An electronic device includes a chassis and a bracket. The container has a peripheral wall extending angularly about and longitudinally relative to the axis, and an opening extending longitudinally relative to the axis to provide for movement of material into and out of said space. The method further includes using a lazy Viterbi decoder to decode the convolutional codes. Frequently occurring segments are encoded with unique compression codes, while all other infrequently occurring segments are encoded with a common compression code. Information is generated supporting medical diagnosis based on the automatic analysis.
