20130190630 | OPTICAL VITAL SIGN DETECTION METHOD AND MEASUREMENT DEVICE - A vital sign measurement device includes an optical sensing system and an output unit. The optical sensing system includes an optical source, an optical refractor, and an optical detector. The optical sensing system is placed against the anatomical location of the subject to sense movement corresponding to an arterial pulse. The optical sensing system can sense an arterial pulse from the movement, bending, or compression of at least one portion of the optical sensing system relative to other portions of the optical sensing system resulting in a change in an optical signal received by the optical detector. The output unit generates a measure of a vital sign. | 07-25-2013 |
20120130260 | OPTICAL POWER MODULATION VITAL SIGN DETECTION METHOD AND MEASUREMENT DEVICE - A vital sign measurement device includes a sensor fixation device, a sensor frame, an optical sensing system, and an output unit. The sensor fixation device is adapted to be placed against an anatomical location of a subject. The optical sensing system includes an optical waveguide, an optical source device to supply optical energy to the optical waveguide, and an optical detector to detect an amount of optical energy exiting the optical waveguide. The optical sensing system is adapted to sense an arterial pulse from the compression or flexing of at least a portion of the optical waveguide resulting in reduction of the amount of light exiting the optical waveguide. The output unit is configured to receive a signal indicative of the amount of light exiting the optical waveguide and to generate a measure of the vital sign based at least in part on the received signal. | 05-24-2012 |

20090073461 | Waveguide and Optical Motion Sensor Using Optical Power Modulation - An optical motion sensing device included a sensor frame defining an opening, a sensor pad disposed in the opening, an optical sensing system adapted to detect an amount of movement of the sensor pad in the sensor frame, and an output unit. The optical sensing system includes an optical waveguide, an optical source device, and an optical detector. The optical waveguide is positioned within the sensor frame such that the movement of the sensor pad results in the flexing or compressing of the optical waveguide. The optical source device supplies optical energy to the optical waveguide. The optical detector detects an amount of optical energy exiting the optical waveguide. The output unit is configured to receive a signal indicative of the amount of optical energy exiting the optical waveguide and to generate a measure of the amount of movement of the sensor pad from the received signal. | 03-19-2009 |
