Abstract
Abstract A combination of large scale integrated digital circuits for providing universally selectable decoding, encoding and over-interrogation control functions in a radar transponder. The circuits are implemented in semiconductor chip and hybrid circuit form and selection of desired functions may be accomplished by external switches, by jumper wiring or by custom designed printed circuit boards. The use of large scale integrated circuit techniques allows facilitation of multiple control functions without necessity of bulky assemblies or high power consumption.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
131 words
A universal pulse assembly apparatus for a transponder the transponder having a receiver and a transmitter, the apparatus in combination comprising: means for decoding a coded video pulse signal from the receiver, said decoding means having first selecting means for determining one of a plurality of predetermined video pulse codes; means for encoding a modulating pulse signal for the transmitter, said encoding means having second selecting means for determining one of a plurality of predetermined transmitter pulse codes; and means for controlling the pulse response rate of the transponder; said controlling means having third selecting means for determining one of a plurality of maximum allowable transponder response rates, said controlling means operable to limit modulation of the transponder when said response rate of the transponder exceeds said selectable maximum response rate.
Claim 2
Dependent Claim
131 words
A universal pulse assembly apparatus for a transponder the transponder having a receiver and a transmitter, the apparatus in combination comprising: means for decoding a coded video pulse signal from the receiver, said decoding means having first selecting means for determining one of a plurality of predetermined video pulse codes; means for encoding a modulating pulse signal for the transmitter, said encoding means having second selecting means for determining one of a plurality of predetermined transmitter pulse codes; and means for controlling the pulse response rate of the transponder; said controlling means having third selecting means for determining one of a plurality of maximum allowable transponder response rates, said controlling means operable to limit modulation of the transponder when said response rate of the transponder exceeds said selectable maximum response rate.
Claim 3
Dependent Claim
136 words
A universal digital pulse assembly apparatus for a transponder the transponder having receiver and a transmitter, the apparatus in combination comprising: means for digitally decoding a coded video pulse signal from the receiver, said digital decoding means having first selecting means for determining one of a plurality of predetermined video pulse codes; means for digitally encoding a modulating pulse signal for the transmitter, said digital encoding means having second selecting means for determining one of a plurality of predetermined transmitter pulse codes; and means for digitally controlling the pulse response rate of the transponder; said controlling means having third selecting means for determining one of a plurality of maximum allowable transponder response rates, said controlling means operable to limit modulation of the transponder when said response rate of the transponder exceeds said selectable maximum response rate.
Claim 4
Dependent Claim
136 words
A universal digital pulse assembly apparatus for a transponder the transponder having receiver and a transmitter, the apparatus in combination comprising: means for digitally decoding a coded video pulse signal from the receiver, said digital decoding means having first selecting means for determining one of a plurality of predetermined video pulse codes; means for digitally encoding a modulating pulse signal for the transmitter, said digital encoding means having second selecting means for determining one of a plurality of predetermined transmitter pulse codes; and means for digitally controlling the pulse response rate of the transponder; said controlling means having third selecting means for determining one of a plurality of maximum allowable transponder response rates, said controlling means operable to limit modulation of the transponder when said response rate of the transponder exceeds said selectable maximum response rate.
