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

Vacuum toilet flush valves. The disclosure uses a precise positioning of a magnet with respect to a flush valve plate in order to identify absolute alignment accurately.

Magnetic position sensor for aircraft toilet flush valve

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

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.

Liquid level sensor with improved removability

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 invention relate generally to multi-port orbital valves for use in controlling the direction of fluids and mixed media, and find particular use in connection with toilet systems, such as vacuum toilet systems.

Multi-port orbital valve

Embodiments of the present invention relate generally to multi-port valves for use in controlling the direction of fluids and mixed media, and find particular use in connection with toilet systems, such as vacuum toilet systems.

Multi-port valve

Embodiments described herein relate to quick release toilet concepts, which can be useful particularly on-board aircraft and other passenger transport vehicles. Further specific embodiments relate to a quick release rinse valve, a quick release flush valve, an integrated rinse ring, a replaceable toilet bowl, an integrated anti-siphon/rinse valve, and improved flush valve performance.

Toilets with improved removability for passenger transport vehicles

Embodiments of the disclosure provide systems and methods for improved removability and ease of maintenance for one or more components of the vacuum toilet system. They can be particularly useful on-board aircraft and other passenger transport vehicles. Specific embodiments relate to a rinse valve bracket and connection system, a rinse ring tie down, and various improved connection systems.

Vacuum toilet assembly

Embodiments described herein relate to quick release toilet concepts, which can be useful particularly on-board aircraft and other passenger transport vehicles. Further embodiments relate to improved shroud components for toilets that help reduce splash. Further embodiments also relate to flushing systems for use with vacuum toilets.
