Abstract

In, for example, a thread surveillance and monitoring system, signal transducers are coupled in series, and also in parallel, and each is provided with first circuitry which is operative, in response to the occurrence of a signal from the transducer, to generate a control signal which is fed to the immediately subsequent signal transducer in the series coupling, this transducer having, like the remainder, second circuitry for generating, in response to the control signal, a deviation in the transducer signal, and a further control signal which is fed to the immediately subsequent signal transducer in the series coupling, whereby there occurs, on the signal line providing the parallel connection, a transducer signal having a deviation for each one of the signal transducers between the transducer generating the transducer signal and one end of the signal line. These deviations are counted at a central location, to identify the activated transducer. <IMAGE>
