Abstract

A system for a gas turbine engine includes an electrical interface device, a sensing/control/identification device, and a remote processing unit. The electrical interface device has electrical interface device data. The electrical interface device is operatively connected to a sub-system component that is provided with a shielding. The sensing/control/identification device is disposed within the sub-system component and is attached to the electrical interface device. The remote processing unit is in electromagnetic communication with the sensing/control/identification device.
