Patent CA-2209724-A1 (CA)
Title: Levelling instrument
Inventor: BRAUNECKER BERNHARD
IPC: G01C15/00
Filed: 1996-01-18
Abstract: A levelling instrument has an image-forming objective, a picture-taking spatial resolution optoelectronic detector, and electronics and a computing unit for driving the detector and evaluating the detector signals. The image-forming objective is subdivided into several zones of field depth designed each as a different aperture plate. Corresponding partial zones of the detector are associated to the aperture plates. The partial zones of the detector may also be designed as individual spatial resolution detectors.  Since all level indicators, whatever their distance from the levelling instrument, may be sensed in one of the zones of field depth designed as aperture plates and reproduced by said aperture plate, the image-forming objective need not be manually or automatically refocused nor aligned with respect to the target.

Filed: 1997-07-22
Abstract: Method and apparatus for maintaining an ion beam (14) along a beam path from an ion source (12) to an ion implantation station (16) where workpieces are treated with the ion beam. An ion beam neutralizer (44) is positioned upstream from the ion treatment station and includes confinement structure (120) which bounds the ion beam path. An electron source (126) positioned within the confinement structure emits electrons into the ion beam. An array of magnets (124) supported by the confinement structure creates a magnetic field which tends to confine the electrons moving within the confinement structure. An interior magnetic filter field is created inside the confinement structure by a plurality of axially elongated filter rods (208) having encapsulated magnets (224) bounding the ion beam and oriented generally parallel to the ion beam path. This interior magnetic field confines higher energy electrons (300) from leaving the ion beam path and permits lower energy electrons (301) to drift along the ion beam.

Filed: 1997-07-18
Abstract: A method of electrically connecting an integrated circuit (IC) to at least one electrical conductor on a flexible substrate. A flexible dielectric substrate has an IC attachment area and at least one resonant circuit formed thereon. The resonant circuit is formed with a first conductive pattern disposed on a first principal surface of the flexible substrate and a second conductive pattern disposed on a second, opposite principle surface of the flexible substrate. The first conductive pattern is electrically connected to the second conductive pattern such that the first and second conductive patterns form an inductor and a capacitor, with the inductor also functioning as an antenna. The IC attachment area of the flexible substrate is cleaned and the flexible substrate is secured in a fixed position in a plenum to prevent substantial movement thereof. The IC is secured to the IC attachment area of the flexible substrate to minimize movement of the IC relative to the flexible substrate. Wire bonding of the IC to at least one electrical conductor of the resonant circuit is performed to electrically connect the IC to the at least one electrical conductor. A protective covering is applied over the IC and the wire bond to protect the wire bond from being damaged by external forces.

Filed: 1996-01-29
Abstract: L'invention se rapporte à un procédé et à un système nouveaux qui permettent d'éliminer le bruit dans une image en modélisant d'abord le bruit d'une source de signaux vidéo afin d'obtenir des masques de bruit et des valeurs de table de consultation representatives du bruit à différents niveaux de fréquence pour chaque canal, puis à appliquer les masques de bruit et les valeurs de consultation mises en mémoire à un signal vidéo afin d'éliminer le bruit d'image. On extrait d'abord l'image sous forme de signal vidéo électronique fournit par une source de signaux vidéo, puis on le représente sous la forme d'une structure en pyramide: chaque niveau successif de la pyramide est obtenu à partir des valeurs en courant continu du niveau précédent, et il correspond à une bande de fréquences différente du signal vidéo. Une variante du filtrage de Wiener reposant sur l'utilisation des transformées en cosinus discrets permet de filtrer les coefficients de ces transformées à chaque niveau. On rétablit l'image avec un bruit réduit en remplaçant les valeurs en courant continu par les coefficients de transformation en cosinus discrets inverses du niveau suivant, puis en appliquant encore une transformation en cosinus discrets inverse aux résultats.
