Abstract
Abstract A situational display and a means for creating the display are disclosed. The display comprises a moving line or raster, on a cathode ray tube, which is disposed intermediate of two columns of lamps or intensifications on the cathode ray tube; the raster and lights to either side thereof being controlled in such a manner that pairs of lights define a line which is either tracked or ''''chased'''' by the raster in accordance with the relationship between the optimum and actual values of a monitored parameter.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
191 words
A situational display apparatus for displaying a situation in the real world to a pilot of a pilot-operated aircraft comprising: means for generating a first illuminated indicia which moves at a rate proportional to a desired state of a parameter affecting the real world situation, means for generating a second illuminated indicia, adjacent to said first indicia, which moves a rate proportional to the actual state of said parameter so that the second indicia tracks the first indicia where corrective action is unnecessary and leads or lags the first indicia when the actual state of the parameter differs from the desired state, one of said generating means comprising a plurality of sources of light which, when energized, constitute one of said indicia and which are oriented in parallel columns, and means for energizing pairs of said sources in stepwise manner to define a moving line transverse to said columns; and the other of said generating means comprising at least a portion of a cathode ray tube screen positioned intermediate said columns and providing a movable, substantially linear display parallel to said moving line which display constitutes the other of said indicia.
Claim 2
Dependent Claim
191 words
A situational display apparatus for displaying a situation in the real world to a pilot of a pilot-operated aircraft comprising: means for generating a first illuminated indicia which moves at a rate proportional to a desired state of a parameter affecting the real world situation, means for generating a second illuminated indicia, adjacent to said first indicia, which moves a rate proportional to the actual state of said parameter so that the second indicia tracks the first indicia where corrective action is unnecessary and leads or lags the first indicia when the actual state of the parameter differs from the desired state, one of said generating means comprising a plurality of sources of light which, when energized, constitute one of said indicia and which are oriented in parallel columns, and means for energizing pairs of said sources in stepwise manner to define a moving line transverse to said columns; and the other of said generating means comprising at least a portion of a cathode ray tube screen positioned intermediate said columns and providing a movable, substantially linear display parallel to said moving line which display constitutes the other of said indicia.
Claim 3
Dependent Claim
191 words
A situational display apparatus for displaying a situation in the real world to a pilot of a pilot-operated aircraft comprising: means for generating a first illuminated indicia which moves at a rate proportional to a desired state of a parameter affecting the real world situation, means for generating a second illuminated indicia, adjacent to said first indicia, which moves a rate proportional to the actual state of said parameter so that the second indicia tracks the first indicia where corrective action is unnecessary and leads or lags the first indicia when the actual state of the parameter differs from the desired state, one of said generating means comprising a plurality of sources of light which, when energized, constitute one of said indicia and which are oriented in parallel columns, and means for energizing pairs of said sources in stepwise manner to define a moving line transverse to said columns; and the other of said generating means comprising at least a portion of a cathode ray tube screen positioned intermediate said columns and providing a movable, substantially linear display parallel to said moving line which display constitutes the other of said indicia.
Claim 4
Dependent Claim
191 words
A situational display apparatus for displaying a situation in the real world to a pilot of a pilot-operated aircraft comprising: means for generating a first illuminated indicia which moves at a rate proportional to a desired state of a parameter affecting the real world situation, means for generating a second illuminated indicia, adjacent to said first indicia, which moves a rate proportional to the actual state of said parameter so that the second indicia tracks the first indicia where corrective action is unnecessary and leads or lags the first indicia when the actual state of the parameter differs from the desired state, one of said generating means comprising a plurality of sources of light which, when energized, constitute one of said indicia and which are oriented in parallel columns, and means for energizing pairs of said sources in stepwise manner to define a moving line transverse to said columns; and the other of said generating means comprising at least a portion of a cathode ray tube screen positioned intermediate said columns and providing a movable, substantially linear display parallel to said moving line which display constitutes the other of said indicia.
Claim 5
Dependent Claim
32 words
The apparatus of claim 1 further comprising means for freezing the display provided by the apparatus when the discrepanCy between the actual and desired states of the parameter exceeds a predetermined level.
Claim 6
Dependent Claim
25 words
The apparatus of claim 1 wherein said sources comprise: points on the cathode ray tube defining by intensification of an electron beam in the tube.
