  • MULTIPLE ASYMMETRIC BATTERIES ARCHITECTURE FOR HEAD-WEARABLE DEVICES, AND SYSTEMS AND METHODS OF USE THEREOF
    Publication number: 20260099056
    Abstract: A head-wearable device comprising a larger battery, a smaller battery, one or more electronic components, and memory including executable instructions for causing the head-wearable device to perform operations is described. The operations are performed in response to a request to perform a computational task. The operations include, in accordance with a determination that a larger battery charge is above a larger battery charge threshold and a smaller battery charge is above a smaller battery charge threshold, providing power from the larger battery and the smaller battery to the one or more electronic components. The operations further include, in accordance with a determination that the larger battery charge is above the larger battery charge threshold and the smaller battery charge is below the smaller battery charge threshold: (i) deactivating a discharging path of the smaller battery and (ii) providing power from the larger battery to the one or more electronic components.

  • MITIGATION OF LIGHT EMITTING DIODE (LED) DISPLAY DRIVER INPUT PEAK POWER IN AUGMENTED REALITY (AR) / VIRTUAL REALITY (VR) DEVICES
    Publication number: 20250203731
    Abstract: A power management system for a display light emitting diode (LED) driver for an augmented reality/virtual reality (AR/VR) device mitigates (e.g., attenuates) an input peak power delivered to the LED driver from a DC source and decreases a voltage ramp rate of the LED driver while maintaining the default current ramp rate or vice versa. A liquid crystal on silicon (LCOS) digital process is used to provide a current reference with a slow ramp rate and/or to provide an offset. The offset (e.g., a delay) may be implemented between the voltage ramp and the current ramp to achieve a non-overlapping output voltage and output current.
