A system and method of tracking activity includes a motion sensor, a light source and a light detector. The light detector is configured to capture an amount of the light that is reflected back to the light detector, at least a first portion of the light reflected back to the light detector is reflected from a blood vessel disposed under a skin adjacent to the housing. A processor is in communication with the motion sensor and the light detector and can process the reflected light to identify heart beats and produce an indication of a heart rate. The indication of the heart rate can be displayed on the display screen as an option, in addition to the metrics that quantify the motion data.

Virtual Dermatopathology Regional Hub (VDRH) receives one or more of the Detailed Virtual Tissue Models generated at one or more of the Virtual Dermatology Workstations and selectively communicates each to at least one pathology site. Each pathology site includes one or more Dermatopathology Information Processing Workstations (DIPWs). Thereafter, the VPM receives from the one or more of the pathology sites a plurality of pathology reports generated using said DIPWs and respectively corresponding to the plurality of DVTMs. The VPM then selectively communicates the pathology reports to the imaging facility which generated respectively the DVTM upon which each said pathology report is based.

An organ image capture device is provided with an imaging unit, a display unit, and an information extracting unit. The imaging unit images an organ of a living body and acquires an image thereof. The display unit displays, together with the image acquired by imaging by the imaging unit, an indicator for specifying an organ imaging position satisfying an imaging condition including a condition relating to illumination at the time of imaging by the imaging unit. The information extracting unit extracts information necessary for diagnosing the degree of health of the living body from an image which is acquired by imaging by the imaging unit and is within a range specified by the indicator.

A sensor unit, a biological information detection device, an electronic apparatus, a biological information detection method, and the like, capable of acquiring highly accurate pulse wave information on the basis of a plurality of signals having different characteristics. The sensor unit includes a first light emitting portion that emits light toward a subject, a second light emitting portion that emits light toward the subject, and a light receiving portion that receives light from the subject, in which, in a case where a height of a contact position or a contact region with the subject in a position or a region corresponding to the first light emitting portion is indicated by H1, and a height of a contact position or a contact region with the subject in a position or a region corresponding to the second light emitting portion is indicated by H2, a relationship of H1>H2 is satisfied.

Exemplary embodiments of the present disclosure include apparatus and methods to identify endometrial tissue.

The invention relates to methods and devices to identify an infection via light scatter from a tissue surface.

A chewing detecting device includes: earphone-type external auditory meatus sensors which have a pair of a light emitting element and a light receiving element and in which the light receiving element receives reflective light of light emitted by the light emitting element into an external auditory meatus to output a voltage signal corresponding to a light receiving amount; association processing means associating an output signal of the external auditory meatus sensors with a motion of a jaw, and outputting a chewing signal showing that the jaw performs chewing; and chewing section sensing means which determines whether or not an output of the external auditory meatus sensors is based on the motion of the jaw (within a chewing section), and which invalidates the output of the association processing means when the output of the external auditory meatus sensors is not based on the motion of the jaw (without the chewing section).

Systems, devices and methods for noninvasive analysis of tissue, by irradiating a surface of the tissue with infrared radiation such that an interaction of the radiation with a component of the tissue other than water in two spectral bands is substantially identical, measuring an intensity of the radiation that emerges from the tissue in each of the spectral bands, determining change in at least one of shape and intensity of signals received by the at least one radiation detector, calculating a relative absorption by the tissue of radiation in one of the first and second spectral bands relative to absorption by the tissue of radiation in the other of the first and second spectral bands, and determining concentration of a predetermined substance, in accordance with the calculated relative absorption and in accordance with determined change in the received signal.

Methods for preventing or treating motor-related neurological conditions include using ocular light therapy in connection with a conventional therapy for a motor-related neurological condition, such as a drug regimen, to adjust levels of melatonin and/or dopamine in the body of a subject. The ocular light therapy may include elevated levels of blue-green light or green light (e.g., light within a wavelength range of 460 nm to 570 nm, 490 nm to 570 nm, about 520 nm to 570 nm, etc.). The ocular light therapy may also include reduced levels of amber, orange and/or red light. Methods for diagnosing motor-related neurological conditions include use of ocular light therapy to cause a subject to temporarily exhibit one or more symptoms of any motor-related neurological condition to which the subject is predisposed, or which the subject may already be experiencing. A temporary increase in such symptoms may be effected by ocular administration of light including increased amounts of amber, orange and/or red light.

An apparatus and method for creating a three dimensional imaging system is disclosed. There is a first source of laser light and a second source of laser light having a wavelength different from the wavelength of the laser light of the first source. The laser light from the first and second sources are combined, and the combined laser light is transmitted to a scanner. The scanner further transmits the combined light to a surface to be imaged.
