  • Publication number: 20250215846
    Abstract: Described is an engine with a camshaft having a single cam profile, a gas intake manifold, and an exhaust gas rebreather system for receiving an exhaust gas from the engine. The exhaust gas rebreather system includes a main exhaust gas outlet configured to receive the exhaust gas. An exhaust gas rebreather line of the exhaust gas rebreather system returns a portion of the exhaust gas in the main exhaust gas outlet to the gas intake manifold. A variable nozzle turbocharger having one or more variable nozzle vanes is in fluid connection with the main exhaust gas outlet. The exhaust rebreather system further includes an exhaust gas recirculation valve and a back pressure valve. The exhaust gas recirculation valve is disposed in the exhaust gas rebreather line and in fluid connection with the main exhaust gas outlet, and the back pressure valve downstream of the variable nozzle turbocharger.

  • Publication number: 20250177067
    Abstract: 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.

  • Patent number: 12229541
    Abstract: 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.

  • Publication number: 20240351422
    Abstract: A hybrid machine includes an engine, a first and second motor, a first and second generator, and a first and second geartrain. The engine generates power from a combustion reaction and includes an intake port, a combustion chamber, a piston, a crankshaft, and an exhaust port. The intake port receives air from an external environment. The combustion chamber mixes the air with fuel to create a mixture that is ignited. The piston actuates to rotate the crankshaft. The exhaust port delivers exhaust gases out of the engine. The first and second motors respectively include a first and second hub that rotate from supplied power. The first and second generators respectively generate power when a first and second shaft rotate. A first and second geartrain respectively connect to the first and second motors, the first and second generators, and the crankshaft to transmit power to a first and second wheel.

  • Patent number: 11980430
    Abstract: Embodiments of the present disclosure provide a surgical robot system may include an end-effector element configured for controlled movement and positioning and tracking of surgical instruments and objects relative to an image of a patient's anatomical structure. In some embodiments the end-effector may be tracked by surgical robot system and displayed to a user. In some embodiments the end-effector element may be configured to restrict the movement of an instrument assembly in a guide tube. In some embodiments, the end-effector may contain structures to allow for magnetic coupling to a robot arm and/or wireless powering of the end-effector element. In some embodiments, tracking of a target anatomical structure and objects, both in a navigation space and an image space, may be provided by a dynamic reference base located at a position away from the target anatomical structure.

  • Publication number: 20240138788
    Abstract: A portable medical imaging system and method, of which the system includes a movable station having a movable C-arm, an imaging signal transmitter attached to the movable C-arm, and an imaging sensor positioned generally opposite to the imaging signal transmitter and attached to the movable c-arm. The imaging sensor is configured to rotate relative to a point approximately on a center axis of the movable C-arm independently of the imaging signal transmitter, so as to change an angle of incidence for a signal transmitted from the imaging signal transmitter to the imaging sensor, and provide a field-of-view that is larger than the field-of-view of the imaging sensor at a single position.

  • Patent number: 11828220
    Abstract: 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.

  • Patent number: 11720335
    Abstract: 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.
