Title: Security label and method for safeguarding objects
Inventor: DUSCHEK DETLEF
IPC: G06K19/04
Filed: 2004-01-28
Abstract: The invention relates to a security label (7') for safeguarding an object (1) from theft, comprising an electronically detectable first security element (3) and a covering layer (4) that completely covers this security element. The covering layer (4) is completely covered by a label (6) made of tearable material that, on its side facing the covering layer (4), is provided with an adhesive having an at least somewhat lower adhesive force than that of the adhesive applied to the covering layer (4). A second security element (5) is placed between the covering layer (4) and the label (6) and this security element, on its side facing the covering layer (4), is provided with an adhesive and at least partially covers the covering layer (4). The adhesive force of this adhesive is somewhat greater than that of the adhesive applied to the label (6). The covering layer (4) and the second security element (5) are completely covered by the label (6). The design of the security label (7') renders a removal of the security elements (3, 5) from the safeguarded object (1) impossible or extremely difficult.

Title: System and method for transmitting media based files
Inventor: NEWBERRY THOMAS PATRICK
IPC: H04N7/12
Filed: 2004-03-29
Abstract: A method and apparatus is disclosed for transmitting a requested media file through a network (170). A master controller (120) of a server (115) partitions the media object. The master controller (120) of the server then assigns a segment of said partitioned media object to a file partition handler (130) for transmission over the network (170) to a client (140) that requested the media object. The file partition handler (130) transmits the segment over a user datagram protocol (UDP) port through the network to a client. The master controller (120) then assigns a second segment of said partitioned media object to the file partition handler (130) when the original segment is transmitted successfully to the client (140). The segmentation of the media object is determined in response to the availability of file partition handlers (130, 160) and the conditions specified by the client (140).
