Faucet assembly

A faucet apparatus for providing user-controllable continuous water flow, the faucet apparatus comprising:

• a spout configured to direct water flow into a sink;
• a logic processor;
• a first sensor zone comprising a first sensor, said first sensor facing the area in which the spout is configured to direct water to flow;
• and
• a second sensor zone comprising a second sensor, said second sensor configured to detect an object in the second sensor zone and respond to the detection by providing input to the logic processor;
• wherein the logic processor is programmed to:
• determine whether an electronic representation of a flow state is in either a primary-water-flow-mode or a continuous-water-flow mode;
• receive input from the first sensor indicating the presence of an object within the first sensor zone and, in response thereto, cause the spout to direct water flow while the input from the first sensor indicates than an object is present in the first sensor zone;
• cause the spout to stop directing water flow when the input from the first sensor indicates that no object is present within the first sensor zone, if it is determined that the electronic representation of the flow state is in the primary-water-flow-mode;
• and
• receive input from the second sensor indicating the presence of an object within the second sensor zone and, in response thereto, if the electronic representation of the flow state is in the primary-water-flow-mode, determine an amount of time for continuous water flow based on the amount of substantially uninterrupted time in which the object is detected in the second sensor zone and in response thereto, change the electronic representation of the flow state from the primary-water-flow-mode to the continuous-water-flow-mode, and cause the spout to direct water flow for the determined amount of time for continuous water flow, regardless of whether an object is present in the first sensor zone.
