Microprocessor Based Air Inflation Control System
US Patent:
4694409, Sep 15, 1987
Filed:
Jun 25, 1984
Appl. No.:
6/623871
Inventors:
Michael E. Lehman - York PA
Assignee:
Monorail, Inc. - Auburn NY
International Classification:
B60C 2300, G05D 700, G06F 1521
US Classification:
364558
Abstract:
A microprocessor based system for monitoring the air pressure within an inflatable device and controlling the supplying of air to or venting of air from the device, as needed. A microprocessor based system controller includes controls for setting a desired air pressure signal and an input for receiving an actual air pressure signal from a pressure transducer connected to the inflatable device. If the desired air pressure signal is less than the actual air pressure signal, the system controller provides a vent control signal for application to an air vent control device to cause venting of air from the inflatable device. If the desired air pressure signal is greater than the actual air pressure signal, the system controller provides a fill control signal for application to an air inflating device to provide air to the inflatable device. In addition, the system controller provides a compressor actuation signal for application to an air compressor to provide air to the air inflating device as needed and an intermittent indicator signal for indicating provision of air to or venting of air from the inflatable device. The fill and vent control signals are of durations determined by the difference in the desired air pressure and the actual air pressure, following which the actual air pressure is again monitored and compared with the desired air pressure and, if appropriate, the filling or venting cycle repeated.
