Patent CA-2000566-C (CA)
Title: Prosthesis
Inventor: MULLER GUY-HENRI
IPC: A61F2/12
Filed: 1989-10-12
Granted: 1999-12-14
Abstract: A prosthesis, useful as an implant, comprises a peripheral silicone membrane (1) filled with a number of small individual closed cells (5) with a thin silicone membrane and filled with a biocompatible fluid, said small cells (5) being distributed around a central compartment (4) delimited by a closed, relatively thick silicone membrane (6,7), said compartment being filled with an adjustable quantity of a physiological solution.      The prosthesis can be adjusted as to its volume and shape by insertion or extraction of liquid into, or from, the central compartment through a self-sealing silicone membrane without the need of surgery. The prosthesis also overcomes the danger of major loss of fluid due to leaking or rupture of the membrane.

Filed: 1990-01-26
Granted: 1994-02-22
Abstract: On évite des phénomènes de programmation parasite provoqués par les courants de substrat d'un circuit intégré en prévoyant une mesure de ces courants, et un circuit d'invalidation du fonctionnement du circuit intégré quand le résultat de cette mesure dépasse un certain seuil. D'une manière préféré la mesure du courant de substrat est obtenue en réalisant un transistor de type bipolaire (T2) dont la région de base est justement constitué par ce substrat, ou en réalisant un transistor de type à effet de champ (21-23) dont la grille (23) et dont une (21) des régions actives est reliée à la borne de masse du circuit. Mais ces deux liaisons sont différentes. Une des liaisons est directe, l'autre est une liaison soumise aux fluctuations du potentiel du substrat.

Title: Communication switching system
Inventor: BARRI PETER IRMA AUGUST
IPC: H04L12/54
Filed: 1990-02-20
Granted: 1996-05-28
Abstract: Communication switching system wherein for each cell stream to be transmitted through a switching element a virtual path is established from an input link to an output link of this element on the basis of the individual bandwidth used by this cell stream and of the then calculated total bandwidth used on this output link.  For each cell stream a maintenance cell containing the individual cell stream bandwidth is transmitted on the corresponding virtual path and by means of these maintenance cells the total bandwidth used on each output link is re-calculated and it is checked if it is equal to the above mentioned calculated total bandwidth.  The latter is adjusted if a difference is detected.

Patent CA-2034424-C (CA)
Title: Variable gap filling system
Inventor: KEYS JAMES FREDERICK
IPC: B60J10/00
Filed: 1991-01-17
Granted: 2001-03-27
Abstract: A variable gap sealing article for sealing between a first surface and a second surface which are spaced from one another. The article includes an elongated body portion having a width. A first sealing surface is provided on the first side of the width for sealing against the first surface and a second surface is provided on a second side of the width for sealing against the second surface. The body portion includes a resilient contractible portion and an expandable portion. The contractible portion may be contracted and the expandable portion expanded and retained in the expanded position thereby bridging a gap between the first surface and the second surface. The contractible portion is held in a contracted position whereby the resiliency of the contracted contractible portion biases the article toward expansion of its width for assuring sealing between the first surface and the second surface.      In accordance with the method aspects of the present invention, an article as set forth above is utilized to fill a gap or a space between a pair of contiguous spaced surfaces by positioning the article between the surfaces. Thereafter, the expandable portion is expanded and the contractible portion is contracted to fill the space and leave the contractible portion in the contracted position. The expandable portion is also secured in the expanded position. This effectively bridges the gap and the resiliency of the contractible portion biases toward expansion of the width of the article to produce a positive pressure type seal between the surfaces.
