A first test strip channel provided in the base can have a main channel portion extending generally parallel with the base plane, and an angled channel portion that forms an angle with the main channel portion between 5 degrees and 90 degrees. The first test strip channel can house a biological test strip oriented so that a meter connecting end of the biological test strip is adjacent to the main channel portion and a sample end of the biological test strip is adjacent to the angled channel portion.

An exercise feedback system calibrates sensors of an athletic garment worn by an athlete while performing exercises. The sensors can record physiological data such as muscle activation. The system instructs the athlete to perform a calibration workout. The system generates a calibration value based on physiological data from the calibration workout and/or user information. The calibration value indicates, for example, the predicted maximum amplitude for the muscle activation of a particular muscle group (for example, glutes, hamstrings, or quadriceps) of the athlete. The system can update the calibration value over time as the system receives additional physiological data from subsequent exercises performed by the athlete. The system may determine a confidence level of the calibration value and may update the calibration value if the confidence level becomes too low. The system provides biofeedback to the athlete generated based on the calibration value.

In one or more embodiments, a base unit of a wearable device for continuous analyte monitoring may include sensor memory circuitry and a sensor assembly. The sensor memory circuitry stores information (data) of at least one parameter of at least one component of the base unit, such as, e.g., the sensor assembly. The base unit is configured to couple to a transmitter unit of the wearable device and to transfer the information to the transmitter unit. Analyte determinations are made based at least in part on the information. Numerous other embodiments are provided.

Apparatus, including an enclosure having a base and a cover with respective conductive layers. The conductive layers connect to form a shield attenuating electromagnetic radiation originating outside the enclosure in a range of 10 kHz-100 kHz by at least 20 dB within the enclosure. An adapter circuit within the enclosure processes electrophysiological signals to generate an output signal. A first connector passing through the enclosure connects to a probe to receive the electrophysiological signals and convey them to the adapter circuit. A second connector passing through the enclosure receives the output signal from the adapter circuit and conveys it to a console. A control input receives a control signal indicative of a frequency within the range, and a sensing circuit senses a magnetic field within the enclosure and outputs a warning signal when the magnetic field at the frequency indicated by the control signal exceeds a preset threshold.

A patch-type sensor module is provided. A patch-type sensor module according to one embodiment of the present invention comprises: a power supply unit electrically connected with a flexible circuit board; a sensing unit which is mounted on the flexible circuit board and includes a temperature sensor for measuring a user's body temperature; a communication unit which allows power to be supplied using a wake-up function, wherein a pairing with an external communication module is concurrently established when power is supplied, and information measured through the sensing unit is then transmitted to the external communication module; a control unit for controlling operations of the power supply unit, the sensing unit, and the communication unit; and a protection member for preventing the flexible circuit board, the power supply unit, the sensing unit, the communication unit, and the control unit from being exposed to the outside.
