A weighted round robin (WRR) engine includes components to arbitrate emission of ATM cells assigned to different flows. In one embodiment termed an inter-QoS WRR, the flows are linked to quality of service (QoS) parameters. A tag value is further assigned to each QoS parameter. Whenever the QoS is selected by the Inter-QoS WRR to have a flow emit an ATM cell, the tag value for the QoS is incremented by a weight assigned to the QoS. The QoS selected by the Inter-QoS WRR is the QoS with the lowest tag. If two or more QoSs are tied with the lowest tag, the highest numbered QoS is selected by the WRR.

A scheduling system for distributing asynchronous transfer mode (ATM) telephone signals from an ATM cell queuing device. The scheduling system includes a number of port shapers. A port shaper can support a number of flows with each flow identifying a number of ATM cells. A port shaper directs the subscriber. Each flow assigned to a port shaper identifies ATM cells which are to be distributed to a different device used by a subscriber, such as a telephone or computer. A port shaper further includes a number of time descriptors. Flows are linked to the time descriptors. The time descriptors are sequentially activated. When a time descriptor becomes active, a flow linked to the time descriptor can emit an ATM cell, and after emitting the cell the flow is relinked to subsequent time descriptors based ona weighting increment I to accommodate different device bandwidths.

A virtualization platform provides fault tolerance for a primary virtual machine by continuously transmitting checkpoint information of the primary virtual machine to a collector process, such as a backup virtual machine. When implemented on a hardware platform comprising a multi-processor that supports nested page tables, the virtualization platform leverages the nested page table support to quickly identify memory pages that have been modified between checkpoints. The backup virtual machine provides feedback information to assist the virtualization platform in identifying candidate memory pages for transmitting actual modifications to the memory pages rather than the entire memory page as part of the checkpoint information. The virtualization platform further maintains a modification history data structure to identify memory pages that can be transmitted simultaneous with the execution of the primary virtual machine rather than while the primary virtual machine has been stunned.

Methods for providing pharmaceutical compositions and objects with identification regions and identification features which are difficult to detect. Microlithography, nanolithography, and stamping methods are used. The identification features can be positive protrusions or negative indentations with respect to the surface. The identification regions can comprise bar codes and holograms. DPN printing or other lithographies such as electron beam lithography, optical lithography, or nanoimprint lithography can be used to prepare stamps, which are then used to prepare the identification features. Redundant patterns can be formed. The invention is useful for counterfeit prevention. An apparatus for stamping the identification features is also described.

A system and method for aligning prior patterning positions formed by a first SPM tip with a second SPM tip in combination with an SPM system includes identifying first location information that includes a location of the first SPM tip and a sample reference location on an SPM sample and storing the first location information in a storage area. After replacing the first SPM tip with the second SPM tip, second location information, which includes a location of the second SPM tip and the sample reference location on the SPM sample, is identified. Displacement is calculated between the location of the second SPM tip and the first SPM tip based on the first and second location information, and either the second SPM tip or a stage supporting the SPM sample is translated to align the second SPM tip with the location of the first SPM tip in accordance with the calculated displacement.

Inkwells adapted for use in direct-write nanolithography and other applications including use of wells, channels, and posts. The wells can possess a geometry which matches the geometry of tips which are dipped into the inkwells. The channels can be open or closed. Hydrophilicity and hydrophobicity can be used to control ink flow. SEM can be used to characterize the inkwells. Ink flow can be monitored with video. Hydrophobic material layers can be used to prevent cross contamination. Microsyringes can be used to fill reservoirs. Satellite reservoirs can be used to prevent bubble formation.

A method and apparatus for providing dynamic route advertisement based on IP-Sec security associations are disclosed. The method receives a notification for an establishment, a deletion or a modification of a security association for a sub-network. The method then adds or deletes a route for the sub-network based on the security association and dynamically advertises the added or deleted route to one or more peer devices. In one embodiment, the method also receives an advertisement for an added or deleted route from a peer device, identifies at least one IP-Sec client for receiving the advertisement, and establishes or deletes one or more security associations for the at least one identified IP-Sec client.

An apparatus for use in fabricating structures and depositing materials from tips to surfaces for patterning in direct-write mode, providing ability to travel macroscopic distances and yet provide for nanoscale patterning. Useful in small scale fabrication and nanolithography. The instrument can be compact and used on a laboratory bench or desktop. An apparatus comprising: at least one multi-axis assembly comprising a plurality of nanopositioning stages, at least one pen assembly, wherein the pen assembly and the multi-axis assembly are adapted for delivery of material from the pen assembly to a substrate which is positioned by the multi-axis assembly, at least one viewing assembly, at least one controller. Nanopositioning by piezoelectric methods and devices and motors is particularly useful. The apparatus can include integrated environmental chambers and housings, as well as ink reservoirs for materials to be delivered. The viewing assembly can be a microscope with a long working distance. Particularly useful for fabrication of bioarrays or microarrays. The multi-axis assembly can be a five-axis assembly. Software can facilitate efficient usage.

An apparatus, program product and method utilize a brokering service for use in controlling the incorporation of likeness data for an individual into a media presentation. The brokering service maintains a plurality of rulesets respectively associated with a plurality of individuals. Each ruleset is used to restrict or otherwise control the incorporation of likeness data associated with an associated individual into media presentations, typically through the inclusion of one or more rules configured to define conditions under which the likeness data for the associated individual may or may not be incorporated into a media presentation. The brokering service is capable of responding to requests for selected rulesets for different individuals by communicating the rulesets to various requesting entities.
