Claim Text:
1. A system for reduced energy operation of a door closer comprising: a controller, the controller comprising a processor; a voltage storage device, the voltage storage device being operatively connected to the controller; and a generator, the generator being operatively connected to the controller and the voltage storage device, the generator generating a voltage responsive to movement of a door, the voltage charging the voltage storage device, wherein the controller enables power to a first sensor to read an angular position of the door only for enough time to insure an accurate reading the first sensor, wherein the controller enables power to a second sensor to read an angular position of a valve in the door closer only for enough time to insure an accurate reading the second sensor, and wherein the controller monitors a voltage level of the voltage storage device and initiates an orderly powering down of the processor when the voltage level of the voltage storage device falls below a defined level.
