A system for preventing overflow of a toilet includes a sensor, a processor and an actuator. The sensor senses a parameter caused by fluid dynamics within the toilet during a flush cycle. The parameter may involve vibration, sound, pressure, fluid flow rate or other detectible characteristics of the toilet. The processor uses information regarding the parameter that is gathered by the sensor to evaluate the condition of the flush cycle to determine if an impeded flush condition exists. In the event of an impeded flush condition, the processor directs the actuator to close a valve, which may be the toilet flapper valve in some embodiments. Also disclosed are methods for preventing toilet overflow, detecting an impeded flush condition and calibrating the system.

The disclosure relates to a portable waste collection and sanitation system designed to handle liquid and solid waste, and while conserving water and minimizing odors. The sanitation system is also designed with modular components adapted for in-home installation, where the system can be quickly disassembled and relocated as needed, such as for moving the components to a new location based on environmental conditions.

A method of flushing a toilet that includes opening a first valve to introduce a first supply of grey water into a passage to prime a siphon; opening a second valve to introduce a second supply of water into a bowl from a tank, the bowl having an outlet that is in fluid communication with an inlet of the passage; closing the first valve to shut off the first supply of water; evacuating the contents of the bowl through an outlet of the passage by way of the siphon generated by the introduction of the first supply of water and the introduction of the second supply of water; and closing the second valve to shut off the second supply of water.

Toilet like device, which saves water through the separation of solid and liquid depositions, in a hygienic, comfortable, simple, autonomous and aesthetic manner. It's composed by a main toilet body, which has an open space within itself, connected to the main toilet bowl, a space which is open in its front and superior sides. This space works as a water and urine recipient, the water and urine come from the urinal, which at the same time works as a drainage for urine and water. This space also works as a liquid recipient when the urinal is in vertical position, since it is very likely that, after a liquid deposition, the urinal needs to be raised towards a vertical position, for various different reasons. Any liquid remaining in the urinal falls into this space, without going into the rest toilet body, and much less onto the user.

A method and installation for handling medical waste, which is collected in a receptacle, includes a vacuum waste system (V), whereby medical waste is collected in the receptacle, medical waste is discharged from the receptacle into a waste fixture connected to a vacuum waste piping (13) of the vacuum waste system (V). The discharge sequence of the vacuum waste system discharges the medical waste from the waste fixture or the vacuum waste piping (13) of the vacuum waste system (V) to a waste collecting unit (20) of the vacuum waste system.
