Title: Image watermarking using multiple watermarking methods for multiple regions
Inventor: PLANITZ BIRGIT MARIA
IPC: G06T1/00
Filed: 2006-07-04
Abstract: A method (100) of watermarking an image (101) is disclosed. The method (100) segments the image (101) into regions. Each region is then characterised based upon one or more statistical features of the respective regions. For each region, a watermarking method and a number of bits to be embedded into the respective region are selected based on the characterization of the region.  The number of bits of data is then embedded into the respective region using the watermarking method selected for that region. A method (105) of decoding a watermarked image (145) is also disclosed.

Abstract: The invention proposes utilizing the known geometry of the measurements in order to assign them to one another and to resolve ambiguities, wherein the 3D  position of an object (3) in space is determined by a spatial section at the same time. This is done using a plurality (N) of sensors (A, B, C) and their geometries (10, 11, 12), wherein a first sensor (A) is part of the master sensor and a space curve (A1) is calculated and then transmitted to the geometry (11) of a sensor (B) which is defined as a slave sensor and whose local geometry (11) is taken into account, a further sensor (C) is then defined as a slave in which the space curves (B1 - B3) of the correspondence obtained in the preceding step are calculated and transmitted to the geometry (12) of the new slave sensor (C) together with the master curve (A1), wherein the steps are repeated at least until the last (N) remaining sensor is defined as a slave in a last step (N-1) and the master (A1) and all of its associated measurements of the previous slave sensors (B, C) are transmitted to the local geometry of the last (N) slave sensor and compared with the measurements.

Patent CA-2634578-A1 (CA)
Inventor: RICHIE AARON
IPC: F16C32/06
Filed: 2006-12-14
Abstract: A thrust bearing assembly including a flexible thrust washer sandwiched between first and second races. The thrust washer includes notches between adjacent support regions. When a thrust load is applied to the bearing assembly, the thrust washer elastically flexes at the notched or unsupported regions and creates undulations in the washer's dynamic surface to create an initial hydrodynamic fluid wedge with respect to the corresponding dynamic surface of the second race. The gradually converging geometry created by these undulations promotes a strong hydrodynamic action that wedges a lubricant film of a predictable magnitude into the dynamic interface between the thrust washer and the second race in response to relative rotation. This lubricant film physically separates the dynamic surfaces of the thrust washer and second race from each other, thus minimizing asperity contact, and reducing friction, wear and bearing-generated heat, while permitting operation at higher load and speed combinations.

Inventor: CULLY EDWARD H
IPC: A61F2/06
Filed: 2007-04-13
Abstract: An improved stent-graft device is provided that delivers a smooth flow surface over a range of operative expanded diameters by applying a unique cover material to the stent through a technique that allows the cover to become wrinkle-free prior to reaching fully deployed diameter. The unique cover material then allows the device to continue to expand to a fully deployed diameter while maintaining a smooth and coherent flow surface throughout this additional expansion. Employed with a self- expanding device, when the device is unconstrained from a compacted diameter it will self-expand up to a fully deployed diameter with the graft being substantially wrinkle-free over diameters ranging from about 30-50% to 100% of the fully deployed diameter.

Title: Real-time location systems and methods
Inventor: MALARKY ALASTAIR
IPC: G01S5/06
Filed: 2009-02-05
Abstract: A real-time location system for identifying and locating tagged items. The system may include an identification protocol that tracks in-network transponders and assigns dynamic in-network identification numbers to in-network transponders. The system includes a locator function that employs time-of-arrival analysis. Rather than attempt to synchronize the time base at each reader, the system and process eliminate the need to sync the readers and also eliminate the impact of differential receive delays in the respective readers. Both the transponder and a master reader transmit locate signals, which are measured at slave readers. The system relies on differences in time-of-arrival of the two signals at the respective slave readers to determine the likely location of the transponder.
