Title: The Innovative Contributions of Stephen R. Matté
Introduction
Stephen R. Matté is a notable inventor based in Norfolk, MA (US). He has made significant contributions to the field of vacuum technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is an electronically controlled vacuum pump. This vacuum system comprises an integral assembly that includes a vacuum pump with a drive motor, a purge valve, a roughing valve, and an electronic control module. The system features both a cryogenic vacuum pump and a turbomolecular vacuum pump. The control module is equipped with a programmed processor that controls the motor and valves, allowing for user programmability to establish specific control sequences. The electronic control module is removable and connects to other devices through a common connector assembly. In the turbomolecular pump system, the proper introduction of a purge gas through the purge valve is detected by monitoring the current load on the pump drive or foreline pressure. The system is designed to test the purge gas status by closing and then opening the purge valve while monitoring drive current or pressure. After a power failure, the controller continues normal operation of the turbomolecular pump as long as the pump speed remains above a threshold value. If not, the vent valve opens, requiring a start-up sequence. During shutdown, power to the pump drive motor is discontinued, and the vent valve is opened before closing the roughing valve.
