Abstract
Abstract A method and apparatus for producing a video display that is especially useful in an article handling system to help control a mechanical arm to move an article into a selected position. A video camera is operated to produce a picture of the article on a video screen. At the same time, force sensor are used to measure forces on the article, and a graphical display of those sensed forces is produced on the view of the article on the video screen.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
83 words
A display apparatus comprising: means to produce a view of an article on a display screen for a period of time; means to measure, at least at a multitude of times during said period, forces applied to the article during said period; and graphical display means to impose on said view and during said period, a graphical display illustrating the measured forces, and including means to represent in the graphical display each of the measured forces at a respective time during said period.
Claim 2
Dependent Claim
83 words
A display apparatus comprising: means to produce a view of an article on a display screen for a period of time; means to measure, at least at a multitude of times during said period, forces applied to the article during said period; and graphical display means to impose on said view and during said period, a graphical display illustrating the measured forces, and including means to represent in the graphical display each of the measured forces at a respective time during said period.
Claim 3
Dependent Claim
83 words
Display apparatus according to claim 1, wherein the graphical display means includes: means to produce a graphical frame on the display screen and to maintain the graphical frame in a fixed position thereon relative to the view of the article; and means to produce a multitude of graphical images on the display screen, each of the graphical images representing a respective one of the measured forces and being shown on the screen substantially at the same time said respective one force is measured.
Claim 4
Dependent Claim
125 words
Display apparatus according to claim 2, wherein: the measured forces each include first, second, and third mutually orthogonal components; the graphical frame includes a two-dimensional view of three mutually orthogonal axes; and the means to produce the graphical images is adapted to produce i) a first, variable length bar along a first of said axes to represent the magnitude of the first component of the forces applied to the article, ii) a second, variable length bar along a second of said axes to represent the magnitude of the second component of the forces applied to the article, and iii) a third, variable length bar along a third of said axes to represent the magnitude of the third component of the forces applied to the article.
Claim 5
Independent Claim
66 words
A method of moving an article into a selected position, comprising: operating a video camera to produce a picture on a video screen showing both the article and the selected position; moving the article toward and into the selected position; sensing a force applied to the article; and graphically displaying on the video screen the sensed force as the article is moved into the selected position.
Claim 6
Independent Claim
66 words
A method of moving an article into a selected position, comprising: operating a video camera to produce a picture on a video screen showing both the article and the selected position; moving the article toward and into the selected position; sensing a force applied to the article; and graphically displaying on the video screen the sensed force as the article is moved into the selected position.
Claim 7
Dependent Claim
26 words
A method according to claim 4, wherein the selected position is adjacent a surface, and said force is a force between the article and the surface.
Claim 8
Dependent Claim
121 words
Apparatus for moving an article into a selected position, comprising: a moveable mechanical arm; arm control means connected to the mechanical arm to operate the arm to grip the article and to carry the article into the selected position; video display means; a video camera located adjacent the article and connected to the video display means to produce a picture thereon showing both the article and the selected position; sensing means to sense a force on the article and to generate a signal indicating the magnitude of the sensed force; and graphical display means connected to the sensing means to receive said signal therefrom, and connected to the video display means to generate thereon a graphical display of the sensed force.
Claim 9
Dependent Claim
121 words
Apparatus for moving an article into a selected position, comprising: a moveable mechanical arm; arm control means connected to the mechanical arm to operate the arm to grip the article and to carry the article into the selected position; video display means; a video camera located adjacent the article and connected to the video display means to produce a picture thereon showing both the article and the selected position; sensing means to sense a force on the article and to generate a signal indicating the magnitude of the sensed force; and graphical display means connected to the sensing means to receive said signal therefrom, and connected to the video display means to generate thereon a graphical display of the sensed force.
Claim 10
Dependent Claim
45 words
Apparatus according to claim 6, wherein: said force includes first, second, and third mutually orthogonal components; and the graphical display means includes means to generate on the video display means a graphical display illustrating the magnitude of each of said first, second, and third components.
