A flush toilet includes a bowl, a tank coupled to the bowl, a flush valve positioned within the tank, and a flush device configured to initiate a flush cycle. The automatic toilet further comprises an electronic sensing assembly having a sensing member positioned on the bowl for detecting an overflow condition of the bowl, an overflow device operably coupled to the flush device, and a controller in electronic communication with the electronic sensing assembly and the overflow device for controlling the flush device in response to a condition of the toilet.

A universal fluid flow sensor system and method installable in a toilet tank. A system is disclosed that includes a housing that contains a power source and an event processing system; a flow sensor coupled to a base of the housing, wherein the flow sensor provides flow rate data to the event processing system, the flow sensor having an inlet adapted to receive an inflow of water from a fill tube and an outlet adapted to expel an outflow; a universal stem that extends from the housing and includes at least two different mounting systems adapted to seat the housing onto different overflow tube types, wherein the universal stem includes an elbow assembly configured to receive and redirect the outflow into an overflow tube; and a pair of cylindrical probes positioned in parallel within the elbow assembly, wherein the probes activate the event processing system in response to a detection of water contacting the probes.

A toilet monitor uses a toilet tank water level sensor producing a toilet tank water level measurement signal. A processor detects rate of change of the measurement signal and conditionally produce a responsive actuation signal in response to the detected rate of change. A transducer connected to receive the actuation signal and transmit information, provide a humanly-perceptible indication, generate a data log and/or control an electronic water supply valve.

A system for optimizing a timing of a flush valve is provided. The system includes a flush valve comprising a flow area and a solenoid configured to open the flush valve, at least one pressure sensor configured to measure a pressure in the flush valve, and at least one controller in communication with the at least one pressure sensor and the solenoid. The at least one controller is programmed or configured to control the solenoid to open the flush valve for a flush time in response to a flush request, measure a pressure in the flush valve to obtain at least one flush valve pressure, adjust the flush time based at least partially on the at least one flush valve pressure, resulting in an adjusted flush time, and control the solenoid to open the flush valve for the adjusted flush time in response to a flush request.

Water and space saving bathroom components especially useful for a comfort station. Included are a novel toilet having a cistern with a sink in combination with the toilet, a novel waterless urinal and a hand sanitizer dispensing station. The sink is an integrally formed sink into the top of the cistern and has a drain formed into the sink for draining effluent from the sink into the toilet cistern. A faucet is installed in the surface of the sink to provide a clean water source for hand washing and the like that generates grey water after washing. The waterless urinal can be plumbed and mounted to a comfort station wall or on a mobile stand, while the hand sanitizer dispensing station may be adapted for multiple dispensers. The dispensers may be mounted at different heights to accommodate adults, children and disabled persons in wheelchairs.

There is provided a flush toilet that cleans a bowl using a swirl flow formed by cleaning water flowing down from a slit aperture formed on a rim. The flush toilet has a discharge passage an inlet of which is connected to a lower portion of a waste receiving having a bowl shape, and an inlet of an inlet conduit of the discharge passage is formed such that on a horizontal cross-section plane a maximum width of a front portion in a left-right direction is larger than a maximum width of a rear portion in the left-right direction.
