Title: Codage audio sur la base de trames avec des bancs de filtres supplementaires pour attenuer un depassement de canal spectral aux limites de trames
Inventor: FIELDER LOUIS DUNN
IPC: G10L19/02
Filed: 1998-10-15
Granted: 2005-12-20
Abstract: L'invention concerne l'utilisation de plusieurs techniques de traitement de signaux audio dans différentes combinaisons pour améliorer la qualité audio représentée par un flux de données formé par montage par collure de deux ou plusieurs autres flux de données. Ces techniques s'utilisent notamment dans des applications mettant en paquet des données audio avec des données vidéo. Dans une technique selon l'invention, on utilise des mots de commande de gain transportés avec le flux de données audio pour interpoler des niveaux sonores de reproduction à travers une collure. Dans une autre technique, on utilise des bancs de filtres spéciaux ou des formes de transformées TDCA pour supprimer des artefacts de repliement du spectre de part et d'autre de la collure. Dans une autre technique encore, on utilise des bancs de filtres spéciaux ou des fonctions de fenêtres de fondu enchaîné pour optimiser l'atténuation d'un dépassement de canal spectral créé au niveau d'une collure. Dans une autre technique, on convertit des fréquences audio échantillons en fonction de longueurs et de fréquences de trames pour permettre de mettre en paquet des données audio avec, par exemple, des données vidéo. Dans une autre technique enfin, on aligne de manière dynamique des blocs audio afin de pouvoir maintenir une synchronisation appropriée à travers une collure. On prend comme exemple une audio de 48 kHz avec une vidéo NTSC.

Title: Path search circuit for simultaneously performing antenna directivity control and path search
Inventor: SATO TOSHIFUMI
IPC: H04W16/28
Filed: 2000-07-12
Granted: 2004-10-26
Abstract: A path search circuit simultaneously performs antenna directivity control and a path search. A weighting controller controls weighting coefficients to establish an antenna directivity in a plurality of directions in which a party to communicate with is possibly present, when a communication session starts. A weighted-mean-value processor calculates delay profiles for the respective antenna directivities. A correlation peak detector detects a peak from the calculated delay profiles for thereby carrying out general antenna directivity control and a path search. At the time of starting the communication session when the direction of a mobile terminal is unknown, a path search can be conducted using a signal with a Eb/Io increased by an antenna gain for increased path search accuracy.
Patent CA-2323220-C (CA)

Granted: 2005-06-28
Abstract: A lithium secondary battery includes an electrode body obtained by winding or laminating a positive electrode and a negative electrode via a separator, and a non-aqueous electrolytic solution containing a lithium compound as the electrolyte. The non-aqueous electrolytic solution contains water (H2O) and hydrofluoric acid (HF) in a total concentration of 10,000 ppm or less. Owing to the restriction of the total concentration of water and hydrofluoric acid contained in the non-aqueous electrolytic solution, the lithium secondary battery can suppress the deterioration of battery properties caused by the water and hydrofluoric acid and has excellent cycle property and reliability.

Granted: 2006-04-11
Abstract: L'invention concerne un dispositif laser comprenant une source optique haute puissance à couplage de fibre qui comprend une diode (10) laser à grande surface présentant un revêtement à haute réflectivité sur sa facette (12) arrière, des systèmes (20) optiques de couplage, et une fibre (30) optique comprenant un réseau (32) réflecteur. Ce réseau (32) sert à réfléchir une partie du faisceau optique pour le renvoyer vers la diode (10) à grande surface, ce qui stabilise la longueur d'onde du faisceau optique. Le réseau (32) de la fibre et la facette (12) arrière de la diode (10) à grande surface servent de noeuds à un résonateur externe ce qui limite la diffraction du faisceau optique. Les effets de la fluctuation de longueur d'onde et de la diffraction du faisceau sont ainsi réduits ensemble avec un minimum de composants mécaniques.

Title: Vehicle light weight dead axle and method for forming same
Inventor: SIMON BRIAN A
IPC: B21C23/14
Filed: 2001-09-11
Granted: 2009-06-16
Abstract: A vehicle dead axle is formed of a hollow tube that extends substantially the width of the vehicle and has wheel supporting spindle portions welded upon the opposite ends of the tube. The exterior surface of the tube is generally circular in cross-section. The cross-sectional shape of the opening in the tube is asymmetrically curved relative to the central axis of the tube to form the tube into integral, longitudinally extending, circumferential wall segments of varying wall thicknesses. The axle is oriented so that its thicket wall segments receive the greater of anticipated forces imposed upon the axle during use. The axle is formed by placing a tubular blank within an open die having a die throat and pushing the blank through the die throat by means of a moving ram that engages and pushes against the end of the blank. The ram has an extension that is fitted within the blank as the ram pushes the blank through the space between the extension and the die throat. The extension is asymmetrically shaped in cross section relative to the axis of the throat so as to form the varying thickness circumferential wall segments.

Abstract: A universal/upgrading pulse oximeter (UPO) (210) comprises a portable unit (610) and a docking station (660, 910) together providing three-instruments-in-one functionality for measuring oxygen saturation and related physiological parameters. The portable unit functions as a handheld pulse oximeter. The combination of the docked portable and the docking station functions as a stand-alone, high-performance pulse oximeter. The portable-docking station combination is also connectable to, and universally compatible with, pulse oximeters from various manufacturers through use of a waveform generator (320, 930). The UPO provides a universal sensor to pulse oximeter interface and a pulse oximeter measurement capability that upgrades the performance of conventional instruments by increasing low perfusion performance and motion artifact immunity, for example. Universal compatibility combined with portability allows the UPO to be transported along with patients transferred between an ambulance and a hospital ER, or between various hospital sites, providing continuous patient monitoring in addition to plug-compatibility and functional upgrading for multiparameter patient monitoring systems. The image on the portable display (264, 740) is rotatable, either manually when undocked or as a function of orientation (950). In one embodiment, the docking station (660) has a web server and network interface (1410) that allows UPO data to be downloaded and viewed as web pages over a local area network (1420) or the Internet.

Title: Electromagnetic postal indicia and method of applying same
Inventor: LORD DAN J
IPC: G07B17/00
Filed: 2000-11-16
Granted: 2007-02-20
Abstract: Presented is a system and method of applying postage indicia to a mailpiece utilizing electromagnetic storage technology for the indicia. This method obviates the necessity of visual bar coded indicia, and greatly increases the amount of information which may be included in the postage indicia. This method also significantly reduces the physical space required on the face of a mailpiece (10) to contain the postage indicia information, thus allowing the increased use of advertising and personal information and graphics on the mailpiece. The electromagnetic storage media area (12) may be in the form of a self-adhesive sticker or label (14), or may be integrated within the mailpiece or mailing label. Such integration may be accomplished through the use of embedded magnetic storage media, embedded ferromagnetic fibers, or the inclusion of ferromagnetic powder embedded in the mailpiece itself. Also provided is an apparatus for applying magnetically recordable media on a mailpiece. Such application may be in the form of a spray liquid, magnetic ink, rolled on impression, etc.

Abstract: An electric vehicle driven by electric motors is provided.      The vehicle is switched between forward travel, neutral and reverse travel by a directional speed lever which allows adjustment of the vehicle speed. When the directional speed lever passes through a neutral region at a high speed during forward travel of the vehicle, the vehicle is controlled to shift to normal reverse operation after a lapse of a predetermined period of time since the rotational speed of the electric motors becomes zero, thereby to avoid application of a heavy load to drive circuits for the electric motors.
