Scene classification by an artificial neural network.

The present invention relates to a device for use on airplanes to permit visual identification and location by pilots of other aircraft in the vicinity so as to avoid mid-air collision. The device refracts and reflects light so as to make the plane visually observable by pilots, any other aircraft in the area. The device is formed as a tape and attached to various parts of an aircraft. Refracting elements redirect light towards reflecting elements for intensifying and directing it therefrom, creating a readily recognizable shimmering image.
