A multi-end-pumped two-mirrors nonplanar ring laser with output on single point was demonstrated.

In the light of varying feature of pull deformable parmeters ,“Bivariate interacting-control monitor step”is used to decide whether sampling will be abandoned or remained,which can make the moriter data|'s processing &pull curve's dot matrix output.

This paper mainly set forth the ways to solve the problem of the insufficient input and output points of PLC by improving wiring and programming, and these also can decrease the cost of hardware in PLC control system.

Research of the zero point output of piezoresistive pressure sensor;
