Abstract: A luminal graft endoprosthesis or endovascular graft is described which is capable of dilation and support functions and is suitable for the endoluminal repair of vascular lesions and the like.  An expandable support or stent is combined with a tubular graft made of a material having two unstressed conditions to provide a combined stent-graft wherein the graft material is secured to either or both of the internal and external surfaces of the stent.  The stent-graft may be positioned within a blood vessel of a living patient by an expandable balloon catheter.  The graft member is made from a biocompatible material which, when expanded, exceeds its yield point and becomes dimensionally stable without retaining significant residual forces which may cause the stent to collapse after its placement within a blood vessel.

Abstract: A digital video signal processing system receives encoded packets of data representing video image information in compressed form. A video decoder (1509) and an associated video RAM (1513) are used to decode and decompress the video packets to form groups of video image representative digital words.  The video image groups are organized in a compressed component format (e.g., Y, U, V in the ratio 4:2:2) related to the video image compression format in which pairs of color related components (U, V) correspond to more than one pixel. The video decoder (1509) also includes an on-screen display (OSD) unit (1509-9) which converts a graphics bit map stored in a section (1513-3) of the video RAM (1513) to groups of graphic image representative digital words. The graphic image groups are organized in an uncompressed component format (Y, U, V in the ratio 4:4:4). Color related components (U, V) of the uncompressed graphic image groups are deleted by a converter so as to form new graphic image groups having the same format as the video image groups which may be readily multiplexed with the video image groups to insert a graphics image within a video image.

Granted: 2005-08-23
Abstract: A multifrequency acoustic transducer with a wide band around each resonant frequency is disclosed. A .lambda./4-resonant back film (202) is inserted between a .lambda./2 active transmitting film (201) and the soft reflector (203) on which it is supported, and two adaptive films (204, 205) with impedances intended to optimise matching of the two frequencies obtained by inserting said back film are placed on said active plate. Thicknesses of said match plates are optimised using a model such as a Mason model on the basis of a value adjacent to .lambda./4 for the frequency to be matched. Sonar transducers useful both for sensing and for classification may thus be achieved.

Abstract: In accordance with the present invention, there is provided a catheter having an elongated tubular body with a distal end, a proximal end and at least one lumen extending therebetween. The body is made from three layers of extruded plastic which adhere to each other.  The body has an inner and outer layer made from a polymer, and a middle layer also made from a polymer. The middle layer is more flexible and has a lower melt temperature than the inner and outer layers. The catheter further includes an integral fuseless distal tip. The distal tip is made from the middle layer and no more than one of the inner and outer layers. The distal tip is softer than portions of the body proximal thereto. In accordance with another aspect of the present invention, there is provided a method of making a fuseless soft tip tubular catheter, of the type described above. The method involves extruding the catheter so as to form the tubular body having the inner, outer and middle layers. Thereafter, at least the distal end of the catheter is heated so as to form a distal tip. The distal tip is made from the middle layer and no more than one of the inner and outer layers. The distal tip is softer than portions of said body proximal thereto.

Abstract: There is disclosed a water-reducible, chromium-free coating composition for providing corrosion protection to a substrate, such as a metal substrate. The deposited coating film is corrosion-resistant and for coated articles which are threaded, e.g., steel fasteners, the coating provides a non-thread-filling coating. The coating composition contains particulate metal, such as particulate zinc or aluminum. Although substituents can be separately packaged, the composition is virtually always a one-package coating composition. The composition contains water-reducible organofunctional silane, particularly an epoxy functional silane, as a binding agent. The composition has highly desirable, extended shelf life. The composition can be easily applied in the usual manner, such as dip-drain or dip-spin technique, and readily cures at elevated temperature.

Abstract: A pallet and system for transporting armatures along an armature manufacturing line, where the armatures may change in configuration at different stations of the manufacturing line, accommodates the various configurations without requiring a change of pallets at a station at which a configuration change occurs. The pallet has multiple sets of seats, each set corresponding to one of the configurations that the armature may assume during processing. Whenever the configuration of the armature changes from a first configuration to a second configuration, the armature, having been removed from a set of seats that accommodates the first configuration, is replaced in a set of seats accommodating the second configuration.      One way of accomplishing the transfer is, after lifting the armature from the first set of seats, allowing the pallet to advance by the distance separating the first and second sets of seats. The armature can then be lowered directly into the second set of seats without the need for lateral movement.
