摘要： An interpenetrating polymer network (IPN) composition and a process for the manufacture of hydrogel contact lens using the invention material. The polymeric materials are formed by polymerization of: (1) an unsaturated alkyl(meth)acrylate or its derivatives such as 2-hydroxyethyl methacrylate as the principle monomer; (2) optionally vinyl containing comonomer(s) to enhance the resulting hydrogel water absorbing capability; (3) polymerizable multi-functional crosslinking agent(s); (4) an irradiation initiator and/or thermal initiator; (5) optionally other additives to impart the resulting hydrogel specific properties such as ultra-violet blocking ability and handling colors; in the presence of a soluble, hydrophilic IPN agent such as polyvinylpyrrolidone (PVP) or poly-2-ethyl-2-oxazoline (PEOX) with a specific molecular weight range. The novel hydrophilic hydrogel material in the present invention can be used to produce a spherical contact lens, a toric contact lens, a multifocal contact lens, a toric-multifocal contact lens, and other medical devices. The inventive hydrogel material shows a low degree of surface friction, a low dehydration rate, and a high degree of biodeposit resistance.

摘要： The present invention is a method and apparatus for positioning a read/write head in a hard disk drive. The method comprises providing a disk having a at least one side with a plurality of tracks, where each of the tracks has a servo field with servo bits. The servo bits are read to provide a position signal for positioning a read/write head. The method determines a difference in position between an initial and a subsequent position of the read/write head on a track, where the subsequent location occurs after the read/write head has moved one revolution from the initial position on the track. The initial and subsequent positions are offset laterally. The method generates a compensation signal based on the initial position, the subsequent position and the difference. The position signal and the compensation signal are combined to provide a compensated position signal for positioning the read/write head. Various embodiments are described.

摘要： A cache coherent distributed shared memory multi-processor computer system is provided with a memory controller which includes a recall unit. The recall unit allows selective forced write-backs of dirty cache lines to the home memory. After a request is posted in the recall unit, a recall (“flush”) command is issued which forces the owner cache to write-back the dirty cache line to be flushed. The memory controller will inform the recall unit as each recall operation is completed. The recall unit operation will be interrupted when all flush requests are completed.

摘要： Systems and methods of processing network packets are described. These systems and methods provide improved packet processing results by logically and physically separating packet header processing functions from packet data processing functions. In this way, a network processing system may perform network handling operations and data processing operations substantially in parallel. One or more embodiments feature a network adapter for exchanging with a computer network information in the form of packets each including a packet header and packet data. The network adapter includes a packet parser configured to parse an information packet into a packet header and packet data and to direct the packet header to a first memory address for protocol processing and to direct packet data to a second memory address for data processing.

摘要： Described herein is technology for, among other things virus scanning for block-level distributed application management. The technology involves storing blocks of a root image on a first storage unit and storing blocks of leaf images on respective second storage units. The leaf images include additional data blocks not previously contained in the root image and changes made by respective compute nodes to the blocks of the root image. The technology includes receiving a notification from one of the compute nodes that the root image has been scanned for viruses and providing the notification to other compute nodes.

摘要： Client-server software partitions Windows applications into multi-media and other less-observable instructions such that client may run audio/visual-related commands remotely, thereby appearing to client-user as when application were run solely by central server. Clients may access application through web-sites or remote access servers. Client requests may be atomized such that instruction set sub-sets are partitioned correspondingly. Operating system parameters on which application is run may be accessed selectably. Server may centralize client administration and provide metering of application usage.

摘要翻译： 客户端 - 服务器软件将Windows应用程序划分为多媒体和其他不太可观察的指令，以便客户端可以远程运行音频/视频相关命令，从而在应用程序仅由中央服务器运行时呈现给客户端用户。 客户端可以通过网站或远程访问服务器访问应用程序。 客户端请求可以被雾化，使得指令集子集被相应地分区。 运行应用程序的操作系统参数可以被可选地访问。 服务器可以集中客户端管理并提供应用程序使用的计量。
