The system comprises memory and logic for monitoring traffic intersections and recording evidence indicating that vehicles; have violated pedestrian right of way. Two sensor modalities collecting video data and radar data of the intersection; under observation are employed in one embodiment of the system. The violation, evidence can be accessed remotely by a traffic official for issuing of traffic citations.
Abstract:
A smoke producing method and device of the present disclosure produces a non-incendiary, organic-polymerization based, smoke-producing reaction. The limited of generating smoke comprises Initiating a frontal polymerization reaction by heating a composition comprising a monomer compound that exothermically polymerizes upon initiation with an initiator compound and an initiator compound that initiates polymerization of the monomer compound present at a mass concentration that is at least five percent of the mass concentration of the monomer compound. The polymerization of the monomer compound is exothermic, and in one embodiment the concentration of initiator compound is at least five percent of the concentration of monomer compound. The smoke mainly comprises thermal decomposition products of the initiator compound.
Abstract:
A system for display of three dimensional images and video utilizing flat panel technology, such as liquid crystal technology, wherein the left and right images are separated by polarization and the user wears polarized glasses to view the display. A first display, which may be any display technology, is used to generate an intensity modulated image. The second display is used to modulate the polarization of the intensity modulated image. A light spreading device is used to spread the light to minimize Moir- effects resulting from the use of two displays. In one embodiment the light spreader is a diffuser. In another embodiment, the light spreader is a micro lens array.
Abstract:
A method for detecting the presence of foreign fluids on surface comprises estimating an expected polarization response for a foreign fluid desired to be detected. Oil from an oil spill is one such foreign fluid. A polarimeter records raw image data of a surface (e.g., the surface of water) to obtain polarized images of the surface. IR and polarization data products are computed from the polarized images. The IR and polarization data products are converted to multi-dimensional data set to form multi-dimensional imagery. Contrast algorithms are applied to the multi-dimensional imagery to form enhanced contrast images, from which foreign fluids can be automatically detected.

Abstract:
A pesticide application method and device of the present disclosure produces a non-incendiary, organic-polymerization based pesticide smoke producing reaction. The smoke mainly comprises pesticide and reaction products of the initiator compound. A composition for the non-pyrotechnic generation of pesticide-containing smoke is provided that includes an initiator, and a pesticide agent. Some versions of the composition also include a monomer that polymerizes exothermically. A non-pyrotechnic method of generating pesticide-containing smoke is provided, which includes initiating a frontal reaction (FR) in a composition for the non-pyrotechnic generation of pesticide-containing smoke, and generating smoke comprising the pesticide agent. A method of applying a pesticide to an area is provided, involving initiating an FR to generate pesticide-containing smoke, and exposing the area to the smoke for a period of time sufficient to kill pests. A non-pyrotechnic smoke generator for generating a pesticide-containing smoke is provided, including the smoke-generating composition and an initiation source.

Abstract:
A method using Infrared Imaging Polarimetry for detecting the presence of foreign fluids on water comprises estimating an expected polarization response for a foreign fluid desired to be detected. Oil from an oil spill is one such foreign fluid. An optimal position of a polarimeter to take images of the water's surface is determined from the expected polarization response. The polarimeter is positioned at the optimal position and records raw image data of the water's surface to obtain polarized images of the area. The polarized images are corrected, and IR and polarization data products are computed. The IR and polarization data products are converted to multi-dimensional data set to form multi-dimensional imagery. Contrast algorithms are applied to the multi-dimensional imagery to form enhanced contrast images, from which foreign fluids can be automatically detected.
