Publication number: 20250177067Abstract: Devices, systems and methods for detecting a position of an object with a robot surgical system having an articulable, separable camera stand. The surgical robot system may include a robot having a robot base with a robot arm and an end-effector coupled to the robot arm. The end-effector, surgical instruments, the patient, other objects, or any combination thereof, may be tracked via active and/or passive tracking markers. A camera, such as an infrared camera, a bifocal camera or a stereophotogrammetric infrared camera, is mounted on a separable camera stand and is able to detect the tracking markers when in use. Using the camera, the robot determines a position of the object from the tracking markers, which may be a three-dimensional position of the object or the markers. When convenient, the camera base may be assembled into the robot base, e.g., by sliding the camera base into the robot.Type: ApplicationFiled: February 3, 2025Publication date: June 5, 2025Inventors: David Cleary, Norbert Johnson, Kevin Zhang

Patent number: 12229541Abstract: Using a common reference address when processing calls between a native application binary interface (ABI) and a foreign ABI. Based on a caller calling using a reference address, a lookup structure is used to determine whether the reference address is within a memory range storing native code and that the callee is native, or a memory range not storing native code and that the callee is foreign. Execution of a callee is initiated based on one of (i) calling the callee using the reference address within an emulator when the caller is native and the callee is foreign; (ii) calling an entry thunk when the caller is foreign and the callee is native; (iii) calling an exit thunk when the caller is native and the callee is foreign; or (iv) directly calling the callee using the reference address when the caller is native and the callee is native.Type: GrantFiled: June 13, 2023Date of Patent: February 18, 2025Assignee: Microsoft Technology Licensing, LLCInventors: Pedro Miguel Sequeira De Justo Teixeira, Darek Josip Mihocka, Jon Robert Berry, Russell Charles Hadley, James David Cleary, Clarence Siu Yeen Dang

Patent number: 11828220Abstract: The present disclosure is directed toward an engine system and a multi-mode combustion method for an internal combustion engine using hydrogen as a fuel. The engine system comprises a combustion system including a step-lipped piston bowl, a cover opposing the piston bowl, a hydrogen direct injector, and a radially asymmetrical pre-chamber partially opposite the lip of the piston bowl. The multi-mode combustion method includes injecting hydrogen and air a first time into the combustion system through the hydrogen direct injector, and jet igniting the fuel-air mixture in the combustion system. The injecting occurs during an intake stroke at low loads, and during a compression stroke at medium and high loads, Injecting hydrogen and air into the combustion system a second time via the hydrogen direct injector occurs either during or after jet-igniting, the hydrogen and air being at least partially ignited by compression.Type: GrantFiled: December 30, 2022Date of Patent: November 28, 2023Assignee: SAUDI ARABIAN OIL COMPANYInventors: Yu Zhang, Nayan Engineer, David Cleary

Patent number: 11720335Abstract: A hybrid binary executable under both native processes and compatibility (e.g., emulated) processes. When the hybrid binary is loaded by a native process, the process executes a native code stream contained in the binary directly on a processor. When the hybrid binary is loaded by a compatibility process, the process executes an emulation-compatible (EC) code stream directly on a processor. The hybrid binary format supports folding of code between the native code stream and the EC code stream. The hybrid binary comprises a set of memory transformations which are applied to image data obtained from the binary when the hybrid binary executes under the compatibility process.Type: GrantFiled: December 14, 2021Date of Patent: August 8, 2023Assignee: Microsoft Technology Licensing, LLCInventors: Pedro Miguel Sequeira De Justo Teixeira, Darek Josip Mihocka, Jon Robert Berry, Russell Charles Hadley, James David Cleary, Clarence Siu Yeen Dang
