  • Patent number: 11575877
    Abstract: An eyewear device that adjusts an on time and an off time of a pair of cameras to control heat of the cameras and of the eyewear device. Each of the pair of cameras has a duty cycle determining when the respective camera is on and off. A camera control chart contains the duty cycles. The eyewear may have a temperature sensor such that the on and off times of the cameras are a function of the temperature sensor.

  • Patent number: 9665152
    Abstract: In embodiments of RFID-based power status and battery management, a mobile device includes a radio-frequency identification (RFID) tag that includes a memory to maintain context information associated with the mobile device. The mobile device includes a processing system to execute a power manager and to interface with the RFID tag via a communication bus. The power manager can determine a stowed context of the mobile device based on one or more sensors implemented in the mobile device, and communicate a stowed context indication of the stowed context of the mobile device to the RFID tag to be stored in the RFID tag memory. The power manager can also communicate a power-state indicator of a power on state or a power off state of the mobile device to the RFID tag to be stored in the RFID tag memory.
