Publication number: 20100211424Abstract: A method and system for scheduling a meeting between a schedule entity and a plurality of booking entities over a communications network. The method comprises presenting a meeting schedule of the schedule entity for access by the plurality of booking entities, such that the meeting schedule defines a meeting period including a start time and an end time and the meeting period is divided into a first meeting interval and a second meeting interval such that the intervals are located in the meeting period between the start and end times. The method also confirms booking of a first meeting for a first booking entity of the plurality of booking entities in the first meeting interval and maintains the availability of the first meeting interval to accept another meeting booking by another booking entity of the plurality of booking entities based on a booking number threshold defining the maximum number of allowed meeting bookings for the first meeting interval.Type: ApplicationFiled: February 13, 2009Publication date: August 19, 2010Inventor: David W.

Publication number: 20100138794Abstract: A process of pairing a wireless PAN (personal area network) device with a system can be facilitated first by assuming default PIN codes that are traditionally used with wireless PAN devices and then by attempting such presumed default codes before querying the user for input. Accordingly, a cumbersome task conventionally required of the user is most often removed. Also, the devices that are paired and connected are preferably graphically conveyed on a display or graphical user interface (GUI) in a manner that solidly implies that each PAN device is connected only to its system, and not (directly) to other PAN devices.Type: ApplicationFiled: November 30, 2008Publication date: June 3, 2010Applicant: Lenovo (Singapore) Pte. Ltd.Inventors: Harriss C. Ganey, David W. Hill, Aaron M. Stewart

Patent number: 7576372Abstract: A method for making a free-standing, single crystal, aluminum gallium nitride (AlGaN) wafer includes forming a single crystal AlGaN layer directly on a single crystal LiAlO2 substrate using an aluminum halide reactant gas, a gallium halide reactant gas, and removing the single crystal LiAlO2 substrate from the single crystal AlGaN layer to make the free-standing, single crystal AlGaN wafer. Forming the single crystal AlGaN layer may comprise depositing AlGaN by vapor phase epitaxy (VPE) using aluminum and gallium halide reactant gases and a nitrogen-containing reactant gas. The growth of the AlGaN layer using VPE provides commercially acceptable rapid growth rates. In addition, the AlGaN layer can be devoid of carbon throughout. Because the AlGaN layer produced is high quality single crystal, it may have a defect density of less than about 107cm?2.Type: GrantFiled: January 26, 2007Date of Patent: August 18, 2009Assignee: Crystal Photonics, IncorporatedInventors: Herbert Paul Maruska, John Joseph Gallagher, Mitch M.

Patent number: 7244348Abstract: A system and method for treating ballast water within an ocean going vessel by generating hypochlorite for treating the ballast water. The system comprises one or more hypochlorite electrolytic cells in fluid communication with a stream of ballast water. A chlorine analyzer is positioned downstream from the electrolytic cells to determine the chlorine concentration of the treated ballast water. A hydrogen separator is connected to the hypochlorite electrolytic cells for venting hydrogen. In the method of this invention, water is taken aboard the ship for ballast in one port. A treatment stream is separated from the ballast water stream and piped to hypochlorite electrolytic cells. Hypochlorite is generated into the treatment stream and the hydrogen byproduct is separated by the hydrogen separators. The treatment stream is then reintroduced to the ballast water to eliminate marine species and pathogenic bacteria from ballast water.Type: GrantFiled: January 18, 2005Date of Patent: July 17, 2007Assignee: Severn Trent de Nora, LLCInventors: Randolfo Fernandez, David W.
