A device used to cover the breaks or holes in exterior vinyl or other type of siding on the exterior corners of buildings. The method includes generating a sequence of symbols, the sequence of symbols including preamble symbols and a data symbol. The chip is partially embedded in the depression to dispose on the substrate. The plate may be bolted or screwed to the back of the guitar via the screw holes and tremolo claw holes. Subsequently, the system can estimate an angle-of-arrival direction for a signal-of-interest and at least one signal-not-of-interest. A suitable distillation system is also disclosed.
