Patent CA-2401707-A1 (CA)
Inventor: CARL FREDERICK GORDON JR
IPC: E21B47/12
Filed: 2001-03-02
Abstract: A petroleum well having a communication system and a hydraulic system is provided. The petroleum well includes a borehole and a piping structure positioned within the borehole. The communication system supplies a time varying electric current downhole along the piping structure. The hydraulic system (70), which is positioned downhole proximate the piping structure (26), receives the time varying current to operate an electric motor (78). The motor drives a pump (76) which pressurizes hydraulic fluid to selectively drive an actuator (84). The actuator (84) is operably connected to a downhole device, such as a shutoff valve, and operates the downhole device as the actuator (84) is driven by the pressurized hydraulic fluid.

Title: Method and apparatus related to call centre templates for handling caller-identified network difficulties
Inventor: CROWTHER MICHAEL JOHN
IPC: H04M3/38
Filed: 2001-03-16
Abstract: A call centre associated with an intelligent network has no service-specific executable application software running on its operator positions. Instead, each computer stores a set of templates which define respective screen displays, including text display areas and text input areas, and also a set of corporate logos. When an intelligent peripheral of the network is not able to proceed with a call in accordance with an application, a failure notification is sent to the network, which reroutes, i.e.  connects, that call to the call centre and sends a message including an identifier for template to be used by an operator position in generating a screen display.  The operator interacts with the customer, obtains information and enters this in the text entry areas, sends a return message to the network, which then sends a message containing an identifier for a template to be used for the next stage of that application.

Abstract: Hard surface cleaning formulations include an associative thickener and a blend of at least two nonionic surfactants selected from the group consisting of ethoxylated alcohols and ethoxylated fatty acids. The formulations exhibit an advantageously high foam volume of at least about 150 cc when a 100 ml aqueous solution containing about 0.1 wt.% of the formulation is agitated at 2,500 rpm for a cumulative agitation period of about 1200 seconds. The formulations also exhibit satisfactory foam stability sufficient to clean at least about 25 plates (ASTM D4009-92). Preferably, the associative thickener is the reaction product of a C6 or greater epoxide compound with a polyoxyalkylene polyol.

Title: Energy controller for vibration welder
Inventor: SIMON WILLIAM P
IPC: B29C65/06
Filed: 2001-06-15
Abstract: An energy controller (36) is described for a vibration welder (10) wherein the energy imparted into work-pieces (16, 18) being vibration welded is derived and compared with an energy set point to control the vibration welding operation. After a vibration welding operation has encountered the energy set point the welding operation is stopped and the quality of a weld derived from a comparison with another parameter associated with the vibration welding. The other parameter can be the amount of movement of one of the work-pieces during vibration welding or the time involved to inject the energy into the work-pieces to achieve the vibration weld.

Title: A method and apparatus for structure-adaptive noise estimation in video signals
Inventor: AMER AISHY
IPC: H04N19/86
Filed: 2002-12-17
Abstract: Noise can be introduced into a video image in many ways and can significantly impact the effectiveness of video processing algorithms.  This paper proposes a fast automated white-noise estimation method that gives reliable estimates in video images with low and high noise levels and images with smooth and textured areas.  This technique finds homogeneous blocks and estimates the noise variance in these blocks.  It takes video image structure into account.  The method uses a new measure to determine if a block is homogeneous.  The proposed method selects intensity-homogeneous blocks in a video image by rejecting blocks with structure using a new structure analyzer.  The analyzer used is based on high-pass operators and special masks for corners to allow implicit detection of structure and to stabilize the homogeneity estimation.   For typical video quality (PSNR of 20-40 dB) the proposed method outperforms other methods significantly and the worst-case estimation error is 3 dB, which is suitable for real applications such as video surveillance or broadcasts.   The method performs well even in images with few smooth areas and in highly noisy images.

Title: Flexible over the wing passenger loading bridge
Inventor: HUTTON NEIL
IPC: B64F1/305
Filed: 2003-01-14
Abstract: Disclosed is a novel apparatus for moving passengers between an airport terminal building and a doorway of an aircraft located rearward of a wing of the aircraft. The inventive apparatus includes a passageway member pivotally anchored to one of the terminal building and a passenger loading bridge for servicing a front doorway of a same aircraft. The apparatus includes a telescopic passageway member that is pivotally mounted to the passageway member via a flexible connection. In use, the apparatus is cantilevered over the wing of an aircraft with the flexible connection substantially above a highest point along an upper surface of the aircraft wing. The flexible connection allows a cabin carried at an outboard end of the telescopic passageway member to mate to the rear doorway of the aircraft, providing an open passageway between the rear doorway and the terminal building through which passengers deplane. Positioning the flexible connection above the high point of the wing approximately minimizes the inclination of each passageway member floor surface.
