  • Motion cancellation of optical input signals for physiological pulse measurement
    Patent number: 8858454
    Abstract: A pulse rate sensor that includes an accelerometer for measuring periodic motion and a piezo sensor for detecting erratic motion is capable of more accurately determining pulse rate by accounting for these types of motion. The pulse rate sensor in accordance with the present invention diminishes pulse rate signal degradation due to erratic motion through a combination of algorithms that control signal boosting, waveform refinement and signal noise suppression.
    Type: Grant
    Filed: July 13, 2011
    Date of Patent: October 14, 2014
    Assignee: Basis Science, Inc.
    Inventors: Richard A. Nazarian, Lori E. Lucke, Susan S. Alfini, Mark J. Bina, Don W. E. Evans, Paul Harris, Michael W. Geatz

  • Nasal vibration transducer
    Patent number: 6894427
    Abstract: A vibration transducer specially configured for attachment to a subject's nose for producing an electrical output signal relating to a subject's snoring pattern. The transducer is shaped so as to have a rectangular portion for bridging the dorsum at least one polygonal pad area adapted to be adhesively secured to the ala nasi. The transducer is a laminated arrangement incorporating a polyvinylidene fluoride film exhibiting piezoelectric properties.
