Patent number: 7281757Abstract: A process for spot-welding hydroformed members allows at least one hydroformed member to be positioned with an end butted against a lateral side of the second hydroformed member. A structural shell member sandwiches the joint around the two hydroformed members to provide a surface to which each of the hydroformed members can be spot-welded. The U-shaped structural support receives the lateral side of one hydroformed member in the bight portion thereof and has arms that are positioned against the perpendicularly positioned second hydroformed member. Each of the hydroformed members are formed with access openings therein to allow spot-welding electrodes to be positioned against an appropriate wall of the hydroformed member and the adjacent portion of the U-shaped structural shell member. The joint is rigidly formed by spot-welding each of the hydroformed members to the structural support. The process is particularly adapted for utilization in the manufacture of automotive frames.Type: GrantFiled: October 29, 2004Date of Patent: October 16, 2007Assignee: Ford Global Technologies, LLCInventors: Larry Dupuis, Dragan Stojkovic

Patent number: 7281799Abstract: A corneal topography slit image alignment system 10, includes a half-slit projector 14 for projecting half-slit images onto a patient's eye 16. Half-slit images 28 and 30 are aligned into a single slit image. A camera 18 captures an image of the aligned slit image. Processor 20 including a memory 26 connected to the half-slit projector 12 and the camera 18 analyzes the alignment of the half-slit images 28 and 30. An edge detector 22 detects the edges of each captured half-slit image and determines an amount of misalignment of the half-slit images 28 and 30 relative to half-slit images being aligned into a single slit image. This amount of misalignment allows computer processor 20 to correct the three-dimensional coordinates of the slit images obtained by a slit beam system 14.Type: GrantFiled: July 21, 2005Date of Patent: October 16, 2007Assignee: Bausch & Lomb IncorporatedInventor: Lloyd Allred

Patent number: 7281801Abstract: A system and method are provided for measuring the thickness of a tear film layer and the heights of tear menisci around upper and lower eyelids of an eye. A plurality of images are acquired between consecutive blinks the eye using optical coherence tomography (OCT). The images depict the tear film layer and tear menisci as distinct from the cornea of the eye. In an embodiment, a plurality of reflectivity profiles from an OCT image are aligned and averaged. The difference between a first peak and a second peak of the average reflectivity profile is measured to determine the thickness of the tear film layer. The heights of the upper meniscus and the lower meniscus can also be measured from the same OCT image. In an embodiment, thickness measurements from the plurality of OCT images are combined. The measurements can be used to diagnose tear disorders, analyze treatments of dry eye and evaluate artificial tears.Type: GrantFiled: September 15, 2004Date of Patent: October 16, 2007Assignee: University of RochesterInventor: Jianhua Wang
