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.

[ What is claimed is:] [1.]1. A system for the dispensing of a fluid in response to the presence of a human hand, the system comprising:a fluid dispensing device for releasing a measured amount of fluid in response to a control signal;a theremin means for detecting the presence of the hand proximate the fluid dispenser and producing a first output signal in response to the detection;sensor means for independently detecting the presence of the hand proximate the fluid dispenser and producing a second output signal in response to the independent detection; anda processor for determining the simultaneous presence of both the first and second output signals and in response thereto producing the control signal.
