Abstract
Battery powered systems such as AR/VR/MR devices are space constrained due to which power monitoring of individual subsystems of such devices is not possible. Peak load management without such monitoring is a difficult task. This disclosure describes peak load power management techniques that utilize a power estimate for the battery in current operating conditions and a lookup table of different power states in various subsystems. The overall power requirement for the system in the current power state is compared with the power estimate. Brownouts are avoided by performing suitable state transitions for each subsystem such that the total power required by the system is less than the estimated peak power.
