A display apparatus, that includes current driving type luminescent elements, has a driving system that takes the conduction types of TFTs to control the emission of the luminescent elements into consideration. The method, in part, involves an article of manufacture that provides a manifestation, or visually observable indication on an exterior surface, of a relative state of the warm-bodied animal’s body temperature, either being too cold or too hot, as a measure against relative levels of hypothermia or hyperthermia, or poor circulation. The frame allocation controller further determines a frame allocation of the downlink portion and the uplink portion of TDD frames used by the plurality of RF modems to communicate with the first group of wireless access devices. The thumb screw has a head having an under surface and a shank formed on the under surface.
