Abstract: A type of portable computer with interchangeable components is provided. The chassis of the portable computer includes an upper part, a lower part, and an edge part. The edge part can be equipped with removable input and output (I/O) plates. The motherboards and batteries of this type of portable computer are standardized with or without optional components such as optical drives and/or 2.5 inch hard drives. Motherboards, batteries and other components can be mounted in the chassis of the portable computer through fixed mounting stands and/or removable mounting standoffs. The portable computer allows the I/O plates and/or the edge part to be replaced. Therefore, a motherboard with different I/Os, a motherboard and other components with different heights, and an auxiliary cooling system can be installed in the chassis. In the portable computer, mounting stands and standoffs can be shared by multiple components.

Abstract: A method for authenticating a textile material that is initiated by selecting a unique nucleic acid marker having a specific length and a specific sequence. A media that causes the unique nucleic acid marker to adhere to a fibrous material is then selected. The method then proceeds to generate a nucleic acid marker mixture by mixing the media with the nucleic acid marker. The nucleic acid marker mixture is then applied to the fibrous material. A marked fibrous material is produced by marking the fibrous material with the nucleic acid marker. The textile material is manufactured with the marked fibrous material. The textile material is then authenticated by detecting the unique nucleic acid marker with primers that are specific to the unique nucleic acid. In an alternative embodiment, the media is used as a topical treatment for the fibrous material.

Abstract: A method of marking a solid article or substance includes the steps of dissolving a water-insoluble medium in a first solvent to form a first mixture, mixing a nucleic acid solution with an intermediate solution to form a second mixture, mixing the second mixture with the first mixture to form a homogenous third mixture, marking the article or substance with the third mixture containing the nucleic acid; and drying the marked article or substance. Through the addition of an intermediate solution, the miscibility between the nucleic acid solution and the medium is increased and a homogenous solution is formed. For marking solid substances or articles, the water-insoluble medium containing known nucleic acid taggants is spread on the target solid substances or articles. For marking liquid, the target liquid is mixed with the water-insoluble media containing known nucleic acid taggants. As a result, the target liquid is labeled with nucleic acid.

Abstract: Disclosed are nucleic acid based encryption technique and the corresponding decryption method. The encryption method comprises the steps of dividing an original nucleic acid sequence corresponding to a predefined message according to a predetermined cipher table into a plurality of fragmented nucleic acid sequences, ligating the fragmented nucleotide sequences with oligomers for sequence analysis and oligomers for sequence recognition. The corresponding decryption method comprises the steps of using the corresponding PCR primers and sequencing primers to determine the sequence information of the fragmented nucleotide sequences, combining with the information provided by oligomers for order arrangement to decode the original nucleotide sequence. This multiple encryption method can provide more security to a predefined message desired to keep confidential.

Abstract: The present invention relates to a method of marking solid or liquid substances with nucleic acid for anti-counterfeiting and authentication, specifically to a method for marking solid or liquid substances with nucleic acid dissolved in a water insoluble medium. Through the addition of an intermediate solution, the miscibility between the nucleic acid solution and the medium is increased and forms a homogenous solution. For marking solid substances or articles, the water-insoluble medium containing known nucleic acid taggants is spread on the target solid substances or articles. After drying, nucleic acids protected by the water-insoluble medium adhere on surface of the object. For marking liquid, the target liquid is mixed with the water-insoluble media containing known nucleic acid taggants. As a result, the target liquid is labeled with nucleic acid.

Abstract: This invention features a method of labeling objects for anti-counterfeit purpose, especially refers to a method employing ribonucleic acid for product anti-counterfeit labeling and authenticity verification by PCR method. The procedure involves label objects with medium which contains ribonucleic acid. For verification of authenticity, the medium is removed and extracted for ribonucleic acid which is then amplified by PCR method for comparison.
