A method of making a diamond heatsink includes securing a number of spaced diamonds to a sacrificial plate and then metallizing them with, for example, a thin layer of gold, silver, copper or aluminium. The plate and the diamonds are subsequently metal plated with a similar metal to the metallization until the diamonds are completely covered. The sacrificial plate is removed and the exposed surface cleaned and polished. Finally the assembly is diced to produce a number of individual heatsink assemblies.

A method of fabricating two terminal mesa semiconductor devices comprising etching a surface doped and metal coated silicon slice thereby to form a plurality of silicon frusta each capped by a metal contact pad, covering the frusta side of the slice with a metal contact continuity layer and then with a handle layer formed to lie parallel with that surface of the silicon slice which is remote from the frusta, lapping away the silicon slice to expose parts of the handle layer which extend between the frusta so that the frusta are separated so as to define discrete mesas held together by the handle layer, forming one of the two terminals on a face of the mesas remote from the contact pads, removing the handle layer to reveal the contact pads and bonding each contact pad thereby revealed to the metallized face of a diamond heat sink, one heat sink to each contact pad, which heat sink forms a part of the other of the two terminals of each mesa semiconductor device.

Compounds of Formula (I) are disclosed, wherein R1, R2, R3, R4, R5, and R18 are defined herein. The compounds encompassed by Formula (I) include compounds which are HCV NS5B inhibitors and other compounds which can be metabolized in vivo to HCV NS5B inhibitors. The compounds and their pharmaceutically acceptable salts are useful for the prophylaxis or treatment of infection by HCV and the prophylaxis, treatment, or delay in the onset of disease caused by HCV. The compounds and their salts can be employed as ingredients in pharmaceutical compositions, optionally in combination with other antivirals, immunomodulators, antibiotics or vaccines.
摘要:
A computer implemented method for extracting meaningful text from a document of unknown or unspecified format. In a particular embodiment, the method includes reading the document, thereby to extract raw encoded text, analysing the raw encoded text, thereby to identify one or more text chunks, and for a given chunk, performing compression identification analysis to determine whether compression is likely. The method can further include performing a decompression process, performing an encoding identification process thereby to identify a likely character encoding protocol, and converting the chunk using the identified likely character encoding protocol, thereby to output the chunk as readable text.

A method for adopting an orphaned I/O port of a storage controller is disclosed. The storage controller has first and second redundant field-replaceable units (FRU) for processing I/O requests and a third FRU having at least one I/O port for receiving the I/O requests from host computers coupled to it. Initially the first FRU processes the I/O requests received by the I/O port and the third FRU routes to the first FRU interrupt requests generated by the I/O port in response to receiving the I/O requests. Subsequently, the second FRU determines that the first FRU has failed and is no longer processing I/O requests received by the I/O port, and configures the third FRU to route the interrupt requests from the I/O port to the second FRU rather than the first FRU, in response to the determining that the first FRU has failed.
摘要:
A network storage appliance including one or more integrated switching devices is disclosed. The appliance includes redundant storage controllers that transfer frames of data between storage devices and host computers. The integrated switching devices include a plurality of I/O ports and a data transfer path between each of the I/O ports for providing simultaneous data transfers between multiple pairs thereof. The switches enable the appliance to simultaneously transfer frames between its I/O ports and storage device I/O ports and/or host I/O ports, thereby providing increased data transfer bandwidth over arbitrated loop configurations. Additionally, the switches are intelligent and may be programmed to achieve improved fault isolation. The appliance may also include servers that include I/O ports coupled to the switches for simultaneously transferring data with the storage controllers and/or I/O ports of devices external to the appliance.
摘要:
A storage controller that provides controlled access to storage devices by host computers is disclosed. The storage controller includes a host interface adapter that interfaces the storage controller to the hosts, a device interface adapter that interfaces the storage controller to the storage devices, and a microprocessor that processes requests by the hosts to access the storage devices. An access control table is created in response to user input in a memory accessible by the host interface adapter. When the host interface adapter receives a request, it determines from the access control table whether the requesting host has permission to access the specified storage device. If so, the host interface adapter forwards the request to the microprocessor. Otherwise, the host interface adapter transmits a response to the host denying access in one embodiment, or in another embodiment, provides an indication to the microprocessor that access should be denied.

A network storage appliance is disclosed. The storage appliance includes a port combiner that provides data communication between at least first, second, and third I/O ports; a storage controller that controls storage devices and includes the first I/O port; a server having the second I/O port; and an I/O connector for networking the third I/O port to the port combiner. A single chassis encloses the port combiner, storage controller, and server, and the I/O connector is affixed on the storage appliance. The third I/O port is external to the chassis and is not enclosed therein. In various embodiments, the port combiner comprises a FibreChannel hub comprising a series of loop resiliency circuits, or a FibreChannel, Ethernet, or Infiniband switch. In one embodiment, the port combiner, I/O ports, and server are all comprised in a single blade module for plugging into a backplane of the chassis.
