摘要:
At least one input/output (I/O) firmware partition is provided in a partitioned environment to facilitate access to I/O resources owned by the at least one I/O firmware partition. The I/O resources of an I/0 firmware partition are shared by one or more other partitions of the environment, referred to as consumer partitions. The consumer partitions use the I/O firmware partition to access the I/O resources. Since the I/O firmware partitions are responsible for providing access to the I/O resources owned by those partitions, the consumer partitions are relieved of this task, reducing complexity and costs in the consumer partitions.

A method is provided for communication between a plurality of stations in a communication network using media access protocol, in which medium access is granted to stations obtaining a successful reservation of the medium and in which data transmission verification is performed by the protocol within the reservation. In the method a station sends a request message on the communication medium for a reservation of the medium to a recipient station in the network. The recipient station sends a reservation confirmation message back to the sending station which receives it and responds to the reservation confirmation message by sending an ordered sequence of data frames to the recipient station. After sending the ordered sequence of data frames the sending station sends an end of transmission message to the recipient station, which replies by sending back an end of transmission confirmation identifying the number of frames received in their original sequence. If the number is not correct remedial action can be taken by the sending station to resend missing data. Address conflict resolution is also provided by another aspect of the invention. The invention has embodiments which handle unicast and groupcasting transmissions.

An elastic interface apparatus and method are implemented. The elastic interface includes a plurality of storage units for storing a stream of data values, wherein each storage unit sequentially stores members of respective sets of data values. Each data value is stored for a predetermined number of periods of a local clock. Selection circuitry may be coupled to the storage units to select the respective data value from the data stream for storage in the corresponding storage unit. Data is sequentially output from each storage unit in synchrony with the local clock on a target cycle of the local clock.

Power and ground planes (203, 205) that are used in Printed Circuit Boards (PCBs) and that comprise porous, conductive materials are disclosed. Using porous power and ground plane materials in PCBs allows liquids (e.g., water and/or other solvents) to pass through the power and ground planes (202, 205), thus decreasing failures in PCBs (or PCBs used as laminate chip carriers) caused by cathodic/anodic filament growth and delamination of insulators. Porous conductive materials suitable for use in PCBs may be formed by using metal-coated organic cloths (such as polyester or liquid crystal polymers) or fabrics (such as those made from carbon/graphite or glass fibers), using metal wire mesh instead of metal sheets, using sintered metal, or making metal sheets (202, 205) porous by forming an array of holes (220) in the metal sheets. Fabrics and mesh may be woven or random. If an array of holes (220) is formed in a metal sheet, such an array may be formed with no additional processing steps than are performed using conventional PCB assembly methods.

To display contents desired by a user in one information terminal onto another information terminal having no special software for collaboration when collaboration is performed through internets. If a customer clicks on a "call button" with a browser, an agent who performs collaboration is assigned. The browser on the customer side shows both a screen starting a default and an object giving instructions to display the next page. The screen on the agent side shows the number of a document to which the customer refers, and the agent can change this number. If the customer selects the object giving instructions to display the next page, a hypertext makeup language (HTML) including that object is generated based on the document number changed by the agent, the HTML being transmitted to the customer side.
摘要:
A reference current (ICAL) and resistance is used to determine a reference voltage. A variable current is then applied to the MR read head, and is adjusted to produce a voltage equal to that of the reference voltage (V ref). Then, the known current and voltage is used to determine the resistance of the MR read head.

A method of enabling a proxy to participate in a secure communication between a client and a set of servers. The method begins by establishing a first secure session between the client and the proxy. Upon verifying the first secure session, the method continues by establishing a second secure session between the client and the proxy. In the second secure session, the client requests the proxy to act as a conduit to a first server. Thereafter, the client and the first server negotiate a first session master secret. Using the first secure session, this first session master secret is then provided by the client to the proxy to enable the proxy to participate in secure communications between the client and the first server. After receiving the first session master secret, the proxy generates cryptographic information that enables it to provide a given service (e.g., transcoding) on the client's behalf and without the first server's knowledge or participation. If data from a second server is required during the processing of a given client request to the first server, the proxy issues a request to the client to tunnel back through the proxy to the second server using the same protocol.

A user of a remote computer accesses a target computer (e.g., the user's home PC) via the Internet. To initiate the protocol, the user launches an application which, via the Internet, sends a special request to the user's home e-mail address. If the home computer is not currently connected to the Internet, the user's Internet Service Provider (ISP) dials a telephone number for the home computer. The home computer automatically answers, and the ISP sends authentication information to the computer to establish an Internet connection. With the connection established, an IP address is sent back to the user, which can then be used to invoke X-10 functions, telnet sessions, or other activities with the target computer.

A non-uniform memory access (NUMA) computer system includes at least a local processing node and a remote processing node that are each coupled to a node interconnect. The local processing node includes a local interconnect, a processor and a system memory coupled to the local inteconnect, and a node controller interposed between the local interconnect and the node interconnect. In responce to receipt of a read request from the local interconnect, the node controller speculatively transmits the read request to the remote processing node via the node interconnect. Thereafter, in response to receipt of a response to the read request from the remote processing node, the node controller handles the response in accordance with a resolution of the read request at the local processing node. For example, in one processing scenario, data contained in the response received from the remote processing node is discarded by the node controller if the read request received a Modified Intervention coherency response at the local processing node.
摘要:
A mounting interface for a spindle motor allows the optimization of the spindle dynamics. The mounting interface provides a steadfast relationship between a motor and a baseplate, wherein the mounting interface includes at least three surface points forming a single plane acting as a common boundary between the motor and the baseplate. The three surface points may be pads, and the pads may be coupled to the baseplate or to the mount flange. The three surface points provide reduced contact area between the mount flange and the baseplate, and the reduced contact area lowers the rigidity of the mount flange and the resonant frequencies. The surface area of the pads and the material of the pads is chosen to reduce acoustical noise. In addition, a damping ring may be provided for dissipating distortion energy between the motor, baseplate and/or mount flange.
