Abstract: A device implementing a system for displaying an image includes a processor configured to, generate, during a first power state of a device, a data structure specifying image frames and a respective display time for each of the image frames, and retrieve, during a second power state of the device and from the data structure, an image frame based on the respective display time for the image frame. The at least one processor is further configured to display, during a third power state of the device, the retrieved image frame on a display of the device.

Abstract: Aspects of the subject technology relate to providing frame rate arbitration for electronic devices. Frame rate arbitration can include determining a global frame rate based on frame rate parameters from one or more animation sources, and providing the global frame rate to the animation sources. The frame rate parameters for various animations sources can have differing preferred, minimum, and/or maximum frame rates, and the global frame rate may be determined for concurrent display of multiple animations from the multiple animation sources. In one or more implementations, frame rate arbitration can also be performed based on frame rate parameters from an input source.

Abstract: Disclosed herein is a technique for implementing a secure lock screen on a computing device. The secure lock screen is configured to permit particular applications to display their content—such as main user interfaces (UIs)—while maintaining a desired overall level of security on the computing device. Graphics contexts, which represent drawing destinations associated with the applications, are tagged with entitlement information that indicates whether or not each graphics context should be displayed on the computing device when the computing device is in a locked-mode. Specifically, an application manager tags each application that is initialized, where the tagging is based on a level of entitlement possessed by the application. In turn, a rendering server that manages the graphics contexts can identify the tagged entitlement information and display or suppress the content of the applications in accordance with their entitlements.

Abstract: A device implementing a system for power management includes at least one processor configured to, detect first gesture state associated with motion of a device, the first gesture state being associated with meeting a first threshold of device motion, and set, in response to detecting the first gesture state, the device to a first power state. The at least one processor is further configured to detect, subsequent to detecting the first gesture state, a second gesture state associated with motion of the device, the second gesture state being associated with meeting a second threshold of device motion, and set, in response to detecting the second gesture state, the device to a second power state. The at least one processor is further configured to update, based on setting the device to the second power state, image data on a display of the device.
