Patent number: 7782983Abstract: A system for demodulation of the Loran Data Channel transmitted over the Enhanced Loran (eLoran) system including a quadrature filter. The quadrature filter calculates the real and quadrature phase components of a received ninth pulse. The resultant components are used to obtain the angle of the ninth pulse. This angle is then compared with a set of pre-tabulated angles/symbols that are calculated using the same quadrature filter on thirty-two different simulated ninth pulses. The closest angle match gives the corresponding symbol. Such twenty-four symbols make up a single Reed Solomon encoded message. This message is then passed through a Reed Solomon decoder and the transmitted message is obtained.Type: GrantFiled: December 18, 2006Date of Patent: August 24, 2010Assignee: CrossRate Technology LLCInventors: Rohit A. Parakh, Zacahariah S. Conover, Michael R. Leathem, Kevin M. Carroll

Publication number: 20040178121Abstract: This invention is a method of oxidizing organosulfur impurites found in fuel streams. The method comprises reacting the organosulfur impurities with an organic hydroperoxide in the presence of a titanium-containing catalyst. The titanium-containing catalyst is obtained by impregnating a siliceous solid with a titanium halide in a hydrocarbon solvent, or a vapor stream of titanium tetrachloride, followed by calcination. The resulting sulfones are more readily removed from the fuel stream than the non-oxidized organosulfur impurities.Type: ApplicationFiled: March 13, 2003Publication date: September 16, 2004Inventors: David W. Leyshon, Lawrence J. Karas, Yuan-Zhang Han, Kevin M. Carroll

Patent number: 6383966Abstract: Highly active and selective epoxidation catalysts are prepared by combining highsurface area silica support or the like, having surface area greater than 1100 m2/g, with a titanium source. The titanium source is a non-oxygenated hydrocarbon solution of a titanium halide or a vapor stream of titanium tetrachloride. The impregnated support is then calcined at an elevated temperature (preferably, in a substantially oxygen-free atmosphere), and, optionally, reacted with water and/or silylated. The resulting materials are highly active heterogeneous epoxidation catalysts for the reaction of olefins with organic hydroperoxides.Type: GrantFiled: June 9, 2000Date of Patent: May 7, 2002Assignee: Arco Chemical Technology, L.P.Inventors: Yuan-Zhang Han, Edrick Morales, Robert G. Gastinger, Kevin M. Carroll

Patent number: 6380406Abstract: A process for forming an olefin epoxidation catalyst is described. The process comprises reacting a tert-alkyl trihydroxysilane with a titanium complex such that the ratio of Si:Ti is 7. The catalyst is very active and selective in olefin epoxidation.Type: GrantFiled: August 4, 2000Date of Patent: April 30, 2002Assignee: Arco Chemical Technology, L.P.Inventor: Kevin M. Carroll

Patent number: 6077300Abstract: An improved above-the-knee prosthesis with an anatomically configured socket is characterized by one or more contours which correspond to a pre-selected anatomical contour of the upper or lower residual thigh. By exaggerating the depth of the contour in the socket as compared with the corresponding contour in the thigh, the socket grips the residual thigh and maintains the femur in proper alignment. The new channels and contours allow the patient using the socket to have improved rotational support and control over the prosthesis by providing structures which the muscles of the upper and lower residual thigh can "grip." The socket snugly contains the thigh and maintains it, throughout the gait cycle, in a proper anatomical position. This fit increases the comfort of the prosthesis and minimizes gait abnormalities common with other artificial limbs. The increased support helps maintain the physical condition of the residual limb.Type: GrantFiled: April 23, 1996Date of Patent: June 20, 2000Assignee: NovaCare Orthotics & Prosthetics East, Inc.Inventors: John A. Sabolich, Kevin M. Carroll

Patent number: 6011162Abstract: Highly active and selective epoxidation catalysts are prepared by combining silica or the like with a non-oxygenated hydrocarbon solution of titanium halide, removing solvent, calcining at an elevated temperature (preferably, in a substantially oxygen-free atmosphere), and, optionally, reacting with water and silylating. The resulting materials are useful heterogeneous catalysts for transforming olefins to epoxides using organic hydroperoxides.Type: GrantFiled: April 15, 1998Date of Patent: January 4, 2000Assignee: ARCO Chemical Technology, L.P.Inventors: Yuan-Zhang Han, Kevin M.

Patent number: 5380267Abstract: A pneumatic compression supplies both positive and negative pressure for operating a medical device. The pulsing sounds generated by the compressor are attenuated by connecting the inlet of the positive pressure side of the compressor and the outlet of the negative pressure side of the compressor to a common resonating chamber. A port in the resonating chamber acts as an outlet for the discharge of excess air in the chamber and an inlet for the entry of make-up air. By adjusting the diameter of the port with respect to the volume of the resonating chamber, sound attenuation can be optimized. In a compact design, the compressor housing serves as the resonating chamber.Type: GrantFiled: June 18, 1993Date of Patent: January 10, 1995Assignee: Datascope Investment Corp.Inventors: James E. Boutelle, Kevin M. Carroll, Jonathan R. Williams
