Abstract: Described herein are systems and methods for context aware content distribution. Content such as e-books, presentations, audio, video, applications, and so forth may be distributed to user devices after establishing a trust relationship. An invitation to provide content may be sent to a user device based on the context of the user device, such as proximity to pre-determined devices, location, and so forth. Upon acceptance of the invitation to opt-in to receiving content, a trust relationship may be established which provides for the transfer of content to the user device.

Abstract: Detection and prevention of unauthorized exchange of information between users of user devices is disclosed. Monitoring data associated with respective information received by the user devices from respective users may be received. Position information indicating proximity or relative positions of the devices may also be received. The monitoring data and/or the position information may be analyzed to determining whether unauthorized information exchange between users may be occurring. One or more metrics indicating a likelihood that unauthorized information exchange is occurring may be generated based on the analysis of the monitoring data and/or the position information. A generated metric may be compared to an associated threshold and preventive measures for deterring unauthorized information exchange may be identified based on a result of the comparison.

Abstract: One or more words at a specified location in an electronic document can be identified. The identified one or more words can be analyzed to determine one or more semantic meanings associated with the words. An audio clip (i.e., audio file, audio element) associated with or corresponding to (the semantic meaning(s) of) the one or more words can be searched for in an audio database. The search for the audio clip associated with the one or more words can utilize an index that specifies the associations between words and audio clips. In some embodiments, the audio clip can be played when an estimated location of where the user is reading is at or near the specified location of the one or more words. In some embodiments, the audio clip can be played when it is calculated that the user is reading the one or more words at the specified location.

Abstract: This disclosure describes, in part, techniques for managing access to a fleet account of mobile electronic devices. For instance, an administrator of a business and educational institution may place an order with an offering service to purchase a large number of eBook reader devices. The offering service identifies that the business and educational institution is ordering a fleet of devices. Furthermore, each of the devices ordered are associated or registered to a managed or fleet account controlled by the administrator of the business and educational institution. The techniques described herein prevent an individual user of a fleet device from de-registering the device from the managed account, and also allow an account administrator to alter preferred settings of the managed account. Further, techniques are described for allowing a user of a device to opt-in or associate their device with the account.

Abstract: In a user interface for editing electronic documents, the display of a progress meter may be delayed for long running tasks (such as the loading of an electronic document into a web browser). The user interface may include a control surface and a browser window for displaying electronic documents. A request to load an electronic document may be received in the browser window. The electronic document may then begin loading for display in the browser window. During the initial loading of the electronic document, a loading indicator may be displayed in the browser window. After a predetermined delay and while the document is still being loaded, the loading indicator may be replaced with a progress meter indicating a current loading percentage of the electronic document. The progress meter may be periodically updated during the remainder of the loading process until the entire electronic document has finished loading into the browser window.

Abstract: An electron beam image of a microcircuit pattern is projected from an irradiated photocathode window to a resist-coated silicon wafer through two successive lens systems having field-containing regions which communicate through a small aperture in a common pole structure that otherwise shields these regions from each other. The lens region in which the photocathode is located contains electrostatic and magnetic fields for accelerating the electrons and focusing the beam toward a crossover point in the aperture. The region in which the wafer is positioned contains only a magnetic field to correct aberrations of the beam image. The arrangement permits reduction of the image size. Beam registration detectors and deflecting devices are located near the aperture in the common pole structure. Because it is isolated from objects located outside of its own lens region, the electrostatic field is not perturbed by these detecting and deflecting devices or by variations in flatness of the wafer surface.
