Abstract: This invention provides a method and a system to deposit a thin layer of very reactive elemental metals by plasma enhanced atomic layer deposition (PEALD). The very reactive metals, selected from the highly electropositive elements include alkaline earth metals, group III metals, and some transition and rare earth metals. The thin metal layers are formed by sequentially pulsing one of above mentioned metal containing organometallic precursors and a hydrogen plasma as a reducing agent into a reaction chamber containing a substrate surface with pulsed or continuous flow of an inert purge gas between each pulsing step. A robust high vacuum reactor chamber equipped with an anti-corrosion turbo pump and a high vacuum load lock are required for reducing contaminant gases such as O2, H2O, and CO2, and for increasing hydrogen plasma efficiency.

Abstract: The application describes various techniques for improving the accuracy and numerical stability of computer-implemented simulations which employ subgridding techniques. In particular, techniques are described in which information is transferred across a common interface between two neighboring fine-grids. Furthermore, techniques are also described in which, during the update of a grid in regions where there exists an embedded fine-grid, the field values at co-located edges at which fine-grid solution points exist on the grid, are summed and used in an approximation of the gradient term required for the FD-TD updating stencils to perform an electromagnetic simulation.

Abstract: Methods and devices for adaptively changing a parameter (such as sub-carrier bit allocation and/or gain) in a multi-carrier communication signal are described. In a method aspect, a unit that determines a need for a change sends an express change request to a second unit. The change request identifies one or more specific sub-carrier carrier to be altered and a desired value for the parameter to be changed for each identified sub-carrier. The requesting unit then monitors the communication signal it receives to determine whether the requested change has been implemented. The determination of whether the requested change has been implemented is based at least in part upon an analysis of a portion of the received communication signal that was intended to be changed. In another aspect of the invention, the change request command includes a header, a control field, at least one sub-carrier identifier, at least one desired parameter value indicator, and an error field. The header identifies the command as a change request command. The control field includes a tone count that indicates the number of tones to be altered. Each sub-carrier identifier identifies a specific sub-carrier to be altered and each desired parameter value indicator identifies a desired parameter value for its associated sub-carrier. The error field permits the unit receiving the change request to detect whether there is an error in its interpretation of the change request command.

Abstract: A network switch having switch ports for communication of data packets with respective computer network nodes according to CSMA/CD protocol that resets a retry counter for counting data packet transmission attempts within any one of the respective switch ports if backpressure is asserted by that port. A retry limit value for the retry counter is modified to ensure that the total number of retrys does not exceed a maximum total number of allowable retrys. The resetting of the retry counter within a port after assertion of backpressure affords the port a greater probability of transmitting earlier under the CSMA/CD protocol, thus more quickly relieving congestion which may occur in the network switch. The modification of the retry limit value ensures that the number of retrys for the port does not exceed industry standards.

The network includes at least one network element having a detection device operable to detect a possible physical intrusion in a data communication path connected to the network element. The method includes receiving a notification from the detection device that the detection device has identified a physical intrusion in the data communication path, generating an alert, and transmitting the alert over the packet switched network. The alert may include instructions on how to remediate the physical intrusion that can be automatically implemented by a given network-connected device or manually addressed by a network user or network administrator.
