Abstract: An infusion set auxiliary device and an infusion set system for vascular intervention are provided. A fixing seat is convex on a bottom plate and has a top surface, a bottom surface and a side surface which is opposite to the bottom plate. The fixing seat includes a plurality of fixing holes arranged along a first direction, and each fixing hole is used for holding a drip pot of one infusion set. The fixing hole penetrates through the side surface, the top surface and the bottom surface to form a first opening, a second opening and a third opening respectively, the sizes of the first opening, the second opening and the third opening satisfy corresponding relationships with the outside diameter of the infusion tube and the outside diameter of the drip pot. The application can arrange multiple infusion sets neatly to facilitate differentiation.

Abstract: The present invention provides a method and a device for classifying data frames. The method is typically carried out by a communication device in a wireless network with quality of service capability. It comprises the step of comparing data in a frame to data in a plurality of classifier entries, wherein the order of comparison of the classifier entries with a frame is a function of a quality of service priority level, and the step of classifying a frame for which a match is found as a function of a parameter associated with the matching classifier entry.

Abstract: The invention is related with the problem of utilizing data compression in a network of distributed stations. Often header compression is used to improve the bandwidth usage in networks, in particular wireless networks. Header compression could be implemented in access points or routers, but both implementations have serious problems, e.g. due to limited CPU power, lack of scalability, or handover latency. To resolve the problems the invention proposes to use a dedicated data compression server in the network and a new protocol to transparently deploy data compression in the network.

Abstract: A method for automatic gain control used in a receiver of a multi-carrier telecommunication system, the method comprising: receiving an input signal digitalized by an A/D converter; determining distribution of the input signal; and controlling gain of a variable gain amplifier as a function of the determined distribution.

Abstract: The present invention provides a communication system for performing the seamless handover of a mobile station between at least a first wireless access point and a second wireless access point within wireless LAN. The mobile station is in the coverage of at least the first wireless access point for receiving and/or sending the data from and/or to the first wireless access point. The system comprises a first server for storing data from a data source; a switch for exchanging the data between the first server and the first and second wireless access points; and a second server coupled to the switch, for receiving the data from the first server via a switch when the mobile station roams from one access point to another one, and transferring the stored data to the mobile station through the switch after the roaming.

Abstract: A method and apparatus for digitally encoding video image data, which is particularly suited for encoding Internet Web pages, eliminates the need for performing time consuming, computationally intensive motion vector searches by taking advantage of prior knowledge regarding the Web page movement. In a first preferred embodiment, a digital video encoder, such as an MPEG encoder, employs Web page scrolling coordinates obtained from a browser application to determine, through calculation instead of searching, motion estimation for all the macroblocks of the present image frame relative to the previous frame. In a second preferred embodiment, the encoder receives information from the browser application that indicates that certain portions of an image, such as a Web page animation window, are continuously changing, and thus should be encoded as an intra frame.
