    摘要: A system that facilitates enhanced security with respect to an industrial automation environment comprises a legacy device that is existent within an industrial automation system and a central access authority that provides access rules to a proxy. The proxy receives an access request directed to the legacy device and determines whether the access request is permitted based at least in part upon characteristics of the access request and the access rules provided by the central access authority.

    摘要: A technique is provided for defining a self-forming sleeve between a male shaft and a female or hollow shaft. The self-forming sleeve prevents wear and fretting at the interface between the male shaft and the hollow shaft while permitting torque to be transmitted through the interface. The self-forming sleeve may be made of a curable liquid, such as an adhesive or sealing compound. The sleeve material is applied either to the hollow bore, to the male shaft, or to both immediately prior to an assembly step. Following curing or bonding of the self-forming sleeve, the sleeve will not drain, flow or otherwise be extruded from the interface between the male shaft and hollow bore, providing continued operation with a minimal degree of wear and fretting at the interface. The self-forming sleeve allows the mating male and hollow shafts to be disassembled, after extensive periods of operation, without excessive force and without significant damage to shafts and connected machinery.

    摘要: In one embodiment, the components within each respective unit of the MCC are connected powered by a connector assembly that is directly engaged to secondary power and network data conductors disposed of within the enclosure. The connector assembly, if so desired, will maintain connection even upon disengagement of the unit from the main power supply. This service position can be employed to provide a safe environment for diagnostic testing and repair of the unit. In another embodiment, the secondary power and network data conductors may by carried over an open rail system. This embodiment provides a convenient means of quickly and easily engaging the secondary power and network data conductors to the unit. Another embodiment provides a method for placing the unit into a service position.

    摘要: The present technique relates to the distribution of power and data signals throughout a networked system. For example, three-phase power may be conducted to a device over a set of conductors. One of the conductors, however, may be configured to conduct, in conjunction with a neutral conductor, both one phase of three-phase power as well as data signals in accordance with a predetermined data communications protocol. As an alternate example, the present technique may comprise a set of a first power conductors configured to conduct three-phase power and a secondary power conductor which works in conjunction with an auxiliary conductor to conduct power and data signals. Additionally, the present technique provides for the maintenance data communications and a level of power upon the interruption of three-phase power to a particular component or device.

    摘要: A device is disclosed which may comprise a system generating a plasma at a plasma site, the plasma producing EUV radiation and ions exiting the plasma. The device may also include an optic, e.g., a multi-layer mirror, distanced from the site by a distance, d, and a flowing gas disposed between the plasma and optic, the gas establishing a gas pressure sufficient to operate over the distance, d, to reduce ion energy below a pre-selected value before the ions reach the optic. In one embodiment, the gas may comprise hydrogen and in a particular embodiment, the gas may comprise greater than 50 percent hydrogen by volume.
