20120320916 | TRANSPORT PROTOCOL FOR ANTICIPATORY CONTENT - Methods, apparatuses, and systems for improving utilization of a communications system (e.g., a satellite communications system) are provided, using delayed reliability techniques as part of a multicast transport protocol. Embodiments may operate in a client-server context, in which the server-side of the communication link multicasts data to requesting users and to users where the data is being speculatively prepositioned. Requesting users may implement reliability checks to verify receipt of complete data in response to the request while user systems where data is being speculatively prepositioned may receive multicast reliability information in response to reliability requests from other users, but may not request replacement of missing or corrupted data themselves until a request is made for the data by that system. | 12-20-2012 |
20130124621 | METHODS AND SYSTEMS FOR IMPLEMENTING A CACHE MODEL IN A PREFETCHING SYSTEM - The present invention relates to systems and methods of enhancing prefetch operations. One potential method comprises fetching an object from a page on a web server. The method may further include storing, at a proxy server, caching instructions for the fetched object. The proxy server may be connected with the client and the object is cached at the client. Furthermore, the method may include identifying a prefetchable reference to the fetched object in a subsequent web page and using the caching instructions stored on the proxy server to determine if a fresh copy of the object will be requested by the client. Further, the method may include, based on the determination that the object will be requested, sending a prefetch request for the object using an If-Modified-Since directive, and transmitting a response to the If-Modified-Since directive prefetch request to a proxy client. The proxy client may then either serve the response to the client or a copy of the object stored at the proxy client, depending on the request for the object from the client. | 05-16-2013 |
20130279505 | INTERNET PROTOCOL BROADCASTING - Methods, apparatuses, and systems are provided for improving utilization of a communications system through various atom-based techniques for enhancing the viewing experience for Internet protocol content. Some embodiments exploit atom-based processing to determine which content atoms to broadcast (e.g., multicast) over which channels to which subscribers. Other embodiments make atom-based filtering, caching, and/or other determinations at the user terminal. For example, low-level (e.g., physical layer) filtering may be used to limit the amount of user-layer processing needed, and to facilitate delivery of content to those users most likely to desire that content. Still other embodiments allow users to create customized channels of cached content for viewing as a shared channel. Embodiments include techniques for addressing synchronization of channel content and viewing, and social networking, for subscribers to the shared channel. The shared channels may be further used to facilitate social networking among subscribers. | 10-24-2013 |
20130326217 | SELF-KEYED PROTECTION OF ANTICIPATORY CONTENT - Systems and methods are provided to facilitate anticipatory pushing of content to clients of a communications network in such a way that the content is unusable by the anticipatory clients until explicitly requested. Embodiments apply one or more self-keying techniques to a content dataset to generate an anticipatory dataset, such that the anticipatory dataset cannot be used to reconstruct the content dataset without a keying dataset that also can only be generated using the content dataset. The anticipatory dataset is pre-pushed to a client in anticipation of a future request for the content. If and when the client subsequently issues a request for the content dataset, the server intercepts the new copy of the content dataset received in response to the request, uses the content dataset to generate the keying dataset, and communicates the keying dataset to the client for local reconstruction of the content dataset by the client. | 12-05-2013 |
20140029612 | CORRELATIVE ANTICIPATORY DELTACASTING - Methods, apparatuses, and systems for improving utilization of a communications system (e.g., a satellite communications system) are provided through techniques referred to herein as “deltacasting.” Some embodiments use a server-side optimizer to intercept and create fingerprints of byte-level content data traversing links of the communications system. The content fingerprints are used to transparently identify communications patterns (e.g., repetitious downloads of the same content, correlations between users, etc.), which may then be used in exploiting multicasting and/or other opportunities for increased utilization of the communication links. | 01-30-2014 |
20140040353 | RETURN-LINK OPTIMIZATION FOR FILE-SHARING TRAFFIC - Methods, apparatuses, and systems for return-link optimization are provided. Embodiments identify upload-after-download content (e.g., file sharing content) upon download, and generate one or more identifiers characterizing the content (e.g., a digest). The identifiers are stored in a client-side server dictionary model reflecting a presumption that the content is stored in a server-side dictionary. When content is later uploaded, the server dictionary model is used to identify when the upload content matches previously downloaded content. When a match is detected, the stored identifiers are used to generate a highly compressed version of the upload content, which is then uploaded to the server instead of uploading the full content data. In some embodiments, similar techniques are used to optimize return link bandwidth usage for upload-after-upload transactions. | 02-06-2014 |
20140082478 | METHODS AND SYSTEMS FOR JAVASCRIPT PARSING - The present invention relates to systems, apparatus, and methods of parsing a script within an HTML page. The method includes receiving a script object, where the script object includes text. The method further includes parsing the text of the script object for tokens and comparing the parsed tokens with a valid tokens list to determine locations within the text of the script object that include potential universal resource locators (URLs). The method includes parsing before and after the determined locations until complete URLs are constructed, and forwarding the complete URLs to a detector. The detector then determines whether the complete URLs are valid. The method then sends object retrieval requests to websites associated with the valid complete URLs. | 03-20-2014 |
20140274397 | PLATFORM FOR FINGER CONTROLS - A hand-mounted controller is provided that allows a user to manipulate individual sensors associated with one or more, and typically each, of a wearer's fingers and thumb while monitoring movement of the controller in three dimensional space. The controller includes a palm grip that may be affixed to the hand via straps. Attached to the palm grip is one or more finger actuated controls and one or more thumb actuated controls. A position sensor detects the position and orientation of the hand. The palm grip is contoured to distribute pressure across the carpals and the four finger metacarpals, while providing clearance so as not to interfere with the finger metacarpophalangeal joints and/or the thumb carpometacarpal joint. | 09-18-2014 |
20150026241 | DELTACASTING FOR OVERLAPPING REQUESTS - Methods, apparatuses, and systems are provided for improving utilization of a communications system (e.g., a satellite communications system) when handling overlapping content requests. Embodiments use various techniques (e.g., dictionary coding techniques) to create fingerprints of content traversing the links of the communications system. These fingerprints are used to identify and exploit opportunities for using multicasting to share forward-link capacity by collapsing multiple overlapping requests for the same content via multiple content session streams into fewer session streams, including one or more shared session streams. | 01-22-2015 |
20150032848 | CORRELATIVE ANTICIPATORY DELTACASTING - Methods, apparatuses, and systems for improving utilization of a communications system (e.g., a satellite communications system) are provided through techniques referred to herein as “deltacasting.” Some embodiments use a server-side optimizer to intercept and create fingerprints of byte-level content data traversing links of the communications system. The content fingerprints are used to transparently identify communications patterns (e.g., repetitious downloads of the same content, correlations between users, etc.), which may then be used in exploiting multicasting and/or other opportunities for increased utilization of the communication links. | 01-29-2015 |
