    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.

    Abstract: A method and apparatus correcting errors associated with timing offsets in radiofrequency coils. The method and apparatus include a memory element and a controller. The controller is configured to execute a set of instructions to receive data of a plurality of signals, the plurality of signals comprising at least one projection echo. The controller is also configured to identify a plurality of offsets of the plurality of signals based on the at least one projection echo. The controller is also configured to apply the plurality of offsets to a k-space of the plurality of signals.

    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.
