Abstract: Embodiments described herein are directed to tracking objects using a cognitive heterogeneous ad hoc mesh network. A first participant receives a notification signal from a second participant. The first participant determines first positioning information from the notification signal and second positioning information from characteristics of the received signal. If the difference between the first and second positioning information is below a first threshold, then the second participant is within line-of-sight of the first participant. If the difference is above the first threshold and below a second threshold, then the second participant may have a malfunctioning sensor. But if the difference is above the second threshold, then the second participant is not within line-of-sight of the first participant and the received signal was reflected off another object. The positioning information can then be refined or transmitted to other participants.

Abstract: Educational book covers including a spine, a cover member, and a pull mechanism. The cover member pivotally couples to the spine. The cover member has an outer face. The pull mechanism is attached to the outer face. The pull mechanism includes a track and a knob. The track is coupled to the outer face. The track defines fixed pull positions along the length of the track. The knob is complementarily configured with the track to selectively rest within the fixed pull positions. The cover member includes unique indicia aligned with each fixed pull position to identify and differentiate the fixed pull positions for educational purposes. More force is required to pivot the cover member relative to the spine by pulling the knob when the knob is selectively translated within the track closer to the spine than when the knob is selectively translated within the track farther from the spine.

Abstract: An application for dynamic, granular access permissions can include a database interface, a user interface, a login process, an administrator, an event handler and an authorization process. The database interface can be an interface to an access control permissions database that stores roles, actions, or policies for users of the application. The login process can authenticate a user and determine a default set of access control permissions for that user when they are using the user interface. The administrator can provide access control permissions for a user by using the database interface. The event handler can dynamically modify access to functionality in the user interface based on an event. The authorization process can determine whether a request from the user interface is authorized before process the request. The authorization process can use access control permissions from the administrator and either a scope limited or a temporally limited access permission.

Abstract: Systems and methods for sharing content between devices are disclosed. To request a shared piece of media content, a playback device generates and sends a request to content server. The playback device includes information in the request that indicates the playback capabilities of the device. The content server receives the request and determines the playback capabilities of the playback device from the information in the request. The content server then determines the assets that may be used by the playback device to obtain the media content and generates a top level index file for the playback device that includes information about the determined assets. The top level index file is then sent to the playback device that may then use the top level index file to obtain the media content using the indicated assets.
