Abstract: Applications which function under a first operating system also function when it becomes necessary to call into action a second operating system due to provision having been made for configuration and other settings necessary to the execution of such applications (here generically called policy settings or policy source data) to be made available to the second operating system.

Abstract: In a hypervisor-based computing system, each guest operating system (GOS) is associated with multiple plug-in modules, with each module being configured to execute a respective function. The hypervisor also includes plug-in modules mirroring those of the GOS to provide for enhanced functionality on a module-by-module basis.

Abstract: An apparatus for generating and manipulating a high-pressure fluid jet includes an assembly coupled to a motion assembly that imparts motion to the assembly along one or more axes. The motion assembly includes two motors coupled together to form a gimbal wrist, each motor having an axis of rotation. The two axes of rotation of the two motors can be perpendicular to each other, but are not necessarily aligned with the manipulator's axes of motion. The high-pressure fluid assembly incorporates a swivel that can rotate about two axes which may be parallel to the two motors' axes of rotation, allowing the high-pressure tubing contained therein to follow the motion imparted by the gimbal wrist of the motion assembly.

Abstract: Methods and systems for automating the control of fluid jet orientation parameters are provided. Example embodiments provide a Dynamic Waterjet Control System (a “DWCS”) to dynamically control the orientation of the jet relative to the material being cut as a function of speed and other process parameters. Orientation parameters include, for example, the x-y position of the jet along the cutting path, as well as three dimensional orientation parameters of the jet, such as standoff compensation values and taper and lead angles of the cutting head. In one embodiment, the DWCS uses a set of predictive models to determine these orientation parameters. The DWCS preferably comprises a motion program generator/kernel, a user interface, one or more replaceable orientation and process models, and a communications interface to a fluid jet apparatus controller. Optionally the DWCS also includes a CAD module for designing the target piece.

Abstract: A positron source, position sensing device, particularly with medical applications, in which positron induced gamma radiation is detected using a ring of stacked, individual scintillation crystals, a plurality of photodetectors, separated from the scintillation crystals by a light guide, and high resolution position interpolation electronics. Preferably the scintillation crystals are several times more numerous than the photodetectors with each crystal being responsible for a single scintillation event from a received gamma ray. The light guide will disperse the light emitted from gamma ray absorption over several photodetectors. Processing electronics for the output of the photodetectors resolves the location of the scintillation event to a fraction of the dimension of each photodetector. Because each positron absorption results in two 180.degree. oppositely traveling gamma rays, the detection of scintillation in pairs permits location of the positron source in a manner useful for diagnostic purposes.
