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.

The sensor platform array includes a plurality of sensors and one or more sensor platforms. Each sensor may be mounted on a sensor platform. 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.

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.

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.

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.

Method of determining consumption of decayed drug through drug taggants

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.

We disclose a drug tracking system and method of use which may be used to screen a subject's bodily waste in order to assess whether the subject has consumed a drug. The system includes a drug composition which is tagged with at least one artificial sweetener that may be detected in the subject's bodily waste. The subject may consume the tagged drug and a user may obtain a sample of the subject's bodily waste. The bodily waste sample may be analyzed to detect the artificial sweetener or its metabolite. In some embodiments, the result of the analysis of bodily waste may be entered into a database, compared to standards that comprises analyses of a plurality of drug tags, and the identity of the drug tag, and consequently the drug composition, determined.

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, moisture, 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.

The present disclosure describes a toilet apparatus for detecting a drug marker in a urine sample. The drug markers are fluorophores each of which emits a unique fluorescence spectrum. Accordingly, the toilet does not detect the drug but rather, the drug marker. The user consumes a drug composition which includes a drug and a fluorescent drug marker. The user urinates normally into the toilet and fluorescence spectrometer within the toilet analyzes the urine for drug markers based on their unique fluorescent spectra. Computer software associated with the toilet identifies, and in some embodiments, quantifies the fluorescent spectra by comparing the detected spectra to known spectra of fluorescent markers associated with the drug.

We disclose a method of tagging pharmaceutical and nutritional products with nanoparticles which include noble metals. The disclosure describes a plurality of nanoparticles each with either a different size and/or shape. The nanoparticles of different sizes and shapes are distinguishable using spectroscopic techniques because each is associated with different optical properties and have a different spectral signature. The different optical properties are at least due to the unique size or shape of the nanoparticles. Each of the plurality of nanoparticles may be associated with a different characteristic of the tagged pharmaceutical or nutritional product. The method includes mixing the nanoparticles with or adhering the nanoparticles to the tagged pharmaceutical or nutritional product. Two or more of the plurality of nanoparticles may be mixed with or adhered to the tagged pharmaceutical or nutritional product in a ratio and the ratio may be associated with a characteristic of the product.
