A61B 10/00
E03D 11/02
G01J 3/02

Abstract:

We disclose a device and method for collecting a urine sample as a user urinates into a toilet. The device further conducts analytical measurements which may include spectral, colorimetric, and chemical assays. The user need only urinate normally into the toilet. A urine collection trap, which includes a vertical slit, may capture a urine sample which has a volume in the microliter range. Pumps may divert the urine from the vertical slit into a conduit that is connected to spectral analysis devices and other devices for analyzing the urine sample. The disclosed device is both convenient and prevents unsanitary urine spills.

Abstract:

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.

G01J 3/51

Abstract:

A spectrometer having a plasmonic filter/microlens arrangement is provided. The spectrometer can include a controller; an image sensor with a pixel array formed by a plurality of pixels coupled to the controller; and an optical layer over the image sensor. The optical layer can include a plasmonic microlens array having a plurality of microlenses positioned over the spacer layer, each microlens of the plasmonic microlens array focusing light on one of the plurality of pixels, and a plasmonic filter array arranged with the plasmonic microlens array such that light incident on each of the plurality of pixels has a transmission function. The microlenses and plasmonic filters can be formed of a composite structure.

International Classification:

G01N 27/62

Abstract:

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.

International Classification:

C12N 15/10

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.
