Publication number: 20140048034Abstract: A system and a method for improving fuel efficiency of an engine include the application of at least a pair of magnets coupled to opposite sides of a crankcase ventilation passageway and oriented substantially parallel to each other such that an attractive magnetic force is applied transverse to the passageway. The magnetic force causes realignment of lubricant molecules such that the lubricant molecules substantially cover fuel molecules to increase the compression ratio of the engine thereby improving the fuel efficiency. A system for enhancing brake performance and a magnet installation kit are also disclosed.Type: ApplicationFiled: October 21, 2013Publication date: February 20, 2014Applicant: Mackson LimitedInventors: Chiu Hon Cheung, Michael Kwok Lau Cheung

Publication number: 20090283365Abstract: A system and a method for improving fuel efficiency of an engine include the application of at least a pair of magnets coupled to opposite sides of a lubricant return passageway and oriented substantially parallel to each other such that an attractive magnetic force is applied transverse to the passageway. The magnetic force causes realignment of lubricant molecules such that the lubricant molecules substantially cover fuel molecules to increase the compression ratio of the engine thereby improving the fuel efficiency. A system for enhancing brake performance and a magnet installation kit are also disclosed.Type: ApplicationFiled: May 14, 2008Publication date: November 19, 2009Inventors: Chiu Hon Cheung, Michael Kwok Lau Cheung

Publication number: 20070012582Abstract: A container for CDs or DVDs include a case having lid, spine, and base portions, and a main hinge structure including a spaced pair of hinge posts projecting forwardly from the base portion; and a main tray pivotally connected to the main hinge structure and having a secondary hinge structure pivotally supporting a secondary tray, the trays being movable as pages of a book. The main tray can have an additional secondary hinge structure engaging another secondary tray. Each of the trays can be double sided for retaining up to seven disks that contact their supporting structures in closing of the case. The main tray can have oppositely projecting rim portions for nesting the secondary trays flush with the main tray.Type: ApplicationFiled: July 15, 2005Publication date: January 18, 2007Inventor: Kwok Lau

Publication number: 20050169518Abstract: A method for improved, automated, repeatable color matching on materials with different properties is provided. The method includes color matching on different materials using acquired, manipulated, and synthetic reflectance curve data. In one example, resulting synthesized reflectance data is employed in formulating a matching colorant. An example method uses a spectrophotometer to collect reflectance curve data from a physical sample colored to a desired color. The reflectance curve data is employed to produce computer display outputs of substrates as they would be appear if colored with the desired color. The method includes using a colorimeter to collect calorimetric data from the outputs on the display. The sets of colorimetric data are compared and data that facilitate manipulating the reflectance curve data associated with the desired color is produced. The synthetic reflectance curve data facilitates producing matches for the various substrates as colored and displayed on the computer display.Type: ApplicationFiled: January 29, 2004Publication date: August 4, 2005Inventors: Christopher Boston, Kwok Lau

Publication number: 20050084835Abstract: A karaoke system with built-in camera includes a decoder, a camera system, and a video selector. The decoder (e.g., a CDG decoder) receives data from a disc and provides a first video signal having graphics, e.g., for lyrics of a selected song. The camera system captures an image of a live scene and provides a second video signal. The video selector combines the first and second video signals to obtain a third video signal and can provide the first, second, or third video signal (e.g., based on user control) as an output video signal. A color eliminator can filter out a designated frequency (e.g., for a designated color such as blue) in the first video signal to provide a better output image for the third video signal. The decoder and camera system are synchronized with a common vertical timing signal and further use a common oscillator signal.Type: ApplicationFiled: October 15, 2004Publication date: April 21, 2005Applicant: The Singing Machine Company, Inc.Inventors: Kwok Lau, Kin So

Patent number: 5285700Abstract: A rotor portion of a gas turbine engine comprises two parts which are clamped together by an annular array of bolts. Each bolt head carries a set screw which retains a balancing weight in a position on the bolt head. The balancing weights are so distributed between the bolts as to balance the rotor portion about its axis of rotation.Type: GrantFiled: March 16, 1993Date of Patent: February 15, 1994Assignee: Rolls-Royce plcInventor: Kwok Lau
