Patent ID: 7050887

Claim:
A Wireless Sensor and Control Transmitter Subsystem for a hydraulic system controlled by an existing controller unit, consisting: a master module unit having electronic circuitry that interfaces with an existing hydraulic system controller and also communicates wirelessly with one or more field module unit(s), said field module unit further having electronic circuitry that communicates with one or more field electromechanical control devices or sensors, wherein the circuitry of said master module unit is capable of generating digital command signals, wirelessly transmitting said digital signals to said field module unit, said field module unit circuitry is capable of regenerating said digital command signals received from said master module unit to recreate said controller command signal and of transmitting said recreated signal to the field electromechanical control devices or sensors, and the circuitry of said field module unit is capable of converting signals from said electromechanical control devices or sensors into digital signals and wirelessly transmitting said digital signals to said master module unit, and further said master module unit circuitry is capable of converting the digital signals received from said field module unit to reproduce the electromechanical control devices or sensors signals and transmit them to the controller in their originally received form or format.
