摘要： A drying apparatus (10) for a vehicle washing system maintains blower air bags (18) a predetermined distance from the vehicle without contacting same providing forced air against the vehicle. Ultrasonic sensors (66) are provided on front and back sides of the nozzle (26) for sensing objects within a predetermined distance in combination with control circuitry. The control circuitry controls a motor (42) to retract a cord (36) to in turn raise or move out of the path of the vehicle, the air bag (18) maintaining the predetermined distance from the vehicle. The signals from each of the sensors (66) are each combined to control the motor. The control circuitry includes and oscillator, counter circuit and integrator for producing a distance ramp, and an echo detector for receiving the reflected signal for comparison to the distance ramp to determine the distance of the sensor (66) from the object.

The sensors (66) include a housing for supporting same with apertures therethrough for transmissions and reception of ultrasonic signals. The housing includes sawtooth projections extending between the apertures to block transmissions from direct reception by the receiver.
