Abstract :
A posture, behavior and activity recording system has been developed for monitoring health conditions and activity behavior during daily life. The system employs a dual axis accelerometer, two low-power active filters, a low-power 8-bit microcontroller and a 320 KB EEPROM. Using a two-second sampling rate, the microcontroller detects whether the patient is moving or inactive; if movement is sensed, it is recorded by the EEPROM. If the patient is at rest, posture is recorded. The activity is recorded at one-minute intervals
