Patent number: 9097669Abstract: A known amount of marker may be added to a pressurized hydrocarbon fluid, or combined with an additive to form a mixture, and the mixture may be added to a pressurized hydrocarbon fluid. An amount of the marker in the hydrocarbon fluid may be determined. An amount of the additive in the hydrocarbon fluid may be determined based on the amount of the marker in the pressurized hydrocarbon fluid. An inline system may be used for detection of a marker in a pressurized hydrocarbon fluid. The system is fixed in a pressurized hydrocarbon fluid supply line such that pressurized hydrocarbon fluid flowing from a first location to a second location in the supply line passes through the detection system. The hydrocarbon fluid may be a liquid or a gas. The markers may include a variety of optical markers, such as fluorescent markers. Detection of the markers may include, for example, fluorescence detection.Type: GrantFiled: September 30, 2009Date of Patent: August 4, 2015Assignee: Authentix, Inc.Inventors: Iain Webster, Paul Carr, Ian Eastwood, Ben Weaver, Erwin Dorland, Charles White

Patent number: 8592213Abstract: A first fuel and a second fuel are marked with a marker that can be detected quantitatively in a predetermined concentration range. The second fuel is marked with a binary marker. Decreased concentration of the quantitative marker, presence of a binary marker, or both may be indicative of a fuel that is altered (e.g., mixed, laundered, diluted, or adulterated). Testing a fuel includes testing the fuel for a presence of a first marker in the fuel in a predetermined concentration range, and testing the fuel for a presence of a second marker. The presence of the first marker in the predetermined concentration range and an absence of the second marker may be indicative that the fuel is unaltered. The presence of the first marker in the fuel in a concentration less than the predetermined concentration range or the presence of the second marker may be indicative that the fuel is altered.Type: GrantFiled: April 1, 2011Date of Patent: November 26, 2013Assignee: Authentix, Inc.Inventors: Timothy G. Wilkinson, Erwin Dorland

Patent number: 8354069Abstract: Devices and methods for extraction, identification, authentication, and quantification of one or more covert markers in a material are disclosed. An extraction system includes a first plug flow mixer for mixing a first fluid bearing a marker and transfer agent into a plug flow. The mixing and flowing of the immiscible liquids causes transfer of the marker from the fluid to the transfer agent. A splitter having filters of different surface energies separates the two immiscible liquids, the transfer agent bearing the marker. A second plug flow can be used to transfer the marker to a second transfer agent. The transferred marker is detected to authenticate the original fluid. The marker can be further isolated, activated, or reacted to perform detection, identification or authentication. With the device, a number of independent processing and analytic steps are combined onto a single, portable unit.Type: GrantFiled: July 30, 2008Date of Patent: January 15, 2013Assignee: Authentix, Inc.Inventors: Ian Eastwood, Erwin Dorland, Andrew Taylor

Patent number: 7972859Abstract: A method of determining authenticity of an ingestible product purportedly from a batch of saccharide-marked ingestible product is provided. The ingestible product is a food, beverage, or pharmaceutical, for example. The method includes identifying a sample of the ingestible product to be tested; and testing the sample for a marked presence of the saccharide using a saccharide-specific binding protein. The ingestible product is not authentic when the testing demonstrates an unexpected change in the marked presence of the saccharide, and the ingestible product is authentic when the testing demonstrates no unexpected change in the marked presence of the saccharide.Type: GrantFiled: June 26, 2007Date of Patent: July 5, 2011Assignee: Authentix, Inc.Inventors: Ian Eastwood, Jared Cartwright, Erwin Dorland, Mark Saw

Patent number: 7919325Abstract: The present invention relates to an apparatus and methods for the identification or authentication of liquid products by the addition of an anti-Stokes marker. The invention features an apparatus and method for the identification of a liquid, dynamic or static, that includes adding an anti-Stokes luminescent marker compound to the liquid followed by exposing the compound to a light source of a known wavelength or known wavelengths and then detecting one or more shorter wavelength emissions from the marker, where the identity of the liquid is confirmed by the emission wavelength or wavelengths that are detected and quantified. The irradiating source of light includes, but is not limited to, a laser and other conventional light sources.Type: GrantFiled: May 24, 2004Date of Patent: April 5, 2011Assignee: Authentix, Inc.Inventors: Ian M. Eastwood, Erwin Dorland, Mohammed Salem Al-Jafari, David M. Goodall, Edmund T. Bergstrom

Publication number: 20080118987Abstract: Devices and methods for identification, authentication, and quantification of one or more covert markers in a material are disclosed. A device includes a microfluidic cell, a liquid transfer system, and a detector system and is an integrated unit providing an automated, in-line process for identifying one or more materials containing at least one latent marker that may transform into an active form. The microfluidic cell is for receiving a material containing a latent marker and has at least one inlet for receiving one or more liquids and one or more outlets through which liquids exit. The liquid transfer system is operably connected to the microfluidic cell and delivers liquids to the microfluidic cell. The detector system is proximate to the outlets for detecting the active form of the marker. With the device, a number of independent processing and analytic steps are combined onto a single, portable unit.Type: ApplicationFiled: September 7, 2007Publication date: May 22, 2008Applicant: AUTHENTIX, INC.Inventors: Ian Eastwood, Mohammed Al-Jafari, Erwin Dorland, David Goodall, Edmund T.
