Abstract: There is provided a composite structure, comprising a protective structure comprising a plurality of ballistic layers arranged as a stack; and an ancillary structure adjacent to the protective structure adapted to at least partly absorb a force acting on the protective structure. The ancillary structure comprises at least one first layer comprising an aerogel arranged to at least partly absorb a force acting on the protective structure. A part of each ballistic layer is moveable relative to at least one adjacent ballistic layer and wherein a part of each ballistic layer is connected to at least one adjacent ballistic layer so as to restrict relative movement of a part of each of the adjacent ballistic layers.

Abstract: A test apparatus for testing a video processing apparatus comprises means for receiving from the video processing apparatus a video output representative of a test sequence, the test sequence comprising a plurality of frames, each frame comprising an image of a respective different one of a plurality of frame identifiers; means for obtaining a sequence of sets of frame data from the video output, each set of frame data representative of a frame; and means for processing each set of frame data to determine the frame identifier for that frame.

Abstract: A portable test apparatus for testing a commodity, the commodity comprising a cable modem, router and/or set top box, wherein the commodity is configured for connection to a cable network, the portable test apparatus comprises a cable modem termination system (CMTS), and an attenuator, wherein the CMTS is configured to provide a signal to the commodity under test over a connecting cable, and the attenuator is configured to attenuate the signal level from the CMTS such that when the commodity receives the signal from the CMTS over the connecting cable, at least one characteristic of the signal received over the connecting cable simulates at least one operating signal characteristic of the cable network for connection to which the commodity is configured.
