Patent number: 9808204Abstract: 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.Type: GrantFiled: August 3, 2012Date of Patent: November 7, 2017Assignee: Valencell, Inc.Inventors: Steven Francis LeBoeuf, Jesse Berkley Tucker, Michael Edward Aumer
