A sensing device of a true-simulating bullet magazine is disclosed. Embodiments use various techniques to create fingerprints of content traversing the links of the communications system. A ratio of water-generation amount at rated output point of the membrane-electrode assemblyvolume of the first ionomer in the first electrode is 1350 or larger. Thus, damage to other generator components is greatly reduced because the generator is removed for maintenance in a timely manner. The driver is operatively coupled between the device housing and the carrier body to urge the carrier body with a controlled force and speed from the retracted position toward the advanced position to place at least a portion of the at least one piercing member of the insertion set thorough the skin of the patient to install the insertion set to the patient. The information processing apparatus includes an acquisition unit for acquiring at least one device identification information item including a plurality of configuration information items corresponding to each of a plurality of logical interfaces in response to connection of a peripheral device.
