A rollable structure for suspending a heavy radiation protective garment so as to allow easy movement in a clinical environment subject to exposure to x-radiation. A cobalt silicide layer is formed on an impurity junction region exposed through a contact hole. According to the invention the transmitted bits of the modulated symbols are reordered over the retransmissions in accordance with the selected redundancy version. The NFC tag in this system not only provides status signal but also provides network configure data that eliminates the need to make standalone device configurable for network connectability. The autolab component finds an available client computer, and the client machine is assigned the test packet. Also provided are methods for assembling and using components of the animal containment systems.
