Position sensor AC or DC

The device generates five output patterns that correspond to each of the following five possible body positions: Standing/Sitting, supine, prone, left and right. An example of each position code is represented below. The output voltage range is approximately 100 microvolts. The output impedance is near zero. The pattern is generated approximately every 15 seconds in supine, prone and both sides. The signal occurs approximately every two seconds in the sitting/standing position. The mini-tracker consists of a sensor and an velcro band.
