Title: Automatic protection switching using link-level redundancy supporting multi-protocol label switching
Inventor: FREDETTE ANDRE N
IPC: H04L1/00
Filed: 2000-06-02
Abstract: A computer network has a plurality of routers that deliver data packets to the network via a plurality of links. At least one router provides automatic protection switching in the event of a link failure. The at least one router includes a plurality of data interfaces for streams of data packets to enter and exit the at least one router; and a backup controller. The backup controller includes a backup path manager, a link monitor, and a backup packet processor. For at least one link of the routing node, the backup path manager identifies a backup routing path for forwarding affected data packets in the event of a failure of the at least one link. The link monitor monitors the plurality of links to determine when a link fails. When a link which has a backup routing path fails, the backup packet processor attaches backup routing path instructions to affected data packets routed over the failed link, and forwards the affected data packets via the backup routing path.

IPC: G01N27/84
Filed: 2000-07-12
Abstract: A portable, battery-operated AC electromagnetic yoke for detecting surface defects in ferrous materials by employing an AC magnetic field. The yoke includes a circuit that produces a quasi AC square wave voltage. The resulting AC magnetic field is the required inspection method of common practice and is capable of demagnetizing upon completion of inspection. A first bank of batteries supplies approximately sixty volts positive DC and a second bank of batteries supplies approximately sixty volts negative DC to power transistors that are in electrical communication with the yoke. Logic circuitry is employed to switch the respective banks of batteries on and off to simulate an AC circuit. The logic circuit includes a clock for generating pulses that are fed to a phase splitter circuit and to a delay and pulse shaping circuit. The respective outputs of those circuits are fed to logic gates that are in electrical communication with a voltage level shifting circuit that triggers the power drivers. A plurality of power resistors in conjunction with the inductor in the yoke provides the proper time constant for the magnetizing current to reach a large enough value to provide sufficient magnetic force to detect the surface defects, demagnetize, and lift ten pounds of ferrous material.

Filed: 1999-08-19
Abstract: The invention discloses enzyme-based optical sensors for detecting blood components which are substrates for oxidative enzymes, the sensors advantageously employing a multiple-layer structure featuring a thin, rapidly responding, optical, oxygen sensing layer. The sensors comprise, in order, a) an enzymatic layer containing an oxidative enzyme or enzyme cascade in a water and oxygen-permeable matrix; b) an oxygen sensing layer containing luminescent dye in a light-transmissive, oxygen-permeable matrix; and which is preferably deposited onto c) a light-transmissive substrate. Embodiments of the invention may further include a rapidly hydrating gas-permeable cover, or spacer, layer deposited over the enzymatic layer. A particulate filler material may be included in an effective amount in the oxygen sensing layer to reduce sample light scattering effects. The sensors of the disclosure may be used to detect creatinine and other enzyme-oxidizable analytes such as glucose, lactate or cholesterol, and may be made easily using standard coating techniques known in the art. These sensors are suitable for multiple analyses, but the materials and methods used allow the sensors to be disposable as well, allowing their wide use in medical and analytical applications.

Abstract: L'invention porte sur une découpeuse comportant un support en quart de cercle vu du dessus où repose le plateau (5). La pièce à découper peut être une tôle d'acier (6). L'arrière de la machine comporte un poteau (2) dépassant du plateau et constituant un pivot vertical auquel sont rigidement fixés un bras supérieur et un bras inférieur (3 et 4) qui peuvent donc se déplacer dans un plan horizontal. Un bâti (7) reposant sur les bras (3 et 4) et sur des roulements (R) est libre de s'éloigner ou de se rapprocher du poteau (2). La branche inférieure (7) du bâti porte l'outil de coupe (16) tandis que sa branche supérieure porte un détecteur (8) servant à suivre le profil à recopier défini par un dessin ou un gabarit placé sur la table (10). L'opération s'effectue au moyen de deux moteurs utilisant des moyens photoélectriques de suivi, l'un des moteurs entraînant une roue (12) frottant sur le gabarit et l'autre agissant sur l'orientation de la roue (12). La roue commandée en direction parcourt la surface du gabarit en suivant les motifs du gabarit, ce qui produit un mouvement correspondant du bâti (7) et par là de l'outil de coupe (16). Cette disposition où la roue (12) entraîne directement le bâti (7) et l'outil de coupe (16) évite les tringleries et accouplements complexes.
