Title: CHARACTERIZATION OF SINGLE OR MULTIPLE DEVICES IN A SYSTEM
Abstract: [0001]    A system for a gas turbine engine includes an electrical interface device (90), a sensing / control / identification device (68A, 68B, 68C), and a remote processing unit (66). The electrical interface device (90) has electrical interface device data. The electrical interface device (90) is operatively connected to a sub-system component (70) that is provided with a shielding (84). The sensing / control / identification device (68A, 68B, 68C) is disposed within the sub-system component (70) and is attached to the electrical interface device (90). The remote processing unit (66) is in electromagnetic communication with the sensing / control / identification device (68A, 68B, 68C).
