Encoding data in a pattern of symbols on a surface. Elements of such distribution systems and requirements of relevant standard, are stored in a computer’s memory. The extension has a first end inserted in the assembly and a second end having at least one bonding pad thereon. Extending inwardly towards the center of the allocation slot is a resilient arm having a button at the end thereof. Therefore, the number of overhead processors required for multi-byte data transmission is reduced, potentially reducing the number of required overhead processors in digital communications to 1. Various combinations of several processing techniques are employed including spectral estimation processing such as discrete Fourier transform processing, circular convolution, signal scalingnormalization, and complex autocorrelation.
