摘要：
The present invention generally relates to a medical device including a movable instrument (MI) which is activated only when its movement is within an optimal range of acceleration. More particularly the invention relates to a fetal heart rate monitor (FHRM) having a movable Doppler transducer which transceives ultrasound energy only when found within a certain optimal range of acceleration.
