Abstract: A flight control system commands drag devices such as flight spoilers according to pilot or autopilot longitudinal command. Furthermore, the flight control system monitors a set of flight parameters to determine whether the aircraft is operating inside the permitted safe envelope, hence, incorporating envelope automatic exceeding disengagement. This invention allows the aircraft to descend in a steeper glide path than the 3° used in the normal approach, while keeping speeds unchanged.

Abstract: The present invention provides for cutting operations using linear thermite charges; the charges cut one dimensional or two dimensional geometric shapes; the invention is useful for structure entry or demolition.

Abstract: A method and apparatus that allows a ring to be inserted into the primary devices lens element or adapter without changing the offset (i.e., the distance between the camera and the lens along the optical path). This can be at the ocular or recording end of lenses. The ring can be hand turned and gently tightened with a key similar to a spanner wrench. The ring will maintain it's place and location when the amount of pressure applied to the accessory is less then that applied to the ring. When the insertion ring is in place, the screw mount diameter of the primary device is smaller without adding additional unnecessary offset when mounting the accessory. The present application covers the usage, design and manufacture of insertion rings, insertion ring keys and any modifications to the primary device.
