Michael Edward Aumer - Raleigh NC, US

Assignee:

Valencell, Inc. - Raleigh NC

International Classification:

A61B 5/00

US Classification:

600309

Abstract:

Methods and apparatus for qualifying and quantifying excitation-dependent physiological information extracted from wearable sensors in the midst of interference from unwanted sources are provided. An organism is interrogated with at least one excitation energy, energy response signals from two or more distinct physiological regions are sensed, and these signals are processed to generate an extracted signal. The extracted signal is compared with a physiological model to qualify and/or quantify a physiological property. Additionally, important physiological information can be qualified and quantified by comparing the excitation wavelength-dependent response, measured via wearable sensors, with a physiological model.

International Classification:

A61B 5/00

US Classification:

600310, 600323

Abstract:

Multi-wavelength optical apparatus includes an optical emitter, and an energy transition layer positioned adjacent to the optical emitter. The energy transition layer generates multi-wavelength electromagnetic radiation when monochromatic light from the optical emitter passes therethrough. The energy transition layer includes a plurality of luminescent films, and each film is configured to luminesce at a respective different wavelength range when monochromatic light from the optical emitter passes therethrough. The plurality of luminescent films may be arranged in contacting face-to-face relationship or may be arranged in an array. The luminescent films may include rare-earth doped oxides, phosphors, metal-doped oxides, rare-earth doped nitrides, nanostructures, and/or nanostructured films, etc. The optical emitter may be a light emitting diode (LED), a laser diode (LD), an organic light-emitting diode (OLED), a resonant cavity light emitting diode (RCLED), and/or an edge-emitting diode (EELED).
