Inventor: TUGGLE W GREGORY
IPC: F16L27/08
Filed: 2000-03-01
Abstract: An improved vent system has a rotatable connection between flexible conduits, which carry heated air from the dryer to an external location, such as the atmosphere. The vent system consists of a swivel coupler rotatably connecting a pair of flexible exhaust conduits, one of which is readily attachable to a dryer exhaust outlet, which discharges exhaust air from the dryer, and the other of which is readily attachable to an outlet pipe, which carries exhaust air from the flexible exhaust conduit through a wall and to the atmosphere. Each flexible exhaust conduit, which is laterally flexible and axially extensible, includes a segmented elbow allowing bending up to approximately a right angle in one direction. The swivel coupler includes a rotatable joint wherein an annular extension on one half of the connector travels in an annular indentation in the other half so as to enable rotation therebetween.  Through a combination of the flexible exhaust conduit, the segmented elbows, and the swivel coupler, an easy-to-assemble vent system having relatively few parts can be efficiently and safely installed by installers possessing even low levels of skill.

Patent CA-2306593-A1 (CA)
Inventor: HAMBURG MARK
IPC: G06T15/50
Filed: 2000-04-25
Abstract: A method and apparatus for erasing a feature from a digital image. The method includes identifying a plurality of tip regions on the image each including multiple pixels of the image and each covering a portion of the feature and sequentially processing the tip regions to erase the feature. The sequential processing includes determining an erasure color, defining a color match function for the tip region, applying the color match function to each pixel in the tip region including determining a color match value for each pixel and completely erasing ones of the pixels in the tip region that have a color match value greater than a threshold value. For a pixel having a color match value less than the threshold, an erasure function is applied to the target pixel. A contribution of the erasure color is removed from a color associated with the target pixel where the effect of each action of processing a tip region is recorded in the digital image before any subsequent action of processing a tip region is performed.
Patent CA-2308141-A1 (CA)
Inventor: OSAWA YOSHITOMO
IPC: G06F21/62
Filed: 1998-10-19
Abstract: On décrit un procédé et un système de transfert d'informations mettant en oeuvre un indicateur de mode de cryptage (EMI). On décrit plusieurs modes sécurisés de communication d'informations dans lesquels des données (représentant un travail audiovisuel, par exemple) peuvent être transmises d'un support source vers un support cible (station réceptrice) suivant différents de modes sécurisés. Dans un desdits modes sécurisés (mode EMI A), l'information transmise ne peut être copiée sous une forme complète: c'est le niveau de protection le plus élevé. Dans un deuxième mode sécurisé (mode EMI B), l'information transmise peut être copiée une seule et unique fois par le support cible. Dans un troisième mode sécurisé, l'information n'est pas cryptée et peut être copiée librement. Selon le mode sécurisé A ou B choisi, un processus de cryptage différent est mis en oeuvre par le support source pour crypter la transmission. De plus, selon le mode sécurisé A ou B choisi, un processus de cryptage différent est mis en oeuvre par le support cible pour décrypter la transmission. Cet invention est particulièrement utile pour des transmissions entre un support source et un enregistreur de train numérique ne possédant pas la capacité d'extraire certaines informations de cryptage d'une en-tête de paquet. En mettant en oeuvre un procédé de cryptage différent pour chaque mode de transmission, un support non autorisé placé entre le support source et lesupport cible et pouvant modifier le code EMI ne pourra pas restituer ou enregistrer le travail audiovisuel, étant donné que le procédé de décryptage choisi est différent du procédé de cryptage mis en oeuvre.
