A system and method for evaluating performance of a microphone for long-distance speech recognition, which enables a robot to receive and respond to voices. The heat conduction support body has a first face and a second face opposite to the first face. The electrical energy generator may be associated with a carried item, such as a backpack. The unification mounting positions the output of the first device module in card handoff alignment with the input of the second device module. The adapters have a roll bearing surface, a projection surface with a first end and a second end such that the first end is coterminous and substantially perpendicular to the roll bearing surface at each point along an interface formed therebetween, and an actuating surface angularly coterminous with the second end of the projection surface. The first and second substrates are thus bonded together and accurately aligned.
