Abstract: Head-mounted display systems with power saving functionality are disclosed. The systems can include a frame configured to be supported on the head of the user. The systems can also include a head-mounted display disposed on the frame, one or more sensors, and processing electronics in communication with the display and the one or more sensors. In some implementations, the processing electronics can be configured to cause the system to reduce power of one or more components in response to at least in part on a determination that the frame is in a certain position (e.g., upside-down or on top of the head of the user). In some implementations, the processing electronics can be configured to cause the system to reduce power of one or more components in response to at least in part on a determination that the frame has been stationary for at least a threshold period of time.

Abstract: A head mounted display system can process images by assessing relative motion between the head mounted display and one or more features in a user's environment. The assessment of relative motion can include determining whether the head mounted display has moved, is moving and/or is expected to move with respect to one or more features in the environment. Additionally or alternatively, the assessment can include determining whether one or more features in the environment have moved, are moving and/or are expected to move relative to the head mounted display. The image processing can further include determining one or more virtual image content locations in the environment that correspond to a location where renderable virtual image content appears to a user when the location appears in the display and comparing the one or more virtual image content locations in the environment with a viewing zone.

Abstract: Various embodiments relate to a thermal management system for an electronic device, such as an augmented reality or virtual reality device. The thermal management system can comprise an active cooling mechanism in various embodiments to dynamically or actively cool components of the device, for example, by adjust fan speeds of a fan assembly. In some embodiments, a hardware shutdown mechanism can be provided to shut down the device if software-based thermal management devices are inoperable. In some embodiments, the air flow into and/or within the electronic device can be adjusted to cool various components of the device.
