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.

An apparatus and method to assist making treatment decisions for burn injuries. The apparatus will leverage computational imaging methodologies with conventional thermographic analysis techniques. Using infrared sensors, computational image analysis, and burn assessment using thermographic imaging, a complete burn assessment imaging device can be fabricated entirely from commercially-available components. This device will use advanced software paired with a smartphone-mounted infrared camera to perform a detailed thermographic analysis using a burn triage algorithm.

New activity recognition, recording, analysis and control techniques, systems and sensors are provided. In one embodiment, multiple sensory tags with unique identification and data transfer attributes, create positional, movement, orientation and acceleration data and supply it to a control system. The tags may be placed at location(s) on the user's body, clothing, personal effects, exercise equipment and other activity-relevant locations, to enhance activity recognition and mapping. The system may define a personal activity space, sample data preferentially from that space, and perform a simplified form of object-recognition to determine, record and analyze user activities.

Brain function measurement device including: first light-irradiation probe to irradiate a brain of a subject with light; first light-detection probe to detect light reflected by the brain among the light from the first light-irradiation probe; second light-irradiation probe to irradiate the brain with light; second light-detection probe to detect light reflected by the brain among the light from the second light-irradiation probe; and control unit configured to adjust a light amount irradiated by the second light-irradiation probe so that the light amount measured with respect to a channel between the first light-detection and the second light-irradiation probes becomes an observation value with respect to a channel between the first light-irradiation and the first light-detection probes, and to adjust a light amount detected by the second light-detection probe so that the light amount measured with respect to a channel between the second light-irradiation and the second light-detection probes becomes the observation value.

Compositions and methods for assessing blood vessels and organs of the body are disclosed herein, specifically methods for assessing the vasculature of the eye.

An ear-worn device includes a speaker, an optical emitter, an optical detector, a processor, and a housing configured to be positioned within an ear of a subject, wherein the housing encloses the speaker, optical emitter, optical detector, and processor. The housing includes at least one window that exposes the optical emitter and optical detector to the ear of the subject, and the housing includes at least one aperture through which sound from the speaker can pass. Light transmissive material is located between the optical emitter and the at least one window and is configured to deliver light emitted from the optical emitter to an ear region of the subject at one or more predetermined locations. Light transmissive material is positioned between the optical detector and the at least one window and is configured to collect light external to the housing and deliver the collected light to the optical detector.

The present invention relates to a system, method and corresponding computer program for milk ejection reflex (MER) determination, the system comprising a breast shield arrangement (1) for a breast pump (2) configured to be attached on a first breast of a female, a physiological sensor unit (4) for receiving a physiological reception signal from the second breast, which is opposite to the first breast, wherein the physiological reception signal is indicative of fluid contents in the second breast, and wherein the system is configured to determine a milk ejection reflex based on a change in fluid contents in the second breast. It finds particular application during and in connection with breastfeeding and allows for direct detection of the beginning of the milk flow in the breast, i.e. the occurrence of the MER, without delay and with a high degree of precision.
