摘要： 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.

摘要： A fluid dispenser includes a disposable reservoir for containing a fluid and a tube depending therefrom for dispensing measured quantities of fluid. The tube includes a fluid dispensing orifice and a plunger for forcing measured quantities of fluid through the orifice. A solenoid disposed adjacent tube magnetically engages and moves the plunger in order to cause the plunger to force the measured quantities of fluid through the orifice. A control system is provided which includes a Theremin antenna for sensing the presence of a user's hand beneath the orifice and providing electrical current to the solenoid to enable the solenoid to magnetically engage and move the plunger.
