A rinse ring system for use on a toilet. The rinse ring is a dual channel rinse ring, which allows the toilet to be flushed with either potable water from a fresh water system or with grey water from a grey water source. Other flush fluids are possible for use. The dual channel rinse ring provides separation between entry points for potable water rinse and the grey water rinse, preventing the possibility of contamination of the potable water source with grey water.

Dual channel rinse ring system for toilet

Methods and systems for equipping a toilet with hygiene and safety features by controlling and reducing potential escape of liquid waste from the toilet.

Vehicle toilet with improved sanitation and security features

A disinfection system for treating water. In a specific example, the system treats water prior to its upload to an aircraft or other passenger transportation vehicle. One or more replaceable filters are positioned within a filter chamber housing in order to expose water flowing through the system to filtration treatment.

Portable potable water filtration

A method for in-situ data acquisition comprises providing a mold, wherein at least a portion of the mold is transparent, inserting a liquid composite molding reinforcement into a cavity of the mold, injecting a fluid into the cavity of the mold, the fluid comprising a fluorescent dye, lighting the mold with an ultraviolet lighting source and capturing a plurality of images of a front portion of the fluid as the fluid advances within the cavity of the mold. Capturing the plurality of images of a front portion of the fluid may include advancing a camera along a camera track as the fluid advances within the cavity of the mold. A corresponding method and computer program product for processing images captured by the above method are also disclosed herein.

Data acquisition for liquid composite molding

An ultraviolet (UV) light disinfection system for treating water prior to its delivery to a water usage device. One or more UV light emitting diodes (LEDs) are positioned within a water system floor interface in order to expose water flowing through the system to germicidal light treatment.

Water system floor interface with ultraviolet light treatment

Embodiments of the present disclosure relate generally to a liquid level sensor system that allows ease of connection and disconnection of a removable vessel (such as a toilet bowl) from a stationary unit (such as a toilet frame). The system provides at least one liquid level sensor (a first part of the sensor probe connection) mounted to the removable vessel, a liquid level sensor circuit board mounted to the unit, and a connection feature (a second part of a sensor probe connection) configured to extend between the sensor and the circuit board. When the removable vessel is removed from the vessel, the sensor probe connection is disconnected without the need for manual intervention. Installation of multiple probes and varying their location can support detection of a single or several discrete levels, or provide for any required redundancy of detection.

Disclosed are systems and methods of managing grey water or other recycled water onboard an aircraft based on demand within the aircraft. In some cases, the grey water is obtained from a lavatory or galley sink of the aircraft and is treated to purify and/or filter the grey water. The treated grey water can be routed within the aircraft according to a control scheme that accounts for demand within the aircraft. For example, some or all of the treated water may undergo electrolysis to produce oxygen gas (O2) and hydrogen gas (H2), some or all of which may be fed into the fuel cell system and used in a chemical reaction to produce electrical energy and other fuel cell by-products that can be directed to various aircraft systems and/or the aircraft cabin/lavatories.

Embodiments of the present disclosure relate generally to systems and methods for reducing sound in vacuum toilets. In one example, multiple rinse injections are used at appropriately timed intervals in order to reduce the vacuum flush sound levels.

Multiple rinse injections to reduce sound in vacuum toilets

Embodiments of the present disclosure relate generally to a reservoir () that is easily removed from a grey water flush system. The reservoir is made modular so that rather than removing an entire reservoir/pump/circuitry system, the reservoir () can be separately removed from the system. The reservoir can also be made disposable, which can save cleaning and refurbishment costs. This can also increase turn-around time for maintenance of the system.

Disposable modular reservoir

Embodiments of the present invention provide systems and methods for disposal of liquid and food into a sink basin. The disclosed system cooperates with and delivers the received waste material to the main waste system on-board the vehicle. This is typically an aircraft waste tank. The system does not require a manual flush, but includes a sensor system that activates drainage of the holding line when the liquid and/or other waste material reaches a certain level therein. The disclosed system combines the functionalities of a common galley sink and a galley waste disposal unit, but occupies only the space envelope of an existing galley sink. The use of an existing galley sink means that no additional space on the countertop is required.

Integrated sink and disposal unit

Systems and methods for treating and disinfecting water contained in a potable water tank. The systems and methods generally use one or more UV LEDs that are positioned along various portions of the water tank and that are configured to emit UV light/irradiation into the water contained therein.

UV water treatment in portable water tank

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.

Two-stage flush and grey water flush systems and devices

Embodiments of the present invention provide a water management system for use on board a passenger transport vehicle. The water management system may be used to address and manage excess humidity, water leaks, or any other instance when water or other liquid may collect at a certain location. The disclosure provides a system for managing excess water and for optionally delivering the water to another location. The removal location may be a disposal outlet or it may be a beneficial use of the collected water on-board the vehicle.
