20090133467 | Robot Equipped with a Gyro and Gyro Calibration Apparatus, Program, and Method - While calibrating the position of a robot having a gyro, the robot emits a beam of light to a target wall surface, and the position of a laser point on the target wall surface illuminated by the beam of light is measured. The measured position is obtained as an initial value (S | 05-28-2009 |
20090177425 | Correction device for acceleration sensor, and output value correction method for acceleration sensor - An attitude angles calculation device ( | 07-09-2009 |
20100089155 | Sensor Unit - A sensor unit has a reference base. An acceleration sensor block and angular velocity sensor support rods are arranged on the reference base, using a bottom face and one side face of the reference base as reference faces. Three acceleration sensors, which detect accelerations that act in the directions in which an X-axis, a Y-axis, and a Z-axis extend, are fitted to three faces of the acceleration sensor block, respectively. Three angular velocity sensors, which detect angular velocities about the X-axis, the Y-axis, and the Z-axis, are fitted to boards that are fitted, via rubber bushings serving as vibration-proofing rubber members, to the angular velocity sensor support rods with screws, respectively. | 04-15-2010 |

20100290056 | Abnormality detection appraratus of optical fiber gyro - The numbers of pulses of the CW signal and the CCW signal of the optical fiber gyro during a predetermined sampling duration are detected by samplers. An abnormality determiner determines that the optical fiber gyro is normal if at least one of the pulse numbers is greater than or equal to a threshold value. If both pulse numbers are smaller than the threshold value, the abnormality determiner determines that an abnormality, such as a circuit break, a bad connection, etc., has occurred, and outputs the result of determination to an output unit. The abnormality determiner may determine an abnormality on the basis of the presence/absence of quantization noise. | 11-18-2010 |
