  • System And Method For The Excitation, Interrogation, And Identification Of Covert Taggants
    Publication number: 20120104278
    Abstract: Apparatuses and methods relating to excitation, interrogation, and identification of covert taggants, are described. In one exemplary embodiment, a multi-measurement interrogator comprising an emitter and an optical sensing subsystem that is capable to sense more than one type of a response signal from a taggant is described. The multi-measurement interrogator may interrogate the taggant multiple excitation wavelengths, acquire more than one type of the response signal from the taggant, and perform quantitative measurements of the response signal. Another exemplary embodiment of the invention describes an eye-safe interrogator that includes a light emitting diode (LED), wherein LED is capable to stimulate one or more of an upconversion fluorescence and a Stoke's fluorescence from the taggant. Another exemplary embodiment of the invention provides a portable, hand-held covert interrogator, which utilizes invisible light both to excite the taggant and to receive a response from the taggant.

  • Head-set display device
    Patent number: 6034653
    Abstract: The invention relates to a display head-set device that includes a support member and a display-optics interface pod coupled to one of a left handle portion and a right handle portion of the support member. The display-optics interface pod houses an image display for viewing by a user. In one embodiment, the display head-set resembles a pair of eye glasses with the interface pod attached to one of the left handle portion and the right handle portion of the support member by an arm clip and extending into the field of vision to offer a monocular viewing sight to the user.
