摘要： A toilet apparatus according to an embodiment includes a human body detector and a controlled part. The toilet apparatus is mounted to a toilet. The human body detector radiates a radio wave and detects a human body based on the signal that is obtained. The human body detector outputs a control signal based on the detection result. The controlled part is controlled based on the control signal. The human body detector has two or more establishment times from when the signal is obtained until when the detection result based on the signal is established.

摘要： A flush valve system is provided having an inlet and an outlet, and a main valve element adapted for transition between a closed position and an open position is disclosed. The flush valve further includes a control chamber in communication with the inlet, and a vent outlet in communication with the outlet. The system includes a solenoid for establishing communication between the control chamber and the vent outlet to establish a pressure differential across a portion of the main valve element. The system also includes a power supply for energizing the solenoid, a deployable actuator in communication with the power supply, and a microprocessor in electrical communication with the main valve element. The microprocessor is adapted to determine a valve opening time, calculate fluid pressure based on the valve opening time, and deliver a predetermined quantity of fluid through the valve based on fluid pressure.

摘要： A toilet system with a toilet base including a toilet bowl and a shroud for covering a plumbing riser located at a rear end of the toilet base that provides ligature-resistance for institutional applications. The shroud has a mating feature that joins with a corresponding feature at a rear portion of the toilet base to prevent formation of a gap between the base and a front of shroud in at least at a top side of the area of contact between the shroud and the back of the toilet base. The mating feature can be provided by forming a rectangular cross-section at the rear of the toilet base and providing a matching aperture through the shroud. A toilet seat, which may be bonded or bolted to toilet base has an outer edge that is chamfered to prevent ligature formation around a portion of toilet seat.

摘要： A human body detection sensor includes: a detection decision unit that decides whether a state is a detection state or a non-detection state of a detection target; a specular reflection decision unit that decides whether or not reflected light that is incident onto a line sensor is specularly-reflected light; and a continuation decision unit that decides whether or not a state in which the detection target exists is ongoing, wherein, when specularly-reflected light is detected while a determination is made indicating the detection state, the detection decision unit keeps the result of a determination indicating the detection state without change if the result of the decision by the continuation decision unit indicates that the state is ongoing and changes the determination to a determination indicating the non-detection state if the result of the decision shows any other states.

摘要： Various systems and methods of controlling the flow of water from a fill valve in a toilet tank to a toilet bowl of a toilet using a bowl fill valve are provided. An inlet of the bowl fill valve is coupled to a bowl fill outlet of the fill valve and the outlet of the bowl fill valve is channeled to the toilet bowl. In illustrative embodiment, a method is provided comprising the steps of determining when the toilet tank has been substantially drained of water during a flush cycle, and opening the bowl fill valve for a predefined period of time after the toilet tank has been substantially drained of water to fill the toilet bowl of the toilet with water. The predefined period of time is less than a total time of the flush cycle.

摘要： The smaller volumes of water currently required to flush toilets and urinals may be insufficient to clear the fixtures and the drainage lines to which they are connected of waste and other undesirable materials, which can build up over a period of flushes or non-use. A flush valve control device programmed or otherwise configured to provide a selectable, periodic heavier flush volume of water after a predetermined number of low volume flushes and/or after a predetermined period of inactivity of the toilet or urinal can provide for sufficient drainage line carry-out of waste and prevent undesirable buildup of minerals, etc. on the inside surfaces of the fixtures and drainage pipes.
