Title: Modele perfectionne de stimulateur cardiaque
Inventor: DESMOND NOEL GRAY
IPC: A61N1/362
Filed: 1998-07-31
Abstract: La présente invention concerne, d'une part un procédé permettant de stimuler le coeur, et d'autre part un stimulateur cardiaque. De façon conventionnelle, pour stimuler le coeur, les stimulateurs cardiaques fournissent une impulsion électrique unique pour chaque pulsation cardiaque requise. Dans le cas d'un rythme cardiaque de 60 pulsations par minute, on délivre 60 fois une impulsion d'une durée de 0,5 ms. Cela requiert une quantité importante d'énergie. Selon la présente invention, on stimule le coeur en fournissant une rafale d'une pluralité d'impulsions à montée rapide pour chacune des pulsations cardiaques. Cette utilisation de l'énergie est plus rationnelle. L'invention concerne également des faisceaux d'électrodes pour un stimulateur cardiaque à implantation apicale.

Title: Joint de dilatation
Inventor: BETTS KENNETH H
IPC: E01D19/06
Filed: 2001-10-04
Abstract: L'invention concerne un joint de dilatation destiné à une structure de stationnement comprenant des premier et second rails à monter sur des dalles, au niveau d'extrémités opposées d'un espace entre celles-ci et une plaque de couverture recouvrant les rails et couvrant l'espace, tout en permettant un mouvement relatif entre les dalles. Une série de barres de renversement sont accouplées de manière pivotante au dessous de la plaque de couverture au moyen de joints à rotule et de joints à emboîtement, de manière que des charges latérales imposées sur la plaque de couverture soient directement transmises dans les barres de retournement, minimisant ainsi le risque de rupture par cisaillement entre la plaque de couverture et les barres de retournement. En même temps, les joints à rotule et les joints à emboîtement permettent à la plaque de couverture et aux barres de renversement de basculer les unes par rapport aux autres. Les barres de renversement présentent des parties d'extrémité sphériques qui sont reçues dans des canaux complémentaires dans les rails respectifs, de manière que les barres de renversement maintiennent la plaque de couverture centrée sur l'espace.

Title: Method and apparatus for improving vertical definition of a television signal by scan conversion
Inventor: BIRCH CHRISTOPHER H
IPC: H04N7/01
Filed: 1989-10-06
Abstract: METHOD AND APPARATUS FOR IMPROVING VERTICAL DEFINITION OF A TELEVISION SIGNAL BY SCAN CONVERSION ABSTRACT OF THE DISCLOSURE Scan conversion apparatus for improving the vertical resolution of a television image for display comprises a field store for storing the previously transmitted field and a line store for storing video data representative of the previous line including the most recent picture element. In an interlaced system, the two vertically adjacent picture elements and the intermediate picture element transmitted in the previous field are used to provide five selectable values. The video data is also tested in accordance with three tests comprising a rank ordering test, a vertically sharp transition test and a motion test. According to the results of these tests, one of the five alternative values is chosen as an interpolated value for display with the vertically adjacent values for the currently transmitted field. The selection process may be assisted by the provision of an auxiliary signal indicative of the probability of motion of a predetermined block of data.

IPC: A47L1/08
Filed: 1990-01-03
Abstract: ABSTRACT             In high rise window washing or wall cleaning, safety is is often sacrificed due to one having to continually hold a water laden mop which not only dripped water but hindered the window washer from using both hands on his ascent or descent from any window.My invention not only gives more security but also allows  continual rewetting of window without ever having to descend the ladder. A portable plastic holster containing water and a snug slot for the pistol style window washing mop has proved to be the most practical solution  by far.

Title: Offset wound helical bead for pneumatic tires
Inventor: SHURMAN LOUIS W
IPC: B60C15/04
Filed: 1990-03-29
Abstract: ABSTRACT OF THE DISCLOSURE           A pneumatic tire bead is formed into a spiral coil consisting of a plurality of convolutions or turns of wire.   The wire may be round,  square,  oval  or hexagonal in cross section.  A crimp or offset bend is made in each of the convolutions a distance of one or a fraction of the wire width in each full 360 degree wire turn such that the ends of the bead wire permit the bead side walls to remain in flat parallel planes.   This offset relationship reduces nonuniformity in the tire heretofore produced by spirally wound wire beads.  The bead wire can be wound in a vertical plane or in a radial spiral clock-like spring fashion.  In another embodiment a pair of mirror image offset coils are joined together to form a composite bead preferably for use in heavy duty applications.  In still another embodiment a single flat hoop may be placed between a pair of mirror image offset coils  to  increase  resistance  to  circumferential distortion.

Filed: 1990-09-12
Abstract: ABSTRACT OF THE DISCLOSURE     In a frequency discriminator, a real part of complex-valued symbols which occurs at a first instant of the period of the symbols is equalized so that its intersymbol interference is minimized and an imaginary part of the symbols which occurs at the same first instant is likewise equalized to minimize its intersymbol interference. A real part of the symbols which occurs at a second instant of the period is equalized to minimize its intersymbol interference and an imaginary part of the symbols which occurs at the same second instant is equalized to minimize its intersymbol interference. The equalized first-instant real part is delayed by a first delay circuit by a time interval equal to the interval between the first and second instants, and the equalized first-instant imaginary part is likewise delayed by a second delay circuit. A first multiplier multiplies the output of the first delay circuit with the equalized second-instant imaginary part and a second multiplier multiplies the output of the second delay circuit with the equalized second-instant real part. The output of the second multiplier is subtracted from the output of the first multiplier to generate a signal representative of a frequency variation.
