A method, apparatus and system that illuminates one face of a lateral flow assay test strip or test strip assembly with light of selected wavelengths and intensities and measures the resulting light intensities at the opposite face at the test stain line region and adjacent regions, in order to determine the value of analyte concentration over an extremely wide range, including values too small to produce a visible test stain line.

Methods to register and interpret lateral flow test strip assay measurements by transmission of multi-wavelength visible and near-visible light

A system, apparatus, and method using multiple complementary sensors for the monitoring and wireless communication of several respiration characteristics—that is badge-size, wearable on the outside of clothing, and non-invasive.

Multiple sensor wearable and portable non-invasive respiration monitoring instrumentation

A system, apparatus, and method for registering and interpreting the results of lateral flow assay determination by using electric, magnetic, and RF sensors incorporated within the test strip, attached to the inside of the enclosure for same and/or contained in a test fixture; instead of relying on optical inspection techniques. This method features high reliability, low cost, and ability for quantitative and dynamic measurements.

Electric, magnetic, and RF sensor based methods to register and interpret lateral flow assay measurements

A system, apparatus, and method using multiple complementary sensors for the monitoring and wireless communication of several respiration characteristics&#x2014;that is badge-size, wearable on the outside of clothing, and non-invasive.

A system, apparatus, and method for detecting the presence and amount of liquid and/or solid excrement in diapers or other undergarments, using a miniature ultra-low power near-field electromagnetic probe, applicable circuitry, and additional sensor types, that is hand-held or attached to the outside of said garments

Contactless magnetic probe sensing and impedance imaging of liquid and solid excrement in diapers and other underclothing

An ultra-miniature and micro-powered system, apparatus, and method utilizing electromagnetic imaging via minute eddy currents, analog circuit averaging and artifact cancellation, that attaches to the outside of clothing and measures internal bodily functions including but not limited to heart rate, respiration rate, and wetness of underclothing.

Micro powered ultra-high resolution electromagnetic sensor with real time analog circuitry based artifact cancellation

Eddy current measurement systems for a variety of bio-metric and other applications, where the target composition and/or other aspects cause relatively small eddy current losses, thus requiring a very high Q tuned circuit probe, and where ultra-miniature and ultra-low power products are required for convenient, non-invasive, and intrinsically safe wearable use.

Contactless or non-invasive physical properties measurement instrument using eddy current-reduced high Q resonant circuit probe

A system permits non-invasive measurement and wireless reporting of bodily functions of a subject wearing a diaper and an outer layer of clothing outside the diaper. The system comprises a butterfly housing which houses a plurality of sensors, a processor, a memory, and wireless circuitry. The butterfly housing has two double-arc shaped projections. Each double-arc shaped projection extends from an opposing side of the housing at a perimeter of the butterfly housing and has associated therewith a coupling clip. Each double-arc shaped projection and the associated coupling clip is configured to sandwich the outer layer of clothing to removably couple the butterfly housing to the outer layer of clothing without necessitating any modification to the outer layer of clothing. Every measurement of the bodily functions occurs without any direct contact between a skin of the subject and the butterflying housing.
