Abstract: A technique for simplifying structure data for representing an environment. Polyhedrons can make up structure data used in an application such as modeling, visualization, and navigation. Consequently, the operations that are performed on the data often involve determining, for each polyhedron that defines a structure such as a building, whether the polyhedron obstructs a line-of-sight line between a first point in space being considered in the application and a second point. In order to determine whether a polyhedron obstructs a line-of-sight line, a data-processing system operating on the structure data must determine whether any walls of the polyhedron intersect the line. Thus, the more polyhedrons there are or the more vertices that are in each polyhedron, the more walls there are, and the more intersection checks are required, thereby adding to the computations. The disclosed technique reduces the number of walls by simplifying objects that make up the structure data.

Abstract: A location engine that estimates the barometric pressure measurement bias of a wireless terminal, resulting in an improved estimate of elevation of the wireless terminal. The location engine generates an estimate of measurement bias by comparing the barometric pressure measured by the wireless terminal while at that elevation and the barometric pressure that corresponds to an estimated elevation of the wireless terminal when it made the pressure measurement (i.e., the expected pressure). The estimated elevation is based on an inferred above-ground height and the local terrain elevation, and the expected pressure is based on the measurement of barometric pressure at the pressure reference and the estimated elevation. The location engine infers the height based on various techniques disclosed herein. The location engine can use the measurement bias to adjust subsequent pressure measurements reported by the wireless terminal, in order to generate an improved estimate of elevation of the wireless terminal.

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 route generator and method of operating the same including; calculating route traversal values for a plurality of blocks in a first group simultaneously, each block including a plurality of cells, traversal values being values that consider terrain movement cost data and data indicating progress towards a route endpoint on a per-cell basis, wherein the plurality of blocks are chosen such that the blocks in the first group fail to share any edges with other blocks in the first group.

Abstract: A snowmobile has an air intake system integrated into the snowmobile body, and with air intake vents facing rearwardly towards the rider. The air intake system includes a plenum defined by a portion of the body and ducting extending within the body. The ducting is porous to allow the air input noise to be dissipated within the engine compartment. The snowmobile further comprises couplings which may be realigned to accommodate wear. A frame coupler allows multiple differently configured frame tubes to be connected to the tunnel. The chassis of the snowmobile includes a casing for receiving the gears which drive the belt.

The jump seat comprises a seat back which is positioned rearwardly of the rear seats, and the rear seats are movable laterally between a first position where the rear seats are proximate to each other and generally covering the seat back of the jump seat, and a second position where the rear seats are spaced apart from each other and the seat back of the jump seat is exposed. The arrangement may also include rear seats which are rotatable relative to the seat backs to provide a storage surface.

Abstract: A computer-implemented system and method distilling three-dimensional structure to a two-dimensional raster with multiple discrete planes for purposes of safe and accurate route planning including a map generator (100), pixel encoder (102), map transformer (106), and route generator (108). The map generator (100) generates a raster map by populating a blank map canvas with raster and vector data on a per-pixel basis and obtains values for pixels from the pixel encoder (102). The pixel encoder (102) encodes type, plane, and elevator information of features into pixels. The map transformer (106) converts the map produced by the map generator (100) into a weighted graph of nodes and edges suitable for route generation. The route generator (108) generates routes using the graph produced by the map transformer (106).
