An overvoltage battery protection circuit includes a voltage comparator configured to compare a scaled version of a voltage with a voltage reference and indicate an overvoltage condition when the scaled voltage exceeds the voltage reference. In certain embodiments, the beverage container further includes an informational attachment including promotional information. The first and second conflicting information describe different characteristics of a model described by the model information. A quasi incompressible thermally insulating material in the form of a gel is disposed to completely filling the annular space between the inner pipe and the outer jacket. The second payload data from the second signal is also identified at least in part with the PN array despreader. Sensitive portions of the database tables and database indexes are encrypted, ordered and searched according to Boolean functions arranged to work with encrypted data.
