A memory card includes a non-volatile memory, a memory controller for controlling the operation of the memory card. The integrated circuit includes a spur controlled clock that operates the clock frequency, and a DC-DC converter circuitry that includes a first power switch, and a second power switch. The transducer at least partially comprises silver. In use, the lattice work side of the device preferably does not contact the cargo, but provides a foundation for attaching a plurality of anchor points located within the perimeter of the mesh tarp portion. The first plastic casing, for example, may be made of a thermoset plastic material and the second plastic casing may be made of a thermoplastic material.
