A preferred embodiment of a hand-held radio frequency identification reader includes a first casing suitable for being grasped by a user, a second casing, and a transceiver housed within one of the first and second casings. The valve is movable vertically under water pressure between an upper position wherein water flows through the cap portion side orifice, the bore and through the body vertical pipe, and a lower position where water flows around the cap portion through the internal partition water passages. The content may be received locally at a content capture device, and the information structure may be automatically associated with the object by the content capture device. In one embodiment, the protective coating is the evaporation or reaction product of an aqueous coating composition containing a polyvinyl alcohol polymer which may be subsequently removed by aqueous washing, thermal decomposition or combustion. A user or administrator can configure the desired action. The disclosed example method also involves configuring a processor to, during a resume process of the processor system from the low-power mode, generate a second signature based on the sample of the memory regions protected during the low-power mode.
