Title:
DROP DETERMINING APPARATUS AND DROP DETERMINING METHOD
Document Type and Number:
WIPO Patent Application WO/2012/169051
Kind Code:
A1
Abstract:
A drop determining apparatus (10) has a sensor unit (11), an impact calculating unit (13), and an application processing unit (14). The sensor unit (11) detects acceleration within the predetermined range. The impact calculating unit (13) calculates acceleration outside of the predetermined range using the acceleration detected by means of the sensor unit (11). The application processing unit (14) determines whether dropping occurred or not using the acceleration calculated by means of the impact calculating unit (13). Consequently, the drop determining apparatus (10) determines whether dropping occurred or not using a low-range acceleration sensor.
