20110022270 | ELECTRIC POWER STEERING DEVICE AND METHOD FOR CONTROLLING THE SAME - A current command value computing section includes an integration control computing section. Based on an integration of the steering torque τ, the integration control computing section computes a steering torque integration control amount Iint*, which is a compensation component for increasing the assist force. The integration control computing section functions as a determining device that determines whether the vehicle is traveling forward in a straight line. When the determining device determines that the vehicle is traveling forward in a straight line, the integration control computing section outputs the steering torque integration control amount Iint* to an adder. The current command value computing section superimposes the steering torque integration control amount Iint* on a basic assist control amount Ias* computed by a basic assist control section, and outputs the obtained value, as a current command value Iq* corresponding to a target assist force, to an output section. | 01-27-2011 |

20100016666 | SURGICAL INSTRUMENT POSITION CONTROL APPARATUS FOR ENDOSCOPE - An endoscopic system includes a surgical instrument position control apparatus. The surgical instrument position control apparatus estimates motion of an endoscope main body with respect to a target site, based on an image picked up in conjunction with movement of an endoscope. To determine the moving amount of the surgical instrument, the surgical instrument position control apparatus calculates the amounts of operations, such as bending, rotation, and forward and backward movements, of each joint of a surgical arm section which amounts are required to move the surgical instrument from a position taken by the surgical instrument after movement of the endoscope to a surgical procedure position. The surgical instrument position control apparatus thus bends each joint to move the surgical section to the original surgical procedure position so as to hold the position of the surgical instrument every time the endoscope is moved. | 01-21-2010 |
