Embodiments are directed towards employing compressed journaling for event tracking files for metadata recovery and replication. The multifunctional enclosure is configured to prevent the elongated member of the medical probe from swinging and becoming damaged during transport. The first and fourth fasteners may also be fastenable to and releasable from each other to releasably secure the sling to the waist band when the pillow is not present, to immobilize the arm at a non-abducted position. The light amplifying element or elements may comprise an array of phototubes, a multianode phototube, or a multichannel plate based image intensifier coupled to an array of photodiode detectors. Thus, there is provided an engine intake control system having an excellent assemblability and an improved accuracy of throttle valve opening degree. The determination is executed at one of the stages of selecting a tracing direction by an automatic tracing process, selecting an approximate Doppler waveform as an analysis target, and selecting an analysis result as a display target.
