IPC: H03H17/08
Filed: 2001-02-01
Abstract: A filter arrangement with a linear phase characteristic is constituted by cascade coupling a first filter (F1) and a second filter (F2). The first filter (F1) is an analogue or digital filter designed so that its amplitude characteristic meets a predefined amplitude specification. The second filter (F2) is implemented as the anti-causal version of a fictive digital all-pass filter (APF) that is designed so that its phase characteristic, up to a linear function of frequency, equals the phase characteristic of the first filter (F1).

Patent CA-2337560-A1 (CA)
Title: Method and apparatus for de-interlacing video images
Inventor: PRIMATIC AGESINO JR
IPC: H04N5/44
Filed: 2001-02-21
Abstract: De-interlacing is effected by determining the motion at each missing pixel and, then, interpolating the missing lines to convert an interlaced field to a progressive frame. The interpolation employed for luminance is determined through motion detection. If motion is detected in the image field based interpolation is used and if no motion of the image is detected frame interpolation is used. Specifically, the interpolation is determined by employing a motion metric. The motion metric at a missing pixel is defined by using a prescribed combination of pixel luminance value differences. A spatial median filter is then used to remove objectionable noise from the pixel luminance value differences and to fill in so-called "holes" in the image. Indeed, the spatial median filter can be considered as providing a measure of the overall effect of all pixels that make up the object of the image.

Inventor: QIN S JOE
IPC: G01M99/00
Filed: 1998-10-27
Abstract: An apparatus and method is disclosed for detecting, identifying, and classifying faults occurring in sensors measuring a process. If faults are identified in one or more sensors, the apparatus and method provide replacement values for the faulty sensors so that any process controllers and process monitoring systems that use these sensors can remain in operation during the fault period. The identification of faulty sensors is achieved through the use of a set of structured residual transforms that are uniquely designed to be insensitive to specific subsets of sensors, while being maximally sensitive to sensors not in the subset.  Identified faults are classified into one of the types Complete Failure, Bias, Drift, Precision Loss, or Unknown.

Abstract: L'invention concerne un disque abrasif monolithe, mince et droit, constitué de grains abrasifs durs et rigides et d'un liant fritté comportant un composant métallique et un composant métallique actif, qui présente une rigidité supérieure. Le composant métallique peut être choisi parmi de nombreuses compositions de métaux frittés. Le métal actif, métal capable de réagir pour former un liant au moyen des grains abrasifs dans des conditions de frittage, est présent en quantité efficace pour intégrer les grains et le liant fritté en composite renforcé par des grains. Le disque abrasif préféré est un disque abrasif diamant à liant fritté de cuivre/étain/titane. Un tel disque est utilisé pour les opérations d'abrasion de l'industrie de l'électronique, notamment la découpe de tranches de silicium et de palets en carbure d'alumine-titane. La rigidité de ces nouveaux disques abrasifs est plus grande que celle des disques monolithes droits classiques, ce qui permet d'obtenir une meilleure précision de découpe et de réduire la désintégration du disque, sans pour autant augmenter son épaisseur, ni accroître les pertes concomitantes dues aux entailles.

Filed: 2001-10-26
Abstract: A rover determines a destination and periodically checks the location of the rover against one or more active alert thresholds. One alert threshold is the boundary of an alert area surrounding a destination. The rover sends an alert to a service center alerts a designated party of an impending arrival of the rover at the destination when the rover is within an alert area surrounding the destination. The service center can also alert a designated party when the rover leaves an alert area surrounding a location. The alerts can be communicated via an automated telephone message, a pager message, an e-mail message, or any other means of communication. The alerts can be used for deliveries by directing an alert to a customer expecting a delivery or to a site expecting a vehicle for loading or unloading. In a private context, the alerts can automatically activate systems such as a home appliances or systems in anticipation of a resident's arrival.
