Title: Arrangement for preventing count-to-infinity in flooding distance vector routing protocols
Inventor: WHITE RUSSELL IVAN
IPC: H04L45/02
Filed: 2005-07-06
Granted: 2012-01-03
Abstract: Each router (22a-22g) in a network is configured for generating router advertisement messages (24a-24c) according to a flooding distance vector routing protocol. Each router (22a-22g) advertisement message (24a-24c) output according to the flooding distance vector routing protocol includes reachability information for at least one destination, and an originating router identifier (26a, 26b) indicating a router having originated the reachability information. If any router receiving the router advertisement message (24a-24c) detects a match between the originating router identifier (26a, 26b) and the corresponding assigned router identifier, the received router advertisement message (24a-24c) is disregarded during calculation of the best paths from the network. If the originating router identifier (26a, 26b) identifies another router, the router floods the received router advertisement message to other ports, and output its own router advertisement message based on the received router advertisement message and that specifies the originating router identifier from the received router advertisement message.

Title: Method and apparatus for locating short circuit faults in an integrated circuit layout
Inventor: ZAVADSKY VYACHESLAV L
IPC: G06F17/50
Filed: 2005-08-03
Granted: 2011-04-12
Abstract: The method and apparatus in accordance with the present invention determines the locations of incorrectly connected polygons in a polygon representation of an integrated circuit layout. These incorrectly connected polygons result in short circuits, which often occur for major signal busses such as power and ground. It can be time-consuming to determine the exact location of the short.  The invention includes the step of tessellating the polygon representation, including each conductive layer, into predetermined shapes such as triangles or trapezoids. Each of the triangles or trapezoids is then translated into a node for the development of a nodal network where nodes are connected directly to one another to represent shapes having edges adjacent to other shape edges.  The current capacity of each connection between adjacent nodes is then specified. Two nodes that are electrically connected to the incorrectly connected polygons are selected and used as parameters for a network flow analysis algorithm. This algorithm determines the areas of high density where high flow is dictated by the triangle or trapezoid having the lowest current capacity. The areas of high density are flagged as points where short circuits may exist. These flagged points may then be investigated to confirm whether they are short circuits.

Abstract: A radiation dosimetry apparatus and method use a scintillating optical fiber array for detecting dose levels. The scintillating optical fiber detectors generate optical energy in response to a predetermined type of radiation, and are coupled to collection optical fibers that transmit the optical energy to a photo-detector for conversion to an electrical signal. The detectors may be embedded in one or more modular, water-equivalent phantom slabs. A repeatable connector couples the collection fibers to the photo-detector, maintaining the fiber ends in a predetermined spatial relationship. The detector fibers may be distributed as desired in a three-dimensional detection space, and may be oriented with their longitudinal axes at different orientations relative to a transmission axis of an incident radiation beam.
