A semiconductor device having minute gate electrodes is fabricated with precision. Aspects of the method may comprise amplifying an input signal. The assembly of lenses includes at least a plano-concave lens with its flat surface facing forward away from the camera and a plano-convex lens with its flat surface facing the camera. The method involves transitioning the aerial vehicle from the hover-flight orientation to a forward-flight orientation, such that the aerial vehicle moves from the tether sphere. The linking bracket is configured to at least partially absorb a substantially lateral impact force and, via the inclined surface, to provide a moment of force that at least partially counteracts an opposing moment of force provided by the frame pillar due to the impact force.
