The present invention involves a gaming device that provides a primary game which utilizes multiple sets of identical reels. When a door is determined to be open, a notification message is wirelessly transmitted to a predetermined entity or person notifying them that the door is open. The fuel cells each include a pair of first and second plates at respective opposite ends thereof. One embodiment of the invention includes an inductance compensation circuit to compensate for the change in load inductance when the number of turns of the phase coil is switched. The signal profile of the optical signal as received by the optical receiver is determined, and compared with the predetermined signal profile to quantify any misalignment or movement of the optical signal with respect to the optical receiver. The method is preferably implemented in software, running on a standard PC or a digital signal processor, but can also be hardcoded on a custom chip.
