  • 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.

    Abstract: The present invention relates to a device for housing a dye tablet that is capable of acting as a visual warning device to liquid overflow in liquid containers, particularly toilet cisterns. The device may be affixed to the overflow pipe by means of a clip attachment or through integration with the overflow pipe upon creation. The device contains apertures to allow liquid to enter the compartment housing the dye tablet whereby the dye particles become immersed in the liquid. The highly colourised liquid is highly noticeable as it exits the overflow pipe and thus gives warning of a system malfunction.

  • 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.

  • 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.

  • Patent number: 4333184
    Abstract: This invention, is a multi-function closet stool, which can really serve the purpose of automatic timing, measuring pressure, flushing and saving water. When one sits on the seat of closet stool, the driving piece pulls the driving steel cable to make timing and piston assembly simultaneously actuate and control arm sandwich on top of a movable piece in the sleeve. When one discharges his urine and stands up, the rear part of seat of closet stool will rebound promptly by the spring; meanwhile, the timing unit begins to count time, then, the driving arm makes the control arm release the movable piece in the sleeve by means of the pulling of timing unit and move upwards by the elasticity of spring. A rubber ring compresses air in the sleeve, the high velocity air will instantly rush in air container through a hole passage, pipe joint, filter and pipe. The air will open a movable lid for the purpose of water-flushing.
