Patent ID: 7611130

Claim:
A liquid container aeration system for replenishing gases dissolved in a selected liquid present in an interior of said liquid container, said system comprising: an electrically energized liquid pump having an input selectively positionable in a reservoir liquid contained in a selected reservoir similar to said selected liquid and having an output selectively positionable adjacent said interior, said liquid pump being switchable by pump control signals at a pump controller therein between being maintained in a pumping state in which it is capable of pumping a liquid at its input through its output, if electrical power is supplied from an electrical power source to a pump electrode therein, and a quiescent state in which it is incapable of pumping a liquid at its input through its output; an electrical power consumption detector electrically connected to said pump electrode and capable of determining whether said liquid pump is drawing electrical power through said pump electrode and of providing a power draw detection signal indicating same at a detector output thereof; and a system controller electrically connected to said pump controller and said detector output and capable of determining from said power draw detection signal whether an electrical power source connected in series with said electrical power consumption detector and said pump electrode is in a condition suited to continue supplying electrical power to said liquid pump.
