A modular magazine assembly in a fastener-driving tool having a nosepiece includes a first magazine housing portion secured to the tool and at least partially defining a chamber for fasteners. The device includes a structured film comprised of at least one of a ferromagnetic and ferrimagnetic material. Prior to performing an electronic shutter operation, a determination is made as to whether or not a current level in the electronic shutter layer substantially equals or exceeds a threshold current level. A content server is coupled to the IVR unit for transferring the digital multimedia content to the premise appliance. In a multiple lane parallel optic embodiment, and by signaling a loss of a signal on a per lane basis, a break or fault in a sub-set of fibers of a parallel optical link will not result in the entire parallel optic link being lost. Such composites may be used in structural and non-structural applications and exhibit improved mechanical properties, thermal properties andor resistance to biological degradation.
