At least one of the plurality of biosensors is disposed at the auxiliary supporter.

An electronic device of a charging module system may include a housing having a first surface facing a first direction and a second surface facing a second direction opposite to the first direction; a display device at least partially is exposed through the first surface to display information to the outside; a biometric sensor disposed to be exposed in at least an area of the second surface and sensing biometric information of a user; a battery disposed between the display device and the biometric sensor; and a plurality of electrodes disposed adjacent to the at least an area of the second surface and formed to be exposed in at least another area of the second surface, in which the plurality of electrodes may surround at least a portion of the biometric sensor, and each of the plurality of electrodes has a notch protruding or recessed at least at one end.

This disclosure relates generally to speckle image analysis, and, more particularly, to a system and method for imaging of localized and heterogenous dynamics using laser speckle. Existing speckle analysis techniques do not offer the capability to achieve both the dynamic phenomenon which carries over a specific time duration and localizing the extent of the activity at a single, chosen instant of time simultaneously. The present disclosure records an image stack consisting of N speckle images sequentially over a period, divides the image stack into a spatial window and a temporal window, converts the speckle intensity data comprised in the spatial window into a column vector. Construct a diagonal matrix and extract a singular value from the diagonal matrix, then defines a speckle intensity correlation metric using the plurality of singular values, defines a speckle activity and generates a speckle contrast image by graphically plotting the speckle activity values.

A photoplethysmography (PPG) device includes an equipment module which includes a photodetector and first and second light emitting diodes (LED's) adapted to emit light of first and second wavelengths, respectively. The PPG device also includes a mask covering the patient facing extremity of the equipment module so that when the device is applied to a patient the mask is situated between the patient and the patient facing extremity. A processor is adapted to control drive current and/or operating time of the second LED to achieve an elevated localized body tissue temperature of a patient to which the PPG device is applied.

A dialysis access site monitoring system may generate a treatment recommendation for treating a condition of an access site based on a video of the access site. The dialysis access site monitoring system may include an apparatus having a processor and a memory coupled to the processor. The memory may include instructions that, when executed by the processor, may cause the processor to generate video information based on a video of a dialysis access site of a patient, determine change in the number of pixels (CNP) information of the video information, the CNP information associated with movement of a skin surface of the patient due to blood flow through the dialysis access site, determine frequency domain information of the CNP information, determine a maximum-to-median power (M2) value of the frequency domain information, and determine at least one access site characteristic based on the M2 value.
