Patent number: 5793634Abstract: Procedures for adjusting or reseting the pressure used to swage needles to suture at a needle swaging station. The forces required to break the sutures from the needles are measured and added to a data base; and each time a value, or sample, is added to that data base, an average of all the sample values in the data base is calculated. Each time an average value is calculated, that value is compared to a first range, referred to as a reject range. If any calculated average value falls outside that reject range, then the swaging pressure is adjusted and the procedure is restarted, with a new, or empty, data base. Also, once the sample reaches a given size, such as eight or nine samples, the calculated average values are also compared to a second range, referred to as an accept range, and which is within and narrower than the reject range. If a calculate average value is within this accept range, the swaging pressure is considered acceptable and the procedure terminates immediately.Type: GrantFiled: February 21, 1997Date of Patent: August 11, 1998Assignee: Ethicon, Inc.Inventors: David D.

Patent number: 5771553Abstract: An error reduction and accommodation method and system can be used in an automated assembly environment. This method and system use a simple localized calibration process devised to improve similarity between an actual device and a simulated model when an off-line programming technique is used. The system uses grid-hole tables with modular fixtures holding the workpieces. The grid-hole table has round holes instead of screw holes or T-slots and allows modular fixtures with round pins to be placed on the grid-hole table with greater precision. A compliant coupling which is able to accommodate any small error in the system and when used with any end-tool, allows the assembly robot to carry out tasks within the modular system. The use of the grid-hole table and modular fixtures allows the robot, once taught the grid-hole table and the modular fixtures, to be subsequently programmed off-line to carry out any tasks with any standardized modular fixture placed any where on the grid-hole table.Type: GrantFiled: October 3, 1996Date of Patent: June 30, 1998Assignees: National University of Singapore, Nanyang PolytechnicInventors: Tian Soon Sim, Kah Bin Lim, Marcelo H.

Patent number: 5704110Abstract: A device for crimping a plastically deforming metal pole shoe (1) around the end (2) of a cable that has been inserted into it. The device comprises an anvil (3), a die (4), a sensor (5), and a comparator (6). The shoe is placed on the anvil and the die is advanced toward it, deforming the shoe. The sensor emits a signal once the shoe has been deformed to the maximum, and the comparator compares the signal with a reference and emits either an "accept" signal or a "reject" signal. The "reject" signal emitted by the comparator actuates a cable-end trimmer that cuts part-way or all the way through the cable. Consequently, the device will always either acceptably crimp pole shoes to the ends of cables or reliably indicate defective connections.Type: GrantFiled: September 11, 1996Date of Patent: January 6, 1998Assignee: Carl FreudenbergInventors: Anton Erhard, Werner Haag
