Patent number: 11972116Abstract: A processing unit determines a first mapping relationship and a second mapping relationship, where the first mapping relationship indicates that an access rule of a first physical address is access forbidden, and the second mapping relationship indicates that an access rule of the first physical address is access allowed. The processing unit determines that a target mapping relationship is the first mapping relationship, sends a first access request to a memory control unit. The processing unit receives first exception information sent by the memory control unit, where the first exception information is sent when the memory control unit determines that the access rule of the first physical address in the target mapping relationship is access forbidden. The processing unit monitors a process based on the first exception information, switches the target mapping relationship; and re-sends the first access request to the memory control unit.Type: GrantFiled: March 26, 2020Date of Patent: April 30, 2024Assignee: Huawei Technologies Co., Ltd.Inventors: Jinfeng Yuan, Shengqiang Huang, Yongcun Gan

Patent number: 10851717Abstract: A system for actuating one or more engine valves for positive power operation and engine braking operation is disclosed. In a preferred embodiment, an exhaust valve bridge and intake valve bridge each receive valve actuations from two sets of rocker arms. Each valve bridge includes a sliding pin for actuating a single engine valve and an outer plunger disposed in the center of the valve bridge to actuate two engine valves through the bridge. The outer plunger of each valve bridge may be selectively locked to its valve bridge to provide positive power valve actuation. During engine braking, application of hydraulic pressure to the outer plungers may cause the respective valve bridges and outer plungers to unlock so that all engine braking valve actuations are provided from a rocker arm acting on one engine valve through the sliding pin.Type: GrantFiled: May 12, 2014Date of Patent: December 1, 2020Assignee: JACOBS VEHICLE SYSTEMS, INC.Inventors: Kevin P. Groth, Brian L. Ruggiero, Shengqiang Huang, Neil E. Fuchs, John J. Lester, Steven N. Ernest, Joseph Paturzo

Publication number: 20140251266Abstract: In controlling valve motions of an internal combustion engine, after determining that engine braking operation has been initiated, a deactivation mechanism disposed within a main valve train is activated thereby disabling conveyance of main valve events from a main valve motion source to a valve via the main valve train. Engine braking valve events are enabled for the valve, which may include two-stroke engine braking. Coupling mechanisms, including one-way coupling mechanisms, between adjacent rocker arms may be used in this manner.Type: ApplicationFiled: May 23, 2014Publication date: September 11, 2014Applicant: Jacobs Vehicle Systems, Inc.Inventors: Kristin V.
