A method and system for selecting a network to establish a connection to from a set of available network includes a network database providing historical information about each of the networks and sends the database information to end user terminals. The end user terminals monitor real-time performance information about each of the available networks and can send this information to the network database. The end user terminals also include network connection policy information which can be used to make the selection decision. The end user terminal determines a network quality score for each available network as a function of the historical information from the network database, the real-time performance information about each available network and the network connection policy information. The end user terminal can select the available network as a function of the network quality score, for example, selecting the available network with the highest network quality score.

The disclosed technology applies the principle of anonymous reciprocity to facilitate remote backups. A local computer stores other computer's backup files, while storing backup copies of local files on other computers connected through a network. Each computer may securely maintain and manage storage for other computers' files. Application may be constrained to a local area network, or work on the Internet. The disclosed technology works in a peer-to-peer environment; no central server is required. The same disclosed technology may also apply to file sharing.

A method and apparatus used in a storage network facilitates the protection of data in, and replacement of, storage devices about to fail before the failure happens. In a network that includes a set of storage devices organized as a non-redundant (for example RAID 0) array, a storage device about to fail in the non-redundant array can be replaced by another storage device, typically from a pool of spares. The method includes detecting a condition of a first particular storage device in the non-redundant array. Conditions which are detected according to various embodiments indicate that the first particular storage device is suffering events indicating that it is likely to fail, or otherwise suffering from reduced performance. The conditions are detected for example, by the receipt of a signal from the storage device itself, or by the monitoring of statistics concerning the performance of the storage device. The method further provides for selecting a particular spare storage device, which can be used in place of the first particular storage device. In response to detecting the condition, data stored in the first particular storage device is migrated to the second particular storage device, and the second particular storage takes the place of the first particular storage device in the non-redundant array. The first particular storage device can then be gracefully removed from the network without loss of service to the clients computers.

A knee prosthesis, methods of implanting the prosthesis, method of treating arthritis of the knee, and a kit therefore are provided. The prosthesis answers many of the limitations of current knee prosthetic devices by providing a two-component (or alternatively, an optional three-component) device, as either a single structure, or as separate pieces. One of the components is constructed of low friction material, while the second is composed of a weight-dissipating cushioning material; the optional third component is constructed of low friction material. The prosthesis is initially attached to surrounding soft tissue in the knee by biodegradable sutures; it is held permanently in place by fibrous ingrowth into a porous collagen rim in the cushioning component. Major improvements provided by the present invention over currently available prostheses include minimal incisions, minimal or no bone cuts, minimal overall dissection (these improvements lead to shorter hospital stays and rapid rehabilitation and fewer potential for side effects), less prosthetic wear, greater longevity, fewer activity restrictions, able to be used on young, large, active patients, ease of revision, ease of conversion into a total knee arthroplasty if needed.

By forming MOSFETs on a substrate having pre-existing ridges of semiconductor material (i.e., a “corrugated substrate”), the resolution limitations associated with conventional semiconductor manufacturing processes can be overcome, and high-performance, low-power transistors can be reliably and repeatably produced. Forming a corrugated substrate prior to actual device formation allows the ridges on the corrugated substrate to be created using high precision techniques that are not ordinarily suitable for device production. MOSFETs that subsequently incorporate the high-precision ridges into their channel regions will typically exhibit much more precise and less variable performance than similar MOSFETs formed using optical lithography-based techniques that cannot provide the same degree of patterning accuracy. Additional performance enhancement techniques such as pulse-shaped doping, “wrapped” gates, epitaxially grown conductive regions, epitaxially grown high mobility semiconductor materials (e.g. silicon-germanium, germanium, gallium arsenide, etc.), high-permittivity ridge isolation material, and narrowed base regions can be used in conjunction with the segmented channel regions to further enhance device performance.

A multi step epitaxial process can be used to extend the ridges with different dopant types, high mobility semiconductor, and or advanced multi-layer strutures. For CMOS integrated circuits a capping layer is formed over the a first region. Epitaxial layers are formed in a second region. Then the capping layer is removed from the first region and a capping layer is formed over the second region. Epitaxial layers can than be formed in the first region.

A computer filing system includes a data access and allocation mechanism including a directory and a plurality of indexed data files or hash tables. The directory is preferably a radix tree including directory entries which contain pointers to respective ones of the hash tables. Using a plurality of hash tables avoids the whole database ever having to be re-hashed all at once. If a hash table exceeds a preset maximum size as data is added, it is replaced by two hash tables and the directory is updated to include two separate directory entries each containing a pointer to one of the new hash tables. The directory is locally extensible such that new levels are added to the directory only where necessary to distinguish between the hash tables. Local extensibility prevents unnecessary expansion of the size of the directory while also allowing the size of the hash tables to be controlled. This allows optimisation of the data access mechanism such that an optimal combination of directory-look-up and hashing processes is used. Additionally, if the number of keys mapped to an indexed data file is less than a threshold number (corresponding to the number of entries which can be held in a reasonable index), the index for the data file is built with a one-to-one relationship between keys and index entries such that each index entry identifies a data block holding data for only one key. This avoids the overhead of the collision detection of hashing when it ceases to be useful.

Cached information that includes multiple network addresses is delivered in a manner that changes the order of the network addresses each time the cached information is delivered to a client, thereby achieving load balancing in a manner that reduces network traffic and improves system performance. In the preferred embodiments, the user defines a minimum time to live (TTL) and one or more order change criteria. When a query is made to a DNS, the DNS returns an answer that includes a time to live (TTL). This answer may be stored in a cache, and may include multiple network addresses. If the TTL for the answer received from a DNS is less that the minimum TTL, the TTL for the answer is set to the minimum TTL before storing the answer in the cache. When a query may be satisfied by a cached answer that includes multiple network addresses, a cache mechanism delivers the multiple cached network addresses in an order determined by the one or more order change criteria if the TTL for the cached results is a positive number. In this manner load balancing can be achieved while still benefitting from the performance enhancements of caching DNS query results.

The method allows the discharge power limits of the battery to be temporarily expanded under vehicle launch conditions where the power demands are high, thereby making additional stored energy available for use under such conditions by improving battery utilization and providing more consistent vehicle launch characteristics than would otherwise be available.
