Patent CA-2501198-C (CA)
Title: Universal web based access functionality for remote electronic devices
Inventor: TARACI BRIAN RICHARD
IPC: H04L12/24
Filed: 2003-10-03
Granted: 2012-10-02
Abstract: A flexible electronic asset management system using Ethernet connectivity for electronic devices is presented. The invention enables multiple electronic devices (105, 107, 108, 109, 121, 117, 119) to be controlled, monitored, and accessed from any browser (104) connected to a computer network (102). A  flattened stack approach is used to process network packet data. The flattened stack approach treats the network packet as a single string of data and uses the first few bytes of information to decide whether to drop or process the incoming data thus providing for faster network traffic processing. Since the lowest layer of the OSI stack has knowledge of what applications are active in the upper layers, the flattened stack allows the packet to be discarded at the earliest possible point so no processing power is wasted. The flattened stack also organizes its check/ processing based on the raw data stream thus minimizing buffer requirements and providing for easier implementation into hardware.

Abstract: An medical device shaft (12) including an unbalanced braid reinforcement layer (32). The reinforcement layer may be an unbalanced braid by having a first set of strands (36) and a second set of strands (38), the sets wound in opposing directions on a mandrel or on the device shaft. The first set and second set may have different numbers of strands, sizes of strands, or pitch, or combinations thereof. In some embodiments, the unbalanced braid increases contact area between the inner layer and the outer layer of the shaft without compromising the function of the braid. In other embodiments, the variations in strand size and number between the first set and the second set allows improved kink and torque performance in a reduced thickness braid layer. The improved shaft of the present invention may be incorporated into a wide variety of medical devices such as guide catheters, diagnostic catheters, balloon catheters, etc.

Abstract: A vibratory material separating apparatus has at least two plateau conveying surfaces interrupted by a drop out opening. A composite mixture is conveyed by a vibrating action beyond the first conveying plateau and over a foraminous section in the first conveying plateau adjacent the drop out opening. Air is directed upwardly through the foraminous section to break apart the composite mixture, and an air supply formed by an air duct is also directed angularly in relationship to the plane of the first conveying plateau to further break apart the composite mixture and to propel particles of predetermined density and/or dimension to the landing area on the second conveying plateau. The air duct is adjustable between a first position and a second position to form an air stream having an adjustable and width. In another aspect, a separating tube is located between and spaced from the first and second conveying plateaus, within the drop out opening. The separating tube interacts with the air stream produced by the air duct to assist in carrying particles passing over the leading edge of the separating tube over the drop out opening and onto the landing area of the second conveying plateau.

Title: Computer-vision system for classification and spatial localization of bounded 3d-objects
Inventor: BALSLEV IVAR
IPC: G06V10/46
Filed: 2004-08-13
Granted: 2011-02-08
Abstract: The invention relates to a system and method for recognition, classification and spatial localisation of bounded 3D-objects. In particular it relates to a computerised method for recognition, classification and localization of objects. The method comprises generation of a training database based on a large number of training views recorded by a camera or constructed using a CAD  representation of an object. Characteristic curves are derived from the training views, and primitives of the curves are detected. Intrinsic and extrinsic descriptors of features are stored in the database together with data about the object class and pose of the view. Finally the recognition takes place in two stages: First the intrinsic descriptors of the recognition view are compared with those of the database. Second, among the best matching features it is explored which features agree mutually in the sense that they suggest the same object class at the same pose.

Abstract: A process for forming a variable gauge metal sheet into a desired shape.  The variable gauge metal sheet has a first surface and a second surface, having a thickness measured at any point on the metal sheet as the distance between the first surface and the second surface, and with the thickness of the metal sheet being different over a first portion of the sheet than over a second portion of the sheet. The process comprises forming said metal sheet into a first desired shape by bending the metal sheet about a first fold line extending through both the first portion and the second portion, to bring segments of the first surface of the metal sheet on either side of the first fold line into increased opposition with each other.  The bending of the metal sheet is effected by holding the metal sheet on a first clamped side of the first fold line secured between a first clamping die and a second clamping die while applying forces to the second surface of the metal sheet on a second moved side of the first fold line. The first clamping die has a first engagement surface which engages the first surface of the metal sheet and is a complementary mirror image to a surface contour of the first surface of the metal sheet that it engages. The second clamping die has second engagement surface which engages the second surface of the metal sheet and is a complementary mirror image to a surface contour of the second surface of the metal sheet that it engages.

Title: Post retention anchor
Inventor: KELLER WILLIAM R SR
IPC: E04H12/22
Filed: 2006-03-21
Granted: 2011-02-01
Abstract: The invention is a means for anchoring a degradation-resistant treated post or one protected with a conforming, protective cover into the ground so that it resists uplift or pull-out forces of a predetermined value without compromising the integrity of the treatment or protective cover. Anchoring is accomplished by applying indentations to the portion of the post to be embedded in the ground prior to applying the conforming, protective cover or the other material degradation-resistant treatment. The indentations on the post are configured such that the protective cover will conform to the irregularities when the protective cover is applied to the post. Indentations are applied to posts prior to application of any degradation-resistant treatments so that the integrity of the treatment is not compromised by the indentation. In the preferred embodiment, the indentations are formed on a conventional square post by milling a portion or portions of the post to create inset areas, principally at the corners, prior to applying the conforming, protective cover.

Title: Method and kit for the production of particles labelled with rhenium-188
Inventor: WUNDERLICH GERD
IPC: A61K51/08
Filed: 2005-01-27
Granted: 2010-04-06
Abstract: The invention relates to a method for the production of particles labelled with the radioactive isotope Rhenium-188 (Re-188) and a kit for carrying out said method. Such radioactively-charged particles can be used in medicine, preferably in oncology and nuclear medicine, for the radiotherapy of tumours, or metastases of tumours.  According to the method, the particles are suspended in a solution and heated, whereupon the solution firstly has a pH value of pH 1 to pH 3 and contains a tin-II salt and a Re-188 perrhenate salt. After 45 to 70 minutes of heating the pH value is increased.  The suspension obtained after increasing the pH may be directly used for radiotherapy in patients. Radiation protection of the personnel is significantly improved as a result of the unnecessary washing step, along with a corresponding saving in time.  Furthermore, the requirement of tin-II salt for the labelling is reduced and the labelling yield is increased.
