摘要:
A vacuum control system allows the vacuum to be turned on and off automatically based on the operation of an associated power tool. The vacuum is able to run at full power without sacrificing power to the power tool itself. Additionally, a pneumatic power tool may be used to control the operation of the vacuum.

A system for characterizing high power electron beams at power levels of 10 kW and above is described. This system is comprised of a slit disk assembly having a multitude of radial slits, a conducting disk with the same number of radial slits located below the slit disk assembly, a Faraday cup assembly located below the conducting disk, and a start-stop target located proximate the slit disk assembly. In order to keep the system from over-heating during use, a heat sink is placed in close proximity to the components discussed above, and an active cooling system, using water, for example, can be integrated into the heat sink. During use, the high power beam is initially directed onto a start-stop target and after reaching its full power is translated around the slit disk assembly, wherein the beam enters the radial slits and the conducting disk radial slits and is detected at the Faraday cup assembly. A trigger probe assembly can also be integrated into the system in order to aid in the determination of the proper orientation of the beam during reconstruction. After passing over each of the slits, the beam is then rapidly translated back to the start-stop target to minimize the amount of time that the high power beam comes in contact with the slit disk assembly. The data obtained by the system is then transferred into a computer system, where a computer tomography algorithm is used to reconstruct the power density distribution of the beam.

Crates may be positioned in stacked arrangements for use and nested arrangements for storage. The nested arrangements may be more compact to facilitate more efficient storage of the crates when not in use. The crates may include one or more features that may be sized and configured to align and/or interlock the crates when in the stacked arrangement and/or the nested arrangement.

A pallet may include a first portion and a second portion that may be arranged in a use position. The first and second portions may also be arranged in one or more nested positions that may be more compact than the first position to help facilitate more efficient storage of the portions. The portions may also include one or more magnets that may be used to help secure the portions in the use position and/or the nested positions. The portions may include one or more interlocking and/or engaging features that may be used to help secure the portions in the use position and/or the nested positions. If desired, the first and second portions may be sized and configured to be independently used as pallets.

A low power electron beam system can be utilized for micro welding, brazing, or heating a workpiece and as an imaging system for precise positioning of a micro electron beam with regard to a workpiece. A filament system produces a micro electron beam, which is then focused onto the workpiece. In the welding mode, the micro electron beam is used to melt the workpiece and produce a weld. When switched to the imaging mode, the backscattered or secondary electrons produced by the interaction between the micro electron beam and the work piece are captured and converted into an image of the workpiece. The resulting image formed from these captured electrons is used as an aid in the precise positioning of the micro electron beam and inspection of the workpiece.

A method and system for creating distributed applications without programming is disclosed. A Connection Editor interacts with an interface manager attached to each program in the visual development system. The interface manager allows connections to be made using the Connection Editor between the compatible properties of disparate programs by a visual process. Upon connection, the interface manager automates data flow between disparate properties without requiring any additional programming. Furthermore, the interface manager allows for dynamic properties to be exposed based on the run-time discovery of data.

摘要:
The present invention relates to a method and system for automatically focusing an electron beam. Such an invention is based on a Faraday Cup diagnostic system, often a Modified Faraday Cup (MFC) system that enables tomographic reconstruction of the beam so as to measure beam parameters. Such a reconstruction method and system is automated using a servo-feedback loop to determine, for example, power distributions of the beam so as to provide appropriate adjustments to system controls to enable desired beam focus conditions.
