Patent CA-2254139-A1 (CA)
Inventor: MUHLHAUSER NICHOLAS L
IPC: H01Q5/45
Filed: 1998-11-13
Abstract: A bifocal lens for use in a multiple beam antenna system including a reflector that is at least partially parabolic in one dimension and a pair of waveguides.      Multiple received beams are received and reflected by the reflector into an orthogonal mode junction which separates signals of a first polarity from signals of a second orthogonal polarity. The signals of the first polarity are forwarded into a first waveguide and the orthogonal signals of the second polarity are forwarded into a second parallel waveguide. A plurality of satellites may be accessed simultaneously thus allowing the user to utilize both signals at the same time. The bifocal lenses may be located in the waveguides, respectively, with each lens including a step portion defined in at least one edge thereof for matching purposes.

Abstract: Le bruit généré dans un système informatique dans une carte (100) adaptateur de modem est supprimé efficacement par aménagement d'une extension dans un plan (212) de référence de tension. Le plan de référence d'extension est couplé au plan de référence de tension de la carte adaptateur par un circuit d'impédance (350, 352). Le plan de référence d'extension fait que la carte adaptateur présente un plan de référence composite présentant une longueur globale supérieure à un quart de la longueur d'onde du signal à supprimer, de sorte que le plan de référence composite ne résonne pas à la fréquence du signal ayant généré le bruit. Les plans de référence sont de préférence connectés par un circuit résonnant de sorte que les deux plans de référence sont connectés électriquement efficacement à des hautes fréquences et sont déconnectés électriquement à des fréquences basses de sorte que la résonnance des cartes est également supprimée à des basses fréquences.

Abstract: A storage unit for compact disks that is associated with the outer shell of a computer (hereinafter referred to as a chassis), which it wraps around like a "horse and saddle" assembly. The storage unit, like a saddle, consist of two separate pouches (7), each pouch has small pockets or compartments which conform to the size of any CD. When the storage unit is mounted on the computer chassis the two pouches lay flat against the broad sides of any tower style computer chassis figure 3 (tower style chassis are now the most popular computer cases). To keep each pouch of the storage unit firmly secured to each side of the chassis, two pieces of hard narrow rods (10) are placed in the top and bottom edges of each pouch of the storage unit figure 4. These rods will act like the backbones of the invention. The storage unit will be capable of displaying a plurality of CDs and their artwork when they are placed in the storage unit. In essence the storage unit uses the huge surface area of the sides of the computer chassis, which is otherwise not utilized by any present storage cases. Most of the storage unit can be made from any soft non-scratch material. Each pouch is created by placing one after the other, designed segments (1a), (1b), (1c) and (1d) atop each other in an alternate manner starting with (1a) figure 4 which will create the compartments as seen in figure 5.

Title: System for automated generation of media programs from a database of media elements
Inventor: MARCUS DWIGHT
IPC: G06F17/30
Filed: 1998-04-01
Abstract: A system and method for creating audiovisual programming has media elements, such as audiovisual clips, stored in a library. A database contains selected information about each of the media elements. The stored information in the database does not dictate the temporal sequence of the media elements. Media elements are selected in response to a request for media programming, and arranged in a temporal organization. A user does not select the individual media elements or their temporal organization. Transitions between audiovisual clips are determined by the system based on information stored in the database and predetermined preferences as to types of transitions. Transition information includes a variety of possible transition points in an individual clip, capable of selection by the system. Separate transitions for the audio and video portions of audiovisual clips may be provided. For unique media programming, a unique sequence of cues may be included within the program for use in verification of viewing and comprehension. Upon completion of the selection of the media elements, the sequence, and the transitions, the media elements are assembled into a media program, such as a videotape.
