Abstract: The aircraft control systems and methods disclosed herein are configured to detect a residual error associated with a flight control computer of an aircraft and mitigate the effect(s) of such residual error in order to maintain safe operation of the aircraft. In some embodiments, the systems and methods are configured to detect an out-of-flight-envelope situation of the aircraft and determine whether or not the flight control computer is attempting to recover the aircraft from the out-of-flight-envelope situation. If the flight control computer is perceived as attempting to recover the aircraft from the out-of-flight-envelope situation, the flight control computer is permitted to continue controlling the aircraft. Otherwise, the excursion outside of the normal flight envelope is perceives as potentially having been caused by a residual error and the flight control computer is prevented from continuing to control the aircraft.

A liquid tank is supported by the frame and is configured to hold liquid to increase the effective mass of the shooting rest to reduce recoil felt by a shooter when the firearm is fired.

Abstract: Rotary position sensors are provided. In one example implementation, a rotary position sensor can include a first member and a second member, one of the first and second members having a transmit aerial and a receive aerial and the other of the first and second members having an intermediate coupling element.

The intermediate coupling element comprises a conductive material arranged in a pattern. The pattern of the intermediate coupling element and the layout of the first and second set of current loops are mutually arranged such that any electromotive force induced in the first set of current loops by a background magnetic field is substantially balanced by an electromotive force induced in the second set of current loops by the background magnetic field.
