Abstract
Abstract A method and apparatus therefor for providing an individual a magnified view of the manual manipulations of the individual, particularly those of a surgeon during surgery. Video cameras are provided for viewing the manual manipulations of the individual. Electric signals representing an image of the manual manipulations are transmitted to a video screen placed in optical alignment with eyes of the individual. The image viewed by the individual is selectively magnified and focused by the individual. An image other than that of manual manipulations of the individual can be transmitted to and projected on the video screen to provide the individual with additional visual information.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
139 words
A method of selectively providing an individual a magnified view of an image of manual manipulation of the individual and images of other than the manual manipulation of the individual, the method comprising: (a) viewing the manual manipulation by means of a video camera; (b) generating electrical signals by a first signal generating means representing a first image of said manual manipulation; (c) viewing a second image spaced from said manual manipulation by a second video camera; (d) generating electrical signals representing the second image by a second signal generating means; (e) positioning a viewing means in optical alignment with eyes of said individual; (f) signal transmittingly connected said viewing means with said first and second signal generating means; and (g) selectively regenerating by a signal selection means one of said first or second images on said viewing screen.
Claim 2
Independent Claim
139 words
A method of selectively providing an individual a magnified view of an image of manual manipulation of the individual and images of other than the manual manipulation of the individual, the method comprising: (a) viewing the manual manipulation by means of a video camera; (b) generating electrical signals by a first signal generating means representing a first image of said manual manipulation; (c) viewing a second image spaced from said manual manipulation by a second video camera; (d) generating electrical signals representing the second image by a second signal generating means; (e) positioning a viewing means in optical alignment with eyes of said individual; (f) signal transmittingly connected said viewing means with said first and second signal generating means; and (g) selectively regenerating by a signal selection means one of said first or second images on said viewing screen.
Claim 3
Dependent Claim
23 words
The method as set forth in claim 1 including the step of: (a) selectively magnifying said first image by image magnification adjustment means.
Claim 4
Dependent Claim
32 words
The method as set forth in claim 2 including the step of: (a) positioning said magnification adjustment means in close proximity to said individual so as to be manipulable by said individual.
Claim 5
Independent Claim
102 words
A method of providing a magnified view of manual manipulation of an individual to that individual comprising the steps of: (a) viewing the manual manipulation by image transmitting means; (b) generating electrical signals representing an image of said manual manipulations; (c) positioning a first viewing means in optical alignment with said individual; (d) regenerating said image on said first viewing means; (e) selectively magnifying by magnification adjustment means the image regenerated on said first viewing means; and (f) placing said image transmitting means and said first viewing means in a unitary housing adapted to be worn on the head of the individual.
Claim 6
Independent Claim
102 words
A method of providing a magnified view of manual manipulation of an individual to that individual comprising the steps of: (a) viewing the manual manipulation by image transmitting means; (b) generating electrical signals representing an image of said manual manipulations; (c) positioning a first viewing means in optical alignment with said individual; (d) regenerating said image on said first viewing means; (e) selectively magnifying by magnification adjustment means the image regenerated on said first viewing means; and (f) placing said image transmitting means and said first viewing means in a unitary housing adapted to be worn on the head of the individual.
Claim 7
Dependent Claim
33 words
The method as set forth in claim 4 including the step of: (a) positioning said magnification adjustment means within close proximity to the individual enabling said individual to manipulate said magnification adjustment means.
Claim 8
Dependent Claim
31 words
The method as set forth in claim 4 including the step of: (a) placing said image transmitting means and said first viewing means in a line of sight of the individual.
Claim 9
Dependent Claim
64 words
The method as set forth in claim 4 wherein: (a) said image transmitting means comprises two vidicon cameras, and including the steps of: (b) positioning said cameras in said housing such that lines of view of each of the cameras converge defining an angle of convergence; and (c) rotating one of said cameras relative to the other to selectively vary said angle of convergence.
Claim 10
Dependent Claim
89 words
A television microscope apparatus comprising: (a) a television camera; (b) a television screen; (c) a video circuit interconnecting said camera and said screen, receiving a signal representative of an image sensed by said camera, and providing a signal representative of said image to said screen to reproduce said image thereon; and (d) head band means having said camera and said screen positioned thereon for sensing said image and reproducing said image substantially along the optical axis of one of the eyes of a wearer of said head band means.
Claim 11
Dependent Claim
89 words
A television microscope apparatus comprising: (a) a television camera; (b) a television screen; (c) a video circuit interconnecting said camera and said screen, receiving a signal representative of an image sensed by said camera, and providing a signal representative of said image to said screen to reproduce said image thereon; and (d) head band means having said camera and said screen positioned thereon for sensing said image and reproducing said image substantially along the optical axis of one of the eyes of a wearer of said head band means.
Claim 12
Dependent Claim
24 words
An apparatus as set forth in claim 8 including: (a) a magnification control for adjusting the magnification of the image reproduced on said screen.
Claim 13
Dependent Claim
62 words
An apparatus as set forth in claim 8 including: (a) a stereoscopic pair of sets of said camera and said screen positioned on said head band means; and (b) a convergence control for adjusting the angle between the sets of said camera and screen to effect convergence of the axes of said sets at a selected distance in front of said cameras.
Claim 14
Dependent Claim
27 words
An apparatus as set forth in claim 8 including: (a) a remote television monitor connected to said video circuit and positioned remotely from said head band means.
Claim 15
Dependent Claim
34 words
An apparatus as set forth in claim 8 in combination with: (a) a head rest stand for engagement by the head of a wearer of said apparatus to facilitate steady viewing through said apparatus.
