Abstract: We disclose an in-toilet urinalysis system which includes a system for collection urine and for analysis of urine components using aptamer technology. Urine collection system may dispense urine into cuvettes, channels, or other containers that include aptamers. The aptamers may detect target molecules in urine. The aptamers may measure urine analytes, detect excreted drugs or drug metabolites, or disease markers. Upon binding to the target molecule, the aptamers may produce a signal which a sensor in the toilet may detect. In some embodiments, the signal may be electrochemical, fluorescent, or colorimetric. The measurements obtained from analysis of the urine may be used to assess a user's health or diagnose disease. In some embodiments, the measurements are stored in a controller which may transmit the measurements to a healthcare provider for assessment.

Abstract: We disclose a method of tagging nutritional or drug compositions using chemical entities which are known to be safely consumed and which are detectable using known techniques, including near IR spectroscopy. The chemical entities used as tags may be detected in easily obtainable biological samples, including urine and feces. The biological sample may be deposited into a medical toilet which may analyze the biological sample using an analytical device associated with the medical toilet. The tag may be identified and quantified to then identify and quantify the nutritional or drug composition the subject consumed along with the tag. This system may be used to track the source of a food or drug, confirm compliance to a prescribed diet or drug treatment, confirm drug consumption in clinical trials, identify the source of contaminated food, and identify the food substances used to produce food products.

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: We disclose a method of using taggants to assess how and to what extent a drug in a drug composition that a user has consumed has decayed in response to storage conditions and time. The taggants may decay in response to environmental conditions which cause different drugs to lose their efficacy. These environmental conditions may include light, temperature, oxidation, and age. The taggants may be detected in biological samples, including urine and feces. By identifying the taggants, the drug composition and other information relating to the drug may be identified. Additionally, quantification of the different taggants may be used to determine whether the drug in the drug composition has been exposed to environmental conditions which may reduce its efficacy.

Abstract: A synthetic aperture photoplethysmography (PPG) sensor is disclosed. A group or matrix of contiguous PPG sensors located on a toilet seat are conditionally combined based on sensor measurements. Conditional combinations may be based on timing data and signal-to-noise ratio data of each of the PPG measurements. Measurements associated with the conditional combinations are then used to determine a cardiac function of a toilet user.

Abstract: Data is remotely collected from a plurality of fasteners in response to a query signal wirelessly transmitted by a reader. Each of the fasteners includes a sensor for measuring a parameter related to the stress on the fastener. A device adapted to be attached to each of the fasteners receives the query signal, activates the sensor to measure the parameter and wirelessly transmits the data including the parameter to the reader.

Abstract: We disclose a tag for tracking and identifying pharmaceutical and nutritional products. The tag includes a paramagnetic microparticle which is connected to at least one unique and detectable chemical. The chemical may be coated on the paramagnetic microparticle or connected through functional groups. The tags may be too large to be taken into the bloodstream and therefore remain in the user's gastrointestinal tract. The tags may be fully or partially isolated from feces for analysis. The tags are attracted to an external electromagnetic force but are not magnetically attracted to each other. Consequently, the tags are safe to ingest. The tags may vary in volume or mass so as to be separable according to mass. The tags may be non-spherical in shape thus increasing the surface area to volume ratio and increasing the amount of chemical which may be attached as a taggant.
