Publication number: 20080295760Abstract: The wear indicator (10) is for a workpiece portion of a personal care appliance such as a power toothbrush (IS). The wear indicator includes a member of water-soluble material which has magnetic particles positioned therein. Upon repeated contacts with water, which correlates with use of the device, the member dissolves or swells, depending on the material selected. A magnet positioned adjacent the member influences the position of the magnetic particles in the member, aligning them into a three-dimensional image which is recognizable by the user, wherein the appearance of the image correlates with sufficient wear on the workpiece that it should be replaced.Type: ApplicationFiled: October 4, 2006Publication date: December 4, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventor: Ytsen Wielstra

Publication number: 20080295762Abstract: Disclosed is a method for producing, controlling the shape and size oft Pb-chalcogenide nanoparticles. The method includes preparing a Pb (Pb) precursor containing Pb and a carboxylic acid dissolved in a hydrocarbon solution and preparing a chalcogen element precursor containing a chalcogen element dissolved in a hydrocarbon solution. The amount of Pb and chalcogen in the respective precursor affords for a predetermined Pb:chalcogen element ratio to be present when the Pb precursor is mixed with the chalcogen element precursor. The Pb precursor is mixed with the chalcogen element precursor to form a Pb-chalcogen mixture in such a manner that Pb-chalcogenide nanoparticle nucleation does not occur. A nucleation and growth solution containing a surfactant is also prepared by heating the solution to a nucleation temperature sufficient to nucleate nanoparticles when the Pb-chalcogen element mixture is added.Type: ApplicationFiled: May 30, 2007Publication date: December 4, 2008Applicants: Toyota Engineering & Manufacturing North America, Inc., University of California, BerkeleyInventors: Taleb Mokari, Minjuan Zhang, Peidong Yang

Publication number: 20080295802Abstract: The invention concerns a method for determining the timing of an injection cycle relative to an operating cycle of a four-stroke engine (ECH, ADM, COMP, DET), the timing being possibly correct or wrong, the method including the step of operating the engine while modifying a first operating parameter of the engine adapted to bring about on the engine operating effects which are different depending on whether the timing is correct or wrong; it consists in simultaneously modifying a second operating parameter of the engine adapted to bring about on the engine operating mode effects which compensate the effects modifying the first operating parameter of the engine when the timing is correct, and which do not compensate the efforts modifying the first operating parameter of the engine when the timing is wrong.Type: ApplicationFiled: July 18, 2006Publication date: December 4, 2008Applicant: VALEO SYSTEMES DE CONTROLE MOTEURInventors: Damien Poignant, Pierrick Plouzennec

Publication number: 20080295803Abstract: A machine having an internal combustion engine includes a camshaft wheel rotatably driven by a crankshaft of the engine. The camshaft wheel includes a plurality of circumferentially spaced teeth. A first engine angle indicator is positioned among the circumferentially spaced of the camshaft wheel and is one of a missing tooth and an additional tooth. A second engine angle indicator is positioned among the circumferentially spaced teeth of the camshaft wheel less than about 90 degrees from the first engine angle indicator. The second engine angle indicator is also one of a missing tooth and an additional tooth. A camshaft wheel sensor produces a pulsetrain in response to detection of the plurality of circumferentially spaced teeth and additional teeth.Type: ApplicationFiled: May 29, 2007Publication date: December 4, 2008Inventors: Michael Snopko, Robert Weber

Publication number: 20080295804Abstract: An engine includes a fuel delivery system having a fuel rail and fuel delivery devices, such as fuel injectors, that deliver fuel to corresponding cylinder assemblies. The use of the fuel rail and fuel injectors allows unused fuel to be purged from the engine at the end of the engine's operating cycle, thereby minimizing the creation of fuel vapor within the engine. The fuel delivery system also includes fuel rail coupling members that are constructed and arranged to secure each cylinder assembly to the fuel rail and to absorb load generated by the corresponding cylinder assembly on the fuel rail during operation. The fuel rail coupling members allow motion of the cylinder assemblies relative to the fuel rail during operation and minimize the application of potentially damaging forces on the fuel rail.Type: ApplicationFiled: June 1, 2007Publication date: December 4, 2008Applicant: Lycoming Engines, a division of Avco CorporationInventors: Scott E.

Publication number: 20080295806Abstract: An engine comprises a block, a piston, a head, a fuel injector, and a sleeve. The block includes at least one bore. The piston is configured to reciprocate within the bore. The head is coupled to the block and defines with the block and the piston a combustion chamber. The fuel injector is coupled to the head and is configured to deliver fuel to the combustion chamber. The fuel injector includes an actuator extending between a first axial position and a second axial position along a longitudinal axis of the fuel injector. The sleeve is coupled between the head and the fuel injector and extends between a third axial position and a fourth axial position along the axis of the fuel injector. The area between the first and second axial positions at least partially overlaps the area between the third and fourth axial positions.Type: ApplicationFiled: June 4, 2007Publication date: December 4, 2008Applicant: Caterpillar Inc.Inventors: David Y.
