Methods and apparatuses for athletic performance and technique monitoring are disclosed. In one example, a sensor output is received associated with a movement of a user torso during a running motion. The sensor output is analyzed to identify an undesirable torso motion.

A method of determining one or more vital sign parameters by a wireless vital-sign measurement device comprises: measuring motion information of a user wearing the wireless measurement device, the measurement device being in the idle mode in which at least one opto-electronic sensor in the measurement device is deactivated; switching the measurement device in an active mode if the motion information is below a predetermined threshold, wherein in the active mode the at least one opto-electronic sensor is activated; during a predetermined measuring period, exposing part of a skin tissue of the user to light and measuring one or more optical response signals associated with the exposed skin tissue and the motion sensor measuring motion information associated with movements of the user; and, selecting or rejecting one or more pulses in the one or more optical response signals on the basis of the motion information measured during the measuring period and determining one or more vital sign parameters on the basis of the one or more selected pulses.

Examples described herein include sensor devices for measuring a parameter of a user. The sensor devices may include a reusable portion (e.g., a sensor). The sensor devices may include one or more weakened portions that may fracture on removal of a portion of the sensor device from the user. Fracturing the weakened portions may expose the reusable portion (e.g., the sensor). Accordingly, the reusable portion may be more readily observed and collected for reuse.

Exemplary embodiments described in this disclosure are generally directed to systems and methods for detecting alertness of a driver of a vehicle. In one exemplary method, a driver alertness detection system determines whether a driver of a vehicle is susceptible to lagophthalmos. If the driver is susceptible to lagophthalmos, the driver alertness detection system may evaluate an alertness state of the driver by disregarding an eyelid status of the driver and monitoring biometrics of the driver such as, a heart rate and/or a breathing pattern. Alternatively, the driver alertness detection system may evaluate an alertness state of the driver by placing a higher priority on the biometrics of the driver than on the eyelid status. However, if the driver is not susceptible to lagophthalmos, the driver alertness detection system evaluates the alertness state by placing a higher priority on the eyelid status than on the biometrics of the driver.

In certain examples, methods and structures are directed to an apparatus having a plurality of stretchable leads, with each of the plurality of stretchable leads including an associated electrode which is to receive electrical signals generated in response to a subject-s heart and to pass the received electrical signals along a respective one of plurality of stretchable leads. The apparatus also includes a patch integrating the stretchable substrate with the plurality of stretchable leads and with the patch having an area for circuitry to reside for collecting the electrical signals passed along each of the plurality of stretchable leads, wherein each of the plurality of stretchable leads is to be on a subject side of the patch. In more particular examples, the circuitry is used to provide a multi-lead ECG based on the electrical signals.

A biological information collection sensor unit includes sensors and a processor. Each sensor has a light emitter emitting near-infrared or infrared light and a light receiver collecting transmitted light including at least light transmitting through a measurement target tissue. The sensors are arranged on surfaces of a measurement target region and configured to collect optical information regarding tissues of the measurement target region. The processor calculates tissue oxygen saturation information regarding oxygen saturation of the tissue based on the optical information. The sensors are arranged in different areas of the measurement target region. The processor includes an arithmetic processor to calculate the tissue oxygen saturation information for each sensor and a notifier to output a notification signal when the number of the sensors collecting the optical information used to calculate the tissue oxygen saturation information equal to or greater than a preset threshold satisfies a specified condition.

According to certain embodiments, an electronic device comprises: a sensor module; a communication module; and a processor operatively connected to the sensor module and the communication module, wherein the processor is configured to: measure a body temperature of a user through the sensor module, thereby resulting in a measured body temperature, estimate a core body temperature of the user, based on the measured body temperature, and provide body temperature information of the user, based on the core body temperature, wherein the measured body temperature comprises a shell temperature of a body part making contact with the electronic device, and wherein the core body temperature comprises a core temperature of an internal organ of a body of the user.

A device for monitoring one or more health conditions of a subject in need thereof has a plurality of sensor arrays adapted to detect, from a skin surface of the subject, a plurality of volatile organic compounds (VOCs), one or more vital signs, or both, and to generate electrical signals; one or more processors for processing the electrical signals from the plurality of sensors, generating data, and diagnosing one or more health conditions of the subject by correlating the generated data with the one or more health conditions; an interface for outputting data and/or receiving input commands; and a fixing member for placing the device to the skin surface of the subject.

Systems and method for monitoring patient physiological data are presented herein. In one embodiment, a physiological sensor and a mobile computing device can be connected via a cable or cables, and a processing board can be connected between the sensor and the mobile computing device to conduct advanced signal processing on the data received from the sensor before the data is transmitted for display on the mobile computing device.
