Abstract: A toilet for measuring excreta is disclosed. The toilet is adapted to measure the amount of excreta received by the bowl and then the flush water. A pressure sensor is configured to monitor the pressure exerted by the flush water and any excreta contained therein. Data from monitoring the pressure of the flush water and excreta therein is used to determine the weight or volume of the excreta received by the bowl. This toilet can provide data which may be used to analyze how the volume of flush water changed due to excreta deposit. A volume change feature can be associated with a urination event and the data associated with the event can be used to determine a urine characteristic of the event.

Abstract: We disclose a device and method for collecting a urine sample as a user urinates into a toilet. The device further conducts analytical measurements which may include spectral, colorimetric, and chemical assays. The user need only urinate normally into the toilet. A urine collection trap, which includes a vertical slit, may capture a urine sample which has a volume in the microliter range. Pumps may divert the urine from the vertical slit into a conduit that is connected to spectral analysis devices and other devices for analyzing the urine sample. The disclosed device is both convenient and prevents unsanitary urine spills.

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.
