Abstract: Systems and methods for power management are disclosed herein. In one disclosed embodiment, a battery charging system includes a battery charger for simultaneously charging a battery (and/or providing power to a system load) with multiple power sources, using a closed-loop charging servo target based on measurements taken by one or more gauges. In some embodiments, the multiple power sources may be utilized simultaneously according to a charging profile that specifies, e.g., one or more battery charging parameters, as well as according to determined priority levels for one or more of the multiple power sources coupled to the battery. In some embodiments, the priority level of a given power source is not fixed; rather, the priority level for the given power source may change based upon the characteristics of the given power source. In some embodiments, the priority levels for the multiple power sources are implemented using cascaded voltage target values.

Abstract: An audio amplifier has a first H bridge and a second H bridge, to drive a speaker as a load. The second H bridge drives the speaker through resistors for increased output impedance. Control logic operates the first H bridge as a class D amplifier for larger amplitudes of audio signal, and operates the second H bridge as a class D amplifier for smaller amplitudes of audio signal. Other aspects are also described and claimed.

Abstract: Power consumption of touch sensing operations for touch sensitive devices can be reduced by implementing a coarse scan (e.g., banked common mode scan) to coarsely detect the presence or absence of an object touching or proximate to a touch sensor panel and the results of the coarse scan can be used to dynamically adjust the operation of the touch sensitive device to perform or not perform a fine scan (e.g., targeted active mode scan). In some examples, the results of the coarse scan can be used to program a touch controller for the next touch sensing frame to idle when no touch event is detected or to perform a fine scan when one or more touch events are detected. In some examples, the results of the coarse scan can be used to abort a scheduled fine scan during the current touch sensing frame when no touch event is detected.

Abstract: The systems described herein provide a remote keyboard service for a media device on a computing device without having to invoke an application or unlock the computing device. The computing device can receive a message indicating that a text input field on the other device is selected and present a notification to the user prompting the user to invoke the virtual keyboard on the computing device to provide text input to the selected text input field. The computing device can receive user input selecting the notification and present a virtual keyboard for providing text input to the other device. The computing device can receive keyboard input from the user selecting characters and send the characters to the other device. The other device can then user the characters as text input to the selected text input field.

Abstract: The techniques utilize a user's recommendation data to choose a presentation template. Each presentation template includes a plurality of media asset slots, each of which is associated with a certain type of media asset. For example, each media asset slot generally may be assigned to a playlist, album, composer, or music video. Further, each of these general assignments may further specify that the playlist, album, composer, or music video be from a known artist, familiar artist, recommended artist, or unknown artist, for example. Once the appropriate presentation template has been chosen along with the recommended media content for each of the plurality of media asset slots, the media asset slots are associated with the selected media content.

Abstract: The described embodiments transfer an activity from a source electronic device to a companion electronic device. The source electronic device receives activity information describing an activity performed in a first application at the source electronic device and broadcasts an activity advertisement comprising an activity identifier for the activity. Upon receiving the activity advertisement, the companion electronic device determines whether a second application that is associated with the first application is available at the companion electronic device. If the second application is available, the companion electronic device acquires extended activity data from the source electronic device and uses the extended activity data to configure the second application and commence performing the activity with the second application at the companion electronic device. The source electronic device may also forward activity-related information (e.g.

Abstract: Techniques for bonding structural features together in an enclosure of an electronic device are disclosed. A structural feature may be ultrasonically soldered to the enclosure to provide structural support and form a magnetic circuit within the device. Also, ultrasonic welding can bond various features to an interior region of the enclosure without leaving a mark or trace to an exterior region of the enclosure in a location corresponding to the various features. Further, one or more features can be actuated against the enclosure to bond the one or more features by friction welding. In addition, a rotational friction welding machine can rotate a feature having a relatively small diameter at relatively high speeds against the enclosure to drive the feature into the enclosure and frictionally weld the feature with the enclosure. Also, the friction welding does not leave any an appearance of cosmetic deformation on the exterior region.

Abstract: Systems, methods, and devices are provided for reducing and/or eliminating impact of inter-carrier interference on wireless signals transmitted and received via off-grid radio communications (e.g., Device-to-Device (D2D) communication).

The method may also involve generating an asymmetrical frequency spectrum for a portion of the plurality of subcarriers centered about the removed null subcarrier. The method may also include transmitting the plurality of subcarriers to another electronic device via D2D communication.

Abstract: A charging station for an electric vehicle includes a passive alignment mechanism that includes a longitudinal translation stage that allows motion in a longitudinal direction, a charging plug connected to the passive alignment mechanism, and a releasable connector. The releasable connector resists motion of the longitudinal translation stage in a connected position when a magnitude of an external force applied in the longitudinal direction is below a threshold. The releasable connector moves from the connected position to a released position to allow motion of the longitudinal translation stage when the magnitude of the external force applied in the longitudinal direction is above the threshold.
