In an antenna diversity environment, the timing offset of the receiver’s fingers are based on the timing offset of the received peaks of the base station transmit signals. Each node includes a processing element, a software extensible device, and a communication interface. The housing defines an inlet, an outlet, a first chamber connected to the inlet, and a second chamber connected to the outlet and the first chamber by a channel. The extendable bet button may be carried by the front housing portion in an non-extended position similar to conventional gaming machines. The blower is controlled to compensate for variations in mass air flow into the system. The method also includes, at a second location, determining second location coordinates of the measuring device, and capturing a second image.
