A suspension assembly comprises four springs spaced at four distinct locations. In one embodiment, the optical fiber array includes at least two subunits, each of the subunits having a respective subunit matrix, and the optical fiber array also includes a common matrix having a plurality of intermittent weakened portions. The input and output ends may be opposite ends of unitary elements andor may be remote from one another and connected by wire or wirelessly. In one embodiment, the invention provides a video production system having a processing unit in communication with one or more of the video production devices. The sending side terminal device encodes and transmits the video data. Similarly, the ball pads on the bottommost wiring layer are organized into ball pad rings.
