Abstract: The present invention relates to a lock button assembly for installation on a threaded actuating member operatively connected to a vehicle door locking mechanism. The assembly has a manually engageable lock button having a longitudinally extending bore. The bore is configured to receive a threaded end portion of the actuating member. The lock button has an opening on one side thereof providing access to the bore. A clip member is mounted exteriorly to the lock button. The clip member has a resilient projection extending inwardly through the opening and into the bore for frictional engagement with the threaded portion. The projection is biased to permit ingress of the actuating member into the bore and to prevent egress of the actuating member from the bore. The present invention also relates to a method for installing a lock button assembly on a threaded actuating member operatively connected to a vehicle door locking mechanism.

Abstract: A vehicle guidance system wherein a vehicle is guided in either a command guidance mode or a homing guidance mode. In the command guidance mode, the target tracking element, used during the homing guidance mode serves as an inertial reference element. Such element is attitude stabilized in pitch and yaw by mechanically driven means used in both modes, such means driving the reference element with respect to the vehicle's body and, in roll, by the vehicle's roll autopilot to aerodynamically control the vehicle's attitude in roll.
