Abstract
Abstract A waveguide loop having a circumference approximately an integer multiple of a wavelength at the signal-operating frequency and a directional coupler spaced-apart from the waveguide loop are utilized to effectuate power coupling without significant signal loss between a transmitter and a receiver in relative motion with respect to each other.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
121 words
Apparatus for transmitting a signal within a rotating body comprising: means for transmitting a signal of a predetermined frequency; means for receiving the signal transmitted by said transmitting means, said transmitting means and said receiving means moving relative with respect to each other; a waveguide loop having a circumference approximately an integer multiple of the wavelength of the signal; first coupling means spaced apart from said waveguide loop coupling the signal from said transmitting means to said waveguide loop causing a wave to circulate around said waveguide loop; second coupling means spaced-apart from said waveguide loop and coupling the signal from said waveguide loop to said receiving means; wherein one of said first and second coupling means is a directional coupler.
Claim 2
Dependent Claim
121 words
Apparatus for transmitting a signal within a rotating body comprising: means for transmitting a signal of a predetermined frequency; means for receiving the signal transmitted by said transmitting means, said transmitting means and said receiving means moving relative with respect to each other; a waveguide loop having a circumference approximately an integer multiple of the wavelength of the signal; first coupling means spaced apart from said waveguide loop coupling the signal from said transmitting means to said waveguide loop causing a wave to circulate around said waveguide loop; second coupling means spaced-apart from said waveguide loop and coupling the signal from said waveguide loop to said receiving means; wherein one of said first and second coupling means is a directional coupler.
Claim 3
Dependent Claim
52 words
Apparatus of claim 1 in which said transmitting means and said first coupling means are secured to a high-speed rotating body, said first coupling means moving in a circle having a circumference approximately the same as said waveguide loop, and said second coupling means is stationary with respect to said receiving means.
Claim 4
Dependent Claim
18 words
The apparatus of claim 1 in which both of said first and second coupling means are directional couplers.
Claim 5
Dependent Claim
15 words
Apparatus of claim 1 in which said waveguide loop further comprises a helical line waveguide.
Claim 6
Dependent Claim
18 words
Apparatus of claim 1 in which said circular waveguide is stationary with respect to said second coupling means.
Claim 7
Dependent Claim
18 words
Apparatus of claim 1 in which said circular waveguide is stationary with respect to said first coupling means.
Claim 8
Dependent Claim
23 words
Apparatus of claim 1 in which said first coupling means is a loop coupler and said second coupling means is a directional coupler.
Claim 9
Dependent Claim
50 words
Apparatus of claim 1 including a power transmitter coupled to said waveguide loop, a power receiver mounted on the rotating body and coupled to said waveguide loop, said power receiver receiving a signal from said power transmitter and in response thereto supplying power to energize and operate said transmitting means.
