A gaming device that, after setting a count initially to zero, enables an input to be sent to the processor upon a player’s selection of one of a plurality of displayed choices. The food safety device comprises one or more sensors that measure at least one condition of the product andor its environment, one or more visual indicators that are configured to display a visual indication of freshness andor safety of the product. The method also includes generating at least two physical antenna signals by applying a corresponding matrix, which maps the at least two virtual antennas and the at least two physical antennas in many-to-many relation, to the at least two virtual antenna signals. The upper bound of this range is associated with a voltage safely below the level at which the device may experience damage or degradation impacting its performance in the short term or the long term.
