Continuous oil pipe hanger for velocity tubular column

The invention relates to a continuous oil pipe hanger for a velocity tubular column. The continuous oil pipe hanger comprises a continuous oil pipe, an I-shaped flange, an upper slip assembly, a lower slip assembly, an upper shell, a middle shell and a lower shell, wherein vertically penetrating central holes are formed in the upper shell, the middle shell and the lower shell; the I-shaped flange is fixedly arranged at the top of the upper shell; the continuous oil pipe passes through the I-shaped flange and the central holes of the upper shell, the middle shell and the lower shell in turn; the upper slip assembly is clamped on an inner wall of the central hole of the upper shell; the lower slip assembly is located in the central hole of the middle shell; a connecting pipe sealing set is fixedly arranged on an inner wall of the central hole of the middle shell and the lower side of a hanging supporting sleeve; at least one pair of driving pistons is arranged on the inner walls of the central holes of the middle shell and the lower shell and under the connecting pipe sealing set; an upper oil port and a lower oil port respectively communicated with the driving pistons are arranged on the side walls of the middle shell and the lower shell. The continuous oil pipe hanger has the beneficial effect of capability of hanging the continuous oil pipe.

Human motion capture device

The invention relates to a human motion capture device which comprises motion measuring units, a motion parameter estimation unit, an initialization unit, a display estimation unit and an overall integration unit; the motion measuring units are attached on all the limbs of a human body and are used for measuring the motion data and the environmental data of all the limbs; the motion parameter estimation unit deducts the motion parameters and the environmental parameters of all the limbs, and when in deduction, a self-adaptive anti-interference three-dimensional angle estimation method is adopted to deduct the three-dimensional angle values of all the limbs; the initialization unit is used for receiving and integrating the motion parameters and the environmental parameters of all the limbs, and deducting the initial operation parameters of the human body motion capture device; the displacement estimation unit is used for receiving and integrating the motion parameters and the environmental parameters of all the limbs as well as the initial operation parameters of the human body motion capture device, and deducing the displacement of the human body relative to the ground; and the parameters and the displacement of the human body relative to the ground are finally integrated together by the overall integration unit, so that the position and the gesture of the overall motion of the human body are worked out and output.
