Publication number: 20170219370Abstract: Systems and methods for identifying prominent landmarks in a geographic area are provided. More particularly, geographic imagery data, such as panoramic images captured by a camera from a perspective at or near ground level, can be analyzed to identify landmarks depicted in the geographic imagery data. For instance, structure-from-motion techniques can be used to generate a point cloud of tracked features that are located a threshold distance away from one or more camera perspectives associated with the geographic imagery data. Landmarks that are visible from multiple camera perspectives and that are visible from greater distances relative to one or more camera perspectives can be identified as prominent landmarks in a geographic area. A geographic information system can use the prominent landmarks for a variety of purposes, such as for use in providing travel directions, for rendering landmarks in an emphasized style, and/or for constructing/displaying a three-dimensional model of the landmark.Type: ApplicationFiled: April 17, 2017Publication date: August 3, 2017Inventors: Brian Edmont Brewington, Bryan M.

Publication number: 20140277368Abstract: The present invention is directed to a prosthesis and method for treating, repairing, and/or replacing an abdominal aortic aneurysm. The prosthesis includes a coiled stent comprised of shape memory material having first and second anchoring zones and an intermediate zone. The prosthesis also includes graft material engaging at least a portion of the stent. During delivery of the prosthesis, the stent is in a substantially straight longitudinal configuration, and after delivery of the prosthesis the stent is returned to a coiled configuration. The diameter of the prosthesis may be adjusted by controlling the degree to which the stent is coiled.Type: ApplicationFiled: March 12, 2013Publication date: September 18, 2014Applicant: CORDIS CORPORATIONInventors: Alfredo CASTANEDA, Donald Francis DePalma, Clifford J.

Publication number: 20140222132Abstract: An endoprosthetic device for treating abdominal aortic aneurysms using suprarenal fixation. A stent ring is anchored in an area above the renal arties using self-flaring barbs that project during the nitinol expansion process. Sutures extend from the stent ring to an area below the renal arties to a bifurcated trunk portion comprising a nitinol fabric on a non-kinking frame. The bifurcated trunk is sealed proximal the iliac arteries and includes iliac leg holders having self-flaring retention struts for non-traumatic holding of iliac leg prosthetics. Suprarenal fixation and collapsible cells having retention projections and barbs that only flare during the nitinol expansion process assist in lowering the devices profile and sheathability for percutaneous delivery and may provide for recapturing the anchored device.Type: ApplicationFiled: April 8, 2014Publication date: August 7, 2014Applicant: CORDIS CORPORATIONInventors: Donald D. Boucher, Michael Dugery, Kirk L. Johnson, Issac John Khan, David C. Majercak, Scott Rush

Patent number: 8142468Abstract: A guidewire navigable through body vessels of a human subject for delivery of a catheter or the like is provided. The guidewire includes an expandable segment movable between a collapsed state and an expanded state. If the catheter encounters resistance in a vessel and cannot be advanced further, the medical professional can move the expandable segment to the expanded state in which the expandable segment engages an inner surface of the catheter. The expandable segment locks onto the catheter, which allows the guidewire and catheter to be advanced through the vessel together as a single unit. An inflatable balloon catheter movable along the guidewire requires only a single tube and is sealed by the expandable segment of the guidewire for subsequent inflation.Type: GrantFiled: December 22, 2005Date of Patent: March 27, 2012Assignee: Cordis CorporationInventors: Mark N.

Patent number: 7401160Abstract: A system and method of routing requests received from client computers. The client computer processor is redirected to a router for which the address is within the preferred coverage zone. If a router is not identified for which the address is within a preferred coverage zone, but a router other than the router that received the request is identified for which the address is within a regular coverage zone, the processor is redirected to the router for which the address is within the regular coverage zone. If a message is transmitted from a router behind a firewall to a router outside the firewall, and then a request for data is received from a processor behind the firewall, the processor is redirected to the address of the router. Routers register themselves dynamically into a hierarchy. In another alternative embodiment, a service request from a particular client computer is serviced immediately by the root router rather than redirected to another router.Type: GrantFiled: October 18, 2005Date of Patent: July 15, 2008Assignee: Cisco Technology, Inc.Inventors: Kirk L. Johnson, M. Frans Kaashoek

Patent number: 7284220Abstract: A method of performing analytical placement of components for a circuit design can include the steps of modifying an analytical formulation for placement of the circuit design a priori (when the circuit design or programmable device fabric includes inhomogeneous components) providing a modified analytical formulation and applying the modified analytical formulation during placement of the circuit design. The step of modifying can optionally include introducing terms into the analytical formulation that push components away from locations in which they cannot reside (such as a large hole in the programmable device fabric due to a large, fixed component such as a CPU core) or alternatively or optionally the step of introducing (115) terms into the analytical formulation that pull components that can only reside at a relatively small number of locations towards those locations.Type: GrantFiled: October 15, 2004Date of Patent: October 16, 2007Assignee: Xilinx, Inc.Inventor: Kirk L. Johnson

Publication number: 20070185524Abstract: A catheterization system and method including a rapid exchange emboli capture guidewire system comprising a distal emboli protection device is disclosed. The protection device is delivered to an area of interest via a delivery sheath including a longitudinal exit configured to permit the sheath to be peeled away from the guidewire to speed its removal. A capture sheath having a side-port is used to capture and retrieve the filter after a catheterization treatment procedure in a time saving manner. A torque steering device is used to steer the device and is adapted to clamp onto the guidewire while leaving sheaths free to prevent inadvertent steering of the sheaths. Using the sheaths of the present invention also allows systems to use shorter guidewires than prior art systems, further speeding the catheterization procedures being performed.Type: ApplicationFiled: February 3, 2006Publication date: August 9, 2007Inventors: Pedro Diaz, Kirk L. Johnson

Patent number: 7201770Abstract: A stent delivery catheter includes at least an inner and outer body, and a specially shaped balloon affixed near one end of both of the inner and outer bodies. At least the outer body is tubular, and the space between the outer and inner bodies defines an inflation lumen for inflating and deflating the balloon. The balloon is designed to surround and hold a compressed self-expanding stent in a small initial size. An inner portion of the cylindrical balloon extends from where it is affixed to the inner body of the catheter shaft at a point proximal to the stent to a distal leading edge at a point distal to the stent. At this leading edge, the balloon is folded back upon itself, and an outer portion of the balloon extends proximally from the leading edge to a point proximal of the stent where it is affixed to the outer body of the catheter shaft. When the outer body is retracted in the proximal direction, the balloon progressively peels back or everts, to progressively release the stent.Type: GrantFiled: October 28, 2002Date of Patent: April 10, 2007Assignee: Cordis CorporationInventors: Kirk L.
