Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
229 words
A sensor system responsive to a fire or explosion comprising: a) a first control signal means, responsive to a first radiant energy detector, for generating a first control signal when the first detector detects electromagnetic energy within a first spectral band having an amplitude greater than a first predetermined level; b) a second control signal means, responsive to a second radiant energy detector, for generating a second control signal when the second detector detects electromagnetic energy within a second spectral band having an amplitude greater than a second predetermined level; c) a third control signal means, responsive to the first and second radiant energy detectors, for generating a third control signal whenever the ratio of the energy detected by the first detector to the amplitude of the energy detected by the second detector exceeds a third predetermined level; d) a fourth control signal means, responsive to the third control signal, for: (i) generating a fourth control signal whenever the third control signal is not generated, and (ii) not generating the fourth control signal whenever the third control signal is generated and for an additional predetermined amount of time after the third control signal is no longer generated; and e) output gate means, responsive to the first, second, and fourth control signals, for generating an output signal only when the first, second, and fourth control signals are all simultaneously generated.
Claim 2
Dependent Claim
229 words
A sensor system responsive to a fire or explosion comprising: a) a first control signal means, responsive to a first radiant energy detector, for generating a first control signal when the first detector detects electromagnetic energy within a first spectral band having an amplitude greater than a first predetermined level; b) a second control signal means, responsive to a second radiant energy detector, for generating a second control signal when the second detector detects electromagnetic energy within a second spectral band having an amplitude greater than a second predetermined level; c) a third control signal means, responsive to the first and second radiant energy detectors, for generating a third control signal whenever the ratio of the energy detected by the first detector to the amplitude of the energy detected by the second detector exceeds a third predetermined level; d) a fourth control signal means, responsive to the third control signal, for: (i) generating a fourth control signal whenever the third control signal is not generated, and (ii) not generating the fourth control signal whenever the third control signal is generated and for an additional predetermined amount of time after the third control signal is no longer generated; and e) output gate means, responsive to the first, second, and fourth control signals, for generating an output signal only when the first, second, and fourth control signals are all simultaneously generated.
Claim 3
Dependent Claim
34 words
