Patent number: 7404943Abstract: Methods of enhancing the solubility of a fluorinated compound in an organic solvent are provided. In one embodiment, carbon dioxide gas pressure is applied to the solvent at a pressure effective to enhance the solubility of the fluorinated compound. The method may further include recrystallizing the fluorinated compound by reducing the pressure of the carbon dioxide gas. Also provided are methods of conducting a reaction using a fluorinated compound in an organic solvent. In one embodiment, the method comprises applying carbon dioxide pressure to an organic solvent comprising at least one substrate and a fluorinated catalyst, in an effective amount to solubilize the catalyst; and permitting the fluorinated catalyst to catalyze the reaction of the substrate to form a product. The catalyst is optionally separated from the reaction product and solvent after the reaction by the release of the pressure.Type: GrantFiled: May 30, 2002Date of Patent: July 29, 2008Assignees: The Regents of the University of California, Georgia Tech Research CorporationInventors: Charles A.

Publication number: 20070288165Abstract: A method and system for degimbalization of sensor outputs is provided. Data output from an embedded GPS inertial navigation system (EGI), which is mounted within a gimbaled system on a vehicle, is processed to provide degimballed navigation data. Generally, motion of the EGI is due to the vehicle motion and the gimbal motion. To provide navigation information relating solely to the vehicle, effects of the gimbal motion within the EGI outputs can be removed.Type: ApplicationFiled: May 26, 2006Publication date: December 13, 2007Applicant: Honeywell International Inc.Inventors: Charles Eckert, Reed May, Maurice Shrader-Frechette, Delroy Sowada, Michael Symonds, Michael Vaujin, Jeff Willis

Patent number: 7000838Abstract: A method for processing scanned code data, including a plurality of strings, to determine whether the scanned code data is part of a valid code begins by examining a first string of a first scanned code data. A cluster is opened with the first string if the first string contains a start pattern. At least one valid middle portion of the first string is identified and a transition position count associated with the at least one valid middle portion is stored. A second scanned code data is searched for a second string matching at least part of the first string in the cluster. If a match is found, then the second string is added to the end of the cluster. The cluster is closed upon detection of a stop pattern and is then decoded.Type: GrantFiled: December 23, 2003Date of Patent: February 21, 2006Assignee: Accu-Sort Systems, Inc.Inventors: Charles Lapinski, Charles Eckert, Richard Skokowski, James Cox, William Scott, Edward Chaleff, Jeffrey G.

Publication number: 20040064252Abstract: A method and system for processing pulse signals within an inertial device is provided. The inertial device may have inertial sensors, such as accelerometers and gyroscopes. The inertial sensors may output signals representative of a moving body's motion. The signals may require correction due to imperfections and other errors of the inertial sensors. The inertial device may receive signals from the inertial sensors and process the signals on a signal-by-signal basis so that when processing the signals, the inertial device at least recognizes which sensor output a signal and when the signal was output. The inertial device may then correlate signals that were output from the inertial sensors at selected times in order to transform the signals into a desired navigational frame of reference.Type: ApplicationFiled: September 26, 2002Publication date: April 1, 2004Applicant: Honeywell International Inc.Inventors: Jeffrey Kirkland, Charles Eckert

Patent number: 6432486Abstract: A method treats an article and more specifically an aircraft surface in order to prevent icing and to provide a coating that emits very low volatile organic compounds (VOC) during application and setting. Icing on critical aircraft surfaces creates dangerous conditions that impair the stability of the aircraft. The specific areas are referred to as “cold-soak” conditions and some areas on the “leading edges” of the wings. The invention eliminates icing on these surfaces. Ice will not form on the surface of certain polymer coatings with low surface energy such as Teflon. This is a consequence of the high contact angle between the water droplet and the surface that establishes a non-wetting surface. The invention implements such coatings and a deposition process. The coating may be used for other objects such as automobiles, consumer products, such as refrigerators, stoves, etc.Type: GrantFiled: August 15, 2000Date of Patent: August 13, 2002Assignee: Delta Airlines, Inc.Inventors: Henry G.

Publication number: 20010045462Abstract: A scanner can read machine-readable code on an object. A scanner has a scanning device, a data device, and a registration device. The scanning device can repetitively scan the code and provide a scan signal repetitively corresponding to at least fragments of the code. The data device is coupled to the scanning device and responds to its scan signal for repetitively storing it. The registration device is coupled to the data device for reconstructing the code from at least two of the fragments of the code by relatively shifting the code fragments until they are in registration.Type: ApplicationFiled: March 2, 2001Publication date: November 29, 2001Inventors: Charles Lapinski, Charles Eckert, Richard Skokowski, James Cox, William Scott, Edward Chaleff, Jeffrey G.

Patent number: 6028018Abstract: An improved wet wipe includes a multiple layer basesheet to provide a unique combination of properties to the wipe which are not capable in a single layer basesheet. The layered basesheet includes at least two layers which include different fibers and have different physical properties. One of the layers may include polyethylene fibers to provide a soft, gentle feel for contacting the skin of the user during use while the other layer may include polypropylene fibers to provide strength and resiliency to the wipe to withstand the forces exerted by the user, and maintain its shape and integrity in use.Type: GrantFiled: September 6, 1996Date of Patent: February 22, 2000Assignee: Kimberly-Clark Worldwide, Inc.Inventors: John David Amundson, John Charles Eckert, Mark George Everson, David Martin Jackson, Walter Theodore Schultz, Charles Allen Smith, David Craige Strack
