Abstract: The present invention provides a reliable, high-repetition rate, production line compatible high energy photon source. A very hot plasma containing an active material is produced in vacuum chamber. The active material is an atomic element having an emission line within a desired extreme ultraviolet (EUV) range. A pulse power source comprising a charging capacitor and a magnetic compression circuit comprising a pulse transformer, provides electrical pulses having sufficient energy and electrical potential sufficient to produce the EUV light at an intermediate focus at rates in excess of 5 Watts. In preferred embodiments designed by Applicants in-band, EUV light energy at the intermediate focus is 45 Watts extendable to 105.8 Watts.

Abstract: An apparatus and method is described which may comprise a plasma produced extreme ultraviolet (“EUV”) light source multilayer collector which may comprise a plasma formation chamber; a shell within the plasma formation chamber in the form of a collector shape having a focus; the shell having a sufficient size and thermal mass to carry operating heat away from the multilayer reflector and to radiate the heat from the surface of the shell on a side of the shell opposite from the focus. The material of the shell may comprise a material selected from a group which may comprise silicon carbide, silicon, Zerodur or ULE glass, aluminum, beryllium, molybdenum, copper and nickel. The apparatus and method may comprise at least one radiative heater directed at the shell to maintain the steady state temperature of the shell within a selected range of operating temperatures.

Abstract: An DPP EUV source is disclosed which may comprise a debris mitigation apparatus employing a metal halogen gas producing a metal halide from debris exiting the plasma. The EUV source may have a debris shield that may comprise a plurality of curvilinear shield members having inner and outer surfaces connected by light passages aligned to a focal point, which shield members may be alternated with open spaces between them and may have surfaces that form a circle in one axis of rotation and an ellipse in another. The electrodes may be supplied with a discharge pulse shaped to produce a modest current during the axial run out phase of the discharge and a peak occurring during the radial compression phase of the discharge. The light source may comprise a turbomolecular pump having an inlet connected to the generation chamber and operable to preferentially pump more of the source gas than the buffer gas from the chamber.

Abstract: A method and apparatus for identifying a device acting as a server on a network is disclosed which uses network data representing communications on the network. The network data contains source device, destination device, data transfer protocol and data volume information for each communication represented therein and may be collected by network traffic monitors or packet capture devices such as RMON2 probes on the network. Data relating to relevant server protocols is identified within the network data, and using the identified data, a device is determined to be acting as a server if it has the highest data volume for communications in which it is the source or destination device and which communications involve at least a threshold number of other devices. The method may be conveniently implemented in a computer program and may be used in conjunction with a network management application.

Abstract: Apparatus and method for use in a network of, for example, computers, for generating summary data, such as traffic summary information, from a plurality of data records, the data records having a different temporal basis, for example, one hour or one day or one week, and different start and end times. The summary data is generated for a requested time interval having a requested start time and a requested end time by selecting a data record with a record start time corresponding to the requested start and an end time as far as possible from the record start time but equal to or before the requested end time. The data from that selected data record is processed, and the initial time is then set to the end time of that particular data record and the process repeated. In this way one can gather and process such data with a minimum number of steps.

Abstract: A method graphically presents a selected group of data values of a series of data values in a predetermined presentation area. The largest data value within the selected group of data values is determined. A scaling factor for the determined largest data value to correspond with a lateral dimension of the presentation area is determined. The determined scaling factor is applied to all the data values in the group of data values. The scaled group of data values within the presentation area is graphically presented. Advantageously, the graphical presentation of the data values is scaled according to the data presented in the presentation area, thus maximizing the detail shown in the graphical representation. The method is preferably implemented in the form of a computer program.

Abstract: A method and apparatus for generating configuration files using policy descriptions is provided. The present invention provides a method of generating a binary configuration file by receiving an identification encoded filename, parsing the identification encoded filename to determine identification parameters, matching the identification parameters to a set of configuration policy data to create configuration file parameters, and generating the binary configuration file from the configuration file parameters. The identification encoded filename can be can be run through an authentication check to provide increased security. Once created, the binary configuration file can also be validated, providing increased integrity. In one aspect of the present invention implemented is provided on a TFTP server. In another aspect of the invention an LDAP server is queried for certain configuration policy data, the configuration policy data being optionally cached on the TFTP server.

Abstract: The toy wheel is made up of two flat discs having central openings and sandwiching a ring of foam-like material therebetween. A metal rim in turn surrounds the foam like material so that when the assembled wheel is rolled along a pavement, noise is generated by the metal rim. A driving rod includes a handle and stem portion terminating in a hook arranged to straddle the outer peripheral edges of the assembled wheel so that the wheel can be nudged along by the rod in rolling engagement with the ground. Psychedelic designs may be provided on the outer exposed faces of the wheel discs to provide a visual effect in addition to noise generated by the metal rim. Also, the relatively large central opening permits the use of the hook portion of the rod to engage within the central opening to capture the wheel should it get out of control.
