Abstract: A lavatory drain system is disclosed. The basin, containing a U-shaped drain channel, employs one of two draining embodiments. In the first, a drain plate divides the drain channel into two chambers, allowing for fluid communication between them through openings in the drain plate. In another embodiment, the drain channel forms the upper chamber while a pipe disposed below the channel serves as a lower chamber for fluid to flow to the drain. Further, the drain cap of the claimed system is configured to direct air about the basin. One embodiment utilizes a ridge protruding over one of the basin's sides to captures air and directs it to a return duct. In the other embodiment, a series of louvres located in an opening are used to filter water and debris from the air before it returns to the fan.

Abstract: Systems and methods for a multi-function lavatory fixture are disclosed. The lavatory fixture includes a first and second leg, where a first end of each leg is configured to be mounted to a deck and a second end of each leg is located over a basin of the lavatory fixture. A connecting section extends between the second ends of each leg and includes outlets to dispense water, soap, and air to wash a user's hands. The fixture also includes indicators located proximate each of the outlets to indicate to the user the location of each outlet. A sensor located near each outlet identifies the presence of a user's hands near the outlet and dispenses water, soap, or air accordingly. A controller within the lavatory fixture receives inputs from each sensor and activates the appropriate pump, fan, valve, and the like to deliver the desired product at the appropriate outlet.

Abstract: A lavatory system including a countertop and a first hand washing station is provided. The first hand washing station includes a basin supported by the countertop and a faucet supported by the countertop. The lavatory system also includes a hand dryer including a housing supported by the countertop. The housing defines a cavity in which a user's hands are inserted during drying, and a motor configured to generate blown air which is supplied to the cavity. The housing is located such that the user's hands may be inserted into the cavity without the user leaving the first hand washing station.

Abstract: A capacitive sensing system and method for a hand washing lavatory system is disclosed. The lavatory system comprises a receptacle defining a hand washing area, a fixture configured to deliver water to the receptacle, and a capacitive sensing system configured to detect the presence of a user and actuate the fixture. The capacitive sensing system comprises a first sense electrode coupled to the receptacle and configured to measure a first capacitive value, a second sense electrode coupled to the receptacle spaced apart from the first sense electrode and configured to measure a second capacitive value, and a circuit configured to control operation of the fixture in response to a change in the first capacitive value relative to the second capacitive value.
