Title: Video distribution system for viewers to view video programs without paying subscription fee and being annoyed by commercial messages during video programs
Inventor: HARA KAZUHIRO
IPC: H04N7/173
Filed: 2004-10-05
Abstract: A broadcasting station server distributes a video program and calculates a viewing time of each viewer who is viewing the video program.      When the video program is finished, the broadcasting station server sends the user ID of the viewer who has viewed the video program and the viewing time thereof as viewing information through the Internet to a data center.      The data center selects the user ID of a viewer whose viewing time of the video program is longer than a predetermined time from the received viewing information, and distributes advertisement information corresponding to the video program, together with a reception acknowledgment added thereto, to a mail address corresponding to the selected user ID. If the reception acknowledgment is not returned from the recipient of the advertisement information, the data center keeps on sending the advertisement information at predetermined time intervals until the reception acknowledgment is returned.

Title: System and method for real-time media searching and alerting
Inventor: BOICEY TREVOR NELSON
IPC: G06F17/30
Filed: 2005-02-24
Abstract: A method and system for continually storing and cataloguing streams of broadcast content, allowing real-time searching and real-time results display of all catalogued video. A bank of video recording devices store and index all video content on any number of broadcast sources. This video is stored along with the associated program information such as program name, description, airdate and channel. A parallel process obtains the text of the program, either from the closed captioning data stream, or by using a speech-to-text system. Once the text is decoded, stored, and indexed, users can then perform searches against the text, and view matching video immediately along with its associated text and broadcast information. Users can retrieve program information by other methods, such as by airdate, originating station, program name and program description. An alerting mechanism scans all content in real-time and can be configured to notify users by various means upon the occurrence of a specified search criteria in the video stream.  The system is preferably designed to be used on publicly available broadcast video content, but can also be used to catalog private video, such as conference speeches or audio-only content such as radio broadcasts.

Thus, the compounds of the instant invention may be particularly useful in mammals as hypoglycemic agents for the treatment and prevention of conditions in which hyperglycemia and/or insulin resistance are implicated, such as type-2 diabetes. The compounds of the invention may also be used to treat other glucocorticoid associated disorders, such as Syndrome-X, dyslipidemia, hypertension and central obesity. The invention furthermore relates to the use of the compounds according to the invention for the preparation of medicaments, in particular of medicaments useful for the treatment and prevention of glucocorticoid associated disorders, by improving insulin sensitivity, reducing plasma glucose levels, reducing lipolysis and free fatty acid production, and by decreasing visceral adipose tissue formation.

Title: 802.11 using a compressed reassociation exchange to facilitate fast handoff
Inventor: CAM WINGET NANCY
IPC: H04L12/28
Filed: 2004-04-16
Abstract: A method and system for handling roaming mobile nodes in a wireless network.  The system uses a Subnet Context Manager to store current Network session keys, security policy and duration of the session (e.g. session timeout) for mobile nodes, which is established when the mobile node is initially authenticated. Pairwise transit keys are derived from the network session key.  The Subnet Context Manager handles subsequent reassociation requests. When a mobile node roams to a new access point, the access point obtains the network session key from the Subnet Context Manager and validates the mobile node by computing a new pairwise transient key from the network session key.
