Abstract: The present invention is directed to a toilet that includes a slanted fill tube with an optical proximity sensor positioned on or within the inner surface of the fill tube. The optical proximity sensor includes an incoherent light source and a photodiode. The optical proximity sensor as disclosed herein detects small changes in volumes added to a toilet bowl. Consequently, small volumes of excrement that are deposited in the toilet bowl by a user may be detected with greater accuracy. In some embodiments, information about the volume of urine or feces deposited into the toilet bowl is recorded and calculated by a processor. Other sensors, including a toilet bowl water level sensor and a gas sensor may collect data in combination with the optical proximity sensor to provide more complete information about the user's health.

Abstract: We disclose a microfabricated device for both extracting and preconcentrating samples for gas chromatography analysis. The device includes a conduit with at least two sections and multiple ports which may be connected to multiple gas chromatography columns. The inner surface of the conduit may be coated with multiple sorbents which bind volatile analytes with different affinities. The sections of the conduit may be divided by a thermal barrier which inhibits heat transfer between sections. Consequently, each section may be independently heated to encourage desorption of volatile analytes. The disclosed device separates and concentrates volatile analytes into different pools according to their chemical and physical properties before they enter a gas chromatography column that is optimized for that pool. The device reduces the amount of heat and time needed to perform gas chromatography analysis as well as avoids the need for purified gas sources typically used for the moving phase.

Abstract: We disclose a medical toilet that includes at least one stethoscope probe in the toilet lid. The stethoscope probes may be mounted on a compliant extension which extends the stethoscope probes toward a user seated on the toilet. The medical toilet may include a device which adjusts the height of the stethoscope probes to adjust for different size users and to collect measurements from different parts of a user. The medical toilet may include a device which records the sounds collected by the stethoscope and may also include a controller that proposes a diagnosis based on the sounds collected by the stethoscope. The medical toilet may also transmit recordings and other information to an external machine.

Abstract: We disclose a method of tagging a variety of pharmaceutical or nutritional products in which well-studied chemicals may be added to the products in unique ratios. The identities of the chemicals and their relative ratios comprise unique taggants. The taggants may identify which of multiple distinct categories the product falls within. The method includes the step of systematically varying the relative concentrations of the chemicals resulting in multiple ratios of the chemicals. The plurality of ratios of a defined set of chemicals may be collected to form a library of taggants associated with specified items or categories. As the number of chemicals added per product increases, the library supports more categories and the system is less likely to produce a false positive. The method may result in a series of taggants for each item which is single fault tolerant or double fault tolerant.

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, 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.

Abstract: We disclose a device that both extracts and preconcentrates volatile analytes in preparation for separation by gas chromatography. The device includes a conduit that may include two, and sometimes three, separate sections that are connected end-to-end, but which may be separated prior to inserting into a gas chromatograph port. The inner surface of each section is coated with one or more sorbents, each with a different affinity for volatile analytes. The sorbents may be positioned along the sections of the column in order of relative affinity for volatile analytes. The sections may be heated independently of each other to release the volatile analytes from the sorbents more quickly. This device reduces the time and the temperature required to achieve separation by gas chromatography. The device may be used to perform gas chromatography in ubiquitous environments such as the home or a mobile situation.

Abstract: We disclose a system which may be used to analyze data collected from a customized test strip. The customized test strip may include a set of reaction pads which are selected to address the medical needs of a specific user. The system may include a data analysis platform which analyzes the data and proposes a second customized test strip. The second test strip may comprise of a set of reaction pads that the data analysis platform selects for the user based on the analysis of the first customized test strip. The data analysis platform may propose that additional diagnostic metrics be collected from the user to assist in diagnosis. The customized test strips and the additional diagnostic metrics may be within a medical toilet.

Abstract: Body temperature of a toilet user may be non-intrusively obtained on a regular basis using one or more non-contact optical temperature sensors having a field-of-view between a surface of a toilet bowl and a user of the toilet while the user is releasing body excrement into the toilet. An output of the non-contact optical temperature sensor is used to determine a body temperature of the user based on at least one of: a temperature of the body excrement while the body excrement is in the field-of-view of the non-contact optical temperature sensor, a temperature of a perineal area of the user while using the toilet, a temperature of the body excrement while the body excrement is detached from the body and falling toward the surface of the toilet bowl, or a combination thereof.
