Abstract: A method and apparatus for creating three dimensional solid forms in metals, ceramics, organics or any combination thereof is made possible using a computer controlled system to create local environmental conditions that favor deposition from a material stream, precursor gas, weld process or plasma. In order to increase control and accuracy, the material can also be placed while the target area is monitored by a broadband poly-spectral imaging system, which provides dimensional, geometrical, chemical composition, stress and temperature feedback to the computer controlling the process. The local environmental conditions in the deposition area are controlled for magnetic, electric, and acoustic fields as well as for temperature, pressure, flow dynamics, and atmospheric composition. Complex materials can be "written" to match a computer's file of a three dimensional shape with virtually any material composition, surface finish, and geometrical complexity. Discrete components, such as microspheres, optical, electronic or any other components or materials that do not lend themselves to the deposition process, can be inserted and the shape written around them to make them an integral part of the final form. While the system can "write" a three dimensional shape it can also be used to "erase" some or all of a shape. The environmental conditions can also be changed so that material can be removed under computer control so that any corrections or final features can be created including such operations as final polishing or surface finishing. The digital files containing the three dimensional image, environmental and compositional data can be sent to remote locations where the data can be used to write a new three dimensional object.

Abstract: L'invention concerne un procédé dans lequel le traitement des eaux usées s'effectue au moyen de biosolides actifs arrangés de manière à tomber en continu à travers le liquide placé dans une cuve, pendant le processus de traitement. Les biosolides sont ensuite pompés du fond de la cuve et remontés à la surface où ils sont distribués. Cette distribution peut s'effectuer à partir d'un réseau approprié de canaux placés au-dessus de la surface de la cuve. Ces canaux fonctionnent à la fois comme distributeurs de biosolides et déversoirs, et l'oxygène est dissout dans le liquide à mesure qu'il tombe sur la surface du liquide et forme des bulles entraînées dans la couche superficielle de l'eau placée dans la cuve. Etant donné que le traitement s'effectue en régime de décantation à faible turbulence, la mise en place de simples déflecteurs permet de créer facilement des zones de décantation pouvant éliminer les biosolides actifs. Une zone de décantation se définit comme n'importe quelle zone munie de déflecteurs qui ne reçoit pas une liqueur recyclée d'un canal de déversoir. Les eaux usées traitées sont déchargées à partir de chenaux classiques placés à l'intérieur ou autour des zones de décantation. Une telle configuration procure de nombreux avantages lorsqu'elle est mise en oeuvre pour le traitement des eaux usées.

Abstract: The present invention provides Cu lines which are enclosed within Cu diffusion barrier layers, for IC structures such as semiconductor devices. The Cu lines (310) have conventional top (316) and bottom (318) Cu diffusion barrier layers and novel sidewall layers (324 and 326) comprising Cu diffusion barrier materials. The present invention also provides for conductive interconnect lines for semiconductor devices which compensate partly or completely for a misalignment between the line etch pattern and the underlying contact element, such as a via plug. The misalignment tolerant line (430) is formed by fabricating novel sidewalls (438 and 440) on the line wherein the sidewalls have a thickness which equals or exceeds the width of the gap (431) which is caused by the misalignment. The misalignment tolerant line compensates for the misalignment gap and thereby prevents etching a trench in the contact element. Trench formation is reduced rather than prevented when the sidewall is thinner than the width of the misalignment gap. In additional embodiments, manufacturing systems (510) are provided for fabricating the structures of the present invention. These systems include a controller (500) which is adapted for interacting with a plurality of fabrication stations (520, 522, 524, 526 and 528).

Abstract: An apparatus and method for transforming imagery recorded by one camera into other imagery that differs from the first imagery, using imagery collected by one or more additional cameras that differ in their characteristics or parameters from the first camera. Example differences include spatial position of the camera, spatial resolution, spectral characteristics and spatial layout. The apparatus generates a synthetic high-resolution image using a high-resolution camera (206) positioned and a lower-resolution camera (208). The high-resolution image data is warped using the lower-resolution data to generate a synthetic high-resolution image (114) having viewpoint of the lower-resolution camera (208). The high-resolution synthetic image generation routine (110) comprises the steps of correcting the spatial, intensity and chromanence distortions of the image data acquired from the high-resolution camera (206) and the lower resolution camera (206) (step 202), subsequently filtering and subsampling the corrected high-resolution data (step 210), computing the parallax between the high-resolution data and the low-resolution data (step 212) and warping the high-resolution image to create a synthetic image (114) of the scene (200) having a viewpoint of the lower-resolution camera (208) (step 214).

Abstract: L'invention concerne une précompensation des pertes d'énergie à haute fréquence prévues dans les supports de transmission, de manière à éviter le brouillage intersymboles. On effectue la précompensation via une forme d'onde à préaccentuation (200), c'est-à-dire en attaquant le signal différentiel pour le porter à une valeur supérieure à la normale en bordure de signal. La préaccentuation augmente la pente des bordures à l'intérieur des données présentant beaucoup de transitions, par rapport aux données présentant moins de transitions, ce qui permet de compenser les effets passe-bas du câble de transmission. L'invention concerne en outre un contrôle adaptatif (506) permettant d'éviter que la variation des conditions de fonctionnement n'engendre des formes d'onde à préaccentuation (302). Selon une variante, on suit le fonctionnement d'un circuit d'attaque de répétition (504) pour chaque circuit d'attaque principal (502), lequel fait l'objet d'un contrôle adaptatif en fonction de la réaction fournie par le circuit d'attaque de répétition (504). Selon une autre variante, plus complexe et plus efficace, on mesure le signal et l'impédance de ligne à la sortie du circuit d'attaque principal (502) et l'on soumet ce circuit (502) à un contrôle adaptatif (506) en fonction des résultats obtenus.
