Patent number: 11537118Abstract: The design of a novel digital controller for a motor driven aircraft arrestment system of the type used on aircraft carriers is described. The unique control and feedback design of the described controller has many advanced features, which provide many advantages over existing designs for controlling advanced arresting gear systems. Gain scheduling in engage/arrest controllers can be done based on estimated parameters such as speed, effective skew angle, and faults to allow optimized engage/arrest controllers, where the gain scheduling can be defined, discretely, for each “bin” as defined for a range of threshold values, or it can be defined, continuously, using interpolation and/or functions of speed and effective skew. Particularly, controller design gain values Kci and Kfi are picked to shape control loop transfer functions and dampen resonances in the aircraft arrestment system.Type: GrantFiled: July 9, 2021Date of Patent: December 27, 2022Assignee: Electro Standards LaboratoriesInventors: Raymond B Sepe, Jr., Yacine Boudria, Steven Bastien

Patent number: 6895380Abstract: An interactive voice actuated control system for a testing machine such as a tensile testing machine is described. Voice commands are passed through a user-command predictor and integrated with a graphical user interface control panel to allow hands-free operation. The user-command predictor learns operator command patterns on-line and predicts the most likely next action. It assists less experienced operators by recommending the next command, and it adds robustness to the voice command interpreter by verbally asking the operator to repeat unlikely commanded actions. The voice actuated control system applies to industrial machines whose normal operation is characterized by a nonrandom series of commands.Type: GrantFiled: March 2, 2001Date of Patent: May 17, 2005Assignee: Electro Standards LaboratoriesInventor: Raymond Sepe, Jr.
