摘要： A parallelized sparse field method for segmenting a volume dataset is provided. Using a processor a level set field within a multi-dimensional dataset comprising a plurality of voxels is initialized in parallel operation. The multi-dimensional dataset is indicative of an object. An initial set of active voxels is then generated in parallel operation in dependence upon the initialized level set field. New active voxels are determined in parallel operation. Duplicate active voxels are then removed in parallel operation, followed by compacting the active voxels in parallel operation. The process is repeated until a quantitative stopping criterion is met and level set segmentation data indicative of a feature of the object are determined in dependence upon the level set field.

摘要： Methods and systems provide the wireless use of a desktop computer through a lightweight long-range mobile computing device with extended battery life and no writeable or user-accessible persistent data storage, such as a hard drive, which could be detrimental if lost. The light-weight mobile computing may not run a full operating system, thereby reducing overhead and increasing speed. The mobile computing device provides mobility while providing access to information on a desktop computer. Since some components of conventional laptops are not needed, it may be smaller and/or have lighter weight, and provide extended battery life, while providing greater security by avoiding the risk of data loss. These systems provide a lightweight mobile wireless KVM device (e.g., a small “notebook” computing device or tablet computer device) to connect to desktop computers. These lightweight, mobile computing devices may provide “instant on” capabilities avoiding the start up time of normal laptop computers.

摘要： The present invention relates to a method and system for processing a volumetric dataset for providing close-up visualization of a subset therefrom. A volumetric dataset is processed based on a dual access gradient quantization data structure. The data structure is generated in a fast pre-processing stage and provides substantially immediate access to a quantized gradient using either an index or an arbitrary normalized vector. The method provides a clear, enlarged high-resolution image of a user selected region of interest at interactive rates and allows the user to freely move and visualize the region of interest within the volumetric dataset and with any orientation.

摘要： Internal structures, features and properties in volumetric datasets are mostly obscured and hidden. In order to reveal and explore them, appropriate tools are required to remove and carve the occluding materials, isolate and extract different regions of interest. A framework of interactive tools are provided for real-time volume manipulation, sculpting, segmentation, and visualization. A GPU-based point radiation technique provides as a fundamental building block to create a collection of high-quality volume manipulation tools for direct drilling, lasering, peeling, cutting, and/or pasting. Interactive parallel region growing segmentation is described that allows multiple seeds planting by direct sketching on different volumetric regions with segmentation results dynamically modified during the process. The point radiation technique creates high-quality real-time feedback of the segmented regions during the seeded growing process.

摘要： In order to vary the timing of the ignition of an air/fuel mixture in a cylinder of an internal-combustion engine as a function of engine speed, a flip-flop is set by an engine-controlled switch at a predetermined point t.sub.0 in the cycle, in a position preceding by an angle .alpha..sub.0 the upper-dead-center position of an associated piston, to effect a rapid discharge and to start a slow recharge, at constant rate, of a capacitor C.sub.1 forming part of a time/voltage converter. The maximum voltage attained by this capacitor at the end of a cycle, as a measure of cycle length T, is registered in an ancillary capacitor C.sub.3 as another capacitor C.sub.2, forming part of a voltage/time converter, also begins charging at time t.sub.0 at a rate making the charges of capacitors C.sub.2 and C.sub.3 equal on or before the attainment of the UDC position. This equality is detected by a comparator which thereupon, at a time t.sub.0 +t.sub..gamma., resets the flip-flop to trigger an igniter for the associated cylinder. The charging rate of capacitor C.sub.2 may be modified by one or more sensing circuits responsive to external parameters and/or by one or more threshold circuits upon the charge of capacitor C.sub.1 or C.sub.2 reaching a predetermined level. Capacitors C.sub.2 and C.sub.3 are discharged upon the resetting of the flip-flop, the recharging of capacitor C.sub.3 beginning shortly thereafter.

摘要： A method for segmenting a volume dataset is provided. During initialization a level set field within a volume dataset is initialized and an initial set of active voxels is determined in dependence upon the initialized level set field. In an iteration process the level set field for the set of active voxels is updated followed by updating of the set of active voxels. The iteration is continued until the number of active voxels is less than a predetermined threshold. Level set segmentation data are then determined in dependence upon the level set field and provided for, for example, graphical display or storage.

摘要： Methods and systems are provided that allow a user to remotely access another computer and view its desktop without regard to whether that desktop has a relatively static image typical of a computer desktop, or whether it is playing a video, such as from a DVD. Relatively static screens may be displayed along with full motion video in such systems. These systems may also provide for both short mouse lag time when full motion video is displayed. In one implementation, hardware and firmware captures and encodes the video from the remote computer, and software on the client computer decodes the encoded video and displays it to the user.
