Abstract: An example method for residual overcurrent protection includes determining an increment amount for residual overcurrent protection. The method further includes determining a decrement amount for residual overcurrent protection. The method further includes determining a count value based at least in part on the increment amount, the decrement amount, and a previous count value. The method further includes detecting an overcurrent condition based at least in part on the count value and a residual overcurrent limit. The method further includes controlling a generator to correct the overcurrent condition responsive to detecting the overcurrent condition.

Abstract: A control system performs a method of controlling a wing of an airplane. The control system includes an optical fiber, a bending device and a processor. The optical fiber is configured to receive light having an input optical phase. The bending device applies an external force on the optical fiber. The external force causes the light exiting the optical fiber to have an output optical phase. a processor determines a phase shift between the input optical phase and the output optical phase and controls the wing based on the phase shift.
