Abstract: A runway incursion avoidance system includes a plurality of surveillance sub-systems that are configured to detect whether an approach and a surface of an aviation runway is currently occupied or will soon be occupied by an object, such as an aircraft, vehicle, pedestrian, wild animal, or other foreign object. The surveillance sub-systems each broadcast one or more occupancy states of the aviation runway. The runway incursion avoidance system further includes a plurality of runway status light sub-systems that control one or more runway status lights depending on the occupancy states broadcast by the surveillance sub-systems. The runway status lights may include Departure and Approach Warning Lights (DALs) to indicate runway status to aircraft taking off from the runway and landing on the runway, or Runway Entrance Lights (RELs) to indicate runway status to aircraft, vehicles, and pedestrians preparing to cross a runway.

Abstract: According to one aspect, the present invention provides an apparatus for accumulating products, (1) such as a refrigeration apparatus, comprising: at least one station (2) where products are to be accumulated; the station having an entry (9) for products (10) at one end and an exit (11) for products (10) at an opposite end; infeed means (3, 4), for conveying the products to the station entry; outfeed means (5, 6) for conveying products away from the station entry; and moving means (7) for moving products from the station entry into the station and for moving products out of the station at the exit to the outfeed means.

Abstract: The present invention provides methods of identifying agents that bind polypeptides critical for the survival of Haemophilus spp., preferably H. influenzae. The present invention also provides critical polypeptides and the polynucleotides encoding the critical polypeptides.
