Title: Image processing device, image processing method, image processing program, and recording medium
Inventor: ONAI RIKIO
IPC: H04N1/387
Filed: 2010-10-18
Abstract: Provided are an image processing device, image processing method, image processing program, and recording medium for transforming a target image which does not have an outline comprising straight line portions. An ellipse (E1) which approximates a target image to be processed is calculated (S20). A centre candidate (OA) of the target image is determined (S21). A first polygon (P1) associated with the ellipse and the centre candidate is calculated (S22). A projective transformation matrix is calculated, in which the first polygon is projectively transformed to a second polygon (P1') associated with the ellipse centred at the point where the centre candidate is projectively transformed (S23). The target image is projectively transformed in accordance with the projective transformation matrix in order to acquire a transformation image (S24).

Title: Distributed failure recovery in a routed ethernet network
Inventor: SMITH PETER ASHWOOD
IPC: H04L69/40
Filed: 2011-03-18
Abstract: Link identifiers such as VIDs, selected from a defined range of values, are locally assigned by each node on a link state protocol controlled Ethernet network to each of its links or adjacencies. The link identifiers are assigned by the nodes such that each link or adjacency at the node is uniquely identified by a different link identifier. A link state protocol adjacency notification mechanism or other flooding mechanism is used to disseminate the locally assigned link identifiers to other nodes on the link state protocol controlled Ethernet network. The link identifiers are added by the nodes to their topology databases to enable detour routes to be locally calculated by the nodes on the network in a distributed manner. Upon occurrence of a failure, the link identifiers are used to source route traffic around the failure so that traffic may continue to traverse the link state protocol controlled Ethernet network.

Abstract: Dans la présente invention, un ou plusieurs modes de réalisation concernent une antenne hélicoïdale quadrifilaire qui peut être formée pour accepter de multiples fréquences au moyen d'un unique système d'alimentation à microruban, comprenant, à titre d'illustration, un symétriseur infini (60) en combinaison avec des conducteurs d'antenne dispersés (20, 30) qui sont syntonisés pour assurer une résonnance efficace aux fréquences souhaitées autour de l'unique système d'alimentation. Un des aspects complémentaires de l'invention combine les éléments d'antenne multifréquence et l'unique système d'alimentation en une seule pièce à géométrie cylindrique dont la taille est généralement réduite avec l'agencement dispersé des multiples conducteurs d'antenne (résonnante p. ex.) enveloppé dans une surface cylindrique courte. L'utilisation de l'unique système d'alimentation hybride et des conducteurs d'antenne résonnante multifréquence fait qu'il est moins nécessaire de recourir à des réseaux d'alimentation complexes ayant plusieurs circuits (circuits hybrides, transformateurs, etc.), tout en maintenant des niveaux de performances acceptables.

Patent CA-2813295-A1 (CA)
Inventor: CAI ZHIJUN
IPC: H04L27/26
Filed: 2010-11-30
Abstract: A methodology that enables narrowband aperiodic sounding and frequency hopping through the use of additional RRC configuration, thus requiring little or no additional Ll overhead to support narrowband frequency hopping for aperiodic sounding transmissions. More specifically, a simple approach for extending the LTE periodic sounding reference signal methodology to include aperiodic sounding. One benefit of the proposed technique is that it enables each UE to perform aperiodic channel sounding in every sounding subframe using a frequency-hopped approach where the sounding bandwidth of the UE can be narrowed appropriately to match its link capability. Additional benefits of the new approach include better resource utilization, lower signaling overhead, faster channel information update rates, and lower blocking probabilities.
