Abstract
A system may comprise at least one signal input circuit configured to receive target input signals from at least one sensor device; at least one signal processing unit. Each of the at least one signal processing unit may include at least one signal output circuit configured to output signals to a first electronic connection; and at least one signal extraction circuit configured to obtain a reverse control signal from the first electronic connection; and at least one signal superimposing circuit configured to generate superimposed reverse control signals by superimposing the first reverse control signal with other electronic signals, and output the superimposed reverse control signal to the signal input circuit.
