Patent number: 8501481Abstract: A system and method for tagging, tracking, locating and identifying people and vehicles transporting people using Perfluorocarbon tracers. An on-going problem faced by military as well as law enforcement personnel is that of friendly fire incidents. To prevent possible friendly-fire incidents, troops would separate the two layers of the uniform patch, thereby releasing a controlled release of the Perfluorocarbon vapors. Other “friendly” troops, equipped with sensors tuned to the specific perfluorocarbon characteristics would thus be able to literally view a plume around the tagged person or object. The system may conversely be used to tag enemies. Formulations of mixed perfluorocarbons may be used to provide coding of emissions.Type: GrantFiled: April 9, 2012Date of Patent: August 6, 2013Assignee: Tracer Detection Technology Corp.Inventor: Jay Fraser

Patent number: 6025200Abstract: A method of tagging and detecting objects is disclosed which comprises the steps of: (a) applying a volatile taggant to the object; and (b) subsequently detecting the presence of the taggant by the absorption, transmittance, reflectance, photon emission or fluorescence of the taggant and therefore a proximity of the tagged object. The present invention therefore provides optical sensing means which do not require physical separation of differing compounds for discrimination thereof.Type: GrantFiled: December 21, 1996Date of Patent: February 15, 2000Assignee: Tracer Detection Technology Corp.Inventors: Norman Kaish, Jay Fraser, Volkan Otugen, Svetozar Popovic

Patent number: 5974150Abstract: An authentication system comprising a medium having a plurality of elements, the elements being distinctive, detectable and disposed in an irregular pattern or having an intrinsic irregularity. Each element is characterized by a determinable attribute distinct from a two-dimensional coordinate representation of simple optical absorption or simple optical reflection intensity. An attribute and position of the plurality of elements, with respect to a positional reference is detected. A processor generates an encrypted message including at least a portion of the attribute and position of the plurality of elements. The encrypted message is recorded in physical association with the medium. The elements are preferably dichroic fibers, and the attribute is preferably a polarization or dichroic axis, which may vary over the length of a fiber.Type: GrantFiled: July 6, 1998Date of Patent: October 26, 1999Assignee: Tracer Detection Technology Corp.Inventors: Norman Kaish, Jay Fraser, David I.
