil PEMF transducer, which is particularly suited for high-frequency operation.

Career Highlights: Throughout his career, William has worked with notable companies such as Cyberonics, Inc. and Amei Technologies, Inc. His work has significantly impacted the field of electromagnetic therapy.

Collaborations: William has collaborated with esteemed colleagues, including Anthony J Varrichio and John C Tepper. Their combined expertise has contributed to the advancement of PEMF technology.

Conclusion: William L Winstrom's innovative work in the field of PEM
