Title: Methods for the diagnosis and ablation treatment of ventricular tachycardia
Inventor: IDEKER RAYMOND E
IPC: A61B5/363
Filed: 1993-01-28
Granted: 2002-09-17
Abstract: A closed-heart method for treating ventricular tachycardia in a myocardial infarct patient afflicted with ventricular tachy-cardia is disclosed.The method comprises, first, defining a thin layer of spared myocardial tissue positioned between the myo-cardial infarct scar tissue and the inner surface of the myocardium (the endocardium) of the patient, and then ablating the thin layer of spared myocardial tissue by a closed-heart procedure with an ablation catheter. Apparatus for carrying out the method is also disclosed. Also disclosed is a method for prognosing the likelihood of ventricular tachycardia occurring in a myocardial in-farct patient not previously diagnosed as afflicted with ventricular tachycardia. The method comprises detecting a thin layer of spared myocardial tissue positioned between the myocardial infarct scar tissue and the inner surface of the myocardium (the en-docardium) in the patient.

Abstract: A winding support body (6, 10) for transformers/reactors with a winding of a tape-formed superconductor (8), wherein the support body consists of a substantially straight, circular-cylindrical tubular body which, on the side where the winding is to be placed and out towards the two ends, is provided with a helical slot with a plane surface with a width equal to the width of the tape. In this way, each turn of the slot around the support body forms a surface which practically constitutes the envelope surface of a straight frustum of a cone. The angle (v) between a generatrix (9) of the envelope surface and the axial centre line of the sup-port body increases for each turn out towards the ends of the support body in such a way that the envelope surface at all points coincides with the direction of the magnetic field.

Abstract: Ce dispositif concerne l'aide au pilotage d'un aéronef, avion ou hélicoptère, par mauvaise visibilité, à l'atterrissage, en approche finale avant le toucher des roues. En cas de mauvaise visibilité, les atterrissages sont facilités par des équipements radioélectriques ILS qui permettent une approche automatique du seuil de piste et il ne reste plus qu'à effectuer un arrondi pour le toucher des roues qui doit s'effectuer dans une certaine zon e en début de piste. Il arrive, en cas de mauvaise visibilité, que cette zone de toucher de roues soit difficile à apprécier ce qui entraîne des risques de poser trop long. Le dispositif selon l'invention a pour objet d'émettre une alarme en cas de dépassement de la zone nominale de toucher des roues. Il comporte des moyens d'intégration de la vitesse sol, des moyens de détection de franchissement par valeur inférieure d'un seuil de hauteur par rapport au sol caractéristique du franchissement du seuil de piste déclenchant lesdits moyens d'intégration et des moyens de détection de franchissement par valeur supérieure d'un seuil de distance opérant sur le signal délivré par les moyens d'intégration et engendrant une alarme.</SDOAB >

Title: Multiple access cellular communication with dynamic slot allocation and reduced co-channel interference
Inventor: PAPADOPOULOS HARALABOS C
IPC: H04W72/04
Filed: 1995-11-14
Granted: 1999-07-20
Abstract: An  apparatus  and  method  for  reducing  co-channel interference  in  multiple-access  cellular  communication systems in which frame time or frequency slots are allocated between uplink and downlink.  An omnidirectional antenna or a set of directional antennas are used in each cell base station to communicate with users.  The frame slots in which the antennas communicate uplink and downlink information are arranged  in  accordance  with  a    predetermined  frame organization to reduce mixed co-channel interference (CCI). Mixed CCI occurs when a downlink transmission from one base station antenna in a given cell interferes with uplink reception in another base station antenna in a frequency reuse  (FR) cell.   A potentially-interfering antenna in a given  cell  is  therefore  directed to  transmit  downlink information in a different portion of the frame than that in which a potentially-interfered-with antenna in the frequency reuse cell receives uplink information.  The frame slots may be allocated such that only a portion of the available slots are dynamically allocated in accordance with user demand, while the remaining portions are assigned to either uplink or downlink communication.

Abstract: The present invention concerns a stencil for the depositing and gauging of more or less thick, point-base coats of a viscous product.To remedy the problems found with a serigraphic screen made of polyester or metal cloth and a metal stencil, the present invention proposes use of a solid sheet of uniform composition made of synthetic material and, preferably, polyester without the inclusion of wires. This polyester solid sheet is bored mechanically or thermally at the places desired. Since the polyester cloth is solid, it admits of tension forces greater than those of wire mesh cloths or at least equal to those of metal stencils.

Abstract: The invention relates to a catheter comprising a tube- like basic body with a proximal and a distal end, a connecting member arranged to the proximal end, and a tube-like end-section at the distal end which is pliable to such an extent, that it does not retain its shape. As a result this tube-like end-section is guided and carried along by the surrounding flow, in particular, when the catheter has been introduced into the vascular system of a patient, by the flow of the surrounding blood. Suitable materials of which to make the pliable end- section are for instance LDPE or PVC plasticized with PUR with a coating of PTFE. The end-section may comprise a marking element and/or filling material as a result of which this end-section becomes visible when using X-rays and/or under NMR conditions.

Abstract: A communications system providing a means for dynamically controlling system performance during times when communications traffic substantially changes to prevent blocking service while maintaining communications quality. The communications system provides such dynamic control for voice and/or video communications. For example, a voice communications system according to the present invention provides a means for increasing the effectivevoice capacity during times of increased voice traffic in a given service area, and decreasing the effective voice capacity during time of decreased voice traffic, wherein the decrease in the effective voice capacity provides an increase in voice quality. In one illustrative embodiment, when the voice traffic increases to a given threshold level, the system implements speech compression on selected channels to increase the effective capacity to that service area. In another embodiment, thesystem combines two compressed channel into one to increase the effective capacity even further.

Title: Active harmonic filter and power factor corrector
Inventor: SHERO DAVID J
IPC: H02J3/01
Filed: 1997-08-08
Granted: 2004-11-16
Abstract: An active harmonic filter selectively sources current to or draws current from power lines. The active harmonic filter includes a controller which executes a predictor routine which predicts the current to be supplied to or drawn from the power line at a time t+.DELTA.t to reduce load induced phase differences between the line voltage and the line current. An integrating slow control routine integrates difference currents between actual line currents and desired line currents in equivalent segments of time in different cycles of the power line. The integrated differences may be combined with proportionally controlled difference currents to reduce or eliminate harmonic line currents. A current balancing routine enables the active harmonic filter to balance currents in two or more lines of a polyphase power line. The predictor, integrating slow control and current balancing routines, may be used singly or in combination to improve the condition of line currents on the power lines.

Both zones consist of the material of the main body with controlled proportions of the additives. Both zones are formed from metallic mixed crystals and chemical compounds containing the substances of the main body and/or additives, the phases in the edge zone and mixed zone being set to defined concentration levels.
