Abstract: A conical workpiece length measurement method is provided. Two laser displacement sensors are symmetrically arranged at opposite sides of a to-be-measured conical workpiece or a tooling loaded with the to-be-measured conical workpiece. Distance X0 from each displacement sensor to a bottom plane of the to-be-measured conical workpiece is calibrated. An elongated base plate is arranged at a tip of the to-be-measured conical workpiece, and the two displacement sensors measure their respective distances to the base plate. The total length of the to-be-measured conical workpiece is calculated as follows: X=X0+(X1+X2)/2, where X1 represents distance from one of the two displacement sensors to the base plate, and X2 represents distance from the other of the two displacement sensors to the base plate. Factors influencing the length measurement include calibration of the fixed length, measurement accuracy of the displacement sensor and a tilt error of the base plate.

Abstract: An embedded nonlinear cooperative pulse-controller (ENCPC) is characterized in that its control algorithm module comprises a comparison module, an identification control unit, a dynamic control unit, a steady-state control unit and a cooperative control unit. The comparison module generates control errors. The identification control unit identifies the model parameters, the time constant and the delay time. The dynamic control unit rapidly reduces the control errors, improves the rise time and decreases the overshoot of the control system. The steady-state control unit further eliminates the control errors in a steady change process and improves the control precision. The cooperative control unit coordinates and generates the final control output signal. The control algorithm module of the ENCPC enables that the ENCPC can quickly and stably eliminate the control errors with short rise time, small overshoot and short settling time.

Abstract: A container for material storage or mixing has inner wall or walls and a bottom and a top that is either fixed or removable. The inner wall has at least one or more inward elevation lines or elevated pattern formations. The elevation lines or patterns can be part of either the wall structure or a removable piece which is placed inside the container against the inner walls. The elevation line interrupts the flow or movement of content along the surface of the inner wall during mixing motion generated by a human hand or a mechanical device. The interruption creates local turbulence near the elevated line and therefore results in the content materials mixing, grinding, homogenizing, aerating or emulsifying.
