Abstract
Abstract A fluid detection system capable of displaying the conditions in the environs of a large number of fluid detection probes and correlating each condition with the particular probe that detected it. There are a plurality of probes, each having a comparator preset with a unique probe identifier, such as a binary number. A counter produces digital signals representative of the binary numbers. The probe comparators are responsive to the numbers outputted by the counter and are connected to the probe power circuitry. When each comparator receives the signal corresponding to its preset number, it triggers its associated probe to produce status signals. A display circuit responds to both the number output by the counter and the probe status signals to simultaneously display the probe number and an indication of probe status.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
182 words
An apparatus for detecting the presence of fluids comprising: a plurality of probes for detecting the fluid state of their environment; means for producing a plurality of digital probe signals, each signal corresponding to a binary number, one number uniquely associated with each of said probes; a plurality of comparator means for comparing said probe signals to a predetermined probe identifier and for producing a status signal indicative of the fluid environment of the probe upon reception of the probe signal corresponding to the identifier, one of said comparator means being associated with each of said probes; and output means responsive to the probe signals and the status signals for producing an indication of the detected fluid state correlated with each of said probes, said means including at least two segmented electronic number displays, at least one of said displays responsive to said probe signal for displaying said numbers corresponding to said probes and another of said displays having at least three horizontal segments and wherein the different probe status conditions are indicated by activating a different one of said horizontal segments.
