Publication number: 20240119993Abstract: A memory controller monitors memory command selected for dispatch to the memory and sends commands controlling a read clock state. A memory includes a read clock circuit and a mode register. The read clock circuit has an output for providing a hybrid read clock signal in response to a clock signal and a read clock mode signal. The read clock circuit provides the hybrid read clock signal as a free-running clock signal that toggles continuously, and as a strobe signal that is active only in response to the memory receiving a read command.Type: ApplicationFiled: December 20, 2023Publication date: April 11, 2024Applicant: Advanced Micro Devices, Inc.Inventors: Aaron John Nygren, Kathik Gopalakrishnan, Tsun Ho Liu

Patent number: 10670738Abstract: A portable detection apparatus can include a housing, a first detector for detecting ionizing radiation from a first subject and a second detector within the housing for the detecting the background radiation. A shield within the housing can surround the first and second detectors and define a shield aperture around the first and second detectors for radiation from the subject to enter the housing. A radiation blocking member can substantially block at least a portion of the ionizing radiation from reaching the second detector, whereby radiation detected by the second detector comprises substantially only the background radiation. A processor module can be connected to the first and second detectors for determining the amount of ionizing radiation detected by the first detector attributable to secondary radiation.Type: GrantFiled: May 8, 2018Date of Patent: June 2, 2020Assignee: Atomic Energy of Canada Limited / Energie Atomique Du Canada LimiteeInventors: Xiongxin Dai, Liqian Li, Guy Jonkmans, Aaron Ho

Patent number: 8801571Abstract: A machine powertrain includes an engine operably connected to a torque converter and a transmission. A switch associated with the torque converter provides a locking signal indicative of a locked or unlocked condition of the torque converter. A throttle sensor associated with the throttle provides a throttle signal. An electronic controller receives the locking signal and the throttle signal, and controls operation of the engine at least partially based on the throttle signal and the locking signal. The electronic controller determines whether a locked or unlocked condition of the torque converter is present based on the locking signal, determines whether a part throttle operating condition or a full throttle operating condition is present based on the throttle signal, and selects a load-control power curve when the part throttle operating condition is present and when the torque converter switches from the unlocked to the locked condition.Type: GrantFiled: November 28, 2011Date of Patent: August 12, 2014Assignee: Caterpillar Inc.Inventors: Sairam Velamakanni, Aaron Ho, Catrina Swan, Warren Pepper, Douglas Carlson
