Title: Atrial defibrillator and method for providing pre-cardioversion pacing
Inventor: KREYENHAGEN PAUL E
IPC: A61N1/39
Filed: 1993-10-19
Granted: 2001-07-24
Abstract: An implantable atrial defibrillator provides cardioverting electrical energy to the atria of a human heart in need of cardioversion. The atrial defibrillator includes a first detector for detecting atrial activity of the heart and an atrial fibrillation detector responsive to the first detector for determining when the atria of the heart are in need of cardioversion. The atrial defibrillator further includes a pacing output circuit responsive to the atrial fibrillation detector for pacing the ventricles of the heart at a pacing rate when the atria of the heart are in need of cardioversion and a cardioverter stage for applying the cardioverting electrical energy to the atria of the heart after the pacing output circuit has paced the ventricles for a predetermined number of cardiac cycles. The pacing output circuit stabilizes the cardiac rate of the heart prior to the application of the cardioverting electrical energy.

Title: Location method and panel pressing apparatus
Inventor: BROWN GORDON CLIFFORD
IPC: B21D1/06
Filed: 1993-10-26
Granted: 2000-11-07
Abstract: The invention concerns a method of locating and repairing dents in motor vehicle panels. The initial step in the method is to locate the dent in the panel. This is done by positioning a magnet and a metal ball on or adjacent to opposite surfaces of the panel so that the magnet and ball attract one another through the panel. The relevant one of the magnet or ball is to the location of the dent on one side of the panel with the result that the other of the magnet or ball moves to the dent on the other side of the panel. The magnet is typically carried by a mechanical pressing tool which can then be used to lever out the dent by working the metal around the dent.

Title: Stents and stent-grafts having enhanced hoop strength and methods of making the same
Inventor: PINCHUK LEONARD
IPC: A61F2/90
Filed: 1997-03-13
Granted: 2002-02-05
Abstract: Stents are coated with a polymer such that the polymeric coating binds the crossover points of the wires, or, in the case of a zig-zag stent, binds adjacent zig-zags of wires without occluding the interstices of the stent lattice. Suitable polymers include polyurethane, polycarbonate urethane, polyurethane urea, silicone rubber, polyisobutylene copolymer (with styrene, etc.), polyolefin, polyester, glycolated polyester, polyamide, amorphous polyamide, combinations of the above and the like. Biodegradable polymers such as Polyisobutyrate, polyvalerate, polylactic acid, polyglycolic acid and combinations of these are also suitable.      The polymer can be reacted in place without a solvent, such as two component polyurethanes, or silicone rubbers, or the reacted polymer can be dissolved in an appropriate solvent, for example, dimethylacetamide for the polyurethanes, toluene for the polyolefins, or heptane for the silicone rubbers. In order to enhance bonding of the polymer to the stent wires, the metallic stent can be primed prior to coating. The hoop strength of a polymer coated stent is improved due to locking of the crossover points and preventing free motion of the stent wires relative to each other.

Abstract: A system and method for detecting fault conditions in a recording device (38) disposed within a vehicle (12) having one or more vehicle sensors (48) for monitoring one or more operational parameters of the vehicle (12). The recording device (38) is used to collect vehicle operation data produced by the sensors (48). One implementation of the fault detection technique involves the storing of a current time value at regular intervals during periods in which the recording device is provided with a source of main power. Time differences are determined between consecutive ones of the stored time values, and the time differences compared to a predetermined maximum value. A power loss fault condition is registered when at least one of the time differences exceeds the predetermined maximum value. An indication of the existence of the power loss fault condition may be communicated to a central control station (18) by the recording device (38).
