Abstract
Abstract A method and apparatus for entering data in a random access memory with a fixed orientation independent of the heading vector of the carrier vehicle. The data remains positionally fixed in the memory and is addressed for readout in a manner to present a heading-up display for all vehicle heading vectors.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
183 words
A method for presenting data from a sensor on a vehicle moving along vector tracks comprising the steps of: receiving data in coordinates of a first coordinate system; converting data coordinates in said first coordinate system to data coordinates in a second coordinate system; storing converted data in a memory having data storage locations arranged to represent said second coordinate system; entering initial position coordinates of said vehicle in said second coordiante system in an initial position coordinate memory; entering coordinate incremental fractions for said second coordinate system in incremental fraction memories, said incremental fractions selected to establish lines originating at said vehicle position along which data is stored in said memory; adding said coordinate fractions in an accumulating manner to said initial position after a data entry at a data coordinate to establish a subsequent data coordinate for data entry; addressing said memory to read out data along parallels to said vector tracks in said second coordinate system; and displaying said read out data along parallels to said vector tracks on a display whereon said vector tracks have a common predetermined orientation.
Claim 2
Independent Claim
183 words
A method for presenting data from a sensor on a vehicle moving along vector tracks comprising the steps of: receiving data in coordinates of a first coordinate system; converting data coordinates in said first coordinate system to data coordinates in a second coordinate system; storing converted data in a memory having data storage locations arranged to represent said second coordinate system; entering initial position coordinates of said vehicle in said second coordiante system in an initial position coordinate memory; entering coordinate incremental fractions for said second coordinate system in incremental fraction memories, said incremental fractions selected to establish lines originating at said vehicle position along which data is stored in said memory; adding said coordinate fractions in an accumulating manner to said initial position after a data entry at a data coordinate to establish a subsequent data coordinate for data entry; addressing said memory to read out data along parallels to said vector tracks in said second coordinate system; and displaying said read out data along parallels to said vector tracks on a display whereon said vector tracks have a common predetermined orientation.
Claim 3
Dependent Claim
172 words
A method for presenting data in accordance with claim 1 wherein the step of addressing said memory includes: establishing a base line, in said second coordinate system, through said vehicle initial position coordinates perpendicular to said vehicle track; establishing origin coordinates on said base line, in said second coordinate system, a predetermined distance from said vehicle initial coordinates position whereat an initial raster line originates; entering said origin coordinates in said initial coordinate memory entering coordinate fractions, selected to establish raster lines parallel to said vehicle track, in said coordinate fraction memory; adding said coordinate fractions to said initial position coordinates to establish address codes to said memory; incrementing said origin position coordinates of said initial raster line to establish origin position coordinates on said base line for subsequent raster lines; and adding said coordinate fractions to said origin coordinates of said subsequent raster lines to provide address codes to said memory along lines in said second coordinate system that are parallel to a data line corresponding to said initial raster line.
Claim 4
Dependent Claim
27 words
A method in accordance with claim 1 wherein said first coordinate system is a polar coordinate system and said second coordinate system is a rectangular coordinate system.
Claim 5
Dependent Claim
41 words
A method in accordance with claim 3 wherein said display is in an X-Y coordinate system having x and y axes and said vectored track presentation is a line perpendicular to said x-axis of said display, thereby establishing a track-up display.
Claim 6
Dependent Claim
43 words
A method for displaying data in accordance with claim 1 wherein said addressing step includes addressing said memory with counters that rollover upon reaching a maximum count, and a boundary of said memory, to address said memory commencing with a first memory stage.
Claim 7
Dependent Claim
84 words
A method for displaying data in accordance with claim 2 wherein said storing step includes entering zero data along said baseline from initial position coordinates memory cells to a first data boundary at a conclusion of a first data entry period, and entering zero data along said baseline from said initial position coordinate memory cells to a second data boundary, at coordinates diametrically opposite said first data boundary, at a conclusion of a second data entry period next following said first data entry period.
Claim 8
Independent Claim
136 words
