Title: Method and apparatus for using machine vision to detect relative locomotive position on parallel tracks
Inventor: KERNWEIN JEFFREY D
IPC: B61L25/02
Filed: 1999-05-31
Abstract: An automatic train control system, including a track occupancy detector is disclosed which utilizes an image sensor disposed on the front of a locomotive which scans an image immediately in front of the locomotive and is capable of detecting the presence of the occupied track and any parallel tracks disposed on either side of the occupied track. Image processing is accomplished using a Laplacian edge detection algorithm and a Hough transform line detection algorithm. An on-board computer determines the slope of lines corresponding to rails extending ahead of the locomotive. The lines are grouped into lines having positive and negative slope and the number of lines in each group is determined.      Based upon the number of lines having positive and negative slopes, a determination of occupancy is made. The information from the track occupancy detector is provided to other equipment located on the locomotive and used to assist with other advanced train control functions.

Title: Real-time method of digitally altering a video data stream to remove portions of the original image and substitute elements to create a new image
Inventor: STEFFANO MICHAEL D
IPC: G11B27/034
Filed: 1998-03-11
Abstract: A method that allows the real-time replacement of the designated background portion (54) of an incoming video signal with an alternate background (72).  The method utilizes the actual background image for reference (48) as the basis for determining the background and foreground elements within the image with the end result being comparable to traditional blue-screen processes, such as chroma-key and ultimatte technology, but requiring only a personal computer, video camera and the software. In this case, however, the reference background image can be any reasonably static scene with a sufficient and stable light source captured by the camera. The video data stream is modified in real-time by comparisons against the reference background image and is then passed onto its original destination. Multiple signal-noise processing algorithms are applied in real-time against the signal to achieve a visually acceptable matte.

Title: Method and apparatus for drying wood strands
Inventor: GOBEL RICHARD J
IPC: F26B11/02
Filed: 2000-01-05
Abstract: Apparatus (10) for drying particles derived from wood such as sawdust, wafers, flakes, paper sludge, and strands. The wood particles are introduced into a first drying stage (12) and conveyed through a dryer (16) in which the wood particles are heated to an elevated temperature (900°F) to drive off moisture and VOC's from the particles. The wood particles are then delivered to a second drying stage (14) through which they are also conveyed. The particles are now heated to a second elevated temperature (600°F) to substantially eliminate any moisture in the particles so the particles can now be used to make wood products. A heating system includes a combustion chamber (22) to combust fuel to commonly heat the wood particles in both drying stages. The heating system includes a separator (28) for collecting the VOC's driven off from the particles in the first drying stage so the VOC's can be heated in the combustion chamber to a temperature at which they breakdown into shorter chain hydrocarbons which are readily combusted. This substantially eliminates any VOC's which might otherwise be exhausted to the atmosphere.

Abstract: In a telecommunications network, segments along a telecommunications connection causing data corruption or data degradation can be detected and precisely identified through a segment performance monitoring technique. The segment performance monitoring technique involves the generation, transmission, and analysis of specialized data packets which traverse a telecommunications connection node by node. At each node, a value for one or more segment performance characterization factors is accumulated based upon a predefined block of user-assigned data packets. Degradation of the data caused by any segment along the telecommunications connection can be determined, in part, by comparing the value for the one or more segment performance characterization factors to one or more performance characterization factor values generated by a source node.
