Drill bit reinforcing members or blanks of this invention are formed from high-strength steels having a carbon content less than about 0. The structure and method allows for the effective inductive testing of magnetic write heads at wafer level even if the write heads have an inductance that is too low to be effectively measured directly. The outer dimensions of the frame are less than the inner dimensions of a network connection box in which it is to be mounted, and the back plate is spaced from a rear wall of the box when installed to define a concealed cable management area behind the frame. The rearward face of the overhead sign structure on an opposing side from the forward face has a secondary orientation with respect to other traffic flow different from the oncoming vehicle traffic. After the subregion is discontinued, clear commands may once again be handled according to the conventional technique. In one embodiment, the deflectors’ support members pivot about their inner ends in the mode of a rotary kite that may economically project a resilient structure over a very large area.
