Publication number: 20050126551Abstract: A method for controlling a fuel system of an internal combustion engine. The method is employed with a fuel system having a source of alcohol-containing liquid fuel, at least one fuel injector, a heat source for heating the liquid fuel in the at least one fuel injector, the heat source capable of heating the liquid fuel to a level sufficient to convert at least a portion thereof from the liquid state to a vapor state and a metering valve operable to achieve a range of flow rates characterized by a valve open versus valve closed duty cycle. The method includes the steps of metering a predetermined amount of fuel based on engine operating conditions, controlling power supplied to the heat source of the at least one fuel injector to achieve a target temperature, determining alcohol concentration of the fuel and adjusting the power supplied to the heat source of the at least one fuel injector based on the alcohol concentration determination.Type: ApplicationFiled: October 28, 2004Publication date: June 16, 2005Inventors: John Mello, Peter Palmer, Jan-Roger Linna

Publication number: 20050026709Abstract: A golf scorekeeping and analysis system (10,11) is provided for facilitating concurrent entry of score data on a handheld computing device (12) during a round of golf and display of a variety of results statistics in numerical and graphical fashions on a display screen (16) at the user's convenience. Data entry and program manipulation is accomplished using only the cursor keys (20). Results comparisons are selectable based on a variety of criteria, particularly including comparison of a golfer's own scoring and shot making averages versus professional statistics. The +/? comparison (94) is used to calculate an optimum practice (106) regimen to facilitate improvement to approach professional statistical values. Each user's data may be separately maintained and a consistency differential for each player is calculated.Type: ApplicationFiled: July 28, 2004Publication date: February 3, 2005Inventors: Peter Palmer, Niklas Back, Paul Dembry

Patent number: 6845760Abstract: An apparatus and method for improving the transient response of a spark-ignited fuel-injected internal combustion engine is disclosed. This is accomplished by employing one or more novel capillary fuel injectors. These devices are port fuel injectors modified by inserting one or more relatively small diameter heated tubular capillaries between the fuel line and a conventional injector. Sufficient heating can be produced so that flash vaporization occurs as the fuel exits the injector. The heaters are turned on using control algorithms that can be based on exhaust gas oxygen concentration, load on the engine, and accelerator pedal position.Type: GrantFiled: January 15, 2004Date of Patent: January 25, 2005Assignee: Chrysalis Technologies IncorporatedInventors: Jan-Roger Linna, Peter Palmer, John Paul Mello, Stuart Bennett Sprague

Publication number: 20040245187Abstract: When elemental iron is in the presence of chlorinated compounds (contaminants) a naturally occurring reaction takes place and the chlorinated compounds are reduced and form harmless compounds. The production of extremely small metal particles containing elemental iron or a mixture of elemental iron and a second metal is imperative to this method of treating contaminants and is the subject of the present invention. When the particle is small enough a surfactant is not required for the particle to do its job. The elemental metal may be kept in an elemental state by keeping it in an oxygen-scavenging environment. This is achieved by either suspending the nanoscale metal in a carbohydrate solution or by injecting a carbohydrate solution in atomized form into the gas used to inject the metal into the subsurface soil. Additionally, the present invention is to a method of using elemental metal to reductively dehalogenate halogenated hydrocarbons, to reduce soluble metals and to treat metalloids in subsurface soil.Type: ApplicationFiled: July 12, 2004Publication date: December 9, 2004Applicant: Arcadis G&M, Inc.Inventors: David Vance, Suthan S.
