Abstract: La présente invention concerne un matériau de réparation osseuse présentant une consistance de type mastic, particulièrement utile pour la réparation de défauts osseux dentaires tels que ceux causés par une perte osseuse résultant d'une parodontite modérée ou sévère, pour l'augmentation de défauts osseux de la crête alvéolaire, pour le remplissage de sites d'extraction d'une dent ou pour une greffe d'élévation de sinus. Ledit matériau de réparation comprend une substance particulaire résorbable, poreuse qui est dérivée d'un os ou dérivée d'hydroxyapatite de type osseuse ou d'hydroxyapatite synthétique; et, un support résorbable, tel que des polysaccharides de poids moléculaire élevé, tels que de l'acide hyaluronique. Une concentration élevée de substance particulaire dans le mastic améliore la réparation osseuse et nécessite une concentration élevée de support afin de retenir le mastic sur le site de défaut. Pour une densité particulaire d'environ 1,2 g/cc telle que le matériau de greffe osseuse PEPGEN P-15®, une composition préférée comprend environ 55 % en pourcentage en poids du mastic en suspension dans un gel d'acide hyaluronique présentant un poids moléculaire d'environ 1,4 x 10?6¿ daltons et une concentration finale d'environ 56 mg/cc, ledit matériau adhérant à un défaut parondontal osseux et ne s'étendant pas ou ne migrant pas excessivement par rapport au défaut lorsqu'il est maintenu en place par une suture de lambeaux classique.

Inventor: PARK SUNG-WOO
IPC: H04L27/01
Filed: 2005-06-23
Abstract: A method and an apparatus to control an equalizer. A signal to noise ratio of an output of the equalizer is measured, the measured signal to noise ratio is fed back to the equalizer controlling apparatus, and convergence information of the equalizer is monitored and at the same time effective tap information of the equalizer is monitored.  Accordingly, one or more taps can be selected to perform equalization in the equalizer and to control operation of the equalizer. Thus, it is not necessary to estimate channel information in order to properly operate the equalizer. Thus, since the channel information need not be estimated, a configuration of the equalizer is relatively simple.  Additionally, it is possible to select a proper tap depending on a change in a channel environment and to update a corresponding tap coefficient. Accordingly, performance can be improved.
Patent CA-2513973-A1 (CA)
Title: Anchor sheet
Inventor: PACIONE JOSEPH ROCCO
IPC: B32B7/022
Filed: 2004-01-29
Abstract: An improved anchor sheet is described. The anchor sheet can be injection molded from polypropylene and can have a thickness of between 0.031 inches and 0.75. Such an anchor sheet can be molded with hooks and can have an attached resilient layer. Stems integral with the anchor sheet are used to form the hooks, and may be lmm high and 0.55 mm in diameter. The density of stems may be approximately 230 per square inch, or approximately 128,000 stems on a plate. An anchor sheet made in this way makes an excellent field of hooks when installed onto a supporting surface such as a floor. This field of hooks can take an overlying decorative covering such as pieces of loop backed carpet.  When a resilient layer is attached, for example by ultrasonic welding, to the underside of the anchor sheet, between the anchor sheet and the floor, the anchor sheet can have the right degree of "give", so that a user can experience some cushioning effect from the resilient layer below the anchor sheet, but with some level of rigidity so that the load of walking is transmitted across a larger surface and does not "dig" into the resilient layer.
