The wearable device (10) comprises a liveness detection module (103) arranged to detect whether the wearable device (10) is being worn by a user. The wearable device (10) comprises an activation message module (105) arranged to generate an activation message for requesting that wireless network services be activated for the wearable device (10) in response to the liveness detection module detecting that the wearable device is being worn. The wearable device (10) comprises a communicator (107) arranged to transmit the activation message to a server operable to activate wireless network services for the wearable device (10). The wireless network services are to be activated for a first wireless network. The communicator (107) is arranged to transmit the activation message via a second wireless network that the wearable device (10) is activated to transmit data on.

This document discusses, among other things, systems and methods for managing pain of a subject. A system includes a first sensor circuit to sense a first signal indicative of a functional state of the subject, a second sensor circuit to sense a second signal different from the first signal, and a controller circuit. The controller circuit may determine an operating mode of the second sensor circuit according to the sensed first signal, trigger the second senor circuit to sense the second signal under the determined operating mode, and generate a pain score using at least the second signal sensed under the determined operating mode. The pain score may be output to a patient or used for closed-loop control of a pain therapy.

The described embodiments relate to a self-regulating patch for taking biopotential measurements and balancing accurate measurements and user comfort. The self-regulating patch including: a heating element operable to generate heat that causes formation of sweat at the skin surface; a biopotential sensor; an exterior surface constructed of a moisture wicking material enveloping the heating element; and a logic to concurrently activate the biopotential sensor and transition the self-regulating patch between a plurality of modes, including a comfort mode and an accuracy mode, where in the comfort mode the heating element is inactive and in the accuracy mode the heating element is active.

A method for treating episodes of apnoea and/or hypopnea is provided. The method has the steps of: a) detecting or predicting an episode of apnoea and/or hypopnea by means of at least one sensor selected from a respiratory pressure sensor, a pulse oximeter, an acoustic sensor and/or a respiratory temperature sensor; and b) emitting an electrical signal by means of an electrical actuator connected to at least one submental nerve and/or muscle, the electrical signal having a bipolar waveform and a frequency between 5 and 100 Hz.

Provided is an apparatus for managing a player with a guard including a sensor sensing a vital information of a player to calculate an injury risk of the player to thereby manage a condition of the player, the apparatus including: a communication unit receiving the vital information from the guard and transmitting the injury risk to the guard; a memory storing a program calculating the injury risk to manage the condition of the player; and a processor connected to the communication unit and the memory to execute an operation implemented by the program, in which the program may include instructions using the vital information and pre-stored vital recovering ability data of the player to calculate the injury risk of the player.
