Method for Determining the Horizontal Profile of a Flight Plan Complying with a Prescribed Vertical Flight Profile

The present invention relates to the definition, in a flight plan, of the horizontal profile of an air route with vertical flight and speed profile prescribed on departure and / or on arrival, by a stringing together of check-points and / or turn points associated with local flight constraints and called “D-Fix” because they are not listed in a published navigation database like those called “Waypoints”. It consists in charting, on curvilinear distance maps, a direct curvilinear path joining the departure point to the destination point of the air route while complying with vertical flight and speed profiles prescribed on departure and / or on arrival and while guaranteeing a circumnavigation of the surrounding reliefs and compliance with regulated overfly zones, then in approximating the series of points of the direct curvilinear path by a sequence of straight segments complying with an arbitrary maximum deviation threshold relative to the points of the series and an arbitrary minimum lateral deviation threshold relative to the set of obstacles to be circumnavigated and in adopting as “D-Fix” points the points of the intermediate intersections of the rectilinear segments.

The energy dissipation type buckling constraint support is characterized in that the support is composed of an end constraint segment, an energy dissipation segment and a support straight segment; and the two ends are connected with beams or column components or nodes to form a whole through bolt connection so as to achieve the purpose of improving of the resistant-lateral rigidity of components. The energy dissipation type buckling constraint support with the symmetrical initial imperfection unit at the end is adopted, and thus under the action of a small earthquake, the buckling constraint support keeps elasticity; and under the action of a medium earthquake or a severe earthquake, the buckling constraint support enters a yield stage, and the effect of a damper can further be achieved through the good hysteretic energy dissipation performance of the buckling constraint support. Compared with traditional buckling constraint supports, according to a manufacturing technology of the energy dissipation type buckling constraint support, the processes of adding a sleeve outside a core energy dissipation component, grouting and the like in the traditional manufacturing process are avoided in the manufacturing technology, so that manufacturing is convenient. The energy dissipation type buckling constraint support can be prefabricated and formed in a factory, the quality of the components is ensured, the workload of site operation is reduced, and energy conservation and environment protection are achieved.

Expandable endovascular stent

InactiveUS20050080479A1Minimize amount of materialSubstantial longitudinal flexibility longitudinalStentsBlood vesselsStress concentrationPercent Diameter Stenosis
Disclosed herein is a tubular endovascular stent comprising a plurality of annular segments connected by one or more bridging elements. Each annular segment takes forms of periodic wavelets with a plurality of alternating symmetric peaks and valleys, preferably consisting of circular arc segments of large radii connected tangentially with straight segments to minimize stress concentration when the stent undergoes radial deformation, transverse to the longitudinal axis of the stent. The points of connection between the bridging elements and adjacent annular segments are so designed that deformations of the bridging elements remain negligible as the stent deforms radially, namely, the longitudinal dimension of the stent does not vary during the radial expansion or contraction of the stent. Hence, the radial strength and the longitudinal flexibility of the stent made according to the principles disclosed by the present invention can be independently controlled by the design parameters for the annular segments and bridging elements, without compromising the longitudinal dimensional stability of the stent. Since stress concentration and deformation in the stent can lead to restenosis, stent made from the invention disclosed here can reduce the probability of restenosis.

Method of making cascaded multilayer stator winding with interleaved transitions

A method for making a stator assembly includes forming several continuous conductors with generally-coplanar parallel-spaced straight segments interconnected by end loop segments, as by winding each of several conductors on a peg board, and then pressing the conductors to form either one, two, or three generally-orthogonal “jogs” in a given end loop segment. The conductors are interpositioned with their straight segments staggered and with a first leg of each subsequent conductor's end loop segments generally overlying a second leg of the immediately-prior conductor's end loop segments, except for the two end loop segments following the first conductor's “nth” straight segment, and multiples thereof, where the stacking order is reversed (“n” being equal to the number of stator core slots divided by the number of conductors that will form a given winding layer). The resulting preform is inserted into the core slots over multiple revolutions to thereby obtain a multilayer cascaded stator winding with interleaved transitions.

Reshaping freehand drawn lines and shapes in an electronic document

The invention improves the appearance of freehand drawn lines and shapes in an electronic document by first recognizing freehand drawn lines and shapes and generating a line made up of sequential straight line segments for the freehand drawn line when the line does not form a closed line and generating a multiple straight-line-segment shape when the line forms a closed line. If a multiple segment shape is being reshaped, a basic shape is selected from reference ideal shapes as the basic shape of the multiple segment shape. The basic shape is adjusted to provide a specific shape as an improved shape for the freehand drawn shape. The recognition of the freehand drawn lines and shapes is accomplished by comparing source segments of a source freehand drawn line to a straight line and substituting a straight line segment for a source segment if the deviation between the source segment and the straight line is below a predetermined value. Sequential source segments of a source freehand drawn line are evaluated to determine if they are an angle segment. A segment pair of sequential source line segments are defined as an angle segment having two straight line segments intersecting at a common end point if both source segments of the segment pair are within a predetermined deviation value from a straight line. The straight line segments and angle segments are combined to form a multiple segment line if the line does not close on itself and a multiple segment shape if the line does close on itself.
