  • 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: 10064582
    Abstract: This document describes assessment of human physiological systems. Various noninvasive sensors can be used to detect vitals and other parameters and combined with mathematical models to assess the functional state of physiological systems. Conventional techniques can use invasive sensors to monitor cardiac pressures and volumes, along with pressure transit to quantify cardiovascular health. While known to be effective these invasive techniques often require surgery and are resource intensive limiting their use to cases where the risks and costs are of clear immediate benefit. In contrast, noninvasive health monitors present little if any risk and are easy to use. Further, the techniques described herein can determine trends in a person's cardiovascular health. With these trends, a person can know if the effort they expend to improve heart health actually makes a difference. Further, negative trends can be found that can spur people to improve their health or get medical attention.

  • Patent number: 8510875
    Abstract: An indicator that the cartridge is draining slowly is placed on top of the cartridge. When slow draining causes urine to pool on top of the cartridge, liquid enters a float housing, causing an indicator to change color. The indicator is visible through a lens in a diverter. The indicator may be a disk that undergoes a chemical reaction to change color or a float that flips over to reveal a side having a different color. When the cartridge is operating properly, the float displays a first color. Flipping of the float reveals a second color to the observer. A color change indicates, such as by signaling, that the cartridge needs to be replaced.

    Abstract: A five-second leak detection technique is used to test for invisible leaks in toilets and similar fixtures. Because of its speed it is particularly useful for large apartment complexes, condominiums and hotels where it is desirable to check hundreds of toilets in a short time. It's clear-cut results and high visibility make it ideal for home use as it unequivocally identifies seeps and slow leaks that may be undetectable otherwise. Checking is done by applying a swath of liquid with a high color density across the porcelain surface just below the rim drain holes in the toilet. If the a toilet is leaking, tiny rivulets of water draining from these holes will immediately cause white streaks in the dense colored swath, alerting the operator to the presence of a leak.

    Abstract: A toilet tank flush valve for use in the demand mode, and which includes a discharge control and closure valve for controlling the flow of water from the tank or reservoir to the bowl, and with the valve further having a generally cylindrical configuration with an open top and a closed bottom defining a water retaining chamber, with the chamber extending upwardly above the discharge drain opening and being designed to retain a fill of a certain first quantity of water. Pivotal opening of the valve, while tipping a portion of the water outwardly of the enclosure, will not discharge more than about 70% of the volume of water retained within the enclosure so as to permit a more positive seal of the valve onto the discharge drain opening.

  • Patent number: 5384917
    Abstract: A new and improved child's auxiliary toilet seat for a toilet includes a hinge pin assembly which includes a hinge pin and first hinge members connected to the toilet for receiving the hinge pin. A first toilet seat assembly has a large aperture for adults. A second toilet seat assembly includes a narrower aperture for children. The second seat portion includes a portion proximal to the water tank and a portion distal to the water tank. The second seat portion further includes a first side portion and a second side portion that extend between the proximal portion and the distal portion. The respective first side portion and the second side portion include respective leg supporting extension members which project toward each other from the respective first and second side portions, thereby narrowing the aperture for the children's use. A toilet seat cover covers the toilet seat assemblies.

  • Patent number: 5198192
    Abstract: A urine detection device is disposed to a urine receiving surface of a toilet stool in which urine, diluting water and reagent are mixed by vertically moving a piston in the cylinder of the detection device, the reaction between them is detected by an electrode and the ingredient in urine is detected. Liquid in the cylinder is stirred by a stirring device to blown air into the reagent reservoir, by which oxygen is dissolved in the reagent. Cleaning liquid is sprayed from the nozzle to the electrode for flushing. An opening is disposed to a supporting wall of the toilet stool, through which the cylinder is detached or attached. The electrode is disposed such that its rear end is directed to the opening and detached or attached through the opening.

  • Patent number: 5148701
    Abstract: Water testing apparatuses and methods for detecting contaminants in water supplies, such as from wells or other domestic water sources. The apparatuses are for use in reservoirs, such as a water closet of a sanitary toilet. They include an enclosure which defines an interior chamber which is intermittently charged with water. The water charged to the interior chamber is passed through one or more filters, preferably a packed column, which removes or otherwise indicates the presence of contaminants in the water. A counter measures the water passed through the system. Water is discharged from the interior chamber using a siphon. The siphon and restriction of flow caused by the filters help control the direction of flow and substantially prevent backflow. The summit of the siphon includes a relief valve for venting gas during filling of the siphon discharge.

  • Patent number: 5144700
    Abstract: A water monitor for a toilet flush tank includes a sensing system and an alarm system. The sensing system includes a tube having a constricted aperture in the base. The tube is normally filled with water. When the flush tank is emptied water begins to drain slowly from the tube. A float in the control tube responds to the water level in the tube. A contact attached to the float closes contacts on the control tube if the flush tank does not refill. The closing of the contact is used to trigger an alarm signal. The monitor includes a self cleaning drainage aperture for the control tube and a flexible mounting belt which provides for simple mounting and adjustment.

  • Patent number: 5014368
    Abstract: The invention is directed to a method and apparatus for monitoring liquids ischarged intermittently from a discharge receptacle having a siphon. The liquids originate in a facility in which personnel work with open radioactive substances. Measurements are made of the radioactive charge of discharged liquids in the region of the siphon of each discharge receptacle to prevent contamination of the discharge path into the drainage system. If a radioactive limit value of radiation is detected which is above a specific threshold, discharge of the liquid into the drainage network is prevented. The discharge receptacles are then emptied individually and upwardly.
