Abstract: Systems for harnessing power through electromagnetic induction utilizing printed coils are provided. A system can include one or more moveable magnets adjacent to printed coils on a circuit. For example, a system can include one or more magnets that are operative to move alongside a circuit board that includes printed coils. The one or more magnets may move, for example, when a user shakes the system or when the user walks or runs while holding the device. The movement of the one or more magnets may create an electromotive force (e.g., a voltage) across the printed coils, and this force may be used to generate electric power.

Abstract: Systems, methods, and computer readable media for sharing awareness information are provided. A non-aware electronic device can require awareness information including, for example, information about its environment or information about its status within its environment, in order to perform a particular device operation. When the non-aware device lacks an awareness component for detecting the required type of awareness information, the non-aware device can establish a communications path with an aware device that includes such an appropriate awareness component. The aware device can share the required type of awareness information as captured by its awareness component with the non-aware device. The distance between the non-aware device and the aware device can be less than a threshold distance to ensure that the shared awareness information is relevant to the non-aware device.

Abstract: This is directed to providing offline purchasing of media items using an electronic device. One or more media items that are not part of a user's media library can be stored on an electronic device. When a user later wishes to play back one of the media items, but the device cannot connect to a communications network to provide payment information for purchasing the media items, the electronic device can use pre-paid credits that were purchased and stored by the device when a communications network was available to complete the purchase. By using pre-paid credits, the media store can be assured that the user has sufficient funds for the media item purchase.

Abstract: Systems and methods are provided for defining a route from a starting point to a destination. The route can include several steps, each including an instruction directing a user to move in a particular manner, and a reference around or near which to follow the instruction. To assist the user in following the directions, a step can include one or more points of interest serving as references. In particular, points of interest having high visibility (e.g., relative to street signs) can be selected to serve as references for the directions. The device can select which points of interest to use based on any suitable criteria, including for example based on the distance of a point of interest from a location where a step requires an instruction, as well as based on visibility attributes of the points of interest.

Abstract: Systems and methods for selectively illuminating a secondary display are provided. An electronic device can include a primary display (e.g., a liquid crystal display (LCD) screen) and a printed segmented electroluminescence (secondary) display. The primary display can be used to convey visual content to a user, and the secondary display can be used to guide a user providing inputs to the device. For example, the secondary display can be selectively illuminated to provide one or more indicators that represent where or how a user can provide inputs to the device.

Abstract: Systems, methods and machine-readable media are disclosed for providing segmented graphical representations of elements, such as songs, videos, pictures, graphics, or address book contacts. In some embodiments, an electronic device may identify remote and/or local elements based on a seed element and may display a segmented graphical representation of the seed element (e.g., a tiled album cover). At least one of the segments may be associated with one or more of the identified elements. In response to receiving a user selection of a segment, the electronic device may perform any of a number of suitable actions based on the associated elements. For example, for remotely stored media elements, the electronic device can retrieve and play a preview of the media elements from a server.

Abstract: Systems, methods, and machine-readable media are disclosed for providing graphical representations of music of varying levels of detail. An electronic device can determine the attributes of a first type (e.g., genre) associated with the music. The electronic device can display a graphical representation of the music using the attributes. The graphical representation can be based on a spiral, helix, map, or any other geometric shape or curve. A user can zoom into a portion of the graphical representation to select the music of a particular genre in which to view more detailed information. In response, the electronic device can determine the attributes of a second, more detailed type (e.g., artist) associated with the selected music and can revise the graphical representation to use the attributes of the second type. The revised graphical representation can include album cover art associated with the selected music.

Abstract: Systems, methods, and machine-readable media are disclosed for providing an audio preview of songs and other audio elements. In some embodiments, the electronic device can provide a user-controllable pointer scrollable through various categories, such as different genres or artists. Responsive to each movement of the pointer, the electronic device can select a song from the pointed-to category and can play a portion of the selected song. In other embodiments, music groups can be defined, where each music group includes songs that go well together. The electronic device can play, in succession, a portion of one song from each of the music groups. Responsive to a user selection of a playing portion, the electronic device can create a playlist based on the music group of the selected playing portion.

Abstract: This is generally directed to identifying unauthorized users of an electronic device. In some embodiments, an unauthorized user of the electronic device can be detected by identifying particular activities that may indicate suspicious behavior. In some embodiments, an unauthorized user can be detected by comparing the identity of the current user to the identity of the owner of the electronic device. When an unauthorized user is detected, various safety measures can be taken. For example, information related to the identity of the unauthorized user, the unauthorized user's operation of the electronic device, or the current location of the electronic device can be gathered. As another example, functions of the electronic device can be restricted. In some embodiments, the owner of the electronic device can be notified of the unauthorized user by sending an alert notification through any suitable medium, such as, for example, a voice mail, e-mail, or text message.

Abstract: This is directed to an electronic device having an integrated sensor for detecting a user's cardiac activity and cardiac electrical signals. The electronic device can include a heart sensor having several leads for detecting a user's cardiac signals. The leads can be coupled to interior surfaces of the electronic device housing to hide the sensor from view, such that electrical signals generated by the user can be transmitted from the user's skin through the electronic device housing to the leads. In some embodiments, the leads can be coupled to pads placed on the exterior of the housing. The pads and housing can be finished to ensure that the pads are not visibly or haptically distinguishable on the device, thus improving the aesthetic qualities of the device. Using the detected signals, the electronic device can identify or authenticate the user and perform an operation based on the identity of the user.
