摘要： A method of producing an improved polyethylene, especially an ultra-high molecular weight polyethylene utilizes a sequential irradiation and annealing process to form a highly cross-linked polyethylene material. The use of sequential irradiation followed by sequential annealing after each irradiation allows each dose of irradiation in the series of doses to be relatively low while achieving a total dose which is sufficiently high to cross-link the material. The process may either be applied to a preformed material such as a rod or bar or sheet made from polyethylene resin or may be applied to a finished polyethylene part. If applied to a finished polyethylene part, the irradiation and annealing must be accomplished with the polyethylene material not in contact with oxygen at a concentration greater than 1% oxygen volume by volume. When applied to a preform, such as a rod, the annealing of the bulk polymer part of the rod from which the finished part is made must take place on the rod before the implant is machined therefrom and exposed to oxygen.

摘要： A method for manufacturing of ultrahigh molecular weight polyethylene (UHMWPE) for implants, where the implants have been machined out of UHMWPE blocks or extruded rods, has anthocyanin dispersely imbedded in the polyethylene. The implant is then exposed to γ ray or electron beam irradiation in an amount of at least 2.5 Mrad followed by a heat treatment to prevent the implant from becoming brittle in the long term as well as to improve strength and wear. The method includes mixing a powder or granulate resin of UHMWPE with an aqueous liquid that contains anthocyanin in a predetermined amount. The water is then evaporated in order to deposit the anthocyanin in a predetermined concentration on the polyethylene particles. The doped UHMWPE particles are compressed into blocks at temperatures in a range of approximately 135° C.-250° C. and pressures in a range of approximately 2-70 MPa. Medical implants are made from the blocks.

摘要： A processor using a first Kalman filter estimates a host vehicle state from speed and yaw rate, the latter of which may be from a yaw rate sensor if speed is greater than a threshold, and, if less, from a steer angle sensor and speed. Road curvature parameters are estimated from a curve fit of a host vehicle trajectory or from a second Kalman filter for which a state variable may be responsive to a plurality of host state variables. Kalman filters may incorporate adaptive sliding windows. Curvature of a most likely road type is estimated with an interacting multiple model (IMM) algorithm using models of different road types. A road curvature fusion subsystem provides for fusing road curvature estimates from a plurality of curvature estimators using either host vehicle state, a map database responsive to vehicle location, or measurements of a target vehicle with a radar system.

摘要： A method for encoding images according to object shapes is provided. The method enables reduced usage of storage space when an image encoding system encodes a received image frame. The method uses a bottom-up and sequential approach for encoding coefficients. The coefficients in each subband are numbered using a tree structure, wherein level N subband is designated as a root of the whole tree, level (N−1) subbands are designated as roots of subtrees, and level (N=1) subbands are designated as terminal nodes of subtrees. The terminal nodes for one of the subtrees are numbered first, and then this subtree is numbered in the bottom-up sequence. After that, the terminal nodes for another substree are numbered, and this numbering sequence continues to number all the other subtrees until the root of the tree has been numbered, so as to allow a bottom-up encoding process for the coefficient to be performed.

摘要： A method for producing a wear resistant polyethylene medical implant includes forming a medical implant, such as an orthopedic implant, made at least partially of ultra high molecular weight polyethylene (UHMWPE). The polyethylene may be irradiated with gamma ray or e-beam radiation to form free radicals and then crosslinked to eliminate free radicals prior to exposure to oxygen. The so treated bearing surface of the crosslinked polyethylene is then coated with a photoinitiator. Thereafter the bearing material is photocrosslinked with ultra-violet (UV) radiation. The photocrosslinking process can also be applied to non-crosslink UHMWPE.
