    摘要： 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.

    摘要： 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.

    摘要： 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.

    摘要： We disclose a telemedicine device for tracking, dispensing, and retrieving medical supplies as well as methods of its use. The device includes a medical supply dispensing and retrieving station which includes a medical supply dispenser and medical supply receptacle. Both the medical supply dispenser and medical supply receptacle may include multiple compartments which house medical supplies. The device may include a communication port for receiving prescription information. The device includes a personal identification indicator which verifies the identity of the user and links the identity to the user's prescription information. The device may include medical devices. The medical devices may conduct measurements to confirm efficacy of a medical supply or screen for side effects. The device may confirm proper usage of a medical supply by weighing an unused portion of the medical supply and comparing it to the weight expected for the amount that should be remaining.
