Abstract
A low-cost, simple ultrasonic sensing system has an increased detection range. The ultrasonic sensing system may be implemented as part of a load control system for controlling the power delivered from an AC power source to an electrical load. The load control system may comprise a load control device for controlling the power delivered to the electrical load, an ultrasonic receiver for receiving ultrasonic waves characterized by an ultrasonic frequency, and an ultrasonic transmitter located remotely from the ultrasonic receiver. The load control device controls the power delivered to the electrical load in response to the ultrasonic waves received by the ultrasonic receiver. The load control device may include the ultrasonic receiver and may be a wall-mounted load control device. The ultrasonic receiver may be a wireless ultrasonic receiver for transmitting wireless signals to the load control device in response to the ultrasonic waves received by the ultrasonic receiver.
