Patent number: 8957124Abstract: A laser can be used to modify a glazing 100, 300 so as to improve its suitability for use with a signal-receiving device 350 or a signal-transmitting device 350. This is done by using the laser to provide a region of reduced opacity 110, 202, 340 to the signal within the glazing. Preferably, the laser is be used to reduce the opacity of a selected region 340 of a tinted interlayer in situ. The glazing may be for a vehicle, especially an automotive vehicle.Type: GrantFiled: January 6, 2006Date of Patent: February 17, 2015Assignee: Pilkington Group LimitedInventors: Michael Lyon, Michael Robert Greenall

Publication number: 20140256881Abstract: The invention provides methods for stably binding and immobilizing deoxyribonucleic acid onto objects and substrates. The method includes exposing the deoxyribonucleic acid to alkaline conditions, and contacting the deoxyribonucleic acid to the object or substrate. The alkaline conditions are produced by mixing the deoxyribonucleic acid with an alkaline solution having a pH of about 9.0 or higher, and contacting the deoxyribonucleic acid to the substrate. The immobilized DNA can be used as a taggant and can be used in combination with other detectable taggants, such as optical reporters. Methods for authentication of a DNA marked object are also provided.Type: ApplicationFiled: March 7, 2013Publication date: September 11, 2014Applicant: APPLIED DNA SCIENCES, INC.Inventor: APPLIED DNA SCIENCES, INC.
