Patent number: 8272037Abstract: The invention provides an apparatus and a method for improving the control of access by a terminal device in a WLAN environment having an access point for determining whether the device utilizes an IEEE 802.1x protocol by the access point communicating to the device, a packet, whereby if the devices utilizes a IEEE 802.1x protocol the device appropriately responds and otherwise the access point determines that the terminal device protocol does not employ a IEEE 802.1x protocol and selects an authentication mechanism compatible with the terminal device. If the device is not an IEEE 802.1x client, an IP packet filtering is configured to redirect a user HTTP request to a local server, and when the HTTP requests are thereby redirected, the HTTP server presents the terminal device with information specifically related to the browser based authentication.Type: GrantFiled: March 12, 2004Date of Patent: September 18, 2012Assignee: Thomson LicensingInventors: Junbiao Zhang, Saurabh Mathur

Patent number: 6138818Abstract: A workpiece inversion system for orienting a workpiece in a conventional milling machine or the like. The workpiece is securely attached to a pallet. The pallet is of uniform design to provide a standard interface for presenting the workpiece to the milling machine. The pallets are transported to the milling machine where a combination of parts senses the pallet orientation. Upon arrival to the input station the pallet mates with an inverting receptor adjacent the input station. An actuator rotates the pallet 180 degrees thereby inverting the pallet and the attached workpiece. The inverted pallet is moved onto an inverted linear actuator disposed within the volume above the milling head. The inverting receptor returns to it original position to receive another workpiece. The inverted workpiece is moved through the machining area. As machining occurs, debris dislodged by the force of forced oil lubrication and gravity will fall away from the workpiece.Type: GrantFiled: November 23, 1998Date of Patent: October 31, 2000Assignee: Green Technologies Inc.Inventor: Stephen C.

Patent number: 5113677Abstract: In conventional fabrication manufacture the thickness of the steel plates are often determined by the metal section required at the weld joints. The subject apparatus and method overcomes this problem by selectively forming a thickened edge along the edge of a thinner steel plate which can now be limited to the thickness required to withstand the stresses on the fabrication. The thickened edge is produced by passing a plate supported on a table through a forming apparatus having a forming roller. The table is movable in an oblique direction relative to the plate so that the shape of the thickened edge may be varied. The forming apparatus and table are automatically controlled to produce a thickened edge of a desired shape intermittently or continuously along a linear or non-linear edge of the plate.Type: GrantFiled: May 9, 1991Date of Patent: May 19, 1992Assignee: Caterpillar Inc.Inventors: Dennis L.

Patent number: 4739545Abstract: By operating a Z direction position adjustment mechanism by a driving motor, a Z table movable in the X and Y directions can be moved in a Z direction while maintaining its horizontal condition. Vibrations caused in the Z table when the Z table is moved at a high speed in the X and Y directions are damped by vibration damping means provided between the Z table and a base bed fixed to a coarse adjustment table which is mounted on a base and driven in the X and Y directions. Improvement in the accuracy of positioning in the X and Y directions is achieved, as well as a vibration damping effect. A chuck holding member is formed on the table to hold a chuck by suction which in turn holds a mounted member by suction, thereby making the exchange of the chuck easy and preserving the parallelism of the upper surface of the chuck.Type: GrantFiled: February 26, 1987Date of Patent: April 26, 1988Assignee: Nippon Seiko Kabushiki KaishaInventor: Hideaki Oyanagi
