Methods, systems, and devices for temperature calibration are described. A device may support temperature calibration for a set of temperature sensors. For example, a wearable device may activate a set of temperature sensors associated with the wearable device. The set of temperature sensors may include a primary temperature sensor and one or more secondary temperature sensors. The wearable device may determine a trigger to calibrate the one or more secondary temperature sensors based on one or more conditions, and calibrate the one or more secondary temperature sensors using the primary temperature sensor based on the trigger. Based on the calibrating, the wearable device may process temperature data associated with a user that is received from one or more of the primary temperature sensor or the one or more secondary temperature sensors.

Techniques for temperature measurement according to a calibrated temperature

Methods, systems, and devices for optical signal measurement are described. A wearable electronic device may activate a first combination of optical sensors, the first combination of optical sensors including a set of transmitter sensors and a set of receiver sensors. In some cases, one or more optical sensor of the first combination of optical sensors may be positioned under a protrusion on an inner surface of the wearable electronic device. The device may measure, at the set of receiver sensors at a first time, one or more signals from the set of transmitter sensors, determine a signal quality metric associated with the one or more signals, and select a second combination of optical sensors for use at a second time based on the signal quality metric.

Configurable photoplethysmogram system

The invention relates to a system for indicating information representing battery status of an electronic device. The system comprises a charging unit and an electronic device. The charging unit comprises charging means, wireless communication means, and indication means. The electronic device comprises a rechargeable battery, charging means, and wireless communication means. During the wireless charging of the electronic device, the electronic device is configured to detect information representing the battery status of said electronic device and to communicate the detected information representing the battery status to the charging unit, and the charging unit is configured to receive the information from the electronic device and to indicate at least part of the received information representing the battery status of the electronic device. The invention relates also to a method for indicating information representing battery status of an electronic device.

Techniques are presented for repetition on both uplink and downlink Slow Associated Control Channel (SACCH) channels. For instance, an exemplary method is disclosed that is performed by a mobile node. The method includes receiving from a network node a first block of data over a downlink SACCH channel, and storing the first block of data. The method also includes, subsequent to receiving the first block of data, receiving from the network node a second block of data over the downlink SACCH channel. The method further includes attempting to decode the second block of data. The method additionally includes, in response to a failure in the attempt to decode the second block of data, combining into a combination the second block with the stored first block of data. The method also includes attempting to decode the combination.
