Abstract
Abstract A system that utilizes a light pen for changing the alphanumeric value of certain information that is displayed on the screen of a cathode ray tube. Certain parameters and their alphanumeric values are displayed on the CRT screens. A row of dots or other characters are drawn on the CRT screens next to the listed parameters. When the operator of this invention touches one of the dots or other characters with a light pen, the parameters next to the dots or characters will be identified and the alphanumeric value of that parameter will be either incremented or decremented at a fast or slow rate, depending upon the position of the dot in the array. Various types of arrays may be utilized.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
253 words
A computer controlled display system that is coupled to an instructor's station in a training simulator for changing the alphanumeric value of information that appears on the screen of a display system, said system comprising: at least one display device that displays alphanumeric characters, symbols and geometric shapes on its screen, the information displayed on the screen of the display device is arranged such that a plurality of geometric shapes are displayed in a position related to a group of alphanumeric characters and/or symbols that represent a parameter and its value; display generating means for causing information to be displayed on the screen of said display device at predetermined locations, said display generating means being coupled to said display device; at least one light pen coupled to said generating means and capable of touching the geometric shapes that appear on the screen of said display device; and a computer that contains a list of alphanumeric characters and symbols and a series of mathematical relationships that permit the value of the displayed parameter to be in the memory of said computer and on the screen of said display changed at predetermined rates, whereby, when said light pen is placed against one of said geometric shapes, the value of one of said displayed parameters is changed at one rate in the memory of said computer and on the screen of said display device and when said light pen is placed against another one of said geometric shapes, said value is changed at a different rate.

A computer controlled display system that is coupled to an instructor's station in a training simulator for changing the alphanumeric value of information that appears on the screen of a display system, said system comprising: at least one display device that displays alphanumeric characters, symbols and geometric shapes on its screen, the information displayed on the screen of the display device is arranged such that a plurality of geometric shapes are displayed in a position related to a group of alphanumeric characters and/or symbols that represent a parameter and its value; display generating means for causing information to be displayed on the screen of said display device at predetermined locations, said display generating means being coupled to said display device; at least one light pen coupled to said generating means and capable of touching the geometric shapes that appear on the screen of said display device; and a computer that contains a list of alphanumeric characters and symbols and a series of mathematical relationships that permit the value of the displayed parameter to be in the memory of said computer and on the screen of said display changed at predetermined rates, whereby, when said light pen is placed against one of said geometric shapes, the value of one of said displayed parameters is changed at one rate in the memory of said computer and on the screen of said display device and when said light pen is placed against another one of said geometric shapes, said value is changed at a different rate.
Claim 3
Dependent Claim
14 words
The system defined in claim 1 wherein said display is a cathode ray tube.
Claim 4
Dependent Claim
14 words
The system defined in claim 1 wherein said display device is a digital television.
Claim 5
Dependent Claim
12 words
The system defined in claim 1 wherein said geometric shapes are dots.
Claim 6
Dependent Claim
47 words
The systems defined in claim 4 wherein said dots are arranged in two rows, where one row of dots will be used only for increasing the value of said parameter and the other row of dots will be used only for decreasing the value of said parameter.
Claim 7
Dependent Claim
27 words
The system defined in claim 5 wherein each of said dots represents a different rate in which the value of said parameter will be increased or decreased.
Claim 8
Dependent Claim
214 words
A computer controlled display system that is coupled to an instructor's station in a training simulator for modifying the alphanumeric value of information that appears on the screen of a display system, said system comprising: at least one display device that displays alphanumeric characters, symbols and geometric shapes on its screen, the information displayed on the screen of the display device is arranged such that a predetermined number of geometric shapes are displayed next to or in a position related to a group of alphanumeric characters and/or symbols that represent a parameter and its value; display generating means for causing information to be displayed on the screen of said display device at certain specified and predetermined locations, said display generating means being coupled to said display device; at least one touch-sensitive digitizer; and a computer that contains a list of alphanumeric characters and symbols and a series of mathematical relationships that permit the value of the displayed parameter to be modified at predetermined rates that are different for each of said geometric shapes, whereby, when one of said geometric shapes on said digitizer is touched by the operator the value of one of said displayed parameters is modified at one rate in the memory of said computer and on the screen of said display.
