Title:
SENSOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/020702
Kind Code:
A1
Abstract:
A sensor device (10) has a detection section (12) and a processing section (14).
The detection section (12) has a three-axis acceleration sensor (20) and a temperature
sensor (22). The processing section (14) has an acceleration vector calculation
section (30), a total acceleration calculation section (34) for calculating
the magnitude of an acceleration vector, an inclination angle calculation section
(32) for calculating an inclination angle from the acceleration vector, and
a temperature calculation section (36). The inclination angle calculation
section (32) interrupts calculation of an inclination angle when the magnitude
of an acceleration vector is different from that of gravitational acceleration.
