Patent CA-2298936-A1 (CA)
Inventor: ROLLENDER DOUGLAS HAROLD
IPC: H04M1/725
Filed: 2000-02-17
Abstract: The method for transferring data sends the data as part of first and second permanent identifiers during a communication procedure prior to establishing a traffic channel in the communication system. Besides the data, the first permanent identifier includes routing information to a home system forming part of the communication system. The second permanent identifier is an expanded permanent identifier with the data forming at least part of the expanded portion thereof. Based at least on recognizing a portion of the second permanent identifier, a home system sends the first and second permanent identifiers to a destination entity. The destination entity extracts the data from the first and second permanent identifiers. In this manner, a traffic channel does not need to be established to transmit the data.

Title: Anti-flash wick sustainer and pedestal
Inventor: PAPPAS GEORGE G
IPC: F21V37/00
Filed: 1997-11-24
Abstract: An anti-flash wick (18) support (16) for candles having a candle floor. A candle floor includes the bottom surface of a container (12) and the lowest extremity of a freestanding candle. A wick sustainer (2) having a central bore (20) is adhered to the candle floor by an adhesive plug (24) which plugs the bore near the base (19) of the upright column of the wick sustainer. The wick extends downwardly into the bore and the adhesive plug (24) prevents fuel from being drawn upwardly by the wick (18) through the bore to a flame. The flame goes out once the fuel, such as molten wax (14) descends below the top end (17) of the wick sustainer. In an alternative embodiment, a pedestal (40) extends upwardly from, and attaches to, the container floor (42). A wick sustainer (48) rests upon the fuel impervious top surface (46) of the pedestal.

Title: Storage management system for document image database
Inventor: LOPRESTI DANIEL P
IPC: H04N1/41
Filed: 1998-09-29
Abstract: A method of managing storage in a document image database (14) using document analysis (32) to partition documents into logical regions and modified by reducing storage size of the regions using different reduction modifiers according to various storage preference rules (78). Storage preference rules are intended to maintain high quality representations of important document information while reducing storage requirements at the expense of lesser important aspects of the document. In particular, the different reduction modifiers (34) applied to stored document images include reducing sampling depth, reducing sampling resolution based on minimum font size, utilizing lossy and lossless compression schemes and discarding unimportant regions of document image. Over time, document analysis and modification can be repeated to further reduce the storage size of previously stored data files (50, 52, 54).

Title: Protective athletic pads for joint surfaces
Inventor: PRATT MICHAEL K
IPC: A41D13/06
Filed: 2000-08-24
Abstract: A protective pad for a joint surface of a wearer's limb during athletic activity such as skating and skateboarding has a cushioning element and a shielding element mounted thereto. The cushioning element has a body with a first surface to overlie the joint surface and an opposite second surface. The shielding element has a primary wall forming a domed central region surrounded by a peripheral flange engaged upon the second surface of the cushioning body. In the central region, the primary wall defines an outer, obstruction-engaging surface and an inner wall surface. The shielding element also has a plurality of inter-engaged support wall segments extending from the inner wall surface toward, but spaced from engagement with, the second surface of the cushioning body. The shielding and cushioning elements, in a central region of the cushioning body bounded by the peripheral flange and overlying the joint surface, together define, at rest, a cavity between the support wall segments and the second surface of the cushioning body. The shielding element is relatively more resistant to flexing than the cushioning element, and upon application of a force to the obstruction-engaging surface of the protective pad overlying the joint surface to be protected, the shielding element resists flexing as the cushioning element flexes to permit penetration of the joint surface into the cavity, thus to absorb force and protect the joint surface.

Abstract: Procédé de mesure du profil d'un faisceau d'électrons dans un dispositif d'affichage électronique (16), selon lequel une matrice de points vidéo (24) est affichée sur un écran d'affichage du dispositif d'affichage électronique, chacun des points vidéo étant constitué d'un groupe (27) de luminophores (28) illuminés par un faisceau d'électrons. Une image d'une pluralité de groupes de luminophores illuminés formant les points vidéo dans un champ de vision est ensuite prise. Les distances moyennes horizontales et verticales des points vidéo dans le champ de vision sont déterminées et les groupes de luminophores illuminés formant les points vidéo dans le champ de vision qui sont saisis dans l'image sont superposés sur la base des distances moyennes horizontales et verticales des points vidéo, généralement pour établir la moyenne des discontinuités entre les luminophores dans les groupes et remplir lesdites discontinuités, et donc produire une image en surimpression (40) du faisceau électronique. Des sections transversales de l'image en surimpression peuvent être approximées et au moins un profil d'intensité du faisceau d'électrons peut être calculé. Des images en surimpression (40) de chaque faisceau d'électrons de couleur peuvent également être saisies simultanément, ce qui permet le calcul d'une erreur de convergence.

Title: Pipelined fast fourier transform processor
Inventor: HELLBERG RICHARD BIRGER
IPC: G06F17/14
Filed: 1998-12-18
Abstract: A fast Fourier transform (FFT) processor is constructed using discrete Fourier transform (DFT) butterfly modules having, in preferred example embodiments, sizes greater than 4. In a first example embodiment, the FFT processor employs size-8 butterflies. In a second example embodiment, the FFT processor employs size-16 butterflies. In addition, low power, fixed coefficient multipliers are employed to perform nontrivial twiddle factor multiplications in each butterfly module. The number of different, nontrivial twiddle factor multipliers is reduced by separating trivial and nontrivial twiddle factors and by taking advantage of twiddle factor symmetries in the complex plane and/or twiddle factor decomposition. In accordance with these and other factors, the present invention permits construction of an FFT processor with minimal power and IC chip surface area consumption.

Filed: 1999-04-14
Abstract: In the first embodiment, a coupling assembly (10) is provided wherein the inner peripheral diameter of an annular spring (44) is sized to be threadably received over the threads of a coupler and is held in a recess formed by the ends of threads and the edge of a shoulder. This structure minimizes the diameter of the annular spring and lock ring (43) to minimize both the size and weight of coupling assembly. Additionally, it provides a quick connect, quick disconnect coupling and has a peripheral stripe to provide a visual indication of its connected or disconnected status. In the second embodiment, a wavy spring (108) is split which allows its diameter to be temporarily enlarged so that it can be received over the threads of the coupler and then spring back to its original smaller diameter so that it is held in a recess formed by the ends of the threads and a coupler flange. This structure also minimizes the diameter of the annular spring and lock ring to minimize both the size and weight of coupling assembly. This structure also provides a quick connect, quick disconnect coupling and has an indicator stripe to identify whether or not the coupler is in locked position.
