ABSTRACT:
A plurality of electrically conductive wires is connected between two terminals and cross over each other at crossover points. Wire segments connect adjacent crossover points. All such adjacent connected crossover points have different potentials when a voltage is connected between the terminals. This forms a screen which protects an engine from damage caused by foreign objects carried into the engine intake. When a power source is connected to the terminals, the screen is heated to prevent the accretion of ice.
