Abstract: A trailer force measurement system includes a tow hitch, a hitch mount connected to the tow hitch and a spring bar connected to the hitch mount. The trailer force measurement system also includes a trailer having a frame, where the spring bar is connected to the trailer frame via a bracket. A hitch coupler is then connected to the trailer frame and configured to releasably couple the trailer frame to the hitch mount. A force measurement device is then disposed on the bracket and configured to measure force exerted on the bracket by the spring bar.

Abstract: A method for use in the synthesis of graphene is described that comprises the steps of annealing a substrate in a hydrogen gas atmosphere, subsequently undertaking a deposition and nucleation step in which a relatively thick carbon layer is deposited onto the substrate and subsequently thinned to form small graphene islands or nuclei, undertaking a graphene growth step in which the graphene islands or nuclei expand and coalesce, and subsequently allowing the substrate to cool. A sensor 10 incorporating the graphene sheet is also described.
