Abstract: Described is a system that tracks enregistered memory locations. The system receives program object code that enregisters a memory location (e.g., a set of data at a given memory address) and executes the program code using a thread. Enregistering memory locations involves using additional registers to cache frequently used memory locations while the object code is executing, these additional registers being available on an architecture on which the program executes, but generally not available on an architecture for which the object code was generated. After enregistering the memory location, the system uses a table that identifies enregistered memory locations to track the associated memory address and a thread identifier for the thread. The system checks this table during memory accesses to ensure that other threads attempting to access an enregistered memory location receive a current value for the enregistered memory location.

In another example, a method includes mixing a plurality of carbon fiber filaments having a length between about 6.35 millimeters and about 50.8 millimeters in molten pitch to form a substantially homogeneous mixture of carbon fiber filaments within the molten pitch, wherein mixing the plurality of carbon fiber filaments does not substantially change an average length of the plurality of carbon fiber filaments.

Abstract: One embodiment of the present invention provides a system that accesses memory locations in an object-addressed memory system. During a memory access in the object-addressed memory system, the system receives an object identifier and an address. The system then uses the object identifier to identify a paged memory object associated with the memory access. Next, the system uses the address and a page table associated with the paged memory object to identify a memory page associated with the memory access. After determining the memory page, the system uses the address to access a memory location in the memory page.

Abstract: An occupancy sensor may control a load in response to its own operating conditions. In some embodiments, the occupancy sensor may include an energy storage device to operate the occupancy sensor when a load it controls is not energized. The occupancy sensor may energize the load to transfer energy from the load to the occupancy sensor when the amount of energy stored at the occupancy sensor reaches a threshold level. In some other embodiments, the occupancy sensor may include two sensing circuits and a connection to transfer energy from a load it controls to the occupancy sensor when the load is energized. The occupancy sensor may disable one of the sensing circuits when the load is not energized.

Abstract: A system and method are provided for inlining across protection domain boundaries with a system virtual machine. A protection domain comprises a unique combination of a privilege level and a memory address space. The system virtual machine interprets or dynamically compiles not only application code executing under guest operating systems, but also the guest operating systems. For a program call that crosses a protection domain boundary, the virtual machine assembles an intermediate representation (IR) graph that spans the boundary. Region nodes corresponding to code on both sides of the call are enhanced with information identifying the applicable protection domains. The IR is optimized and used to generate instructions in a native ISA (Instruction Set Architecture) of the virtual machine. Individual instructions reveal the protection domain in which they are to operate, and instructions corresponding to different domains may be interleaved.

Abstract: A patient-specific compensator is created from solid particulates on-site at a radiation treatment facility and then used there at that facility in conjunction with a radiation therapy machine to deliver radiation therapy to a cancer patient. After use, the compensator can be broken down into loose solid particulates at the facility, and another compensator can be created on-site at the facility from those particulates and used in the radiation treatment of a different cancer patient at the facility.

Abstract: A compensator is used with a radiation therapy machine to treat a cancer patient. A three-dimensional surface of the compensator is defined by obtaining a radiation dose requirement created by a treatment planning system associated with the radiation therapy machine and determining a plurality of grid elements based on that radiation dose requirement. At least one of a plurality of points on each of the plurality of grid elements is connected with at least one of the plurality of points on another one of the plurality of grid elements to form a representation of the three-dimensional compensator.

Abstract: A method of validating a compensator for use in a radiation therapy machine to treat a cancer patient involves determining a radiation treatment plan based on a compensator description file that includes data representative of an actual machined surface of the compensator. The plan includes operating parameters of the radiation therapy machine, and this plan is compared against actual radiation measurements taken during a non-patient test of the radiation therapy machine with the compensator mounted to the machine. If the comparison results in a match, the compensator is validated for use in the radiation therapy machine to treat the cancer patient.

Abstract: A system and method are provided for inlining a program call between processes executing under separate ISAs (Instruction Set Architectures) within a system virtual machine. The system virtual machine hosts any number of virtual operating system instances, each of which may execute any number of applications. The system virtual machine interprets or dynamically compiles not only application code executing under virtual operating systems, but also the virtual operating systems. For a program call that crosses ISA boundaries, the virtual machine assembles an intermediate representation (IR) graph that spans the boundary. Region nodes corresponding to code on both sides of the call are enhanced with information identifying the virtual ISA of the code. The IR is optimized and used to generate instructions in a native ISA (Instruction Set Architecture) of the virtual machine. Individual instructions are configured and executed (or emulated) to perform as they would within the virtual ISA.

Abstract: One embodiment provides a system that includes a processor with a unified cache structure that facilitates accessing translation table entries (TTEs). This unified cache structure can simultaneously store program instructions, program data, and TTEs. During a memory access, the system receives a virtual memory address. The system then uses this virtual memory address to identify one or more cache lines in the unified cache structure which are associated with the virtual memory address. Next, the system compares a tag portion of the virtual memory address with the tags for the identified cache line(s) to identify a cache line that matches the virtual memory address. The system then loads a translation table entry that corresponds to the virtual memory address from the identified cache line.
