1. An acceleration-monitoring device comprising:

  • a system unit disposed proximate to a body part of an individual at a first location, said system unit constructed and arranged to remain substantially fixed relative to said body part while said individual engages in physical activity, wherein said system unit includesa first accelerometer disposed along a first acceleration-monitoring direction, anda second accelerometer disposed along a second acceleration-monitoring direction,said first and second acceleration-monitoring directions being substantially orthogonal to each other;

    a third accelerometer disposed proximate to said body part of said individual at a second location displaced a distance from said first location, said third accelerometer constructed and arranged to remain substantially fixed relative to said body part while said individual engages in physical activity, said third accelerometer being disposed along a third acceleration-monitoring direction which is substantially orthogonal to a plane defined by said first and second acceleration-monitoring directions; and

    a power supply attached to said individual constructed and arranged to remain attached while said individual engages in physical activity, said power supply being electrically attached to said system unit and said third accelerometer to supply electrical power,wherein said acceleration-monitoring device is free from protruding wires and free from attachments which would tend to impede or alter physical activity of said individual, andat least one of said accelerometers provides an output signal corresponding to a range of accelerations of said body part.
