摘要： A wheelchair with a footrest that tucks as a power base on which the wheelchair seat is mounted rotates about an axis parallel to a surface. The rotation of the power base raises the height of the seat above the surface. The footrest, which is coupled to the support, tucks towards the power base and still avoids obstacles on the surface. The footrest tuck improves the maneuverability of the wheelchair by reducing the radius about which the footrest swings as the wheelchair turns.

摘要： An improved aircraft lens attachment system including a plurality of keyways in the lens, which intersect the edge of the lens and a resilient gasket with a plurality of keys located to correspond with the keyways of the lens, each keyway having an aperture passing through it. The improved lens attachment system eliminates the area of the lens, which is susceptible to fatigue cracking. It also provides a more flexible and efficient way to attach a lens to an aircraft.
