Title: Filter for a tray, sterile tray arrangement and method of manufacturing same
Inventor: SUTER HEINZ
IPC: B01D29/01
Filed: 1998-03-06
Granted: 2009-11-24
Abstract: The invention relates to a filter (1) made of a flexible flat material (2), comprising at least one seal (3) which is firmly fixed to the flat material (2) and extend s along a closed line. Said seal (3) runs along an edge area of the flat filter material (2). To produce the filter (1) provided for in the invention, a linearly closed seal (3) is deposited by means of a foaming device on the flat material (2) which is held by a device. After application the seal is polymerised and so becomes joined to the flat material (2). To use t he material in medical trays, the flat filter material (2) must be such that no micro- organisms are able to penetrate it. To arrange such a filter (1) on a partial tray surface having through openings in such a way as to provide a seal which ensures sterility, it is sufficient to configure a closed sealing line which extends around the through openings, and to fix th e seal (3) of the filter (1) along the line tray parts to be connected with cooperating compression surfaces. Thanks to the elasticity of the seal (3) a sufficiently good joint is obtained even with low compression pressure and if the compression surfaces are not absolutely even. A further advantage of the joint between the seal (3) and the flat filter material (2) is that the filter (1) canalso be arranged on a lower side if the seal (3) is presse d into a corresponding groove, without it becoming detached from said lower side due to gravity.

IPC: H04L12/28
Filed: 2001-01-12
Granted: 2004-09-21
Abstract: The defined boundaries in a network are pushed down to the base station level. Doing so necessitates authentication each time a wireless terminal switches communication, or "handoffs" from one base station to another. To achieve such authentication in an efficient manner, security information, i.e., the derived information, is transferred from one base station directly to another. By directly it is meant without accessing any other source of the derived information, although the information may be transferred via other intervening nodes of the network that form an interconnection path for the base stations. A simplified network, i.e., a network with reduced hierarchy from a control point of view, e.g., one that only requires home location register and base station network entities along with interconnection therefore, may be employed with a minimal decrease in performance, e.g., a minimal increase in delay, during the handoff process. In one embodiment of the invention, a first base station which initially receives a service request from a wireless terminal requests authentication information from a central security node and receives in response at least, one, but typically two or more, sets of security information. When it is time for a handoff from the first base station to a second base station, the first base station transmits to the second base station at least one of the sets of security information it received from the central security node. The second base station then uses the information it received from the first base station to authenticate the wireless terminal.

Abstract: Techniques are detailed for steganographically embedding auxiliary data (1030) within electronic content (e.g., audio, video, still imagery, etc.) (1020) in manners that are computationally simple, yet highly inconspicuous (1010). The embedded data can convey copyright or other ownership information, or may be used for device control purposes (e.g., preventing unauthorized reproduction). A number of countermeasures against removal of the auxiliary data are contemplated, including keying use of the content to the presence of such data. The embedded data may be made dependent on the media encoded, e.g., by modifying the embedded data in accordance with characteristics from the media. Encryption can also advantageously be employed (1040). Playback devices may be equipped to track IDs from previously-accessed content, and enforce usage rules. Some embodiments employ multiple watermarks to advantage, e.g., a robust watermark is encoded prior to distribution and indicates the content is protected, and a second watermark is encoded by the playback device and serves to uniquely link that content to that device. Some applications benefit from scrambling of content, in a manner that leaves certain information (e.g., from a header) unscrambled and freely accessible.
