Abstract: Methods and apparatus are disclosed for battery current monitoring. A current controller can prevent injury from a battery operated wearable device. An isolation switch can interrupt delivery of current of a battery to a load in response to an isolation switch control signal to prevent burn injury to a wearer of the battery operated wearable device. The battery operated wearable device can be wrist wearable or head wearable.

Abstract: Implementing over-temperature fault protection in wearable devices and other electronic devices may be performed using an example apparatus including a voltage source; a thermistor bias network to, when enabled, output a thermistor voltage; an over-temperature determiner to enable the thermistor bias network; and, when the thermistor voltage corresponds to a temperature above a maximum temperature threshold, output a fault; and an isolation transistor to couple the voltage source to a system; and when the over-temperature determiner outputs the fault, decouple the voltage source from the system.

Abstract: Apparatuses, methods and storage medium associated with restricting current draw in wearable devices are disclosed herein. In embodiments, a wearable computing device may include a power source, one or more components coupled with each other and to the power source to perform wearable computing; and control circuitry coupled with the one or more components, the control circuitry to: identify a threshold selected based on a power consumption model of the wearable computing device; ascertain whether current draw from the power source is greater than the threshold; and restrict the current draw from the power source of the wearable computing device based on a signal output from one of the one or more components, in response to the current draw is ascertained to be greater than the threshold. Other embodiments may be disclosed or claimed.
