The invention relates to an automatic flexible fixture which is characterized in that the fixture comprises a mounting frame and two sets of holding devices which are symmetrically installed, wherein, one set of the holding device is directly and fixedly connected with one side of the bottom part of the mounting frame while the other set of the holding device is connected with the other side of the bottom part of the mounting frame by a set of floating mechanism; the bottom parts of the two sets of the holding devices are symmetrically provided with two clamping jaws respectively. The introduction of the floating mechanism avoids the excessive positioning of the two sets of the holding devices to the clamping work pieces in the process of clamping, which can not only compensate various positioning errors and guarantee stable grasping but also avoid the damage of work pieces caused by the reasons such as over-positioning etc.; the two sets of the holding devices are respectively provided with a floating clamping jaw, which can compensate the shape errors of the surfaces of the work pieces, increase the contact surface of the fixture and the work pieces and lessen the damage of the surfaces of the work pieces.

Disclosed are an apparatus and method for adaptively compensating a position error of a resolver. The apparatus adaptively estimating a position error contained in position information of a rotor of a motor, which is digitalized by a resolver-digital converter, and subtracting the estimated position error from the measured position information of the rotor, thereby calculating compensated position information. A regression equation and a recursive least square method applied to the regression equation are used for the adaptive estimation of the position information.

The invention relates to a large allowance electronic controlling lock bolt, which is particularly applied to the lock of a retractable roof in a large stadium. The invention comprises a bolt, a first bolt support saddle, a second bolt support saddle, an electric drive pusher, a handspike support saddle, a reducing adjustment support saddle, and a bushing block; wherein, the first bolt support saddle and the second bolt support saddle are respectively fixed on two mechanisms which need locking; at least an otic placode is respectively arranged on the first bolt support saddle and the second bolt support saddle; the electric drive pusher pushes the bolt in the bushing block and ensures the bolt to be inserted into and used as the otic placode of locking ears to lock the two mechanisms.
