Abstract
A system for controlling operation of a device in response to the presence of a human body part includes a theremin for detecting the presence of a human body part in an area and producing a first output signal in response to the detection. A second sensor separately detects the presence of a human body part in the area and produces a second output signal in response to the separate detection. A processor determines the presence of both the first and second output signals and in response thereto provides a control signal to the device.
