TL;DR: An automatic programmed ventilation control system for operating a fan includes a fan drive circuit; a duty, cycle control circuit including means for selecting a duty cycle and means for setting the selected duty cycle as mentioned in this paper.

TL;DR: In this paper, an amount of time that air has been delivered from an air handler to a space is tracked, and based on the tracked amount of air, at least one turn-on time or one turnoff time of the delivery of air from the handler to the space is controlled.

TL;DR: An aneroid volume determining system includes an airtight chamber for holding a subject whose volume is to be detected; a volume adjuster including an inflatable container for varying the pressure in the chamber; sensing equipment including a pressure transducer for sensing the volume of the subject in the deflated and inflated states of the container; and controlling equipment, which can calculate the volume in response to the pressure sensed in the volume with and without the subject present in a chamber and which equipment provides control signals to the volume adjusters for automatically controlling the inflation and deflation of the inflatable
