  • Patent number: 10214889
    Abstract: An in-toilet leak detector is disclosed, as are communication systems for reporting toilet leaks. The leak detector comprises an inlet that receives water from the toilet's fill tube and diverts it through a flow tube. A capacitive sensor is located between the inlet and an opening of the flow tube from which water flows into the overflow tube of the toilet tank. A housing is connected to the flow tube and the inlet and contains a controller and other electronics, including one or more transceivers. The leak detector measures the duration of water flow and establishes an alert if the water flow is shorter or longer in duration than a calibrated normal duration. The transceivers connect the leak detector to a computer network, and leak alerts are communicated to a server or servers so that they can be forwarded directly to those responsible for fixing the toilets.

  • Patent number: 10206548
    Abstract: An antimicrobial toilet includes an inner surface of a toilet bowl which includes a non-doped titanium dioxide coating. The titanium dioxide coating is photocatalytic and antimicrobial in the presence of ultraviolet (UV) light. In the absence of UV light, the inner surface of the toilet bowl is not antimicrobial. The UV light source may be actuated after the waste has exited the toilet bowl. Consequently, the waste may be used in digesters used to produce clean energy or for analysis to assess the user's health status without being exposed to the antimicrobial properties of the titanium dioxide coating. The UV light may then be actuated to disinfect the toilet bowl. The outer shell of the toilet is coated with a doped titanium dioxide. The doped titanium dioxide is photocatalytic and antimicrobial in the presence of visible light. The outer shell is antimicrobial when standard room lights are actuated.
