Abstract
Abstract A video system is disclosed having a weapon-mounted video camera (12) transmitting video signals to a remotely located video display (14). The video display is mounted to the helmet (40) of a soldier (36), and includes a sight reticle (50) superimposed on the image of the target (46) so that the soldier (36) can aim the weapon (38) by moving it until the target object (46) as displayed by the video display (14) is aligned with the sight reticle (50). A low probability of transmission interception of the video signals is accomplished by using a nonvisible light carrier wavelength in free space, which wavelength is characterized by a high degree of absorption due to atmospheric water vapor.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
132 words
A video system, comprising: an imaging system for generating video signals representative of an object; a video receiver and display remotely located from said imaging system; an optical link operating between a short UV and a far IR wavelength for transmitting said video signals between said imaging system and said video receiver; means for presenting to the person different images superimposed one on another so that plural images can be viewed simultaneously, said presenting means comprising a partially reflecting mirror disposed in the paths of two images; and means removably attachable to a person's head, including means for mounting thereto said video display in a position such that the person can view the display without the use of the person's hands and wherein the person can move about in an unimpeded manner.
Claim 2
Dependent Claim
132 words
A video system, comprising: an imaging system for generating video signals representative of an object; a video receiver and display remotely located from said imaging system; an optical link operating between a short UV and a far IR wavelength for transmitting said video signals between said imaging system and said video receiver; means for presenting to the person different images superimposed one on another so that plural images can be viewed simultaneously, said presenting means comprising a partially reflecting mirror disposed in the paths of two images; and means removably attachable to a person's head, including means for mounting thereto said video display in a position such that the person can view the display without the use of the person's hands and wherein the person can move about in an unimpeded manner.
Claim 3
Dependent Claim
54 words
The video system of claim 1 further including means for movably mounting said display to said attachable head means so that said display can be moved out of the line of sight vision of the person; and means for pivotally mounting said receiver to said attachable head means and being integral with said display.
Claim 4
Dependent Claim
38 words
The video system of claim 1 further including a night vision goggle attachable to said attachable head means so that an object can be viewed simultaneously by the use of said video display and said night vision goggle.
Claim 5
Dependent Claim
54 words
The video system of claim 1 further including in said video camera, means for transmitting said video signals to said video display through a free space transmission medium with a wavelength of greater than approximately 150 nanometers; and means for transmitting video signals from said imaging system to said display through a physical medium.
Claim 6
Dependent Claim
16 words
The video system of claim 1 wherein said video display comprises a vacuum fluorescent video display.
Claim 7
Dependent Claim
35 words
A video system of claim 1 further including in said transmission system means for transmitting the video signals with a carrier wavelength having a high degree of atmospheric absorption according to a desired atmospheric parameter.
Claim 8
Dependent Claim
37 words
The video system of claim 1 further including a plurality of remotely located video displays, each said display including means for receiving the video signals and displaying the object toward which said video imaging system is directed.
Claim 9
Dependent Claim
21 words
The video system of claim 1 further including a plurality of video transmission systems, each transmitting at a different carrier frequency.
Claim 10
Dependent Claim
64 words
The video system of claim 1 further including illumination means for transmitting nonvisible light in a travel path of the person, and said imaging system includes means for receiving the nonvisible light reflected from objects in the travel path, and means for transmitting video signals representative of the objects in the travel path, whereby said video display displays the travel path to the person.
