Patent number: 6122599Abstract: An apparatus for analyzing particles suspended in a fluid. The fluid has electrical properties different from that of the particles. The fluid and particles move from a first fluid containing portion to a second fluid containing portion through a conduit or aperture. A first pair of electrodes, each electrode of the pair being in a respective fluid containing portion. A constricted electrical path is defined between the first and second electrodes, and the path extends along the aperture. At least one other pair of electrodes is positioned in a non-encircling arrangement, and are aligned with each other and transversed to the constricted electrical path. This configuration eliminates many common errors suseptible to other devices.Type: GrantFiled: February 13, 1998Date of Patent: September 19, 2000Inventor: Shailesh Mehta

Patent number: 6095969Abstract: A surgeon-implantable, fluid-filled, flexible device for automatically controlling stress incontinence in female patients employs a flexible diaphragm element positioned in the patient's abdominal space to compress in response to increases in intraabdominal pressure. Upon such compression of the diaphragm, pressurized fluid flows therefrom via a flexible tubing, optionally via a flow control element, to an inflatable urethra-constricting element in fluid communication therewith and positioned over the patient's urethra close to her bladder neck. Thus, when the patient experiences an increase in intraabdominal pressure, e.g., when she coughs, fluid from the diaphragm flows rapidly to the urethra-constricting element which presses against and forcibly constricts the urethra adjacent thereto. Upon abatement of the intraabdominal pressure, the flow control element releases fluid from the urethra-constricting element which then ceases to press on the urethra.Type: GrantFiled: March 3, 1998Date of Patent: August 1, 2000Inventors: Mickey M. Karram, Bryan D. Knodel

Patent number: 6086606Abstract: A manually-operable surgical tool, suitable for laparoscopic operations, has separable parts which cooperate to move a pair of end effector elements which can be readily replaced by another pair of end effector elements. A handle portion enables controlled longitudinal movement of an elongate inner element relative to an outer surrounding tubular element. The tubular element has a distal end with a first cleft and a pair of parallel cantilevered inwardly-oriented opposed cam pins. The distal end of the elongate inner element is provided with a second cleft and a transverse force-application pin. The selected end effector elements rotatably fit inside the cleft of the inner element to receive an applied force via the force-application pin. Each end effector element has a blind-ended cutout having an open end for engaging at least with a corresponding one of the cam pins.Type: GrantFiled: May 6, 1998Date of Patent: July 11, 2000Inventors: Bryan D.

Patent number: 6052990Abstract: A double U shaped exhaust pipe having varying internal pipe diameters for increasing horsepower, designed within internal combustion engine vehicle racing or other rules that limit such features as overall size. A first stage portion of the exhaust pipe produces a first periodic flow of exhaust, with a vacuum pulse created where the pipe internal diameter increases upon the exhaust reaching a second stage portion. A third stage portion of the exhaust pipe produces a third stage periodic flow of exhaust upon the exhaust reaching an increased pipe internal diameter at a fourth stage portion. These periodic pulsed flows are matched to the opening of the intake and exhaust valves of the engine for a selected engine speed range. The matching of a vacuum pulse to the opening exhaust valve improves engine performance by drawing exhaust gases from the engine.Type: GrantFiled: June 24, 1999Date of Patent: April 25, 2000Assignee: Competition Cams, Inc.Inventor: Sheldon Gecker, Jr.
