Title: Method and apparatus for attaching connective tissues to bone using a knotless suture anchoring device
Inventor: FOERSTER SETH A
IPC: A61B17/04
Filed: 2002-12-19
Abstract: An innovative bone anchor (46) and methods for securing soft tissue, such as tendons, to bone, which permit a suture attachment that lies entirely beneath the cortical bone surface. Advantageously, the suturing material between the soft tissue and the bone anchor is secured without the need for tying a knot. The suture attachment to the bone anchor (46) involves the looping of a length of suture around a pulley within the bone anchor, tightening the suture and attached soft tissue, and hahing a lumen containing a plurality of suture- locking elements (62a,62b) that clamp the suture therein. The locking elements (62a,62b) may be this and C-shaped. One or more locking plugs (68a,68b) attached to separable actuation rods (70) displace axially within the lumon and act on the locking elements (62a,62b) to displace them radially. A generally uniform passage through the locking elements (62a,62b) in their first positions converts to a smaller irregular passage after the locking plig (68a,68b) displaces the elements (62a,62b) to their second positions, thus effectively clamping the suture. The bone anchor (46) further may include locking structure (72a,72b) for securing itself within a bone cavity.

Abstract: Selon l'invention, un détecteur de parcours (100) utilise des statistiques de vitesses auxquelles des signaux de préambule sont détectés pendant une durée prédéterminée. Pour un segment de valeurs de retard pour lequel la vitesse de détection est faible, la fréquence d'échantillonnage de calcul de valeurs de corrélation est diminuée et le nombre d'ensembles de corrélateurs utilisé pour la détection de signaux de préambule est diminué. Des ensembles de corrélateurs disponibles du fait de ladite diminution sont utilisés pour détecter des parcours de signaux de message, augmentant ainsi la vitesse de fonctionnement des récepteurs Rake d'un décodeur (200) pour améliorer la sortie des signaux de message. De plus, les statistiques des vitesses de détection de signaux de préambule sont périodiquement mises à jour, et lorsque la vitesse de détection de signaux de préambule du segment de valeurs de retard pour lequel la vitesse d'échantillonnage a été réduite devient plus élevée, le nombre d'ensembles de corrélateurs utilisé pour la détection de signaux de préambule est augmenté de manière à ramener la vitesse d'échantillonnage à sa valeur d'origine.

Abstract: On décrit diverses méthodes de production de vaccins à partir de pseudo-particules virales recombinantes (VLP). Premièrement, les VLP sont déassemblées en populations intermédiaires d'encapsidation. Chaque population intermédiaire d'encapsidation est soumise, par exemple, à une conjugaison chimique de fragments peptidiques ou nucléiques uniques pour former des populations séparées. Une quantité préétablie d'un ou de plusieurs intermédiaires d'encapsidation différents issus de ces différentes populations est ensuite mélangée et assemblée pour former des VLP intactes entourant un noyau d'acide nucléique et composées de différents intermédiaires d'encapsidation, si bien que les VLP réassemblées présentent plus d'un peptide ou d'un acide nucléique. L'acide nucléique peut fonctionner seul comme squelette ou être mis au point pour exprimer une protéine immunomodulatrice dans une cellule eucaryote.

Abstract: This is a Variable Transformer Hydro Cost Reducer (universal). The main components of the system are low speed induction motor, bars, chains and sprockets, wiring, safety switches, the gearbox, the dynamo, primary and secondary transformers. and outlet. The components are arranged in a proper sequence that allows current to travel from the hydro inlet into the induction motor, then to turn a sprocket feeding into the gearbox. The mechanics of the gearbox transmit power to a high speed rotating bar (1800 RPM) which enters the dynamo. This dynamo transforms increased mechanical energy into increased electrical power that travels through the wiring to the secondary transformer(s) which steps up the voltage to 2400 volts. This increased current is channeled by the step- down transformer(s) into the voltage required by the business or residence location at 20% of normal cost and 20% of normal power consumption.
