The present disclosure is directed to a device and method for lid angle detection that is accurate even if the device is activated in an upright position. While the device is in a sleep state, first and second sensor units measure acceleration and angular ...

An azimuth calculation device includes: a first azimuth calculation unit that calculates a first azimuth based on a satellite signal or a detection result of an external sensor; a second azimuth calculation unit that calculates a second azimuth based on an...

A rotation angle detecting device includes a resolver (1) that outputs three-phase signals (Va to Vc) based on a rotation angle of a rotary shaft (3), and an R/D converter (2) that acquires the three-phase output signals (Va to Vc) via signal lines (W2a to...

A ring laser gyro wherein a first and a second laser beam propagate with propagating directions different with each other comprises electrode areas on an optical waveguide configuring the ring laser and controls an current injected or a voltage applied to ...
