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.

Abstract: Embodiments herein relate to the detection and switchable use of a detachable GNSS antenna with a wearable electronic device. In various embodiments, a wearable electronic apparatus may include a multi-band antenna to receive satellite positioning signals in a first frequency band and local radio frequency communication signals in a second frequency band, an antenna connector to optionally receive a detachable satellite positioning antenna, and a switch having a switching terminal, a first input terminal coupled with the multi-band antenna, a second input terminal coupled with the antenna connector, and an output terminal, wherein the switch is to selectively connect the first input terminal or the second input terminal to the output terminal, in response to a state of a switching signal received at the switching terminal. Other embodiments may be described and/or claimed.
