A system includes an electronic circuit, a memory, and a control system. The electronic circuit is coupled to a conduit. The conduit may be configured to deliver pressurized air. A portion of the electronic circuit has a first electrical property that is configured to change based at least in part on movement of the portion of the electronic circuit. The memory stores machine-readable instructions. The control system includes one or more processors configured to execute the machine-readable instructions. Data associated with the first electrical property of the electronic circuit is received. The received data is analyzed. Based at least in part on the analysis, it is determined that the first electrical property of the electronic circuit has changed. Responsive to the determination that the first electrical property of the electronic circuit has changed, it is determined that the conduit is moving or has moved.

A method for ambient mobility testing, the method including: collecting data associated with an individual's movement, via at least one sensor; analyzing the collected data to determine timed-up-and-go (TUG) actions of a TUG test; determining results of a complete TUG test; and providing the results of the TUG test.

The present disclosure pertains to a wearable electronic device for the novel sensing of physiologically presented symptoms of stress corresponding to changes in a finger skin temperature biomarker.

A device and system for promoting more recuperative sleep by regulating a user's body temperature. This may be done by using a series of devices that measure information about the user both while they are awake and while they are asleep, communicate that information to a processing unit, and create an ideal body temperature range profile based on that information. A temperature stimulus device may ensure that the core body temperature of the user stays substantially within the ideal body temperature range. By keeping the core body temperature of the user within the calculated range, the device and system will ensure deeper, and therefore more recuperative, sleep.

A wearable device for tracking swim activities of a user is provided. The wearable device may include one or more sensors configured to generate sensor data, and based on the sensor data, the wearable device may determine swim metrics such as swim stroke count, swim stroke type, swim lap count, and swim speed. The determined swim metrics may be filtered based on one or more swim periods during which the user is likely to have been swimming. The wearable device may determine such swim periods based on the sensor data and/or the determined swim metrics.

In an aspect, this disclosure relates to methods and devices for calibration of capillary blood flow meters for measuring capillary blood flow in absolute flow units (such as mL/min×100 g of tissue). For example, the calibration method utilizes the combination of a wet model device and a dry model device to provide a convenience, easy-to-use, and accurate calibration and measurement in absolute flow units. In an aspect, the dry model device can use thermal conductivity parameters from the wet model device, which can be translated into thermal conductivity parameters in a dry model device, which can be used to calibrate the capillary blood flow meter in absolute units.

A ring for photoplethysmographic sensing performs transmissive PPG and/or reflective PPG. It can enable lower power consumption, higher fidelity, and/or greater versatility to different use cases and users' specificities. The PPG system takes advantage of sensor spatial diversity to enhance the quality and the reliability of the PPG measurements in smart rings, for example. It can also perform user identification.

The invention relates to a spirometer (1) comprising a MEMS-based thermal fluid flow sensor (13, 13.1, 13.2) for generating a signal in response to a fluid flow generated during inhalation or exhalation; and a microcontroller (14) for calculating the fluid flow from the signal generated by the flow sensor (13, 13.1, 13.2). The spirometer (1) may be connected to other devices, such as a smartphone or a personal computer or any other computing unit which is adapted to collect, store, analyse, exchange and/or display data. The invention further describes the use of the spirometer (1) in measuring a user's lung performance and/or monitoring it over time. Furthermore, the spirometer (1) may be provided in a system together with an air quality measurement device for determining the air quality at a location of interest; and a computing unit for collecting, analysing and correlating the user's lung performance data obtained from the spirometer (1) with the air quality data, and optionally geolocalisation data of said location.
