Abstract
Abstract Apparatus for superimposing numerical information on the field of view of binoculars. The invention has application in the flying of radio-controlled model airplanes. Information such as, for example, airspeed and angle of attack are sensed on a model airplane and transmitted back to earth where this information is changed into numerical form. Optical means are attached to the binoculars, that a pilot is using to track the model airplane, for displaying the numerical information in the field of view of the binoculars. The optical means includes means for focusing the numerical information at infinity whereby the user of the binoculars can see both the field of view and the numerical information without refocusing his eyes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
85 words
Apparatus for displaying, in the field of view of binoculars, numerical information about an object being viewed by the binoculars comprising: binoculars, including an objective lens and two barrels; means for sensing information about said object; transmitter means for transmitting said information; receiver means for receiving said transmitted information; means for transforming said received information into numerical form and displaying it on an incandescent readout; and optical means attached to said binoculars for superimposing said incandescent readout onto the field of view of said binoculars.
Claim 2
Dependent Claim
85 words
Apparatus for displaying, in the field of view of binoculars, numerical information about an object being viewed by the binoculars comprising: binoculars, including an objective lens and two barrels; means for sensing information about said object; transmitter means for transmitting said information; receiver means for receiving said transmitted information; means for transforming said received information into numerical form and displaying it on an incandescent readout; and optical means attached to said binoculars for superimposing said incandescent readout onto the field of view of said binoculars.
Claim 3
Dependent Claim
40 words
Apparatus according to claim 1 wherein said optical means includes means for focusing said incandescent readout at infinity whereby the user of said binoculars does not have to refocus his eyes to see both the object and the incandescent readout.
Claim 4
Dependent Claim
19 words
Apparatus according to claim 2 wherein said means for focusing said incandescent readout at infinity is a collimating lens.
Claim 5
Dependent Claim
30 words
Apparatus according to claim 1 wherein said optical means includes a beam splitter that reflects the incandescent readout and transmits the light from the field of view of the binoculars.
Claim 6
Dependent Claim
68 words
Apparatus according to claim 1 wherein said optical means includes: a collimating lens; means for directing an image of said incandescent readout into said collimating lens; and means mounted in front of one barrel of said binoculars for transmitting light from the field of view of said binoculars and for reflecting the image of said incandescent readout from said collimating lens onto the objective lens of said binoculars.
Claim 7
Dependent Claim
24 words
Apparatus according to claim 5 wherein said means for directing an image of said incandescent readout into said collimating lens includes a negative lens.
Claim 8
Dependent Claim
23 words
Apparatus according to claim 6 wherein said means for directing an image of said incandescent readout into said collimating lens includes mirror means.
