Via layout with via groups placed in an interlocked arrangement for suppressing the crack propagation along the domain boundary between the via groups. The configuration array generates locationprotocol signals that each direct one of the plurality of drivers on the bus to employ location-based bus termination or protocol-based bus termination. An image data system is disposed below the prism structure. Movement of the handle assembly stores energy within the biasing means so that the biasing means exerts a corresponding force on the foot.
