Description
The present disclosure relates to a power supply system, in particular to, a head mounted wearable device power supply system.
Head mounted wearable electronic devices (HMWDs), including, e.g., head mounted displays (HMDs), may be powered by rechargeable batteries. For a given battery technology, as battery capacity increases, battery size (and weight) also increases. Batteries used to power HMWDs are limited in size and weight due, at least in part, to user comfort considerations. Such batteries may be similarly limited in capacity that may limit a time duration of operation of the HMWD between charges.
Features and advantages of the claimed subject matter will be apparent from the following detailed description of embodiments consistent therewith, which description should be considered with reference to the accompanying drawings, wherein:
FIG. 1A illustrates a functional block diagram of a head mounted wearable device (HMWD) power supply system consistent with various embodiments of the present disclosure;
FIG. 1B is a sketch of a loosely coupled configuration consistent with various embodiments of the present disclosure;
