Abstract: An arrangement for supplying heated air to a wing anti-icing system on an aircraft propelled by a jet engine includes, but is not limited to, an ejector that is configured for coupling to a wing anti-icing system. The ejector is further configured to receive a first flow of air, to entrain a second flow of air with the first flow of air, the second flow of air having a lower temperature than the first flow of air, to mix the first flow of air with the second flow of air to form a combined flow having a temperature and a volume suitable for use by the wing anti-icing system, and to exhaust the combined flow into the wing anti-icing system.

Abstract: An enhanced vision system is provided for an aircraft performing a landing maneuver. Accordingly to non-limiting embodiments, a processor onboard the aircraft receives data from sensors or systems onboard the aircraft and determines a position of the aircraft relative to a runway using the data. Responsive to this determination, the processor adjusts the gain of a first vision system and a second vision system. Images from the first vision system and the second vision system are merged and displayed to the pilot until the completion of the landing maneuver.

Abstract: A frequency selective surface includes resonators (104) which are spherically shaped and have an arrangement which defines a periodic array (103) of rows (112) and columns (114). The periodic array extends in at least two orthogonal directions. A registration structure (602) is provided and arranged so that it at least partially maintains a position of each of the resonators in a predetermined spatial relationship with respect to adjacent ones of the plurality of resonators to define the array. Each of the resonators is formed of a conductive material and is electrically insulated from adjacent ones of the resonators forming the array by an insulator material.

Abstract: A rear view projection apparatus for viewing from a rear screen side the images projected onto the screen front side. This apparatus comprises a projector, a screen made of a transparent plastic material, a base having a recess for the screen, a projector support cantilevered from the base, and a retractable screen support having an extender scissors unit for raising the screen for use or for lowering the screen into the recess for storage.
