Publication number: 20140114199Abstract: A magnetic-flap optical sensor has an emitter activated so as to transmit light into a fingertip inserted between an emitter pad and a detector pad. The sensor has a detector responsive to the transmitted light after attenuation by pulsatile blood flow within fingertip so as to generate a detector signal. Flaps extend from the emitter pad and along the sides of a detector shell housing the detector pad. Flap magnets are disposed on the flap ends and shell magnets are disposed on the detector shell sides. A spring urges the emitter shell and detector shell together, so as to squeeze the fingertip between its fingernail and its finger pad. The flap magnets have opposite north and south orientations from the shell magnets, urging the flaps to the detector shell sides and squeezing the fingertip sides. These spring and magnet squeezing forces occlude the fingertip blood flow and accentuate a detector signal responsive to an active pulsing of the fingertip.Type: ApplicationFiled: October 17, 2013Publication date: April 24, 2014Applicant: Cercacor Laboratories, Inc.Inventors: Marcelo M.
