Title: Digitizer with serpentine conductor grid having non-uniform repeat increment
Inventor: MCDERMOTT ROBERT M
IPC: G06F3/0488
Filed: 1991-04-05
Abstract: ABSTRACT OF THE DISCLOSURE       Disclosed herein are position determining apparatus and conductor structures or grids therefor.  The conductor structure for each axis includes a number of conductors, at least one of which is run in a serpentine path with a non-uniform repeat in-crement.  The repeat increment, which is the spacing between one run and the next of the same serpentine conductor, is constrained by a maximum repeat increment, or a minimum repeat increment, or a maximum change in repeat increments between consecutive runs of a same conductor, or combinations thereof.  In the preferred em-bodiments, there is at least a constraint on the maximum repeat increment to provide noise immunity.  The conductors are arranged for each axis of the grid in a pattern such that signals obtained for that axis may be processed to provide binary numbers in a Gray-type code each unique to a small region of the active area in which the coil center is located.  The small region for a given axis corresponds to the space between two immediately ad-jacent, active conductor portions for that axis, with a possible ambiguity of one space.  Small regions in each axis define the coarse location of the coil center.  Fine location within a region may be determined from the magnitudes of currents induced in selected runs by interpolation, or from the phase relationship of current induced in selected runs.

Title: Method for analyzing feasibility in a schedule analysis decision support system
Inventor: HARKER PATRICK T
IPC: G06Q10/06
Filed: 1991-07-12
Abstract: ABSTRACT A method of analyzing transportation schedules in a schedule analysis (SCAN) decision support system to determine the feasibility of the schedules is disclosed. In a transportation system, vehicles are delayed to avoid conflicts with other vehicles which would otherwise collide because the vehicles may be travelling along the same travel paths at different speeds or in opposite directions. The invention utilizes information relating to the vehicle travel paths, the vehicle's speed and mobility characteristics, a function based on the vehicle's on-time performance, proposed transportation schedules and real-time data associated with the travel paths and vehicles. This information is used to provide substantially optimal vehicle schedules with respect to cost resulting from vehicle delay.

IPC: G06T7/20
Filed: 1991-09-06
Abstract: MOVING TARGET DETECTION METHOD USING        TWO-FRAME SUBTRACTION ABSTRACT OF THE DISCLOSURE A method and apparatus for detecting an object of interest against a cluttered background scene.  In a first preferred embodiment the sensor tracking the scene is movable on a platform such that each frame of the video representation of the scene is aligned,  i.e., appears at the same place in sensor coordinates.   A current video frame of the scene is stored in a first frame storage device (14) and a previous video frame of the scene is stored in a second frame storage device (20).   The frames are then subtracted by means of an invertor (24) and a frame adder (28) to remove most of the background clutter.   The subtracted image is put through a first leakage reducing filter, preferably a minimum difference processor filter (32).  The current video frame in the first frame storage device (14) is put through a second leakage-reducing filter, preferably minimum difference processor filter (36).  The outputs of the two processors are applied to a two quadrant multiplier  (42)  to minimize the remaining background clutter leakage and to isolate the moving object of interest. In a second preferred embodiment the sensor does not track the scene and therefore the frames of video from the two storage devices (140, 200) must be aligned before the subtraction process can occur.  The alignment  function  is  performed  by  a  background registration correlator (150) and a frame shifter (130). Once the two frames of video data are aligned they are then subtracted and preferably applied to the minimum difference processor filters  (320,  360)  as with the first  embodiment.   The  outputs  of the  two minimum difference processors (320, 360) are again applied to a two quadrant multiplier (420) to eliminate the remaining background clutter.
