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.

When convenient, the camera base may be assembled into the robot base, e.g., by sliding the camera base into the robot.

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.

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.

The cable chain comprises split tubing and a plurality of links extending discretely along a length of the split tubing. Each link comprises a housing including an outer surface and an inner surface.

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.

Abstract: Using a common reference address when processing calls among a native ABI and a foreign ABI. Based on 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).

Abstract: A function is compiled against a first application binary interface (ABI) and a second ABI of a native first instruction set architecture (ISA). The second ABI defines context data not exceeding a size expected by a third ABI of a foreign second ISA, and uses a subset of registers of the first ISA that are mapped to registers of the second ISA. Use of the subset of registers by the second ABI results in some functions being foldable when compiled using both the first and second ABIs. First and second compiled versions of the function are identified as foldable, or not, based on whether the compiled versions match. Both the first and second compiled versions are emitted into a binary file when they are not foldable, and only one of the first or second compiled versions is emitted into the binary file when they are foldable.
