Abstract: A method for writing a master image on a substrate includes dividing the master image into a matrix of frames, each frame including an array of pixels defining a respective frame image in a respective frame position within the master image. An electron beam is scanned in a raster pattern over the substrate, while shaping the electron beam responsively to the respective frame image of each of the frames as the electron beam is scanned over the respective frame position, so that in each frame, the electron beam simultaneously writes a multiplicity of the pixels onto the substrate.

Abstract: Devices, systems, and methods for implanting expandable prostheses in the body lumens rely on stapling or anchoring the prostheses with separately introduced fasteners. The prostheses may be self-expanding or balloon expandable, and may include a single lumen or more than one lumen. After initial placement, a stapling system is introduced within the expanded prosthesis to deploy a plurality of fasteners to at least one prosthesis end. The stapling system may apply a force to the prosthesis to modify the shape of the prosthesis to conform to the shape of the vessel wall. The stapling system can be deflected in one or more distinct steerable segments. A lumen extension or lumens may be coupled to the prosthesis to extend the reach of the prosthesis within the implantation site. Fasteners may also be applied to the lumen extensions.

Abstract: The invention is a spark plug having multiple precise spark gaps (G} with a donut shaped electrode (20) attached to the firing end of the central electrode (32), as well as a cylindrical ground sleeve (40) that is pressed on to the primary shell (36) of the spark plug. The electrode donut (20) is generally flat and laded out in a radial direction towards the ground prongs (42) that protrude up towards the firing end from the ground sleeve (40). In conjunction with their structure, allow for the generation of a spark from every single ground prong (42) on the ground sleeve (40). This is spark potential area (G). Such multiple spark potential area along with the electrode donut (20) and ground sleeve (40) relation provides a more rapid and complete combustion of the air-fuel mixture within the internal combustion engine, which, in turn, results in more torque and more horse power.
