Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
124 words
Apparatus for processing an original pulsed carrier wave comprising: means having plural port means for converting said original pulsed carrier wave to first and second carrier waves appearing at respective first and second of said plural port means, said first and second carrier waves having quadrature phase relation one with respect to the other, and first and second signal processing means respectively coupled to said first and second port means for receiving said respective first and second carrier waves, said signal processing means each comprising in series connected relation; first switching means adapted to be conducting only for the duration of said original pulsed carrier wave signal, and shift register means adapted to accept signals for storage conducted thereinto by said first switching means.
Claim 2
Dependent Claim
124 words
Apparatus for processing an original pulsed carrier wave comprising: means having plural port means for converting said original pulsed carrier wave to first and second carrier waves appearing at respective first and second of said plural port means, said first and second carrier waves having quadrature phase relation one with respect to the other, and first and second signal processing means respectively coupled to said first and second port means for receiving said respective first and second carrier waves, said signal processing means each comprising in series connected relation; first switching means adapted to be conducting only for the duration of said original pulsed carrier wave signal, and shift register means adapted to accept signals for storage conducted thereinto by said first switching means.
Claim 3
Dependent Claim
17 words
Apparatus as described in claim 1 wherein said means for converting comprises hybrid network energy propagation means.
Claim 4
Dependent Claim
48 words
Apparatus as described in claim 2 comprising: first and second balanced mixer means each having first and second port means, said first and second port means of said hybrid network means being respectively connected in energy exchanging relation with said first port means of said balanced mixer means.
Claim 5
Dependent Claim
30 words
Apparatus as described in claim 3 comprising: local oscillator means, said local oscillator means being connected in energy exchanging relation with said second port means of said balanced mixer means.
Claim 6
Dependent Claim
43 words
Apparatus as described in claim 1 comprising: means for detecting the envelope of said original pulsed carrier wave, and means coupled to said detecting means for controlling the conductivity of said first switching means in said respective first and second signal processing means.
Claim 7
Dependent Claim
28 words
Apparatus as described in claim 5 comprising clock means for supplying synchronizing clock signals to said shift register means in said respective first and second signal processing means.
Claim 8
Dependent Claim
25 words
Apparatus as described in claim 6 comprising switching means connected in series relation with saiD clock means for controlling the supply of said clock signals.
Claim 9
Dependent Claim
29 words
Apparatus as described in claim 7 comprising means coupled to said detecting means for controlling the conductivity of said switching means connected in series relation with said clock means.
Claim 10
Dependent Claim
54 words
Apparatus as described in claim 1 comprising: second switching means in said first and second signal processing means providing, when conducting, a feed back path across said shift register means for the purpose of recirculating signals stored in said shift register means, and first command signal means for causing said switching means to conduct.
Claim 11
Dependent Claim
69 words
Apparatus as described in claim 1 comprising: third switching means in said first and second signal processing means, providing, when conducting, respective direct connection between said shift register means and said respective first and second port means of said converter means, and second command signal means for causing said third switching means to conduct for the purpose of permitting said converter means to reconstitute said original pulsed carrier wave.
Claim 12
Dependent Claim
28 words
Apparatus as described in claim 9 comprising means for causing said shift register means to shift stored signals when said second switching means is in the conductive state.
Claim 13
Dependent Claim
28 words
Apparatus as described in claim 10 comprising means for causing said shift register means to shift stored signals when said third switching means is in the conductive state.
