IPC: H04N3/27
Filed: 2000-09-06
Abstract: Quand une image ayant un facteur de forme de 16:9 est comprimée dans le sens vertical pour être affichée sur un écran d'affichage ayant un facteur de forme de 4:3, un signal à niveaux de gris est inséré dans le haut et le bas d'un signal d'image et un niveau de luminosité du signal de niveaux de gris inséré est effectué pour correspondre à un niveau de luminosité moyen du signal d'image. En outre, lorsqu'une image ayant un facteur de forme de 4:3 est compressée dans une direction horizontale pour être affichée sur un écran d'affichage ayant un facteur de forme de16:9, un signal de niveaux gris est inséré dans une bordure à droite et une bordure à gauche d'un signal d'image et un niveau de luminosité du signal de niveaux de gris inséré est effectué pour correspondre à un niveau de luminosité moyen du signal d'image. En conséquence, une ligne de démarcation entre une zone d'image vidéo et une zone d'image non vidéo en raison de la différence des caractéristiques lumineuses des phosphores devient difficilement reconnaissable.

Patent CA-2322046-A1 (CA)
Inventor: RETTEW RICHARD R
IPC: H01F27/32
Filed: 1999-10-13
Abstract: An improved low voltage winding for dry insulated transformer has its windings resin encapsulated. The winding is constructed with flexible sheet conductors wound coincident with an insulating sheet material. Insulating spacers provide a means to form air channels in the windings during the coil forming process. A sealant is applied to openings at the lower ends and along vertical seams of the coil prior to the resin impregnation and encapsulation process. This will prevent drainage of the resin during a curing cycle. The result is a coil that exhibits high short circuit protection due to the tightly bond sheet conductors which will prevent movement of the conductors during short circuit conditions and also increases the radial compressive strength of the coil.

Title: Method and system for property page management
Inventor: PROVO NATHAN JACK
IPC: H04L29/08
Filed: 2000-10-13
Abstract: A system and method for property page management utilizes a property page set document to describe a set of property pages. The property page set document is stored on a server computer and transmitted to a client computer via a communication network. The client runs a browser, or other graphical user interface, to request a property page set associated with theproperty page set document, however, the server first sends an applet object that assists the browser in handling the extensible markup language found in the property page set document. The client using the applet object then parses out and builds from the property page set document multiple property pages that are cached on the client. The client to furnish values to the property pages uses a separate data set document, also in extensible markup language, received from the server. Alternatively, values are embedded for the property pages are in the property page set document. When a user makes changes to any values of a property page, the changes are incorporated into either the property page set document or the data set document stored on the client. The client waits until the user finishes using the property page set with updated values before sending updated data set document, or alternatively, the updated property page set document to the server. Other embodiments manage types of displayable information structures other than the property pages.

Patent CA-2347425-A1 (CA)
Inventor: RAJAGOPAL PRADEEP
IPC: H01L33/34
Filed: 1999-11-23
Abstract: An underlying gallium nitride layer (104) on a silicon carbide substrate (102) patterned with a mask (109) that includes an array of openings therein, and is etched through the array of openings to define posts (106) in the underlying gallium nitride layer and trenches (107) therebetween. The posts each include a sidewall (105) and a top having the mask thereon. The sidewalls of the posts are laterally grown into the trenches to thereby form a gallium nitride semiconductor layer (108a). During this lateral growth, the mask prevents nucleation and vertical growth from the tops of the posts. Accordingly, growth proceeds laterally into the trenches, suspended from the sidewalls of the posts. The sidewalls of the posts may be laterally grown into the trenches until the laterally grown sidewalls coalesce in the trenches to thereby form a gallium nitride semiconductor layer. The lateral growth from the sidewalls of the posts may be continued so that the gallium nitride layer grows vertically through the openings in the mask and laterally overgrows onto the mask on the tops of the posts, to thereby form a gallium nitride semiconductor layer (108b). The lateral overgrowth can be continued until the grown sidewalls coalesce on the mask to thereby form a continuous gallium nitride semiconductor layer.  Microelectronic devices (110) may be formed in the continuous gallium nitride semiconductor layer.
