<P>PROBLEM TO BE SOLVED: To provide a detector wherein functions of an existing electromyograph are reduced significantly and movement of muscles and nerves are simply detected without measuring signals from the muscles and nerves, so as to have the limited function for only informing the measuring person with light and sound. <P>SOLUTION: The simplified myoelectric detector includes: an electrode unit for detecting a potential difference between two points of the muscles of a subject to be measured; an amplifier for amplifying the potential detected by the electrode unit; a signal-smoothing unit for rectifying the full waves of signals from the amplifier and smoothing the signal waveform; a threshold control unit for adjusting an intensity of input signal from the signal-smoothing unit and comparing the adjusted signal with the threshold; an output unit for externally outputting when the signal of the threshold control unit is higher than the threshold; and an electric source for supplying the necessary electric power to each unit. The threshold control unit has means for adjusting the input intensity, and can adjust the intensity of the input signal so as to surpass the threshold when the potential of the muscle of the subject is actually detected. <P>COPYRIGHT: (C)2011,JPO&INPIT |
