Abstract: This invention is directed to defining quick groups for easily associating keywords with an object (e.g., a media objection) accessible using an electronic device. The user of an electronic device may define several keywords that identify attributes of an object accessible using the electronic device. The user may associate keywords with an object to link the attribute of the keyword with the object (e.g., associate a keyword entitled “vacation” to vacation pictures). The user may assign a shortcut key to each of a subset of the keywords, referred to as quick groups, by which the user may rapidly associate the keyword to an Object. In some embodiments, the electronic device may select the shortcut key of a quick group from the letters of the quick group to help the user remember the shortcut key.

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: Methods and systems for managing To do items and/or notes and/or emails (or other electronic messages) are described. A record, such as a To do item, in a database maintained locally by the data processing system is encoded into metadata. The metadata is sent as a false email message by an email client application executing on the data processing system to a remote email message server. An email client application executing on a remote processing system accesses the email message server and receives the false email message containing the metadata. The remote client application then either converts the metadata back into a database record editable at the remote processing system or presents a non-editable view of the database record, for example as an incoming email message.

Abstract: An environmental seal is formed around a square sensor disposed beneath a circular button cap within a button assembly. The button assembly includes shelf portions each extending separately into the interior of the assembly from a sidewall of the assembly. Portions of the sidewall are exposed between the shelf portions large enough to permit the four corners of the square sensor to contact the sidewall. The button cap is set above the sensor, resting upon the shelf portions. A first sealant bonds the top faces of the shelf portions to the bottom of the button cap. A second sealant bonds the edges of the sidewall to the corners of the sensor. The second sealant interfaces with the first sealant to form a complete environmental seal.

Abstract: An electronic device may be provided with a display mounted in a housing. The display may have an array of display pixels that provide image light to a user. The array of display pixels may form an active display structure with a rectangular shape. The rectangular active display structure may be surrounded by an inactive border region. Optical structures such as upper structures formed from a sheet of glass and lower optical structures that lie beneath the sheet of glass may be configured to bend light from the display pixels along the periphery of the active display structure. The upper optical structures may have an area that is larger than the area of the active display structure, so that the presence of the optical structures may serve to enlarge the apparent size of the display. The lower and upper optical structures may have curved surfaces for bending the light.

Abstract: In order to flexibly manage and broadcast content to electronic devices in a multicast group, a multicast group management protocol allows one or more multicast group masters to be specified. In addition to controlling membership in the multicast group, a multicast group master can define or specify a multicast session, in which content from one or more sources is broadcast to at least a subset of the electronic devices or sinks in the multicast group. The multicast group management protocol supports concurrent broadcasts of content to different multicast sessions. Moreover, the broadcasts in the different multicast sessions may have different: priorities, encoding techniques, quality-of-service policies, reliability, and/or number of parity bits. For example, the different encoding techniques may include different layers in H.264 Scalable Video Coding. Alternatively or additionally, the different number of parity bits may be associated with application layer forward error correction.

Abstract: A force applied to a force-sensing touch screen device may be determined as follows. A deformation sensing layer of the device may measure an actual deformation of a touch screen of the device. A force sensor of the device may measure a sensed force applied by the touch screen to the force sensor of the device. A processor circuit of the device may determine an expected deformation expected to be imparted to the touch screen by the sensed force. The processor circuit may determine a virtual deformation based on the expected deformation due to the sensed force and the measured actual deformation. The virtual deformation may indicate the force applied to the force-sensing touch screen.

Abstract: An illuminator may be coupled to the key cap of a key. The key cap may include a portion that is operable to be illuminated and one or more illuminators may be coupled thereto. In particular embodiments, keys may include power delivery systems that are operable to wirelessly transmit power from a power source to illuminators. Such power delivery systems can include inductive transmitters and/or receivers, ultrasonic transmitters and/or receivers, laser diodes and photodiodes, electrodes that capacitively couple to wirelessly transfer power, and so on. In various embodiments, keys may include interconnects that connect an illuminator with a power source. The interconnect may be a flexible material that includes one or more traces and is configured with a shape that bends and twists to allow movement without stretching. The interconnect may also be part of a movement or support mechanism of a key.

Abstract: An electronic device may have a display. The device and display may bend about a bend axis. The display may have layers such as an organic light-emitting diode layer or other layer with pixels, a touch sensor layer, a protective layer with a polarizer, and a support layer. Lubrication layers formed from textured surfaces, slippery coatings, and lubricants such as oil may be interposed between the layers of the display so that the display layers slip past each other during bending of the device and display and minimize display stress. A device housing may have a recess or other structures that retain the display within the housing while allowing the display layers to shift relative to each other during bending. Elastomeric gaskets and elastomeric lubricant retention structures may be used to mount the display layers in the housing and to retain liquid lubricant within the layers of the display.

Abstract: Messaging between a companion device and an accessory device is controlled such that different modes of communication may be utilized. The different modes can implement different messaging strategies, each of which is intended for efficient power management, in view of the limited electrical power that is typically available at the accessory device. A received request message for sending from the companion device to the accessory device is sent if predetermined conditions apply, and similarly for messages from the accessory device to the companion device.

Abstract: The systems described herein include a universal browse and watch list that can provide a centralized user interface for presenting recently watched, recommended, and continue watching content items provided by different content providers. For example, a media device can include multiple content provider applications for viewing media items on the media device. When a content provider application presents a media item, the content provider application can send playback status data to a content aggregator application on the media device. The content aggregator application can provide the playback status data to a content aggregator server. The content aggregator application can interact with a content aggregator server to determine which content providers can provide the played media item or related media items. The content aggregator application can provide a centralized user interface that allows the user to initiate playback of media items provided by the various content providers.
