Patent ID: 8827240

Claim:
A system for providing touch-free control of water, comprising: a water-flow control interface apparatus enclosing at least two touch-free sensors; a water-flow control valve configured to permit the flow of water through it, and, alternatively, to prevent the flow of water through it, in response to electronic signals; a logic processor configured to: receive a first input signal from a first touch-free sensor in response to the presence of an object relative to the first touch-free sensor and, if the system is in a non-paused-mode, then in response to the first input signal transmit a first output signal to the water-flow control valve instructing the water-flow control valve to permit the flow of water through it; determine, based upon input from the first touch-free sensor, that there is an absence of any triggering object relative to the touch-free sensor and in response to the determination, if the system is in a primary-water-flow-mode, transmit a second output signal to the water-flow control valve, said second output signal instructing the water-flow control valve to prevent the flow of water through it; receive a second input signal from at least a second touch-free sensor and, in response thereto, if the system is in the primary-water-flow-mode, change the system from the primary-water-flow-mode to a continuous-water-flow-mode, and transmit a third output signal to the water-flow control valve instructing the water-flow control valve to permit the flow of water through it; receive a third input signal from at least one touch-free sensor and, in response thereto, if the system is in the continuous-water-flow-mode, change the system from the continuous-water-flow-mode to the primary-water-flow-mode and transmit a fourth output signal to the water-flow control valve instructing the water-flow control valve to prevent the flow of water through it; receive a fourth input signal from at least one touch-free sensor and, in response thereto, if the system is in the non-paused-mode, change the system from the non-paused-mode to a paused-mode; and receive a fifth input signal from at least one touch-free sensor and, in response thereto, if the system is in the paused-mode, change the system from the paused-mode to the non-paused-mode.
