Abstract: A device for measuring and monitoring heart rate, respiration rate, and oxygen saturation of a subject is disclosed, which includes a biometric sensor board having a photosensor adapted to measure reflectance of red and infrared lights off skin tissue, wherein the biometric sensor board adapted to control one or more light emitting diodes (LEDs), wherein brightness of the LEDs are automatically adjusted to account for skin tone, thereby generating photoplethysmographic data, a processor unit adapted to analyze data measured by the biometric sensor board, and a display adapted to display results of the processed data remotely.

Abstract: This invention generally relates to methods useful for measuring heart rate, respiration conditions, and oxygen saturation and a wearable device that incorporate those methods with a computerized system supporting data collection, analysis, readout and sharing. Particularly this present invention relates to a wearable device, such as a wristwatch or ring, for real time measuring heart rate, respiration conditions, and oxygen saturation.

Abstract: This invention relates to a method for measuring viscosity of a fluid using particle diffusometry (PD). The method finds practical applications in detecting structural and functional changes of a biomolecular composition by comparing the viscosity change as compared with the standard of the biomolecular composition. This method may also find uses in clinical diagnosis and quality control of clinical biological medicines, food and feeds during the process of manufacturing, distribution and consumption.

Abstract: This invention relates to an improved version of paper-based analytical device and method for chromatographic chemical or immunoassays. Particularly, this present invention discloses a device and a method for reducing smears and improving sharpness and intensity of test sample readout for a multi-step chemical assay or immunoassay by introducing two additional elements, a time-delay pad (2) and a mixer (1), to the conventional two-dimensional paper network device (2DPN).

Abstract: A system for solar disinfection of fluid. One most preferred version of the system includes: (a) A UVTC, made of a polyethylene laminate film with an approximately rectangular plan, providing: a. A first compartment. b. A second compartment for holding fluid, with a port to fill and dispense. (b) A Disinfection Monitor Module (“DMM”) located in the first compartment which: a. Includes at least one sensor to measure radiation intensity. b. Provides at least one user interface: c. Contains a wireless communication interface. d. Operates according to a process that ensures sufficient cumulative exposure of the contained fluid to solar UV to achieve adequate solar disinfection. Alternative embodiments may also include sensors to detect additional characteristics, such as transmittance, turbidity, “combined transmittance,” and/or temperature.
