Abstract: A smoke producing method and device of the present disclosure produces a non-incendiary, organic-polymerization based, smoke-producing reaction. The method 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 determining a new orientation and/or position of an object comprises a sky polarimeter configured to record image data of the sky, a signal processing unit, and logic configured to receive and store in memory the image data received from the sky polarimeter. The logic calculates the Stokes parameters (S0, S1, S2,), DoLP, and AoP from the image data, detects obscurants and filters the obscurants (such as clouds and trees) from the image data to produce a filtered image. The logic is further configured to find the Sun and zenith in the filtered image, and to determine the roll, pitch, yaw, latitude and longitude of the object using the filtered image. A method for determining a new position/orientation of an object comprises recording raw image data using a sky polarimeter, calculating S0, S1, S2, DoLP, and AoP from the image data, detecting obscurants and filtering the obscurants from the image data to produce a filtered image, obtaining last known position/orientation data of the object, finding the Sun and zenith in the filtered image, and determining the roll, pitch, yaw, latitude and longitude of the object using the filtered image.

Abstract: A system for confirming the detection of a fire using a plurality of radiation or flame sensors each equipped with a radiation detector and an optical filter having a spectral transmission characteristic in which at least one optical filter is redundant to at least one other optical filter. The result is a system having operationally redundant sensors. In use, if a fire is detected by one of the redundant sensors without including the other redundant radiation sensor in the fire detection calculation, then a fire detection algorithm can switch to the other operationally redundant sensor to check for confirmation of a fire. Due to the spatial separation and if the object is small and close, a different result will be obtained with the redundant detector being used in the calculation compared to the primary detector that is associated with the redundant detector.

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. A 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 Moiré effects resulting from the use of two displays. In one embodiment, the light spreading device is a diffuser. In another embodiment, the light spreading device is a micro lens array.

Abstract: A method for enhancing an image for facial recognition comprises capturing an image of the face with a polarizer and correcting the polarized image for non-uniformity. Stokes Parameters S0, S1, S2 are obtained by weighted subtraction of the polarized image to form Stokes images. DoLP is computed from the Stokes images, and facial recognition algorithms are applied to the DoLP image. A system for enhancing images for facial recognition comprises a polarimeter configured to record polarized image data of a subject's face, a signal processing unit and logic configured to receive and store in memory the image data from the polarimeter, calculate Stokes parameters from the image data, and compute a DoLP image from the Stokes parameters.

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: 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).
