Title: Innovations by Douglas Andrews

Introduction

Douglas Andrews is an accomplished inventor based in Millis, MA (US). He holds 2 patents that showcase his expertise in the field of automated systems. His work primarily focuses on enhancing safety measures in cryopump technology.

Latest Patents

One of his latest patents is titled "Integration of automated cryopump safety purge." This invention provides a system and method to control a purge valve during unsafe conditions associated with a cryopump. An electronic controller is utilized to manage the opening and closing of one or more purge valves during these unsafe conditions. The purge valve can be either a cryo-purge valve or an exhaust purge valve, and it may be a normally open valve. The electronic controller can release the normally open valve in response to unsafe conditions and can delay its response for a safe period. This innovation ensures that attempts from other systems to control these valves during unsafe conditions can be preempted. Additionally, users are inhibited from manually controlling the purge valve during unsafe conditions. A power failure recovery routine may also be initiated in response to power restoration, ensuring safety even if the routine has been manually turned off by a user.
