Where the main body plate portion is stepped on by a foot, the plurality of partition walls are positioned inside of a contour of the foot.

Example lavatory waste tube connection systems and related methods are discoed herein. An example apparatus includes an extension tube to be coupled to a system waste tube and a junction box to be coupled to a surface of a vehicle lavatory. The junction box is to define a housing for the extension tube.

Embodiments disclosed herein are directed towards noise reduction pipes, vacuum-assisted toilet systems including the same, and methods of using the same. An example noise reduction pipe includes a first end and a second end that is opposite the first end. The first end is configured to be coupled to an outlet of a toilet bowl and the second end is configured to be coupled to an inlet of a flush valve. The noise reduction pipe defines a fluid flow path that extends between the first end and the second end such that waste may flow from the first end to the second end. The noise reduction pipe also includes one or more bends. Each of the bends exhibits a radius of curvature that is greater than about 5 cm or a length that is greater than about 30 cm.

The embodiments disclosed herein are directed towards vacuum-assisted toilet systems and methods of using the vacuum-assisted toilet systems. An example vacuum-assisted toilet system includes a toilet bowl defining an outlet and a flush valve fluidly coupled to the outlet. The vacuum-assisted toilet system also includes at least one water source fluidly coupled to the toilet bowl. The water source is configured to supply water to the toilet bowl. The vacuum-assisted toilet system also includes at least one water actuator coupled to the water source. The water actuator is configured to control the amount of water that is supplied by the water source to the toilet bowl. The vacuum-assisted toilet system also includes a controller that is configured to at least partially control the operation of one or more components of the vacuum-assisted toilet system, such as at least one of the flush valve or the water actuator.

An enhanced abandoned call recovery (“E-ACR”) process allows certain abandoned calls to be eligible for a callback call. An E-ACR assignment point defines which abandoned calls in an inbound campaign or interactive voice response (“IVR”) menu are eligible to be processed to determine whether the E-ACR callback should occur. The determination of whether a callback occurs involves various compliance tests, such as ensuring calling window, call attempts, and other regulatory concerns are addressed. Once a callback is determined to occur, it is associated with a specific campaign to ensure the called party is provided with agents having the skill set as defined for that assignment point. In this manner, only eligible callers receive an E-ACR callback, and further receive the callback in a compliant manner and handled by the same skill set of agents as would have been allocated to the caller had they not abandoned their call.

A vacuum wastewater device (100) having a wastewater collection container (102) in the form of a vacuum toilet, a vacuum wastewater fitting (202), a wastewater valve (204), which is connected between the wastewater collection container (102) and the vacuum wastewater fitting (202); at least one electrical final control element (206a, 206b, 208), which is configured to change an actual state of the vacuum wastewater device (100), and a control unit (106), which is configured to receive a message (902) according to a network communication protocol, wherein the message (902) includes a specification on a target state; and to activate the at least one electrical final control element (206a, 206b, 208) according to the target state.

An accumulator assembly having a wastewater retention tank defining an interior chamber. A fluid level sensor is coupled to the waste retention tank and configured to sense a level of liquid in the chamber. An extraction pipe extends into the chamber and is coupled to an extraction valve. Coupled to the fluid sensor is a controller that is also coupled to the fluid level sensor and to the extraction valve. The controller is configured to open the extraction valve upon receipt of a signal from the sensor. The accumulator assembly also includes an odor mitigation subassembly in fluid communication with the chamber. The odor mitigation subassembly further includes an air displacement port, an odor filter and an overflow prevention device, the overflow prevention device being in fluid communication with the chamber and located downstream of the air displacement port and upstream of the filter.

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.

Provided is an automatic excretion disposal device (1) which is configured to automatically perform an excretion disposal of a person (P) to be cared, the device including: a cup (2) which is attached to a body of the person to be cared to receive excretion; a detection unit (3) which is configured to detect excretion in the cup; a feed water pipe which is configured to decompress cleaning water from a water supply (W) to a predetermined pressure and directly supplies the cleaning water, on the basis of detection result of the detection unit; a suction motor (30) which is configured to suck sewage generated when the body and inside of the cup are cleaned with the cleaning water supplied from the feed water pipe (R1), and to discharge the sewage to outside of the cup; a tank (10) which is configured to temporarily store the drainage sucked by the suction motor; and a drainage pump (20) which is configured to cause the drainage to forcibly flow out to a drainage piping connected to a sewer or a septic tank, while pulverizing solid matters contained in drainage in which the sewage stored in the tank is mixed with the cleaning water directly supplied from the feed water pipe.

A waste drain system is configured to be coupled to a toilet. The waste drain system includes a conduit including a main body defining an internal passage having a central longitudinal axis, and one or more cutting blades extending from the main body toward the central longitudinal axis. The one or more cutting blades are configured to cut one or more items that pass through the internal passage.
