摘要： 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.

摘要： 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.

摘要： A toilet comprising a rinsing seat, a rimless bowl, and a helical loop trapway is disclosed. An annular cavity for the purpose of storing and dispensing rinse water from the rinsing seat is disclosed. Outlet nozzles arranged about the circumference of the rinsing seat and designed to dispense rinse water at the rimless bowl are disclosed. Rinsing seat supports, hinge assemblies, and seat sensors which offer additional functionality to the rinsing seat are also disclosed. The toilet includes a steep interior surface with a titanium dioxide coating and actuatable ultraviolet light sources. The titanium dioxide has antimicrobial properties in the presence of ultraviolet light to sanitize the toilet. The ultraviolet light source is actuatable to control when the antimicrobial properties of the titanium dioxide coating are activated. The exterior of the toilet is coated with doped titanium dioxide which is antimicrobial in the presence of visible light.

摘要： 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.

摘要： We disclose a toilet system which analyzes solid waste to detect tags which were associated with pharmaceutical or nutritional products and excreted in the solid waste of a user. The toilet system may include a receptacle for receiving solid waste, a liquid dispenser for providing a liquid to assist in dispersing the solid waste, a solid waste dispersing system which may mix the solid waste with the liquid thereby homogenizing the solid waste, and an electromagnetic signature detector which may analyze the tags in the solid waste. The electromagnetic signature detector may include a selective binding surface which may bind tags present in the solid waste and which may be connected to a transducer which senses the presence of bound tags.

摘要： 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.

摘要： The navigation system includes a series of bar codes and a bar code reader. The bar codes are placed at positions throughout the area to be navigated. The bar code readers scan the bar codes as a user moves through the area to be navigated. The navigation system may include a processor which includes instructions for receiving the user's current position and at least one location the user wishes to reach. The processor assembles the most efficient route from the user's position to the locations the user wishes to reach. The navigation system may include an augmented reality viewing device which receives signals from the processor and displays an augmented reality view to the user. The augmented reality view includes augmented reality images which provide step-by-step instructions from the user's position to the locations the user wishes to reach.

摘要： 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.

摘要： 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.

摘要： The drug tracking system may be used to screen a subject's bodily waste and to identify a drug the subject has consumed. The system includes drug tags which include a one or more food dyes, each detectable in a subject's bodily waste using photographic or absorption spectroscopic analysis. The system may further include a database in which is stored the spectral signature of each drug tag and the unique drug associated with each drug tag. A spectral analysis obtained by analyzing a bodily waste sample may be entered into the database. The database may include instructions for comparing the spectral analysis to the spectral signature of each drug tag. The instructions may further report the unique drug associated with a drug tag which has a spectral signature matching the spectral analysis.
