Abstract: The antimicrobial toilet includes one or more pairs of electrodes positioned below a water line when the hydraulic circuit is at equilibrium. The pairs of electrodes may be connected to a power source by electrical wires. In some embodiments, the electrodes are positioned on the inner wall of the toilet bowl and in some embodiments, the electrodes are positioned within the siphon tube. In some embodiments, the electrodes are metal strips and in others they are circular. When actuated, an electrical current passes through the toilet water between the electrode pairs resulting in disinfected water. Some embodiments include a pump and water conduit which transfers disinfected water to areas above the water line and emits the water to wash areas of the toilet.

Abstract: The pressure pad which pressure-sensing fabric which is within a gasket and which measures the distribution of pressure on the gasket. Thus, the gasket protects the pressure-sensing fabric from damage due to water or mechanical trauma. The pressure pad includes multiple piezoresistive depositions of piezoresistive depositions ink or paste which act as individual pressure-sensing points. Conductive tracks between the piezoresistive depositions transmit the pressure measurements in the form of electrical signals. The pressure-sensing fabric is connected to a controller and transmits pressure measurements to the controller. Algorithms stored on the controller create a map of absolute mechanical loading to each pressure-sensing point of the pressure pad. The gasket may be mounted beneath a toilet or between plumbing joints. The pressure pad may detect weaknesses in the gasket, a toilet user's weight, a weight of excrement added to the toilet, or a toilet user's posture.

Abstract: The method uses a device which measures the volatile organic compounds (VOCs) present in headspaces of fluid samples to differentiate between authentic and synthetic urine samples. The method includes the use of a device which includes an array of resistive microchemical sensors. The device may be exposed to samples of synthetic and authentic urine to identify a pattern of VOCs in each, these steps being referred to herein as training the device. The device may then be exposed to a urine sample of unknown authenticity and a pattern of VOCs identified. The pattern of VOCs from the urine sample of unknown authenticity may be compared to those of synthetic and authentic urine. In some embodiments the device is installed in a toilet. The method may be used to identify a false sample provided for a urine analysis intended to screen for use of illicit drugs.

Abstract: A user-identifying adjustable footstool that is capable of identifying individual users and automatically adjusting based on user-identification. The footstool can save preferences for different users, such as specific heights or angles. These preferences are called when a user is successfully identified by the footstool. The user-identifying adjustable footstool is particularly useful in conjunction with a toilet, to allow users to achieve individualized squatting positions while using traditional western toilets.

Abstract: The present invention is directed to a toilet that includes a liquid level sensor on the surface of a flush jet fill tube. The liquid level sensor is a noncontact electrical impedance sensor that is an electrical capacitor. The capacitor may be used alone or with other volume sensors to detect volume of materials added to a toilet bowl. Some embodiments include a processor which records data and provides reports that may be clinically useful to assess the user's health status. The temporal nature of the liquid level sensor measurements is particularly useful because urination or defecation may be measured over time. Not only are total volumes detected but rates at which waste is deposited into the toilet during the entire excretion event are detected. These measurements are particularly useful in assessing certain health conditions.
