Touch-free water-control system
First Claim
1. A method for controlling touch-free operation of a flow of water from a faucet including a first touch-free sensor and a second touch-free sensor, the method comprising:
- receiving a first sensor signal in response to a first activation motion;
retrieving a flow state of the second touch-free sensor in response to the received first sensor signal, said flow state indicative of at least one of the following modes;
a pause mode or a non-pause mode, wherein the second touch-free sensor cannot allow the flow of water from the faucet in the pause mode; and
changing the flow state of the second touch-free sensor from the pause mode to the non-pause mode or the non-pause mode to the pause mode based in part on the retrieved flow state and the received first sensor signal,wherein said first activation motion is related to a presence of an object in front of the first touch-free sensor and wherein at least said retrieving is implemented by a hardware processor.

Abstract
A system and method of Touch Free Automatic faucet controlled by electronic sensors provides a Primary-Water-Flow-Mode, a Continue-Water-Flow-Mode, a Temperature-Control-Mode, a Faucet-Pause-Mode, an Adjust-Water-Flow-Mode and a Flow-Temperature-Default-Setting-Mode for users to control faucet water flow and water temperature without touching any parts of faucet body. The system comprises at least three electronic sensors, a logical processor circuit board, an electricity power supply package, a water flow control valve assembly, a temperature control valve assembly, at least one faucet body housing and at least one inlet fluid line. From the outputs of the sensors, the logical processor responds to the flow control valve assembly and to the temperature control valve assembly to control water flow and temperature to the faucet spout.

14. A water-flow control apparatus for controlling touch-free operation of a flow of water from a faucet comprising:
-
a first touch-free sensor comprising a first detection zone away from a sink; a second touch-free sensor positioned in a faucet spout and comprising a second detection zone towards the sink; and a hardware processor configured to; receive a first sensor signal in response to a presence of an object to in the first detection zone of the first touch-free sensor; retrieve a first flow state of the second touch-free sensor comprising at least a pause mode or a non-pause mode from a memory responsive to the presence of the object relative to the first touch-free sensor, said pause mode configured to disable touch free operation in the second detection zone of the second touch-free sensor and prevent flow of water and said non-pause mode configured to enable touch-free operation in the second detection zone of the second touch-free sensor, wherein the first touch-free sensor is enabled during pause mode; and store a second flow state of the second touch-free sensor in the memory different from the retrieved first flow state responsive to the presence of the object in the first detection zone of the first touch-free sensor. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A computer storage system comprising a non-transitory storage device, said computer storage system having stored thereon executable program instruction that directs a processor, which controls touch-free operation of a flow of water from a faucet, to at least:
-
receive a first sensor signal from a first touch-free sensor in response to a first activation motion; retrieve a flow state of a second touch-free sensor in response to received first sensor signal, said flow state indicative of at least one of the following modes;
a pause mode or a non-pause mode, wherein the second touch-free sensor cannot allow the flow of water from the faucet in the pause mode; andchange the flow state of the second touch-free sensor from pause mode to non-pause mode or non-pause mode to pause mode based in part on the retrieved flow state and the received first sensor signal, wherein said first activation motion is related to a presence of an object in front of the first touch-free sensor. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29)
