Abstract: A device, such as an autonomous mobile device (AMD), includes sensors such as a camera. Multiple applications executing on the device may concurrently use sensor data from a single shared sensor. For example, a first application may use image data to localize the AMD while a second application uses the image data to recognize users. The first application and the second application may have different parameters for operation of the sensor or resulting sensor data, such as different image resolutions and frame rates. An arbitrator system manages these different parameters, and may also provide sensor data to the respective application that is consistent with the application's parameters. For example, different resolutions of image data may be provided to different applications based on their parameters.

Abstract: Devices, systems and methods are disclosed for readying a device from hibernation with reduced user-perceived latency. For example, data likely to be accessed may be selected as preload data that is loaded into volatile memory prior to the device resuming system interactivity (e.g., being responsive to user input), thus “anticipating” user demand by loading memory pages that the user will likely request. The device may determine additional data to add to the preload data based on processes running on the device and virtual memory areas (VMAs) associated with the processes, may weight the processes and may intelligently determine the data so that the device more rapidly reaches system interactivity.

Abstract: Devices, systems and methods are disclosed for limiting a number of hibernations based on a finite lifetime expectancy of nonvolatile memory. As the nonvolatile memory has a finite lifetime expectancy, a device may determine cumulative thresholds and associated session thresholds and may limit a frequency that the device hibernates. For example, the device may determine a cumulative number of hibernations and associate the cumulative number of hibernations with a cumulative threshold. The device may determine a session threshold corresponding to the cumulative threshold and may limit a number of hibernations using the session threshold. For example, the device may enter a hibernation state up to the session threshold and thereafter may enter a suspended state instead.
