Title: Method and apparatus for satellite positioning system (sps) time measurement
Inventor: KRASNER NORMAN
IPC: G04G99/00
Filed: 2000-03-22
Abstract: A method and apparatus for measuring time related to satellite data messages  which are used with satellite positioning systems (SPS). In one method, a first record of at least a portion of a satellite data message is received a t an entity, which is typically a basestation. The first record is compared wi th a second record of the satellite data message, where the first record and th e second record overlap at least partially in time. Then a time is determined from this comparison, and this time indicates when the first record (or the source from which the first record was obtained) was received at a remote entity which is typically a mobile SPS receiver. Various other methods of th e invention are described and various apparatuses of the invention are also described. The methods and apparatuses measure time of day using SPS signals  without reading the satellite data messages which are transmitted as data within these signals. The methods and apparatuses are suitable for situation s in which the received signal level is too weak to allow reading of the satellite data messages.

Abstract: This invention is the constructive elements, preliminary formed in a shape of the two mainly similar stencils I and II on the surface of the two thin sheet metallic blanks. The said stencils I and II are preliminary superimposed one on another in order to be shifted for a winding outline width along the stent longitudinal axis and to form the alternating winding outlines pairs. One pair of the said winding outlines is executed by a simple superimposing of the stencil I winding outline (12) on the stencil II winding outline (14), whereas the said winding outlines pair, neighboring to it, is performed by the superimposing of the stencil II winding outline (15) on the stencil I winding outline (13). The stencil II winding outlines are passed through the slots between the stencil I winding outlines as to make the formed semicircles be located in turns in the stent expanded shape.

Patent CA-2374200-A1 (CA)
Title: Flexible stent
Inventor: BURGERMEISTER ROBERT
IPC: A61F2/06
Filed: 2002-03-01
Abstract: A preferred embodiment of a stent provides a folded strut section that provides both structural rigidity and reduction in foreshortening of the stent mechanism. A flexible section provides flexibility for delivery of the stent mechanism. In a second embodiment, flexible section columns are angled with respect to each other, and to the longitudinal axis of the stent. These relatively flexible sections are oppositely phased in order to negate any torsion along their length. In yet another embodiment, the flexible connector can take on an undulating shape (like an "N"), but such that the longitudinal axis of the connector is not parallel with the longitudinal axis of the stent. Finally, a new method is disclosed for making stents. The method consists of performing a standard photochemical machining process of cutting, cleaning and coating the tube with a photoresist. However, unlike former methods, the photoresist image is developed on the surface of the cylindrical metallic tube, which results in a controlled variable etching rate at selected sites on the cylindrical metallic tube during the etching process. Further embodiments provide living hinge connectors and connections along the length of the radial strut member.
