Abstract: A regulator draws power from a battery or power delivery system and supplies regulated power to a load according to alternating modes of operation. In a voltage control mode, the regulator supplies power with a nominal voltage level and a fluctuating current level that is allowed to float according to the current demands of the load. When the load demands an amount of current that could potentially cause damage, the regulator transitions to a current control mode. In the current control mode, the regulator supplies power with a fluctuating voltage level and a maximum current level. The regulator transitions between voltage control mode and current control mode in order to supply a maximum power level to the load without exceeding the maximum current level. The regulator is also configured to limit the power drawn from the battery by decreasing the maximum output current, potentially avoiding voltage droop.

Abstract: Embodiments of the present invention are capable of lowering touch scan rates in a manner that conserves power resources without compromising performance or user experience thereby promoting battery life. Embodiments of the present invention perform touch scan operations using a touch sensitive panel at a first scan rate. In response to certain events automatically detected within the mobile device (e.g., when a full-screen video is being displayed), embodiments of the present invention may then perform touch scan operations at a second scan rate that is slower than the first scan rate that also consumes less power compared to the first scan rate. As such, for events or use cases in which limited user interaction with the touch sensitive panel is typical, embodiments of the present invention may lower touch scan rates in a manner that still enables users to interact with applications (e.g., interaction with playback controls during video playback) and promotes efficient power usage and extends battery life.

Abstract: An image capture application captures a sequence of images via a digital camera. The sequence of images may have undesirable levels of blurriness due to the motion of objects in the field of view of the digital camera or due to movement of the digital camera itself. A deblur engine within the image capture application generates image segments within one of the captured images, where a given image segment includes pixel values that move coherently between different images in the sequence. The deblur engine then deblurs each image segment based on the coherent motion of each different image segment and combines the resultant, deblurred image segments into a deblurred image. Advantageously, blurriness caused by the combined effects of moving objects and camera motion may be reduced, thereby improving the ability of a digital camera to provide high-quality images.
