Patent number: 6385504Abstract: A mailing list is created including destination addresses for mailpieces to be submitted to a carrier service for delivery. A unique mailpiece identifier associated with mailpieces on the mailing list is generated by the carrier or other trusted third party. The unique mailpiece identifier is printed on the mailpiece with which it is associated. The -mailpieces with the printed unique identifier are submitted to the carrier service. The carrier service obtains the printed unique identifier from the mailpiece. The obtained unique identifier from each said mailpiece is utilized to verify that data associated with the mailpiece has been processed by the carrier or trusted third party. When the unique number has been obtained from the mailpieces, the carrier service, if desired, may note this fact in the carrier records to prevent reuse of the unique identifier.Type: GrantFiled: May 4, 1999Date of Patent: May 7, 2002Assignee: Pitney Bowes Inc.Inventors: Leon A.

Patent number: 6385496Abstract: A generic process control routine for a process control system is written to include alias names and dynamic reference parameters. Before execution of a process control function on a particular unit of the process control system, an instance of the generic routine is created, in which the alias names are replaced by parameters defined in an alias resolution table for the particular unit. The controller then executes the instantiated version of the generic routine to control operation of the unit. The generic routine can have multiple algorithms associated therewith, wherein each of the algorithms is designed to control different units having somewhat different hardware, even though these different units perform essentially the same function within the process control system. The generic routine may also be used with multiple classes of hardware that perform different functions within the process control system.Type: GrantFiled: March 12, 1999Date of Patent: May 7, 2002Assignee: Fisher-Rosemount Systems, Inc.Inventors: William G. Irwin, Robert B. Havekost, Dennis L. Stevenson, David L. Deitz

Patent number: 6381512Abstract: There is provided a molding-condition recovery device which may easily recover the molding condition having been applied in the past, and also permits the storage of the past molding conditions in a memory having small capacity. A reduction in required memory capacity of the modification history storage file is permitted by storing only data of a component subjected to setting modification, among the components of the molding condition, in a modification history storage file. The recovery of the past molding condition is made by replacing all the set values of the presently-applied molding condition or the data in a temporary file stored with all the set values of the first molding condition with data in the modification history storage file in sequence.Type: GrantFiled: May 27, 1999Date of Patent: April 30, 2002Assignee: Fanuc LTDInventors: Osamu Saitou, Kazuo Kubota

System and method of flexibly sorting and unloading finished parts during part manufacturing process
Patent number: 6377864Abstract: The present invention relates to a system and method therefor of sorting and unloading various pieces cut from sheet blanks which have different dimensions in a sheet metal fabricating environment. To achieve this end, prior to the production run, the various program routines whose operations for effecting the cutting of the sheet blanks are retrieved and the data relevant to the to be cut pieces are grouped and analyzed so that pieces of different dimensions cut in accordance with the different program routines are respectively allocated to the corresponding sorting addresses for unloading. Accordingly, different pieces with the same dimension cut from different program routines during the same production run are unloaded to the same location of the unloader area. Optimization of the unloading process and optimal utilization of the available loading space are thereby achieved.Type: GrantFiled: June 16, 1994Date of Patent: April 23, 2002Assignee: Finn-Power International, Inc.Inventor: Mikko Lindstrom -

Patent number: 6377866Abstract: A device operable to apply an identification mark to a semiconductor wafer and inspect the applied mark immediately after its application. Engraving information and wafer thickness data are suppled to an engraving device and the engraving operation applies the mark to the wafer accordingly. A camera then reads the applied mark as read information and a comparator compares the read information to the engraving information and an error is determined in an information processing device. In order to maintain efficient operation of the mark application process, the error determined in the information processing device is then used to control the engraving device as it applies identification marks.Type: GrantFiled: December 4, 1997Date of Patent: April 23, 2002Assignee: Shibaura Mechatronics CorporationInventors: Yoshiichirou Iwakiri, Susumu Honda
