Systems and methods for improving hand hygiene compliance
A method and apparatus that systematically prompts staff, patients and visitors at care facilities to perform handwashing at critical time periods, for example after touching a toilet flush handle or upon entering or leaving a patient's room. A plurality of detectors are used to sense whether a person has entered an area and to determine whether the person has cleansed their hands within a predetermined period of time before entering the area or leaving the area. If it is determined that the person has cleansed their hands within the predetermined period of time, no prompting message is generated. If it is determined that the person has not cleansed their hands within the predetermined period of time, an audio / visual warning message is generated.

Two-stage flush and grey water flush systems and devices
ActiveUS20130305444A1Reduce noise levelLess vacuumFlushing devicesLavatory sanitoryNoise levelToilet flushing
Embodiments of the present invention provide a grey water flush system for use with vacuum toilets. One embodiment of the system provides a two-stage flush that uses a transient tank in between the toilet bowl and the main aircraft waste tank, which reduces the noise level associated with the flush process because a lesser vacuum is demanded for the first stage of the flush. Embodiments of the system further capture grey water from a sink basin in a reservoir and use that water in the toilet flush process. There is further provided a lavatory odor removal system option that is activated during the second stage of the flush.

Waterless vacuum toilet system for aircraft
InactiveUS20040010843A1Reduces and eliminates adhesionIncrease surface areaWater closetsDispersed particle filtrationWaste collectionEngineering
A waterless vacuum toilet system for an aircraft includes a toilet bowl connected via a suction valve and a waste collection pipe to a waste collection tank. Waste-contacting surfaces that come into contact with urine and fecal waste are coated with an adhesion-inhibiting or adhesion-reducing nanocoating. The adhesion of waste is significantly reduced, and the need for flushing water is completely eliminated. Instead, an air jet arrangement preferably including an annular ring nozzle or annular air gap directs an airflow into the toilet bowl and along the nanocoated waste-contacting surface thereof, to "air flush" the waste material from these surfaces. The flushing airflow may be induced through the air jet arrangement into the toilet bowl by the suction applied through the suction valve. The "air flushed" toilet system substantially reduces the total system weight and eliminates the need for toilet flushing water to be carried in the aircraft.

Toilet seat lifter with flusher
A mechanism for raising and lowering a toilet seat in response to actuation of foot pedals. An actuation cylinder with a contained piston is connected between the toilet bowl and the toilet seat. Water from the supply line for the toilet is routed to the actuator cylinder when a seat up pedal is depressed and causes the piston to extend out of the actuation cylinder and raise the seat. Operation of a flush pedal causes the water within the actuation cylinder to drain so that the toilet seat lowers. A mechanical linkage from the flush pedal to the flush mechanism of the toilet links toilet flushing to the seat lowering action, ensuring that the seat is lowered after each flush.

Integrated domestic utility system
InactiveUS20090222981A1Solar heating energyGeneral water supply conservationEngineeringToilet flushing
An integrated domestic utility system is used to recycle grey water in a domestic house as a means to divert treated potable water away from non-potable uses, and in particular, toilet flushing. The system comprises a rainwater tank for storing rainwater collected from a roof top and a grey water tank to store grey water collected from a shower or bathtub. The rainwater is used to augment the grey water supply through a self regulating valve. Domestic water can also be used to replenish the grey water tank. A demand amount of grey water is pumped from the storage tank to at least one toilet tank. The system is controlled by a controller using pressure sensors and temperature sensors. The invention may include a solar heating circuit coupled to a domestic water heater. In one example of the invention, the system stores grey water in a bathtub and supplies it to toilet tank.

Toilet rim mounted liquid dispenser using vertical wicking system
A device for dispensing liquids from under the rim of a toilet bowl is disclosed. The dispensing device includes a reservoir for holding a liquid, a wick, and means for suspending the reservoir from the toilet bowl rim. The wick transports the liquid upward from the reservoir to a position at or above an upper surface of the reservoir. During a toilet flush, flush water washes liquid on the upper surface of the reservoir and / or liquid on the wick into the toilet bowl. The wick is formed from a hydrophobic material in order to repel flush water so that flush water does not travel down the side of the wick and dilute the liquid in the reservoir with flush water. In another aspect, the suspension means and / or the entire device is not visible from above the rim of the toilet bowl when the dispensing device is installed on the rim.
