A method of generation of smoothly shaped, non-circular, curves by formation of multiple circular arcs. In the method, one draws a first circular arc which passes through two points and is tangent to a first line extending from a first point in the indicated direction. Next, one repeats the process by drawing a second circular arc which passes through one of the aforementioned two points and a third point and is tangent to an extending line. By utilizing of a common point for each of the two circular arcs one can generate a smooth, non-circular, curve from the end blending of the two circular arcs. By moving or deleting points, or by adding points, or by changing the defined directed tangent line, or by defining a directed tangent line at a different point, one can reconfigure the curve into the desired final curve. Several curves can be combined to generate a desired figure.

A system and method for reliability assessment and prediction of end items is provided herein. A reliability assessment program (RAP) in accordance with the present invention provides a reliability assessment of the new equipment and/or parts designed for in-field use by assessing the similarities and differences between the new equipment and the predecessor equipment. Predecessor end item field failure data is collected and analyzed to compare the degree of similarity between the predecessor fielded end item and the new design. Based on this comparison, an appropriate method of assessment is determined, for example, a similarity analysis process or a failure cause model. Both methods use models for comparison and generate an appropriate report expressing the failure rate prediction of the new design and/or the mean-time-between-failure (MTBF).

A mechanical stop for a moving body that minimizes bounce of the moving body after the body has hit the stop. The mechanical stop includes a flat plate having a plurality of generally triangular sectors defined by radial slits. The slits or triangular sectors prevent excessively large diaphragm stresses in the material of the plate and also reflect the flexural waves in the plate in such a way that the waves have difficulty returning to the contact area where the moving body has hit the stop and are maximally dissipated by internal friction of the plate. The mechanical stop may include a lever between the moving body and the flat plate to change the effective mass of the moving body, a spring to mediate the impact of the moving body, a relatively rigid support for the lever to minimize moments produced in a base for the flat plate, and straight line plate supports for some or all of the sectors of the flat plate to provide desirable reflections for the flexural waves in the plate.

A paint transfer article useful in forming a protective or colored coating on a compound structural component. The paint transfer article comprises an optional carrier liner sequentially covered with continuous layers of a colored layer having a colored base layer and an optional clear coating, a reinforcing layer, and an optional heat-activatable adhesive. The reinforcing layer has a sufficiently low glass transition temperature and a sufficiently high tensile modulus to resist damage to itself and the colored layer upon impact or under moderate pressure. Also a method of paint transfer using the article, a method of preparing the composite, a cold-formable painted metal bank, and a method for cold-forming painted parts.
