Abstract: A computer-implemented method includes receiving a digital representation of an image and generating CAD sketches from it. The number of surfaces in a CAD model depends upon the number entities at the sketch level. The method keeps the number of created sketch entities and constraints to a minimum. The method includes a scalable approach for a range of images. Each contour is represented by a sequence of points following a path corresponding to a boundary in the image. The method includes classifying each point in a particular one of the contours as a curve region or a corner region contour point, thereby segmenting the contour into plurality of curve regions separated by corner regions. The method includes optimally fitting a curve to each one of the curve regions to create the best possible representation of the curve region. Additionally, the refine algorithm automatically improves the fit wherever needed.

Abstract: A method in a computer aided drafting application for replicating a component mating in a modeled assembly includes examining constraints and geometry surrounding a selected component of the component mating in a first surface of the assembly. A first descriptor with a plurality of numerical characteristics of the constraints and geometry is captured. The first descriptor is set as a first seed descriptor. A potential first target geometry in the region of the first face is examined and a first target descriptor is computed according to the first target geometry. If first seed descriptor matches the first target descriptor, an instance of a first target component is created according to the first target descriptor.

Abstract: A method for selecting a plurality of edges or faces of a displayed modeled object in a computer-aided design (CAD) system extracts a plurality of features, each feature including a measurable numeric property of one or more of edges or faces of the modeled object. The features are scaled, and a selection of a seed edge or a seed face is received. A suggested edge or face is chosen based upon the seed edge or seed face, and a graphical indication of the suggested edge or face is displayed on the modeled object.

Abstract: A method for mating a user selected first component of a computer aided drafting application assembly to a second component detects a user drag of the first component. A user pause of the drag for a predetermined interval is detected at a pause location. A plurality of first component surfaces and a plurality of second component surfaces are identified. The first component surfaces are compared with the second component surfaces, and a mating is suggested between a first component surface and a second component surface.

Abstract: A computer-based method includes enabling a user to create or select a geometric entity in a design in a computer-aided design program, predicting a location and orientation in the design for a copy of the geometric entity, and displaying, as a suggestion to the user, a visual representation of the copy of the geometric entity in the predicted location and orientation in the design.

Abstract: A readily portable imaging system for use in the field and, more particularly to an electronic camera and electronic printer housed and readily connectable with respect to each other in the field, and wherein the electronic printer includes a film unit drive assembly that advances the film unit (self-developing type) past a stationary print head for emitting consecutive lines of image data on the film unit to effect progressive exposure on the film unit simultaneously as a fluid spread system spreads the processing fluid over the film unit to effect processing of exposed portions of the film unit.

Abstract: An electronic camera of the present invention includes a paper exit opening for removal of printed paper provided on the upper surface of the case of the camera main body, a protection sheet having a base end fixed to the inside of the paper exit opening, with a free end revertible to a wound-up roll shape retracted inside the case, and capable of being extended by the front end of the printed paper when the printed paper is transported from the case to the outside so that the protection sheet covers the photosensitive surface of the paper, and an open-and-close lid having one end edge axially supported to be rotatable to the case so that the paper exit opening is closed from the outside of the case when the protection sheet is retracted within the case. Further, the protection sheet includes a linking mechanism for linking the protection sheet to the open-and-close lid so that the open-and-close lid is opened or closed interlocked with a movement of the protection sheet.
