1. In an apparatus for measuring and transmitting vital signals, a system to transmit vital signals from a moving human body in the presence of dynamic external disturbance and to compensate for artifacts thereof, comprising:

  • a three axis acceleration sensor part detecting each of a X, Y, Z axis acceleration and converting it into electronic signals;

    a pre-amplifier part pre-amplifying the output from the three axis acceleration sensor part and supplying only signals within a band for digital signals processing by removing high frequency noise;

    an A/D converter converting the output signals from the pre-amplifier part into digital signals;

    a digital signals processing part determining stopped or movement conditions of a human being moving on foot or on a vehicle, by mathematically processing the three axis acceleration signals output by the A/D converter; and

    a transmitter part transmitting the result of the digital signals processing part and the three axis acceleration signals.
