The present invention pertains a controlling scheme for brake torque, which is applied, as a stand-by braking torque, to wheels of an automotive vehicle upon determination that operator braking action is imminent. The high pressure air output from an air compressor is transferred through a transfer tube to pass through the cooling tube of a cooling tank. A microprocessor is operably connected to the sensor for receiving and storing signals from the actuator. The multiply-charged analyte ions are subsequently fragmented by a variety of techniques and mass analyzed. The circular needle is rotated through an angle such that the circular needle passes through a portion of the skin, thereby \u201cself-suturing\u201d the hub to the skin of the patient.
