  • Low power regulator system and method
    Patent number: 7064671
    Abstract: Methods are disclosed for collecting sensor data in a pressure regulator system including a controller and a plurality of sensors. The controller and each of the individual sensors are activated as required to collect sensor data during a sampling period thereby reducing the amount of power consumed by the pressure regulator system. Further power conservation measures are implemented by using a battery sensor to monitor the capacity of the pressure regulator battery and placing the pressure regulator in reduced power consumption operating modes as the capacity of the battery is reduced.
    Type: Grant
    Filed: February 28, 2001
    Date of Patent: June 20, 2006
    Assignee: Fisher Controls International LLC
    Inventors: Richard J. Vanderah, Paul R. Adams, David E. Woolums, Jon B. Milliken
