Abstract: When confidential information is displayed at a display device, a secure image may be generated so that the confidential information is visible only to an authorized user within a predetermined viewing distance. In some examples, incorrect information may be generated to mislead an unauthorized viewer outside the predetermined viewing distance.

Abstract: Methods and systems for supplying media over communication networks are described. In one embodiment, a media supplier determines whether a media object hosted on a web server will be supplied to a client by streaming or not by streaming. Preferably, if the determination is to stream, the media supplier streams the media object to the client. In some cases, the same media supplier may be capable of supplying clients with media objects hosted on any of at least two web servers.

Abstract: Methods of curing a photo-curable material, photo-curing devices, apparatuses for curing a photo-curable material, and methods of forming a photo-curing device are disclosed. A method of curing a photo-curable material may include placing a photo-curing device having a magnetic body adjacent to the photo-curable material and controlling movement of the photo-curing device with at least one magnet. A photo-curing device may include a magnetic body and at least one light source positioned at one or more locations on the magnetic body and configured to emit electromagnetic radiation. The magnetic body may be configured to be movable adjacent to a photo-curable material by at least one magnet.

Abstract: According to some examples, a lens apparatus includes a plurality of near-field spatial filters, each of the near-field spatial filters including a first near-field lens that includes a first focal length, a second near-field lens that includes a second focal length, and a first plate that includes a pin-hole, the first plate being disposed between the first near-field lens and the second near-field lens such that the pin-hole in the first plate is substantially at a point where a focus of the first near-field lens and a focus of the second near-field lens substantially coincide based at least in part on the first focal length and the second focal length.

Abstract: In an AR system, an AR display device may be configured to generate a virtual image that includes information provided by a computer device next to or overlaying a physical object that is observed by a user utilizing the AR system in real time.

Abstract: Technologies are generally described for methods and systems effective to generate modified content data. In some examples, the methods may include obtaining, by a processor, identification data associated with an identification. The processor may generate offset data using the identification data, where the offset data may include an indication of the identification. The processor may determine first position data that may be effective to define a first position of a first object and a second position of a second object in a source document that corresponds to source content data. The processor may generate second position data using the offset data and the first position data. The second position data may be effective to define a third position of the first object and a fourth position of the second object. The processor may generate the modified content data by application of the second position data to the source content data.

Abstract: In one example, a method includes generating a first digital code that represents a content of a document created by a first user; and notarizing the creation of the document by triggering a plurality of remittances from a first account associated with the first user to a second account, with each of the plurality of remittances time-stamped and a respective amount of each of the plurality of remittances indicating a corresponding portion of the first digital code.

Abstract: Technologies are generally described for handheld electronic devices. In various examples, a handheld electronic device arranged in accordance with the present technology can include a display on a first side and a user input device having a sensor on a second side opposite the first side. The sensor can be configured to detect finger locations of a user on the second side relative to the user input device and to generate a sense signal accordingly. An indication may be presented on the display at the first side based on the sense signal.

Abstract: A peer-to-peer communication system in which a peer communicating with a tracker node on a local torrent can locate and download files that are not currently available from other peers communicating on the local torrent. To enable this, the tracker node maintains collaboration information for a list of files. The collaboration information includes, for each file, a list of locations at which a full copy of the file may be located. The list of locations may include active peers, dormant peers and remote tracker nodes. The collaboration information may be obtained from each peer when it joins a local torrent. Upon joining the torrent, the peer may provide the local tracker node with a list of files that it is willing to serve.

Abstract: A method and system for streaming media objects. A streaming system includes a group of end nodes and at least one core node connected via an overlay network. The end nodes cache segments of media objects and stream the media objects to a client segment by segment. Each end node stores segment indices for locating segments cached on end nodes or a core node in the system. The core node is a dedicated proxy which fetches media objects from a remote media server and streams the media objects to a client when the media objects are unavailable from the end nodes.

In one embodiment, a media supplier determines whether a media object hosted on a web server will be supplied to a client by streaming or not by streaming. Preferably, if the determination is to stream, the media supplier streams the media object to the client. Otherwise, the media supplier preferably allows the host web server to supply the media object to the client. In some cases, the same media supplier may be capable of supplying clients with media objects hosted on any of at least two web servers.
