A CF card can be shifted in position with respect to a card connecting adapter between a position where it is projected from the housing of the card connecting adapter and a position where it is prevented from projecting from the housing of the card connecting adapter. One such apparatus includes a first die including a plurality of vertical connectors formed therethrough. The pulse generating unit generating an increasing sawtooth wave pulse may have a relatively simple circuit configuration relative to that of the pulse generating unit generating a decreasing sawtooth wave pulse, thereby reducing manufacturing costs. A static frequency converter in the form of a matrix converter converts the polyphase alternating current to a desired output alternating current, wherein the stator is a polygonal stator having external winding connections that are bridged, wherein inputs to the matrix converter are connected to end connections of the winding bars. The method of the invention includes the step of determining the level of one or more 6-mercaptopurine metabolites in the patient having an immune-mediated gastrointestinal disorder.
