  • Patent number: 9924880
    Abstract: A method implemented by a device to measure a bodily parameter includes transmitting, by a transmit (Tx) antenna of an antenna pair, a first radar pulse to a receive (Rx) antenna of the antenna pair. The method also includes receiving, by the receive (Rx) antenna, the first radar pulse. The first radar pulse travels through a radar target between the Tx antenna and the Rx antenna. The method further includes transmitting, by the Tx antenna, a second radar pulse to the Rx antenna. In addition the method includes receiving, by the Rx antenna, the second radar pulse, wherein the second radar pulse travels through the radar target between the Tx antenna and the Rx antenna. The method also includes determining a bodily parameter within the radar target as a function of the transmission and the reception of the first radar pulse and the second radar pulse.

  • Publication number: 20170071516
    Abstract: A method implemented using a device to measure hemodynamic parameters is provided. The method includes transmitting, by the client device, a message to the server. The method includes capturing, by a camera, a first image of a plurality of images of a target region while two light emitting diode (LED) sensors emit light, via a collimated lens, on the target region. The method also includes capturing, by the camera, a second image of the plurality of images of the target region while the two LED sensors emit light, via the collimated lens, on the target region. The second image is captured a predetermined time after the first image is captured. The method further includes determining one or more hemodynamic parameters based on a difference between the first captured image and the second captured image.

  • Publication number: 20140207398
    Abstract: Various apparatuses and methods are provided for monitoring individual appliance energy consumption using non-intrusive load monitoring (NILM). For example, one method includes detecting an ON event and an OFF event within a segment of streaming power input and extracting the streaming power input associated with the ON event in response to detecting the ON event. The extracted streaming power input includes a waveform associated with the ON event recorded over a time frame. The method also includes normalizing the waveform to reveal one or more unique variations and classifying the normalized waveform based on the one or more unique variations. The method further includes matching the ON event with a correlating OFF event based at least on the classification of the normalized waveform and calculating power consumed from a time of the ON event to a time of the OFF event.
