Abstract: A system is provided that during a presentation of digital media content on a media presentation device automatically determines that a person within a predetermined area does not satisfy a threshold age. Based on the determination, the system applies one or more content rules to the presentation of the digital media content on the media presentation device. The content rules cause an alteration of the presentation of the digital media content. The system can also scan the digital media content of a content data store and estimate an age threshold value of the files of the digital media content. Based on the estimated age threshold value of the files, the system can determine that the device is used by a person who does not satisfy a threshold age and applies one or more content rules to a presentation of the digital media content.

Abstract: Features are disclosed for managing presentation of content to improve the content consumption experience as a user moves around or when there are multiple users. Based on user positions within a content consumption location and optionally on the layout of the location, presentation of content can be adjusted. The volume of audio content may be raised or lowered based on a user's position. Audio or visual content can be paused or stopped if a user leaves the location or the user's view is obstructed. When multiple users are consuming a content item, one or more users may have priority and any adjustment may be made to first improve the experience of the priority user. In some cases, no user has priority, and adjustments may be made to improve the experience of many or all users.

Abstract: Features are disclosed for searching within audio content. Users may submit search terms in text format. An index of text that is audibly presented in the audio content may be searched to identify an instance of a search term. A play position corresponding to the instance may be obtained, and a user may be provided with access to a portion of the audio content based on the play position. The particular play position that is chosen may be based on additional factors, such as popularity of the portion, prior search history and interactions, etc.

Abstract: A computing device may provide an interface that enables a user to synchronously present an item of primary content and a corresponding braille translation. The item of primary content may be an audio book, an e-book, or other form of media. The item of primary content may include supplemental information which may correspond, for example, to character descriptions, place descriptions, image descriptions, endnotes, footnotes, glossaries, appendices, commentary from an author, editor, or other party, or to additional supplemental information, and which may also have a corresponding braille translation. During presentation of the item of primary content, a user may indicate that an item of supplemental information associated with a current presentation position of the item of primary content should be presented. In some embodiments, this indication may be in response to an indication to the user that supplemental information is available.

Abstract: An in-vehicle gaming system may be played by a driver alone, or simultaneously or individually by a driver and/or one or more other users. The in-vehicle gaming system may be activated or controlled by, for example, touch, voice, or gesture. Gameplay is dynamically adjusted based at least in part on environmental factors such that the driver is not distracted from driving the vehicle. Game content is generated based at least in part on environmental factors and user data.

Abstract: A device for creating and analyzing larger symbolic representations without the limitations imposed by available resources of previous devices is disclosed. More specifically, a debugger for debugging a symbolic representation of a program is disclosed. The debugger comprising means for inputting a set of characteristics, means for linking the set of characteristics to the symbolic representation, means for identifying a first portion of the symbolic representation mutually exclusive from the set of characteristics, and means for analyzing a second portion of the symbolic representation for the set of characteristics wherein the second portion being mutually exclusive from the first portion. A method of debugging programs using the debugger, in addition to the resultant debugged program, is also disclosed.

Abstract: A device for restricting access to certain programs. The RCU comprises an entry pad, a controller, a read-only-memory ("ROM"), and an transmission system.
