Abstract: This disclosure describes techniques for reducing power consumption of a display device. According to these techniques, a display device is configured to determine whether an image to be displayed by the display device has become static. In response to identifying such a static image, the display device may operate in a static image mode. According to the static image mode, the display device may read a current frame of image data, modify the current frame of image data to generate a modified frame of image data with a reduced size, and store the modified image data in memory. The display device may read the modified image data from memory to present the static image, which may reduce power consumption of the display device.

Abstract: A method for determining touch input data complexity and negotiating the processing of touch inputs from a touchscreen controller to a host processor. As touch input data is received from a touchscreen, the data may be evaluated by the touchscreen controller to determine the data's complexity. When the touchscreen controller determines the received touch input data is too complex for touchscreen controller processing, the host processor may be requested to process the data. The touchscreen controller may resume processing touch input data based on low complexity or host processor availability. Complexity may be determined based on evaluations of the number and frequency of touch inputs. Additionally, the touch input data may be evaluated to determine whether it represents multi-touch input. In an aspect, the touchscreen controller may disregard received touch input data determined to be noise.

Abstract: This disclosure relates to techniques for performing display mode based video encoding to reduce power consumption in a source device of a Wireless Display (WD) system. More specifically, the techniques enable the source device to select an encoding process based on whether the video data to be encoded is in a static display mode or a dynamic display mode. For example, when the video data is in the static display mode, the source device selects a static encoding process that reduces an amount of video data processing and compression, which in turn reduces power consumption at the source device. When the video data is in the dynamic mode, the source device may select a conventional dynamic encoding process. The source device encodes the video data according to the selected encoding process, and transmits the encoded video data to one or more sink devices in the WD system for display.

Abstract: An apparatus includes multiple microphones and a controller. The controller is coupled to receive a signal from each of the multiple microphones. The controller is configured to control a transition of the multiple microphones from an active mode to a dormant mode. When the multiple microphones are in the active mode, the controller is configured to perform signal processing responsive to signals received from at least two of the multiple microphones. When the multiple microphones are in the dormant mode, the controller is configured to select a microphone of the multiple microphones and to perform signal processing corresponding to the selected microphone while suspending signal processing corresponding to unselected microphones.

The second sensor is deactivated when the first sensor is operating in the active mode. The apparatus includes logic to activate the second sensor when the first sensor transitions from the active mode to the dormant mode.

The electronic device performs the resource management operation based on the pause duration.

Abstract: A source device in a wireless display system determines whether a scene change has occurred between a first picture and a second picture prior to transmitting an encoded representation of the second picture to a sink device. The scene change occurs when the first picture and the second picture are sufficiently dissimilar. The source device may reduce, in response to determining that the scene change has occurred, a number of coding bits in the encoded representation of the second picture. Furthermore, in response to determining that the scene change has occurred, the source device increases a throughput of a wireless channel. After reducing the number of coding bits in the encoded representation of the second picture and increasing the throughput of the wireless channel, the source device transmits the encoded representation of the second picture to the sink device via the wireless channel.

Abstract: Various embodiments of methods and systems for managing battery load in a portable computing device (“PCD”) are disclosed. One such method includes tracking an active load on a battery attributable to one or more active power consuming components. Measurements associated with the battery and indicative of the battery's state of health may also be monitored. When a call for additional load on the battery is recognized, such as a user request for provision of additional functionality in the PCD, a future load on the battery that considers the newly called load can be calculated. Based on an analysis of the impact on the battery's state of health, existing, lower priority loads may be scaled or suspended to create battery load capacity for the newly called load. In this way, quality of service and user experience may be optimized while minimizing conditions that could be detrimental to the battery.

Processing capacity of a second processor, such as a high performance processor, may be distributed along with the data input when the available processing capacity of the first processor are insufficient to meet the processing capacity requirement and process the predicted feature event.

Abstract: In general, this disclosure relates to techniques for management of a multimedia connection between a wireless communication device (WCD) and one or more output devices. The connection may be a multimedia interface connection with content protection, e.g., High Definition Multimedia Interface (HDMI). In some cases, the multimedia interface connection with content protection may be inactive because the output device is no longer connected or the multimedia application is stopped or paused. The techniques include detecting a use mode of the multimedia interface connection with content protection between the WCD and one or more output devices. When the use mode of the multimedia interface connection with content protection is inactive, the WCD may reduce at least one of content processing or content protection processing. In this way, the techniques may reduce battery power consumption from multimedia processing by the WCD.
