摘要： An apparatus for pivotally fixing a non-driven wheel assembly to a vehicle frame is disclosed. The apparatus provides a trough through which non-driven wheel assembly components can be passed and protected. In one embodiment, the trough is circular in shape and is fully enclosed by the apparatus. In other embodiments, the trough has various shapes and comprises retaining members to secure and protect non-driven wheel assembly components. A suspension system interface is provided that allows the apparatus to suspend the non-driven wheel assembly. Openings used to pivotally and rigidly fix a mounting plate, suspension system, pivotal axes, and fender assemblies are also disclosed and claimed herein.

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 health-monitoring system includes one or more cameras which collect graphic data and a controller which calculates body proportion measurements based on the graphic data. Specifically, the health-monitoring system measures a user's body parts and their relative positions. These measurements may be combined with those collected by other devices and sensors within the system which conduct other health-related measurements. The other devices and sensors may be housed within a container and a least one of the cameras may also be housed within the container. In some embodiments, the container is a fixture, such as a bathroom medicine cabinet . The camera may be invisible to a user as positioned within the fixture. Consequently, the user may move and behave normally without changes which may occur due to being self-conscious of the camera. Calculations may occur within the controller or on a remote server to which data is transmitted.

摘要： 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.

摘要： A toilet seat apparatus is disclosed herein which, in some embodiments, includes a cavity, an acoustic transducer, orifices, and an impedance matching substance dispenser. The dispenser may include a reservoir, a conduit, and a pump. The reservoir dispenses an impedance matching substance may be connected to the conduit and pump. The toilet seat apparatus performs ultrasound analyses of a user seated on the toilet. The impedance matching substance may be what is known as ultrasound gel which improves conduction during the acoustic transduction of an ultrasound analysis. This apparatus permits a user to receive an ultrasound analysis of the thigh, including automatically dispensing the ultrasound gel, while seated on a toilet seat.

摘要： The tandem differential mobility spectrometer (DMS)-ion modulator instrument provides improved resolution relative to traditional DMS for molecules with larger masses. The instrument includes multiple ion-bunching electrodes, each with an AC field synchronized to the transit time of the ion flow which is positioned downstream of a DMS. The ion bunching electrodes produce each a mobility-dependent modulation of the ion current. The ratio of AC to DC current provides a measure of the mobility of a large ion, even if it has little differential mobility, thereby extending the useful range of mobility characterization of a DMS system. The instrument does not require high voltages or high frequencies. Modulation before DMS separation or between tandem DMS separations produces a variable range of analyte and reactant ion densities as well as spatially separating negative and positive ions to reduce ion recombination.

The ion bunching electrode produces a mobility-dependent modulation of the ion current. The ratio of AC to DC current provides a measure of the mobility of a large ion, even if it has little differential mobility, thereby extending the useful range of mobility characterization of a DMS system. The instrument is more compact than a larger traditional ion mobility spectrometer and does not require high voltages or high frequencies. Modulation before DMS separation or between tandem DMS separations produces a variable range of analyte and reactant ion densities as well as spatially separating negative and positive ions to reduce ion recombination.
