Homeland Intelligence Systems Technology \u201cH-LIST\u201d comprises nano-sensors embedded in a silicon substrate and etchedfused in a micro-fibered material. On the basis of the information items, the microprocessor calculates the weight values of a transmitting section and a receiving section for every terminal station and every hopping frequency, and stores them in a weight value table. A bit case containing a roller bit is moved so as to protrude from an attachmentdetachment path formed in a rotary valve into the bit containing portion, and is fixed by a cotter to support an excavating reactive force.
