A permanently mounted pneumatic jack (jacklift) system for motor vehicles, as well as an impact wrench for removing and installing lug nuts. The system provides a quick and safe means of lifting one or more tires off the ground for replacement of a spare or rotating the tires on a motor vehicle. The present invention comprises two or more (typically four) pneumatic jacks, a system ON / OFF switch, an air compressor, a 120-psi air tank, air lines (hoses), individual jack extend / retract switches, jack position-locking pins, safety-locking pins, and impact wrench.

The vent may be closed to set a static ear canal pressure or to generate ear canal pressure sweeps with an incidental baseline offset. The vent may be controlled to generate ear canal pressure sweeps with an intended baseline offset. The device produces ear canal pressure proportional to drive voltage, so any desired pressure versus time function can be generated by applying a coil driving voltage with the appropriate amplitude versus time function. The device operates quietly to avoid interference with aural acoustic immittance measurement, and should have a long and maintenance free life span.
