Abstract: A method for improving the radial enlargeability and other properties of tape-reinforced tubular vascular graft formed of sintered fluoropolymer(s), such as expanded, sintered PTFE. Broadly, the method comprises the step of radially shrinking the reinforcement tape layer of the graft, or the entire tape-reinforced graft, after sintering thereof. Such radial shrinkage of the reinforcement tape layer, or of the entire graft, renders the graft subsequently radially enlargeable by more than 5%, without tearing or breaking of the reinforcement tape layer of the graft. Radially enlargeable grafts of the present invention may be combined with various types of stents or anchoring systems, to form endovascular graft devices which are transluminally insertable and implantable within the lumen of a host blood vessel. Alternatively, radially enlargeable grafts of the present invention may be implanted by way of traditional surgical graft implantation techniques, without any radial enlargement of the graft at the time of implantation, so as to take advantage of the improved strength properties and suture-holding properties of the radially-shrunken tape-reinforced grafts of the present invention.

Title: View offset estimation for stereoscopic video coding
Inventor: CHEN XUEMIN
IPC: H04N13/239
Filed: 1998-11-03
Granted: 2005-09-27
Abstract: In a stereoscopic video transmission system, where an enhancement layer image is disparity predicted using a lower layer images, the lower layer image is made to more closely match the enhancement layer image by shifting the lower layer image to the right to compensate for inter-ocular camera lens separation. The motion vector search range for disparity prediction is reduced to improve coding efficiency. At an encoder, the optimal offset, x, between the enhancement layer image and the lower layer image is determined according to either a minimum mean error or a minimum mean squared error between the enhancement and lower layer images. The offset x is bounded by an offset search range X. The x rightmost pixel columns of the lower layer image are deleted, and the x leftmost columns of the lower layer image are padded to effectively shift the lower layer image to the right by x pixels to obtain the reference image for use in disparity predicting the enhancement layer image. For arbitrarily shaped images such as VOPs within a frame, the leftmost portion is deleted and the rightmost portion is padded. At a decoder, the offset value x is recovered if available and used to reconstruct the reference frame.

Abstract: The log-periodic dipole antenna presents these problems. If the dipoles are supported by two parallel feeder conductors, those conductors are above ground potential and should not be connected to the mast for lightning protection. The feeder conductors also must be strong and, therefore heavy, because they support the dipoles. One tactic to solve these problems is to connect the dipoles to the boom through strong insulators and to feed them by a pair of crossing wires. Not only do the crossing wires not have a constant characteristic impedance, as the feeder conductors should have, this tactic also does not ground the antenna for lightning protection. These problems can be solved by using folded dipoles that have feeding points on opposite sides of the main conductors. This allows straight, small, feeder conductors, no strong insulators, and direct current paths from all conductors to the grounded mast.

Granted: 2006-12-05
Abstract: A method of reducing uncontrolled flow of a molten polymer during the packing and cooling stage of an injection molding cycle. A plurality of polymers are injected between a mold cavity and core for making a multilayer plastic article such as a preform, having an exterior layer of a first polymer and a n interior layer of a second polymer. In a tapered region of the mold, a minim um width of the tapered region is selected to prevent the second polymer from developing an enhanced leading/trailing edge effect which causes the second polymer to reverse flow during the packing and cooling stage. The method is particularly useful for making preforms for blow molded containers, such as a ketchup container, having a relatively long and thin neck profile. In addition, the method maintains the interior (barrier) layer a minimum distance from th e top sealing surface of the preform, in order to prevent defective heat-bonde d seals.

Abstract: The invention is a biological process for purifying waste water in order to produce an effluent with a low content of carbon and of oxygenated nitrogen compounds. The process includes an initial step of mixing the waste water in a biological reactor with activated sludge to denitrify the resulting mixture. Then, air is introduced into the mixture to form an anoxic sludge thereby directly oxidizing carbon present in the anoxic sludge and removing carbon therefrom, simultaneous with the denitrification. The anoxic sludge is clarified to separate it from a denitrified intermediate effluent. The clarified anoxic sludge is recycled to the biological reactor. Then, intermediate effluent is nitrified to form a nitrified liquor and a portion of the nitrified liquor is recycled into the anoxic sludge that is present in the biological reactor, thereby subjecting the anoxic sludge to oxygen present in nitrified compounds and consequently further removing carbon from the anoxic sludge, simultaneous with the denitrification. The rate of removal of carbon is controlled as a function of the flow rate/pollution characteristics of the anoxic sludge while a redox potential of the anoxic sludge is continuously measured. A nitrate concentration of the intermediate effluent is continuously measured. There is an adjustment of an amount of air introduced into the anoxic sludge in accordance with the measured redox potential and measured nitrate concentration. A recycling flow rate of the nitrified liquor is adjusted in accordance with the measured redox potential and measured nitrate concentration. The remaining nitrified liquor is the final effluent.
