20090125397 | METHOD AND SYSTEM FOR INTEGRATING RANKINGS OF JOURNALED INTERNET CONTENT AND CONSUMER MEDIA PREFERENCES FOR USE IN MARKETING PROFILES - A method and system for integrating data-source consumer-preference data and internet-medium consumer-preference data for use in targeted advertising and ranking content. Consumer-preference data is determined based on user-interactions with a data source, such as a set-top-box. The data source is classified based on a monitoring taxonomy that specifies content categories and relationships between the categories. The consumer-preference data and the data source classification are aggregated with other preference and classification data, which is used to rank the data source classification data. Journaled internet data sources are analyzed using the monitoring taxonomy to determine internet-medium consumer-preference data. The journaled internet data sources are ranked based interest level, direction level, or authority level. A content category ranking is computed using the ranking of data source classifications and the ranking of the journaled internet data sources, which can be provided as an advertising data input or a standalone content ranking reporting tool. | 05-14-2009 |
20090125722 | CROSS-PLATFORM DIGITAL RIGHTS MANAGEMENT PROVIDING MULTI-LEVEL SECURITY INFORMATION FLOW TRACKING - A method and system for generating and controlling access to copy-protected digital media files. Digital media content is obtained and encoded in electronic file using a media codec. The encoded media content is encrypted in the electronic file and a multi-format renderer configured to render the encoded, encrypted electronic file is embedded in the electronic file. When the digital file is accessed, the multi-format renderer generates an invocation code identifying an operation-type in response to a requested operation. A transaction ID storing a user-access policy and associated with the electronic file is retrieved and compared to the invocation code. Based on a result of the comparison of the invocation code and the user-access policy, the multi-format renderer selectively allows the invocation code. | 05-14-2009 |
20100042612 | Method and system for ranking journaled internet content and preferences for use in marketing profiles - A method and system for ranking and categorizing journaled internet data sources for use in marketing and advertising. Journaled internet data sources are identified and examined. Journal data is retrieved from one or more of the data sources and a voting algorithm is applied to classify the journaled data. The journaled data is associated with one or more content categories of a monitoring taxonomy that specifies content categories and relationships between the content categories. Based on the associations, an interest level, an interaction level, a direction level, or authority level is computed and used to rank the journaled data. The rankings are stored and can be provided for use in targeted marketing and advertising. | 02-18-2010 |

20130306252 | COILING DOOR ASSEMBLY HAVING GUIDE MEMBERS WITH NARROW WALL GAP OPENING AND INTERNAL SMOKE OR WEATHER SEAL - A guide member for a coiling door or curtain assembly, including a rigid, hollow elongate member having a first wall, a second wall opposing the first wall, and a third wall which is perpendicular to the first and second walls. The first, second, and third walls are arranged to form an internal cavity of the elongate member. The internal cavity has an opening running in a direction of a length of the elongate member, along a side of the elongate member opposing the third wall. A seal is positioned in the internal cavity and attached to the second wall. The first and/or second walls have a stepped portion at the opening of the internal cavity which decreases a width of the opening by decreasing a distance between the first and second walls near the opening. | 11-21-2013 |
20140311689 | DRIVE ASSISTED ROLLER ASSEMBLY FOR ROLLING DOOR - A coupling for a door/curtain includes a plurality of coupling mechanisms affixed to ends of slats of the door/curtain. Each coupling mechanism includes a roller mounting bracket having a first roller arranged at an upper portion of the roller mounting bracket, and an extending portion, oriented at approximately 90 degrees with respect to the upper portion of the roller mounting bracket; and at least one second roller. Each second roller is rotatable around an axis perpendicular to the axis of rotation of the first roller. The first roller and the at least one second roller are arranged so as to cooperate with an outer track, inner track, roller support guide and first and second roller guides of a guide rail assembly to ensure that the door/curtain moves rollingly within the guide rail assembly even when the door/curtain is subjected to a deflecting force. | 10-23-2014 |

20150137444 | MEDIA HANDLING SYSTEMS FOR ALTERING ORIENTATION OF MEDIA - The present disclosure discloses a media transition unit for altering orientation and/or direction of travel of media that defines a first edge and a second edge, which is shorter than the first edge. The media transition unit includes a first module having a first sensor and a first conveyor belt, and a second module having a second sensor and a second conveyor belt. The first module receives the media traveling along a first direction perpendicular to the first edge. The received media is detected by the first sensor that prompts the first conveyor belt to transport the media at a first speed in a second direction perpendicular to the second edge. Upon detecting the media adjacent to the second module, the second sensor prompts the second conveyor belt to transport the media at a second speed along the second direction. The second speed exceeds the first speed. | 05-21-2015 |
