Publication number: 20240114150Abstract: A display processing device includes a display device interface and a processing unit. The processing is configured to transition at least a first component of the display processing system into a low-power state in response to an active region of a first video frame of a plurality of video frames having completed. A second component of the display processing device is configured to maintain a temporal count value corresponding to a current frame line of the plurality of video frames, and further to generate a first signal in response to the temporal count value corresponding to a first trigger value. The first signal causes the at least first component to transition out of the low-power state.Type: ApplicationFiled: September 29, 2022Publication date: April 4, 2024Inventors: Wing-Chi Chow, Yee Shun Chan, Nicholas James Chorney, Minghua Zhu

Patent number: 11928112Abstract: Systems and methods are provided that use a trained process to reply to a request comprising query data defining a query and context data defining contextual factors for the query from a device. The query is answered by one or more selected APIs of a plurality of APIs that invoke respective services to prepare a response. The trained process determines an execution plan responsive to the query data and the context data and is configured using training to define execution plans comprising selected APIs where a particular API is selected for the plan if it answers at least a portion of the query and the selected APIs together prepare the response optimized for the device according to the context data. The plan is provided to an execution component to execute the plan using the selected APIs and send the response to the requesting device.Type: GrantFiled: April 23, 2021Date of Patent: March 12, 2024Assignee: The Toronto-Dominion BankInventors: Milos Dunjic, Martin Albert Lozon, David Samuel Tax, Arthur Carroll Chow, Peter Glen Nairn, Edward James Hood, John Jong-Suk Lee, Arun Victor Jagga

Publication number: 20220233335Abstract: A minimally invasive surgical procedure for replacing a hip joint is provided. A main incision is initiated at a point being a projection of a tip of a greater trochanter and extends proximally about a distance in the range of from 1 cm to 8 cm in line with the femoral axis. An inline capsulotomy is performed, while keeping muscles and posterior capsule intact, to expose the hip joint capsule for accessing the hip joint. The femoral canal is prepared for receipt of a femoral implant. The femoral head is resected and removed out of the acetabulum. A step of acetabular preparation is performed using a retractor comprising two tip rails, each tip rail having a plurality of tines. Related tools, devices, systems and methods are also provided.Type: ApplicationFiled: April 11, 2022Publication date: July 28, 2022Applicant: MicroPort Orthopedics Holdings Inc.Inventor: James Chow

Patent number: 9823992Abstract: Dynamic program analysis is decoupled from execution in virtual computer environments so that program analysis can be performed on a running computer program without affecting or perturbing the workload of the system on which the program is executing. Decoupled dynamic program analysis is enabled by separating execution and analysis into two tasks: (1) recording, where system execution is recorded with minimal interference, and (2) analysis, where the execution is replayed and analyzed.Type: GrantFiled: September 26, 2008Date of Patent: November 21, 2017Assignee: VMware, Inc.Inventors: James Chow, Tal Garfinkel, Peter M.

Patent number: 9283241Abstract: Disclosed is a medical device treated with a phenolic compound and a process for treating a device with the phenolic compound. For example, a collagen or elastin-based scaffold can be treated with pentagalloyl glucose (PGG). The treated scaffold can become resistant to glycoxidative stress associated with advanced glycation end products (AGEs) that are present in a hyperglycemic environments associated with diabetes mellitus. The treated scaffold can exhibit a reduced increase in stiffness as compared to an untreated scaffold. The treated scaffold can also exhibit reduced inflammation without negatively affecting the ability of the scaffold to remodel in vivo.Type: GrantFiled: July 10, 2013Date of Patent: March 15, 2016Assignee: Clemson UniversityInventors: Agneta Simionescu, Dan Simionescu, James Chow

Patent number: 8719800Abstract: A virtual machine system decouples dynamic program analysis from program execution. Program analysis is decoupled from program execution through the use of a virtual machine to record program execution and an analysis platform to replay and analyze the program execution. Optimization techniques are applied to prevent the analysis platform from falling too far behind the program execution platform during replay.Type: GrantFiled: September 26, 2008Date of Patent: May 6, 2014Assignee: VMware, Inc.Inventors: James Chow, Tal Garfinkel, Peter M.

Patent number: 8656222Abstract: The execution behavior of a selected application is recorded for subsequent replay. During recording, only those portions of memory that are accessed by the selected application are stored. As a result, the amount of data that is stored during the recording session is reduced and data that is not necessary for replaying the selected application, which may include possible sensitive and personal information, are not stored.Type: GrantFiled: July 30, 2009Date of Patent: February 18, 2014Assignee: VMware, Inc.Inventors: James Chow, Tal Garfinkel, Dominic Lucchetti

Decoupled dynamic program analysis is enabled by separating execution and analysis into two tasks: (1) recording, where system execution is recorded with minimal interference, and (2) analysis, where the execution is replayed and analyzed. Recording and analysis are carried out on heterogeneous systems so that they can be separately optimized.Type: GrantFiled: September 26, 2008Date of Patent: January 8, 2013Assignee: VMware, Inc.Inventors: James Chow, Tal Garfinkel, Peter M.

Patent number: 8321842Abstract: Replay-time-only functionalities in a computer program are executed only during replay in a virtual machine and are skipped outside of replay. If a replay-time-only functionality is detected during the replay of a program execution in a virtual machine, the replay may be paused and the virtual machine state may be saved. The replay-time-only core functionality is executed. When this execution is complete, a prior state of the virtual machine may be restored and the replay may be resumed.Type: GrantFiled: June 27, 2008Date of Patent: November 27, 2012Assignee: VMware, Inc.Inventors: Min Xu, Dmitry Grinberg, Vyacheslav Malyugin, Petr Vandrovec, Ganesh Venkitachalam, Boris Weissman, Andrew Biggadike, James Chow
