    摘要： A simulator for a switched electronic power converter circuit feeding a load/device uses a modified FAMNM solver. Provided is a method/system for reducing/eliminating spurious power losses and transients inherently caused by the FAMNM solver using an L/C element approach, wherein a switching device in the ‘on’ state is featured as an inductor L, and a switching device that is in the ‘off’ state is featured as either a capacitance C or series-connected resistance and capacitance R-C. The invention uses cross-initialization of the L/C switching elements to their final state of current and voltage when they change their conduction state. The correct cross-initialization is enabled from optional pre-stored tables of events and the system-states at the time of the cross-initialization. The inventive method is an enhancement over known Dommel and Pejovic type FAMNM solvers. The simulator applies to real-time or non-real time simulators and is suitable for all power converter topologies.

    摘要： An underbody cladding is provided for a two-track motor vehicle with wheel-controlling links as part of a rear axle for cladding the underbody. The underbody cladding at least partially extends in a substantially horizontal plane and extends in the direction of the outside of the vehicle close to an inner side of a rear wheel. The underbody cladding is divided into three sections, a front section, a central section and a rear section. The central section extends at least over a region below the wheel-controlling links and is connected at least over part of the width thereof to the front section and/or the rear section. The central section is designed in such a manner that the section can at least partially follow and/or yield to a vertical movement of the wheel-controlling links. The front and the rear section of the underbody cladding can in each case be arranged in a positionally fixed manner on the motor vehicle and cannot follow and/or yield to a vertical movement of the wheel-controlling links.

    摘要： In exemplary implementations of this invention, a computer-assisted, handheld machining tool allows even an inexperienced user to carve a complex 3D object, while maintaining artistic freedom to modify the sculpture from an initial CAD design. The tool prevents the user from unintentionally removing material from a volume defined by the CAD design. It does so by slowing or halting spindle rotation as the bit approaches or penetrates the protected volume. The user can override this protective feature. The tool may operate in at least three interaction modes: (i) a static mode in which a static CAD model is used, where the computer assists by preventing the user from damaging the static model; (ii) a dynamic mode where the computer dynamically modifies the CAD model during the sculpting process; and (iii) an autonomous mode where the computer can operate independently of the user, for tasks such as semi-automatic texture rendering.

    摘要： A system for analyzing IC layouts and designs by calculating variations of a number of objects to be created on a semiconductor wafer as a result of different process conditions. The variations are analyzed to determine individual feature failures or to rank layout designs by their susceptibility to process variations. In one embodiment, the variations are represented by PV-bands having an inner edge that defines the smallest area in which an object will always print and an outer edge that defines the largest area in which an object will print under some process conditions.

    摘要： A method is disclosed for representing road intersections as data. A database includes intersection object data entities that represent physical road intersections. Each intersection object data entity includes a maneuver list that identifies each permissible transversal of the intersection from each lane by which the represented intersection can be entered to each lane from which the intersection can be exited from the associated lane by which the intersection can be entered. Each transversal in the maneuver list indicates an entry lane, an exit lane, the geometry of a vehicle path connecting the entry and exit lanes, and an indication of a level of confidence associated with the specified geometry. The database can be used by a system in a vehicle to provide a safety-related function. The database is compatible with navigation-related applications that use a different data model to provide navigation-related functions.

    摘要： Methods for producing layout data for devices are described. One method includes using a genetic algorithm to determine a structure of a thermally.operated actuator. Reference system performance characteristics are received and structure genotypes produced, each structure genotype including geometric and thermal properties of each of a plurality of links in the microelectromechanical system, the geometric and thermal properties selected randomly. Respective system performance characteristics of the genotypes are simulated and respective fitness ratings determined with respect to the reference. A second population of structure genotypes is produced using the first population and the determined fitness ratings. The steps are iterated until one of the structure genotypes satisfies selected termination criteria. Layout data corresponding to the geometric properties in the one of the structure genotypes are automatically produced using the controller.
