  • Patent number: 12253896
    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.

  • Publication number: 20250047909
    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.

  • Patent number: 12041309
    Abstract: In some implementations, a first device can record a display screen of a second device remotely. For example, the first device (e.g., a remote computing device) can receive information identifying other computing devices on a network. The first device can receive a selection of one of the other computing devices (e.g., the second device) and send a message to the second device to initiate a recording of the display screen of the second device. In response to receiving the message, the second device can record video frames of images presented on the display of the second device. The second device can send the video frames to the first device for display and/or storage. While recording the images presented on the display screen, the second device can present indicia on the display screen of the second device indicating that a screen recording is in progress.

  • Patent number: 11670252
    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.

  • Patent number: 11574066
    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.

  • Patent number: 11481096
    Abstract: This disclosure pertains to systems, methods, and computer readable medium for mapping particular user interactions, e.g., gestures, to the input parameters of various image processing routines, e.g., image filters, in a way that provides a seamless, dynamic, and intuitive experience for both the user and the software developer. Such techniques may handle the processing of both “relative” gestures, i.e., those gestures having values dependent on how much an input to the device has changed relative to a previous value of the input, and “absolute” gestures, i.e., those gestures having values dependent only on the instant value of the input to the device. Additionally, inputs to the device beyond user-input gestures may be utilized as input parameters to one or more image processing routines. For example, the device's orientation, acceleration, and/or position in three-dimensional space may be used as inputs to particular image processing routines.

  • Patent number: 11216287
    Abstract: Systems, methods, and computer readable media for selectively placing an application into a reduced-priority rendering mode during system user interface (UI) operations are described. Techniques disclosed herein transition an executing (foreground) application from a synchronous render mode (having a first render priority) to an asynchronous render mode (having a second, lower, render priority) when the system moves from supporting execution of the application into displaying a system UI. In this new state, the application's UI display element (e.g., an icon or reduced size viewing window) may continue to be updated (e.g., in accordance with the lower render priority) but does not interfere with the system UI's responsiveness.
