US 2021/0232191 A1 · POWER SOURCE TIME DIVISION MULTIPLEX FOR THERMAL MANAGEMENT AND EXTENDED OPERATION

Abstract

A method and apparatus may be used for power source time division multiplex for thermal management and extended operation. The apparatus includes a primary power source, a secondary power source, and a processor. The processor obtains an internal temperature measurement of the image capture device. The processor may determine a thermal zone based on the internal temperature measurement. In an example where the determined thermal zone is a first thermal zone, the processor may be configured to draw power from the secondary power source. In an example where the determined thermal zone is a second thermal zone, the processor may be configured to alternately draw power from the primary power source and the secondary power source. In an example where the determined thermal zone is a third thermal zone, the processor may be configured to draw power from the secondary power source.
