An electronic device is disclosed that includes: communication circuitry, a memory operatively coupled to a processor and storing instructions which, when executed, cause the processor to: receive first physiological data and second physiological data obtained by measuring a physiological state of a user's body, obtain measurement environment data for an environment where each of the first physiological data and the second physiological data is measured, determine validity of each of the first physiological data and the second physiological data based on at least a portion of the measurement environment data, generate integrated data of the first physiological data and the second physiological data based on at least one of comparing the first physiological data with the second physiological data and the measurement environment data, based on the first physiological data and the second physiological data being valid, and control a display to display the integrated data on the display.

A nursing monitoring device includes an inlet conduit with an inlet opening to enable milk that is released from a nipple to enter the inlet conduit. An outlet conduit with an outlet opening enables milk from the outlet conduit to enter a mouth of a nursing child. A measurement unit connected to the inlet conduit and to the outlet conduit enables measurement of a property of the milk that flows from the inlet conduit to the outlet conduit via the measurement unit. The outlet conduit is sufficiently long to enable placement of the measurement unit laterally to the mouth.

A method of monitoring a subject via a photoplethysmography (PPG) sensor configured to detect and/or measure PPG information from the subject includes changing, via a processor, signal analysis frequency of the PPG sensor signals, optical wavelength emission of the PPG sensor, and/or PPG sensor interrogation power at predetermined times. Each predetermined time is associated with measuring at least one different biometric parameter from a plurality of biometric parameters.

The present invention relates to systems and methods or wide-field polarized imaging of the skin. Preferred embodiments of the invention provide quantitative characterization of collagen structures in the skin and can be used to monitor skin treatment. A preferred embodiment can comprise a handheld imaging device that generates polarized images at different depths beneath a dermal surface and a data processor to process image data.

An apparatus comprises an activity monitor for measuring physical activity of a subject. The activity monitor is configured to obtain a first set of physical activity data over a first time period, for example during the day, and a second set of physical activity data over a second time period, for example during the night. A processor processes the data obtained by the activity monitor to calculate a physical activity ratio which is the ratio of the physical activity measured during the first time period to the physical activity measured in the second time period. The processor also calculates a first overall value which represents an activity level of the subject during the first time period. The physical activity ratio together with the first overall value may be used to assess the severity of symptoms of COPD displayed by a subject or to identify respiratory disease comorbidity information for example psychological issues such as low motivation, or sleep quality issues displayed by the subject.

An oximeter probe that takes into account tissue color (e.g., skin color or melanin content) to improve accuracy when determining oxygen saturation of tissue. Light is transmitted from a light source into tissue having melanin (e.g., eumelanin or pheomelanin). Light reflected from the tissue is received by a detector. A compensation factor is determined to account for absorption due to the melanin. The oximeter uses this compensation factor and determines a melanin-corrected oxygen saturation value.

The disclosure relates to methods, devices, and systems to identify a user of a wearable fitness monitor using data obtained using the wearable fitness monitor. Data obtained from motion sensors of the wearable fitness monitor and data obtained from heartbeat waveform sensors of the wearable fitness monitor may be used to identify the user.

There is provided a biological signal processing apparatus. The biological signal processing apparatus includes a biological signal extraction unit (2) configured to extract a biological signal from an electrocardiographic waveform measured by an electrocardiograph (1), an averaging processing unit (3) configured to calculate averaged data using time-series data of the biological signals extracted by the biological signal extraction unit (2), an abnormal value determination unit (4) configured to determine, for each data, whether the data of the biological signal extracted by the biological signal extraction unit (2) is appropriate, based on the averaged data calculated using the data of the biological signals that have occurred before the data, and an abnormal value processing unit (5) configured to perform one of deletion and interpolation of the data of the biological signal determined to be inappropriate by the abnormal value determination unit (4).

Systems, methods, and devices relate to monitoring biological conditions (e.g., vital signs) using patient-specific ranges. An example method includes receiving, from a sensor, first measurements of a vital sign of an individual determined automatically during a first time period and determining a baseline of the vital sign based on the first measurements by averaging the first measurements. A threshold of the vital sign can be a predetermined percentage of the baseline. Second measurements of the vital sign can be received from the sensor. In response to determining that at least one of the second measurements is outside of the range, an alarm may be triggered.

Systems and methods for quantitatively imaging retinal blood vessel oxygen saturation using retinal auto-fluorescence (AF) are provided. One or more excitation sources can be used to provide light to the retina, and retinal AF can be detected by one or more detectors. The quantitative level of oxygen saturation in the blood can be determined based on the intensity of AF.
