    摘要： A fluid delivery device including an electronic faucet having a plurality of faucet components, and a primary capacitive sensor coupled to at least one of the faucet components and providing a primary output signal. At least one secondary capacitive sensor is located on or near an item which causes unintended effects on the output signal from the primary capacitive sensor and provides a secondary output signal. A controller determines a difference signal between the primary and secondary output signals of the primary and secondary capacitive sensors to control operation of the electronic faucet.

    摘要： A faucet (10) includes a spout (12), a passageway that conducts fluid flow through the spout (12), a electrically operable valve (22) located within the passageway, a manual valve (20) located within the passageway in series with the electrically operable valve, and a manual handle (14) that controls the manual valve (20). The faucet (10) also includes a first touch sensor (26) on the manual valve handle (14), a second touch sensor (28) on the spout (12), a capacitive sensor (30) directly coupled to one of the first and second touch sensors (26, 28) and capacitively coupled to the other of the first and second touch sensors (26, 28), and a controller (24) coupled to the capacitive sensor (30). The controller (24) is configured to monitor the output signal from the capacitive sensor (30) and to distinguish between a user tapping one of the spout (12) and the manual valve handle (14), a user grabbing the spout (12), and a user grabbing the manual valve handle (14). The controller (24) is also coupled to the electrically operable valve (22) to control the electrically operable valve (22) is response to the output signal from the capacitive sensor (30).

    摘要： An electronic faucet comprises a spout having a passageway configured to conduct fluid flow through the spout, an electrically operable valve coupled to the passageway, and a single capacitive sensor coupled to a portion of the faucet. The single capacitive sensor provides both a touch sensor and a proximity sensor for the electronic faucet.
