Title: Prosthetic knee joint with enhanced posterior stabilization and dislocation prevention features
Inventor: PAPPAS MICHAEL J
IPC: A61F2/38
Filed: 1998-11-16
Granted: 2003-11-25
Abstract: The prosthetic knee joint is provided for resisting valgus-varus movements.  The joint includes a femoral component having a superior bone engaging surface and an inferior bearing surface.  A posterior notch extends anteriorly into the posterior end of the femoral component.  The prosthetic knee joint further includes a tibial component having an inferior bone engaging surface and a superior bearing surface.  A plastic bearing is disposed between the femoral and tibial components.  An inferior surface of the plastic bearing is in bearing engagement with the superior surface of the tibial component.  A superior bearing surface of the plastic bearing is in articular bearing engagement with the bearing surface of the femoral component.  The bearing includes a post projecting proximally from the superior surface.          The post is slidably received in the posterior notch of the femoral component and resists valgus-varus moments imposed upon the joint.          The post may include medial and lateral cam projections spaced from the superior bearing surface of the bearing.  The femoral component may include flanges at the posterior notch for engagement between the cam projections and the superior bearing surface to substantially prevent dislocation.

Abstract: A method of managing storage in a document image database (14) using document analysis (32) to partition documents into logical regions and modified by reducing storage size of the regions using different reduction modifiers according to various storage preference rules (78). Storage preference rules are intended to maintain high quality representations of important document information while reducing storage requirements at the expense of lesser important aspects of the document. In particular, the different reduction modifiers (34) applied to stored document images include reducing sampling depth, reducing sampling resolution based on minimum font size, utilizing lossy and lossless compression schemes and discarding unimportant regions of document image. Over time, document analysis and modification can be repeated to further reduce the storage size of previously stored data files (50, 52, 54).

Abstract: Multiple layer fuser belts having a woven fabric layer and a high conformability, low surface energy elastic layer. The fabric layer is formed from high modulus, high temperature fibers that are woven together at acute angles to the circumference of the belt fibers. The fabric layer forms a substrate with preferential stretching along the circumference of the fuser belt. The elastic layer is bonded to the fabric layer and is made from a highly conformable, low durometer material having a low surface tension. When the fuser belt is partially wrapped around a driven roller so as to form a nip with a pressure roller the fuser belt stretches in the direction of belt motion. As the fuser belt passes through the nip the fuser belt contracts, releasing surface tension and thus reduces sticking between the fuser belt and fused toner.

Abstract: The invention provides a method of treating diabetes in a subject, comprising administering to the diabetic subject an immunotoxin, thereby reducing the subject's T-cell population, and administering to the subject pancreatic islet cells from a donor. The immune tolerance inducing treatment regimen, used optionally with adjunct immunosuppressive agents, prevents pancreatic islet cell rejection while maintaining long term islet cell function following xenogeneic and allogeneic pancreatic islet cell transplantation. Thus, the methods of the present invention provide a means for treating diabetes, wherein the need for exogenous insulin or immunosuppressive agents is decreased or eliminated. Also provided is a method of inhibiting a rejection response of a transplant recipient, comprising administering an immunotoxin during the peritransplant period, thereby transiently reducing the number of T-cell lymphocytes and promoting long-term survival of the transplant.
