An electrosurgical generator has an output power control system that causes the impedance of tissue to rise and fall in a cyclic pattern until the tissue is desiccated. The advantage of the power control system is that thermal spread and charring are reduced. In addition, the power control system offers improved performance for electrosurgical vessel sealing and tissue welding. The output power is applied cyclically by a control system with tissue impedance feedback. The impedance of the tissue follows the cyclic pattern of the output power several times, depending on the state of the tissue, until the tissue becomes fully desiccated. High power is applied to cause the tissue to reach a high impedance, and then the power is reduced to allow the impedance to fall. Thermal energy is allowed to dissipate during the low power cycle. The control system is adaptive to tissue in the sense that output power is modulated in response to the impedance of the tissue.

A memory device and a method thereof allow programming and sensing a plurality of memory cells in parallel in order to minimize errors caused by coupling from fields of neighboring cells and to improve performance. The memory device and method have the plurality of memory cells linked by the same word line and a read / write circuit is coupled to each memory cells in a contiguous manner. Thus, a memory cell and its neighbors are programmed together and the field environment for each memory cell relative to its neighbors during programming and subsequent reading is less varying. This improves performance and reduces errors caused by coupling from fields of neighboring cells, as compared to conventional architectures and methods in which cells on even columns are programmed independently of cells in odd columns.

The present invention provides a method and apparatus for increasing the performance of world-wide-web traffic over the Internet. A distributed network of specialized nodes of two types is dispersed around the Internet. A web client's requests are directed to a node of the first type chosen to be close to the client, and the client communicates with this node using a standard protocol such as HTTP. This first node receives the request, and communicates the request to a node of the second type chosen to be close to the request's ultimate destination (e.g., a web server capable of generating a response to the request.) The first node communicates the request to the second node using a different, specialized, protocol that has been designed for improved performance and specifically to reduce traffic volume and to reduce latency. The second node receives communication from the first node using this specialized protocol, converts it back to a standard protocol such as HTTP, and forwards the request to the destination computer or server. Responses from the destination to the client take the corresponding reverse route, and also are carried over a specialized protocol between the two nodes. In addition, these nodes can employ other techniques such as web caches that avoid or improve some communication steps. Thus, specialized, proprietary, or complex protocols and techniques can be quickly deployed to enhance web performance without requiring significant changes to the clients or servers.

Stress of a silicon nitride layer may be enhanced by deposition at higher temperatures. Employing an apparatus that allows heating of a substrate to substantially greater than 400° C. (for example a heater made from ceramic rather than aluminum), the silicon nitride film as-deposited may exhibit enhanced stress allowing for improved performance of the underlying MOS transistor device. In accordance with alternative embodiments, a deposited silicon nitride film is exposed to curing with ultraviolet (UV) radiation at an elevated temperature, thereby helping remove hydrogen from the film and increasing film stress. In accordance with still other embodiments, a silicon nitride film is formed utilizing an integrated process employing a number of deposition / curing cycles to preserve integrity of the film at the sharp corner of the underlying raised feature. Adhesion between successive layers may be promoted by inclusion of a post-UV cure plasma treatment in each cycle.

Data access time in content delivery networks is improved by storing files in cache servers as file bundles. A cache server determines that multiple files are requested by the same client based on information available in the request including the IP address of the client, a URL of a webpage referring to the file, and / or a cookie stored at a client. The cache server stores multiple files requested by the same client on the hard drive as a file bundle with meta data associating the files with one another, such that they can be accessed together. A future request from the client for a file in a file bundle results in multiple files from the file bundle being loaded in the memory. If the client requests another file from the file bundle, the file is accessed directly from the memory instead of the hard drive, resulting in improved performance.

A data processing apparatus and method are provided for performing hazard detection in respect of a series of access requests issued by processing circuitry for handling by one or more slave devices. The series of access requests include one or more write access requests, each write access request specifying a write operation to be performed by an addressed slave device, and each issued write access request being a pending write access request until the write operation has been completed by the addressed slave device. Hazard detection circuitry comprises a pending write access history storage having at least one buffer and at least one counter for keeping a record of each pending write access request. Update circuitry is responsive to receipt of a write access request to be issued by the processing circuitry, to perform an update process to identify that write access request as a pending write access request in one of the buffers, and if the identity of another pending write access request is overwritten by that update process, to increment a count value in one of the counters. On completion of each write access request by the addressed slave device, the update circuitry performs a further update process to remove the record of that completed write access request from the pending write access history storage. Hazard checking circuitry is then responsive to at least a subset of the access requests to be issued by the processing circuitry, to reference the pending write access history storage in order to determine whether a hazard condition occurs. The manner in which the update circuitry uses a combination of buffers and counters to keep a record of each pending write access request provides improved performance with respect to known prior art techniques, without the hardware cost that would be associated with increasing the number of buffers.

A system and method for supplying power to a load and for controlling the power factor presented to the power line. Output voltage is controlled by a digital, outer, control loop, and inner, analog, control loop causes the input current to be substantially proportional to the input voltage at any particular point in the power line cycle. Thus, the system presents a load to the power line that appears to be purely resistive. The use of an analog multiplier is not required, nor is sampling of input voltage. Limiting of inrush current provides for brown-out protection and soft-start.

A method and system for power management including device controller-based device use evaluation and power-state control provides improved performance in a power-managed processing system. Per-device usage information is measured and evaluated during process execution and is retrieved from the device controller upon a context switch, so that upon reactivation of the process, the previous usage evaluation state can be restored. The device controller can then provide for per-process control of attached device power management states without intervention by the processor and without losing the historical evaluation state when a process is switched out. The device controller can control power-saving states of connected devices in conformity with the usage evaluation without processor intervention and across multiple process execution slices. The device controller may be a memory controller and the controlled devices memory modules or banks within modules if individual banks can be power-managed. Local thresholds provide the decision-making mechanism for each controlled device. The thresholds may be history-based, fixed or adaptive and are generally set initially by the operating system and may be updated by the memory controller adaptively or using historical collected usage evaluation counts or alternatively by the operating system via a system processor.
