A method of playing a wagering rummy-type card game on an electronic device wherein the object of the game is to create sets or melds of cards that each comprise exactly a straight, flush, straight flush, royal flush, andor like ranks. Under select conditions, it has been determined that statistical estimates of gain and phase imbalance can be applied to adjust signals in the quadrature signal paths of a receiver. In another embodiment, the present invention relates to a projection film that has the attributes of variable gain within the single projection film. An actuator imparts movement on the transfer carriage to overcome the transfer barrier when moving between the switch-deactuated and switch-actuated positions. The apparent resistivity values or the estimated distance may be logged and the log displayed. In a particularly preferred form, a raised bubble enveloping an alpha-numeric and formatcommand key cluster includes grooves configured to surround and form-fit only alphabetical, numeric, punctuation and symbol keys of the cluster.
