Patent number: 9798041Abstract: A light curtain controller is provided that serially tunes or optimizes the operating margin of each channel during an initialization sequence. The controller measures and adjusts the operating margin for each emitter-receiver pair individually, such that the margin for each channel satisfies a defined optimization criterion. In this way, the light curtain's unique environmental and installation conditions are taken into account when tuning each channel. By individually tuning each emitter-receiver pair, the operating margin of each channel is set sufficiently high to ensure accurate object detection, while excessive margin is limited to prevent signal processing errors, such as those associated with adjacent-channel signal bleed-through, susceptibility to internal and external noise, etc.Type: GrantFiled: December 22, 2014Date of Patent: October 24, 2017Assignee: Rockwell Automation Technologies, IInc.Inventor: George Rollins

Publication number: 20070199047Abstract: System(s) and method(s) that facilitate utilizing biometric sensors (e.g., fingerprint, hand scan, voice recognition . . . ) in manufacturing systems in order to maintain accurate safety audit trails. A safety audit system, utilizing a biometric sensing device, facilitates determining if a user is allowed to access and change the configuration of the manufacturing system. Once a user is allowed to change the configuration (e.g., programmable electronics, tooling changes, software updates, etc.) the changes are automatically recorded in a safety audit database. Automatic storage of configuration changes mitigates manual recording of changes thereby enhancing the safety audit data often necessary to meet safety standards for manufacturing systems.Type: ApplicationFiled: February 23, 2006Publication date: August 23, 2007Applicant: Rockwell Automation Technologies, Inc.Inventors: Anthony Gibart, James Dogul, Richard Galera, George Rollins, Derek Jones, George Schuster, Suresh Nair, Ray Delcher
