The invention provides a new collagen based technology. These modules are coupled together by a bus in a plurality of nodes and provide for the dynamic message routing on a topic between publishing nodes and subscribing nodes. The movable body has magnet retaining portions having a substantially triangular shape and placed between adjacent inner yokes and between adjacent outer yokes.
