A hollow plastic part may include at least two plastic shells connected with one another at a respective edge along at least one joining plane. The two-phase output windings are wound around a plurality of teeth of the stator, and respective numbers of turns of the two-phase output windings are obtained by using m-phase windings imaginarily defined to convert the numbers of turns of the m-phase windings into those of two-phase windings. A variable attenuation imparted by the attenuator on the light beam is determined by a position of the reflector relative to the input collimator and the output collimator, along the translation direction. The system then inspects the transit states to identify the rendezvous points between the users and the vehicle plying on the custom route. 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 method includes positioning the leadframe, first die and first clip in a vertically stacked relationship and nonsolderingly locking the first clip in laterally nondisplaceble relationship with the leadframe.
