A capsule dispenser for dispensing one of a plurality of capsules includes a blister pack having a plurality of cavities, where each cavity is configured to releasably retain one of the plurality of capsules. The method is capable of generating data operable to display a first set of information in a first region of a graphical user interface, in which the data is further operable to cause a display of the first set of information while a second set of information is not displayed. If the information has changed, the method then determines whether the changed information can be described by at least one of the SPC control charts. The system is controlled to power a first anode, a second anode, or neither anodes. Air outside of the electronic equipment is taken into an inside of the second electronic device or air inside of the first electronic device is exhausted to the outside of the electronic equipment via the air intake and exhaust hole forming part, so that an amount of the air ventilated inside of the first electronic device is controlled. The upper portion is operable to interface with the slot and allow translational movement of the electronic component along the longitudinal axis.
