A flat panel display and backlight module thereof. The nanowires and nanoribbons are characterized by a periodic longitudinal modulation, which may be a compositional modulation or a strain-induced modulation. The redundancy of such coded signals as generated using the principles herein is in the range of approximately 7%, and hard decision decoding may be performed on such coded signals generated herein. The pad member is repositionable between two opposing sides each having a wear surface that contacts the floor. Therefore, it is possible to provide the normative action candidates considering the risk of contact between the host vehicle 400-and the obstacles around the host vehicle. The systems and methods can make use of a special guide wire assembly that includes a guide wire having an enlarged component or tip element on its distal end that can be used to engage the distal end of a bone treatment tool in response to a pulling motion on the guide wire.
