The sensor platform may be mounted on a support panel. The support panel may be mounted on a toilet lid. The one or more sensor platforms may be extendable towards a user seated on the toilet. Each sensor may be independently extended so that it is positioned flush against a user's body. The sensor platform array may include bendable arms which reach around a user and place sensors on the ventral side of the user. The sensors may collect measurements which are relevant to the user's health and well-being. In some embodiments, the sensors may be removable and replaceable so that different sensors may be added according to a user's individual needs.

Abstract: A toilet is disclosed. The toilet has a bowl adapted to receive excreta, a shelf for receiving feces in the bowl, and one or more sensor for detecting a property of the feces.

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 device includes a pressure-sensing pad which measures a load distribution across its surface and a rigid layer which measures total mass. The mass measurement may be used as a ground-truth measurement with which to calibrate the measurements collected by the pressure-sensing pad. Accordingly, a more accurate pressure distribution may be created using calibrated pressure distribution data. The pressure-sensing pad may include an array of sensors which may be in connection with a flexible layer. When pressure is applied to any of the sensors within the array of sensors, the flexible layer may compress and change the capacitance at the sensors on which the pressure is applied. The rigid layer may include strain gauges which measure the total mass on the device. A controller may include instructions for performing calculations to convert the measurements into a pressure map using calibrated measurements of the pressure distribution across the pressure-sensing pad.

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: 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 bidet system may include multiple seat scales which may float between the toilet bowl rim and the toilet seat. These seat scales may collect measurements which are transmitted to a controller. The controller may include instructions to calculate a user's center of mass based on the measurements and to identify the position of the user's anus based on the center of mass. The controller may then transmit instructions to a bidet wand directing direct the bidet wand to a position which aims a cleansing fluid spray toward the user's anus. A camera which collects images of the user's anal and urogenital region may also be included in the bidet system. The camera may transmit obfuscated images to the controller to identify other areas of the user's anatomy in need of cleansing. The controller may direct the bidet wand to aim a cleansing fluid spray toward these areas.

Abstract: The health-monitoring system includes one or more cameras which collect graphic data and a controller which calculates body proportion measurements based on the graphic data. Specifically, the health-monitoring system measures a user's body parts and their relative positions. These measurements may be combined with those collected by other devices and sensors within the system which conduct other health-related measurements. The other devices and sensors may be housed within a container and a least one of the cameras may also be housed within the container. In some embodiments, the container is a fixture, such as a bathroom medicine cabinet . The camera may be invisible to a user as positioned within the fixture. Consequently, the user may move and behave normally without changes which may occur due to being self-conscious of the camera. Calculations may occur within the controller or on a remote server to which data is transmitted.

Abstract: A dryer for use with a bidet is disclosed. In one embodiment, a moveable dryer wand emits an air curtain as the dryer wand moves across the bidet bowl beneath the user after cleansing. We further disclose a dryer which produces a second air current which moves air in a different direction than that emitted by the dryer wand and further controls the movement of excess water remaining on a user after cleansing. A dryer that includes moveable dryer wand used in coordination with a moveable bidet wand are also disclosed and claimed herein.

Abstract: The liquid sample capture apparatus captures a sample of a liquid and holds the sample for optical analysis. The apparatus may include a mount which is traversed by a sample conduit. The mount may have an elongated shape and two ferrules may be placed within the mount along the longitudinal axis of the mount. An end of each of the ferrules may extend into the sample conduit forming a narrowing of the sample conduit which holds the liquid and prevents it from escaping prior to analysis. The opposite ends of the ferrules may each be connected to an optical cable. The optical cables may be connected to an analytical device, for example, a spectrometer. The apparatus may be mounted within a toilet bowl where it may capture and analyze a urine sample.

The force sensors may be positioned in one or more cavities on a bottom side of a substrate material of the thin scale or be embedded within a substrate material. Embodiments of a standalone thin scale and a thin scale with a toilet are disclosed.

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.
