Patent number: 11075046Abstract: A cable pull switch includes a polychotomous sensor configured to provide a reading of at least one of a plurality of values, the reading corresponding to a tension on a pull cable or a linear displacement of an end of a pull cable. A processor coupled to the polychotomous cable pull sensor configured to determine a rate of change of the value of the reading from the sensor and determine an occurrence of a cable pull event, the determination based on the determined rate of change of the value, and determine whether the rate of change of the value of an electrical resistance through the polychotomous cable pull sensor is below a threshold rate of change value, and adjust an upper pull threshold value to a new upper pull threshold value that is based on a present reading of the value of the electrical resistance through the strain gauge.Type: GrantFiled: May 12, 2020Date of Patent: July 27, 2021Assignee: Rockwell Automation Technologies, Inc.Inventors: Andrew L. Tsang, Burt Sacherski, Steven Robert Tambeau, Arvind Ananthanarayanan, James Edward Dogul, Todd Bubar

Patent number: 10152030Abstract: A safety relay configuration system for configuring safety functions to be carried out by a safety relay is provided. The configuration system comprises a number of features that facilitate intuitive and simplified configuration of an industrial safety relay, including but not limited to features that guide the user through the configuration process using an intuitive sequential procedure that provides feedback and prompts based on user interaction, enforce design consistency throughout the configuration project by intelligently limiting user selections, and visually organize configuration and status information in a manner that efficiently utilizes display space and allows the user to quickly evaluate available configuration options.Type: GrantFiled: December 9, 2014Date of Patent: December 11, 2018Assignee: Rockwell Automation Technologies, Inc.Inventors: Bradley A.

Patent number: 10072997Abstract: An apparatus for an imbalance test includes a strain measurement module that measures a strain voltage across terminals of a strain gauge. The strain voltage is representative of an amount of force on the strain gauge. The apparatus includes a test measurement module that measures a test voltage across the terminals of the strain gauge while a test resistor is connected in parallel with a resistor of the strain gauge. The test resistor is connected while the test measurement module measures the test voltage and is disconnected while the strain module measures strain voltage. The apparatus includes an average module that calculates an average strain voltage from two strain voltage measurements. The strain voltages are measured preceding and after the test voltage measurement. The apparatus includes a difference module that determines a difference voltage. The difference voltage is a difference between the average strain voltage and the test voltage.Type: GrantFiled: May 11, 2017Date of Patent: September 11, 2018Assignee: ROCKWELL AUTOMATION TECHNOLOGIES, INC.Inventors: Todd Bubar, Andrew L.
