Patent number: 9267625Abstract: A method of producing a seamless, composite tubular product includes centrifugally casting a metal or alloy into a tubular workpiece having an inner diameter. The method then centrifugally casts a corrosion resistant alloy in the inner diameter of the tubular workpiece to form a composite tubular workpiece having an inner diameter and an outer diameter. The inner diameter of the composite tubular workpiece is formed of the corrosion resistant alloy, and the outer diameter is formed of the metal or alloy. The method then subjects the composite tubular workpiece to at least about a 25% wall reduction at a temperature below a recrystallization temperature of the workpiece using a metal forming process. The metal forming process includes radial forging, rolling, pilgering, and/or flowforming.Type: GrantFiled: July 8, 2013Date of Patent: February 23, 2016Assignee: ATI PROPERTIES, INC.Inventor: Matthew V.

Patent number: 9254572Abstract: A robotic tool changer removably attaches a robotic tool to a robotic arm. The changer includes a tool module connected to the robotic tool, and a master module connected to the robotic arm. To attach and detach the robotic tool, the changer couples and uncouples the tool module and the master module. A master electrical signal module (ESM) affixes to the master module and a tool ESM affixes to the tool module. In accordance with design requirements, the changer applies the same power supply to both the master ESM and the tool ESM. The changer, however, selectively suppresses application of the power supply to the tool ESM, while maintaining application of the power supply to the master ESM, during the coupling or uncoupling of the master module and the tool module. In doing so, the changer enables such coupling and uncoupling, while also preventing the formation of transient electric arcs.Type: GrantFiled: May 4, 2012Date of Patent: February 9, 2016Assignee: ATI Industrial Automation, Inc.Inventor: Alexander Strotzer

Publication number: 20160037166Abstract: A method, system, and computer program product that exploits motion hints associated with rendered video frames. These motion hints are provided to a video encoder to guide a motion-compensation prediction process performed by the video encoder. Specifically, these motion hints can be used to better position a search window in a reference video frame to better capture the motion of a block of pixels in the reference video frame. Because the search window is better positioned in the reference video frame, the memory required to perform the encoding process can be reduced without sacrificing the level of encoded image quality.Type: ApplicationFiled: August 1, 2014Publication date: February 4, 2016Applicant: ATI Technologies ULCInventors: Khaled MAMMOU, Ihab M.A. AMER

Patent number: 9213381Abstract: A method of controlling voltage in a circuit is provided. Within the circuit, a block of an electrical component provides an indication that it desires to switch states (such as from off to on, on to off, or from one speed to another). The change in states requires a different current draw by the electrical component block. The indication is received by an electrical component that controls the voltage of the circuit. The electrical component that controls the voltage then issues a signal granting permission for the electrical component block to switch states. This permission signal is received by the electrical component and the electrical component block changes state.Type: GrantFiled: May 24, 2012Date of Patent: December 15, 2015Assignees: ATI Technologies ULC, Advanced Micro Devices, Inc.Inventors: Michael J.
