    Abstract: In a method of determining the position of an object, raw image data of the sky is recorded using a celestial imaging unit. The last known position, orientation, date, and time data of the object are obtained, and the position of a celestial body is measured. A latitude and longitude of the object is determined by matching the measured celestial body position to the expected celestial body position based on the input parameters. A system for determining a new position of an object comprises a celestial imaging unit configured to record image data of the sky, a signal processing unit, and a signal processing unit configured to receive and store in memory the image data received from the celestial imaging unit. The signal processing unit filters the image to find the positions of celestial objects in the sky. The signal processing unit is further configured to use roll and pitch from an IMU, and date and time from a clock to determine the object's position (latitude and longitude).

    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.

    Abstract: A method using Long Wave Infrared Imaging Polarimetry for improved mapping and perception of a roadway or path and for perceiving or detecting obstacles comprises recording raw image data using a polarimeter to obtain polarized images of the roadway or area. The images are then corrected for non-uniformity, optical distortion, and registration. IR and polarization data products are computed, and the resultant data products are converted to a multi-dimensional data set for exploitation. Contrast enhancement algorithms are applied to the multi-dimensional imagery to form enhanced object images. The enhanced object images may then be displayed to a user, and/or an annunciator may announce the presence of an object. Further, the vehicle may take evasive action based upon the presence of an object in the roadway.

    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.
