摘要:
A method for improving the uniformity of high-frequency discharge plasma by means of frequency modulation is disclosed. In a plasma discharge chamber, there is a pair of parallel electrodes. A high-frequency power supply is adopted to feed the electrodes. The frequency range of the electromagnetic field is 13.56 MHz˜160 MHz. Discharge gas is input to form plasma. The frequency of the fed-in high-frequency electromagnetic field is under automatic tuning control, and keeps changing cyclically without stop in the course of plasma discharge. The range of the frequency change may fall into either a portion of or the entire range of 13.56 MHz˜160 MHz and makes the locations with higher plasma density on the plane in parallel with the electrodes and in the plasma discharge space changed cyclically. In a time slot longer than one frequency change cycle, the average plasma density between the parallel electrodes is uniform.

Systems and methods are provided to detect when a virtual machine moves across a switch device boundary, keep existing application sessions alive, and provide optimal forwarding for new application sessions with graceful address migration. Virtual machine movement can be detected on the new switching device by comparing the Device ID in the Source Address of the ND-NA with the Device ID of the new switching device. A temporary hardware forwarding sub-optimal path is maintained for existing application sessions. A new IP address is assigned to the moved virtual machine and an optimal forwarding path is programmed in hardware for new application sessions. The temporary sub-optimal hardware forwarding path is removed after all old application are terminated.

A white LED lighting device driven by a pulse current is provided, which consists of blue, violet or ultraviolet LED chips, blue afterglow luminescence materials A and yellow luminescence materials B. Wherein the weight ratio of the blue afterglow luminescence materials A to the yellow luminescence materials B is 10-70 wt %:30-90 wt %. The white LED lighting device drives the LED chips with a pulse current having a frequency of not less than 50 Hz. Because of using the afterglow luminescence materials, the light can be sustained when an excitation light source disappears, thereby eliminating the influence of LED light output fluctuation caused by current variation on the illumination. At the same time, the pulse current can keep the LED chips being at an intermittent work state, so as to overcome the problem of chip heating.

Systems and methods are provided to support a large number of hosts while keeping the size of the FIB CAM low. Higher scalability may be achieved by consuming less FIB CAM space as hosts are added to a network. An L3 switching module may be provided capable of supporting a large number of virtual machines and/or hosts while maintaining a small FIB CAM size on a multiple device virtual switching system with port or device level aggregation.

Systems, methods, and apparatus that select a radio access technology based on a usage history are presented herein. A recording component can record, based on a first use of a wireless communication network, information identifying a radio access technology associated with the first use. A selection component can select, in response to receiving a request for a second use of the wireless communication network, the radio access technology for the second use based on the information. A transfer component can determine whether a request for a handover is based on a wireless service coverage. Further, the transfer component can determine whether a request for a reselection is based on the wireless service coverage. Moreover, the selection component can select another radio access technology for the second use in response to the request being based on the wireless service coverage.

Some embodiments include methods of forming patterns of openings. The methods may include forming spaced features over a substrate. The features may have tops and may have sidewalls extending downwardly from the tops. A first material may be formed along the tops and sidewalls of the features. The first material may be formed by spin-casting a conformal layer of the first material across the features, or by selective deposition along the features relative to the substrate. After the first material is formed, fill material may be provided between the features while leaving regions of the first material exposed. The exposed regions of the first material may then be selectively removed relative to both the fill material and the features to create the pattern of openings.

Web page load time prediction is achieved by simulating and adjusting the load times of web objects in a webpage to determined adjustments that optimize an overall page load time (PLT) of the webpage. The webpage load time prediction includes extracting a parental dependency graph (PDG) for the webpage. The PDG encapsulates one or more dependency relationships for each web object in the webpage. The prediction further includes determining an original PLT and original timing information of a webpage. The prediction also includes simulating a page loading of the webpage based on adjusted timing information of each web object and the PDG to estimate a new PLT of the webpage. The prediction additionally includes comparing the original PLT of the webpage to the new PLT of the webpage to determine whether the adjusted timing information increased or decreased the new PLT of the webpage.
