Publication number: 20150234980Abstract: According to embodiments of the invention, systems and methods are provided for capturing nucleotide sequence and providing associated modification snapshots with timestamps. The system and/or method are adapted to receive a sample containing a genome sequence from an individual or an organism (hereinafter collectively referred to as a “subject”) that uses the genome for encoding DNA or RNA. The genome sequence is then identified and stored in a database, for access at a later time. Multiple samples from multiple individuals may be taken, analyzed, and compare via the provided invention. Moreover, genetic as well as non-genetic information may be determined and stored in the database. Such information may include data relating to phenotypic features and clinical biological data.Type: ApplicationFiled: February 19, 2014Publication date: August 20, 2015Inventor: Tin Lap LEE

Publication number: 20070249262Abstract: A toy grenade has a container enclosed in a casing consisting of two separable half oval-shaped casings. The container is filled with a mixture of powder and color dye and compressed air. The top of the container is normally retained by a spring biassed elongated rod pressed down by a pivotal handle which is mounted by a removable pull pin. The grenade may be activated by removing the pull pin such that the elongated rod will retract to open the top of the container so that the compressed air will cause two casing halves to separate and the mixture of powder and color dye will spread in the air over the intended target area.Type: ApplicationFiled: April 20, 2006Publication date: October 25, 2007Inventors: See Siu, Kam Hui, Lap Lee

Patent number: 7247997Abstract: A driving circuit for driving an electroluminescent lamp is disclosed. The driving circuit includes an alternating current (AC) voltage generator for providing at an output an AC output voltage waveform for driving an electroluminescent lamp and a controller for controlling the phase and polarity of the AC output voltage waveform. The controller is operable to reverse the phase and polarity of the AC output voltage. In one embodiment, the AC voltage generator includes a transformer.Type: GrantFiled: April 26, 2005Date of Patent: July 24, 2007Inventors: Shing Cheung Chow, Lap Lee Chow, Lap Hang Chow

Patent number: 6963164Abstract: A cold-cathode fluorescent lamp, comprising a sealed lighting enclosure provided with a phosphor coating on at least part of an inner surface thereof the lighting enclosure. An electrode is provided juxtaposed a region of the inner surface of the lighting tube, the electrode energisable from an external source of energy via an electric lead supporting the electrode, and positioned adjacent the main ionisation region within the lighting enclosure. The phosphor is to be excited by radiation to be generated inside the lighting tube by electric discharge from the electrode to provide visible radiation. At least part of the surface(s) of that portion of the electrode proximal most to the ionisation region are overlaid by a cap made from a high heat resistive and non conductive material.Type: GrantFiled: September 15, 2003Date of Patent: November 8, 2005Assignee: Colour Star LimitedInventors: Lap Lee Chow, Lap Hang Chow

Patent number: 6815883Abstract: A cold cathode fluorescent lamp (CCFL) comprises an inner fluorescent tube and an outer glass tube which is sheathed on the outside of said inner tube, characterized in that said inner fluorescent tube and said outer glass tube is separately disposed, and there is a space therebetween. Said CCFL further comprises electrodes sealed at the ends of said inner fluorescent tube and said outer glass tube. The CCFL of the present invention has a double-tube construction, as a result, the inner fluorescent tube is not so much affected by a change in the environmental temperature. Further, the inner fluorescent tube and the outer glass tube are separately disposed so that the end of the inner fluorescent tube and the end of the outer glass tube are not integrally joined, so that a rate of the breakage caused by the temperature difference between two ends is dramatically reduced.Type: GrantFiled: September 26, 2002Date of Patent: November 9, 2004Assignees: Dongguan Nam Kwong Electric Co., Ltd.Inventors: Shing Cheung Chow, Lap Lee Chow
