A snake tool adaptor capable of coupling commercially available heavy duty drain cleaning cables and attachments normally associated with heavy electric drain cleaners with a portable rotary driving tool such as a hand-held drill. The multi-layer top electrode includes at least a top metal layer and a bottom metal layer. If the amount of data received exceeds the predefined threshold, then the network interface device is caused to be awake during a subsequent time slot. The instructions of interaction are arranged to define how the transfer of generated information is to be performed. A bill of materials is automatically checked for faults and generated for the design system and provided to the design engineer.
