    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.

    摘要翻译： 提供了一种用于在阳轴和阴轴或空心轴之间限定自形成套筒的技术。 自形成套筒可以防止在阳轴和中空轴之间的界面处的磨损和磨损，同时允许扭矩通过界面传递。 自成型套筒可由可固化液体制成，例如粘合剂或密封剂。 将套筒材料施加到中空孔，或者在组装步骤之前施加到阳轴或两者之间。 在自成型套筒固化或粘合之后，套筒不会从阳轴和中空孔之间的界面排出，流动或以其它方式被挤出，从而在接口处以最小程度的磨损和磨损提供持续的操作。 自成型套筒允许在大量操作之后拆卸配对的阳空心轴和空心轴，而不会有过大的力并且不会对轴和连接的机械造成显着的损坏。

    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.
