A card edge connector for electrically connecting a circuit card to a mother board includes an insulative housing having an elongated base and a pair of supporting arms extending perpendicularly from opposite lateral ends of the base, a number of conductive terminals, and a pair of latch members disposed at free ends of the pair of supporting arms. At least one partition separates the mixing spaces into which cold and heated air can each be controllably introduced by air-flow control elements. The search algorithm involves initializing each of N three-way elements of a digital-to-analog converter for the SAR ADC to a middle reference voltage. Thus, power consumed by discharge and charge of the transistor included in the second output terminal can be reduced. The gaming device compares the first and second set of symbols to determine whether any symbols in the first set of symbols match any symbols in the second set of symbols.
