A wireless digital communication system includes a base station in communication with a plurality of user equipment mobile terminals. In the present invention, each of two side walls which is integrally provided with top wall, to which a shock is applied, has a rectangular wave shape corrugated at a plurality of corrugated sections positioned to be opposed to each other in a direction perpendicular to a direction in which the shock is applied. The sensor can be disposed in a rigid tube that is surrounded by the metal jacket. The detector may have a signal readout system that uses a delay line or, alternatively, a multichannel readout system. The cover displays the number of times a user has ever opened the container which contains medication to thereby inform the user of the user’s history of medication use with a view to protecting the user from unnecessary repeat medication and suggesting the user to take medication. The analysis device comprise a laser beam oscillation section that emits a laser beam for extracting the bodily fluid from the skin, and a detection mechanism that detects whether or not the analysis tool exists at a target position.
