Patent number: 9869636Abstract: A portable, tabletop fluid sampling device simplifies spectral analysis to produce an accurate but inexpensive chromatic fingerprint for fluid samples. In one embodiment, the sampling device uses an array of variable wavelength LED emitters and photodiode detectors to measure Rayleigh scattering of electromagnetic energy from the fluid sample contained in a cuvette. Either the fluid itself, or particles suspended in the fluid can then be identified by performing spectral pattern matching to compare results of a spectral scan against a library of known spectra. A wide range of applications include substance identification, security screening, authentication, quality control, and medical diagnostics.Type: GrantFiled: May 22, 2015Date of Patent: January 16, 2018Assignee: Visualant, Inc.Inventors: Richard Ian Mander, Allan David Beach, Michael Vivian Denton, Thomas A.

Patent number: 8888207Abstract: A system employs combinations of marking media, each with respective distinguishing spectral characteristics to encode human comprehensible information in, and read human comprehensible information from, machine-readable indicia or symbols. Machine-readable indicia may be a single dot encoding information only in the combinations. Machine-readable symbols may be linear or two dimensional, spatially encoding information in the combinations, as well as spatially. A symbology may map at least the combinations to human-readable symbols or characters. A printer may form indicia or symbols with combinations of marking media. A reader may read indicia or symbols and decode information from at least the combinations of marking media. Different combinations may be visually homogenous, for example gray.Type: GrantFiled: February 7, 2013Date of Patent: November 18, 2014Assignee: Visualant, Inc.Inventors: Thomas A.

Publication number: 20140203184Abstract: An apparatus employs a plurality of transducers distributed along a cable to sample a medium. Some of the transducers may be operated according to various sequences which specific wavelengths and/or magnitudes of emission of electromagnetic energy. Some of the transducers sample, detect or measure responses of the fluid medium to the emissions. Various other transducers may sample or measure temperature, depth or pressure, and flow characteristics of the fluid medium, and optionally flow characteristics above a surface or above a surface of the fluid medium. Such may allow identification and/or characterization of characteristics of the fluid medium and/or substances (e.g., contaminants for instance petroleum, phytoplankton, red tide microorganisms, nutrients, dissolved oxygen or other gasses). The apparatus may communicate with remote facilities, allowing monitoring, remote control, and/or analysis with or with information from other platforms.Type: ApplicationFiled: March 24, 2014Publication date: July 24, 2014Applicant: Visualant, Inc.Inventors: Peter Kevin Purdy, Matthew Creedican, Brian T.

Publication number: 20140063239Abstract: A spectral analysis surveillance system includes sources or emitters which emit various wavelengths of electromagnetic radiation or energy into a space under surveillance, and a sensor which produce signals indicative of electromagnetic energy returned by people and other objects in the space. The electromagnetic radiation may fall in the visible portion of the electromagnetic spectrum yet the energy is emitted to appear as either white light or a single color. Returned energy is analyzed against reference samples. The spectral analysis surveillance system may be part of an integrated surveillance system including other components, for example metal detectors, baggage X-ray scanners, full body imagers, etc., and may provide surveillance of private or public locations, for instance airports.Type: ApplicationFiled: February 7, 2013Publication date: March 6, 2014Applicant: Visualant, Inc.Inventor: Visualant, Inc.
