An apparatus and corresponding method for enabling the use of a plurality of control heads for operating a transceiver designed to operate with a single control head via a data bus. Link means are arranged between the belt assembly and the pair of straps, together forming a dorsal holder element arranged to enable the belt assembly to be slidably mounted relative to the dorsal plane. Moreover, a drill bit assembly is formed to be actually driven by a pneumatic source towards the secured bomb to push it against the fingered aperture to secure it firmly in place and to drill a hole therein while injecting fluid through a telescoping sleeve. The combustion chamber provides means to induce pyrolysis, tar cracking, and char gasification of the raw biomass materials to produce gases and ash.
