Method and apparatus for geometric variations to integrate parametric computer aided design with tolerance analyses and optimization
InactiveUS6963824B1Convenient investigationReadily apparentPosition fixationComputation using non-denominational number representationGraphicsComputer Aided Design
The objective of the invention is a bi-level method for modeling geometric tolerances compatible with the ANSI / ASME tolerance standard. At the local level, the model represents each tolerance-zone for a plane or an axis (line) as a tolerance map, and it includes the computational techniques that relate interdependencies between these regions and subregions within them. The model includes formulations for variations in size, form, orientation, position, and runout, and combinations of these, because all of these variations can be modeled using points, lines, and planes. Since variations in simple profiles that are formed from lines and circular arcs also can be described by such combinations, they too are includable in the formulation. The primary method is to overlay the geometry of tolerance-zones onto some traditional modes for representing planes, lines, and points. At the global level, the model inter-relates all frames of reference on a part or an assembly.

A method and system for computer aided design (CAD) is disclosed for designing geometric objects. The present invention interpolates and / or blends between such geometric objects sufficiently fast so that real time deformation of such objects occurs while deformation data is being input. Thus, a user designing with the present invention obtains immediate feedback to input modifications without separately entering a command for performing such deformations. The present invention utilizes novel computational techniques for blending between geometric objects, wherein weighted sums of points on the geometric objects are used in deriving a new blended geometric object. The present invention is particularly useful for designing the shape of surfaces. Thus, the present invention is applicable to various design domains such as the design of, e.g., bottles, vehicles, and watercraft. Additionally, the present invention provides for efficient animation via repeatedly modifying surfaces of an animated object such as a representation of a face.

Radiotherapeutic apparatus
ActiveUS8059782B2Limited lifetimeLow efficiencyHandling using diaphragms/collimetersX-ray/gamma-ray/particle-irradiation therapyRadiosurgeryImage resolution
The present invention seeks to provide a radiotherapeutic apparatus that mitigates the various problems found in the techniques such as tomotherapy, IMAT, IMRT and the like. It provides a radiotherapeutic apparatus comprising a source of radiation whose output is collimated by a multi-leaf collimator, and a patient support, the source being rotatable around the support and the support being translatable along the axis of rotation, thereby to move the source helically relative to a patient on the support. The leaves of the MLC are preferably oriented orthogonal to the axis of rotation, to simplify computation of the dose distribution. The apparatus thus moves the patient on the patient support system along the axis of rotation, in the longitudinal direction. Thus, the device has an effectively unlimited treatable volume in the longitudinal direction and avoids the limitations of IMAT and IMRT techniques whilst enabling the use of thin MLC leaves to give a high longitudinal resolution. The apparatus is preferably combined with an optimization system providing a computational service similar to that provided for IMAT and IMRT devices. Essentially the same computational techniques could be used, with appropriate changes to the input conditions and characteristic equations. The long aperture length (compared to tomotherapy) makes the radiation delivery efficient and therefore the delivery of high doses a practicality; hypofractionation and radiosurgery therefore become possible over large treatable volumes.
