Abstract: An inrush current recording module is installed in a power supply unit. The power supply unit has a front-stage power circuit and a back-stage power circuit. The front-stage power circuit includes a first ground terminal, and the back-stage power circuit includes a second ground terminal. The inrush current recording module includes a series circuit and a detection recording unit. The series circuit is formed by a capacitor and a resistor, and includes two ends thereof respectively connected to the first ground terminal and the second ground terminal. The detection recording unit detects the resistor to generate a voltage signal, compares the voltage signal with a voltage determination level, starts timing an inspection period when the voltage signal is greater than the voltage determination level, and records whether a current inrush current is harmful or harmless according to whether a power output signal is obtained within the inspection period.

Abstract: A method for forcibly resetting a microcontroller is provided. A switching module is provided to power a microcontroller. The switching module detects through the control pin whether a notification port of a load connected to the control pin changes its potential level in response to a communication error between the load and the microcontroller detected by the load. When the switching module learns the change in the potential level of the notification pin, a powering status of the switching module is switched to stop powering the microcontroller to cause the microcontroller to stop operating. It is detected through the control pin whether the load again changes the potential level of the notification port in response to the microcontroller having stopped operating. When the change is detected, the powering status of the switching module is switched to again power and reactivate the microcontroller.

Abstract: A method and structure improves the dynamic characteristics of a linear roller guideway for precision machine tool, robot or automation equipment by: adding a nonlinear component to the linear roller guideway to provide better dynamic stiffness and damping effects. The nonlinear component has a nonlinear contact characteristic of hardening so that during mounting or in a quick movement of the slide units of the linear roller guideway, the nonlinear component has a relatively lower stiffness to reduce its friction with the rail surface; on the other hand, when bearing a load or during a cutting work, the nonlinear component has a relatively higher stiffness. The nonlinear component also provides a planar contact, overcoming the drawbacks of low damping of point or line contact of the slide units of the nonlinear roller guideway, and enhancing the cutting precision of the machine tool.
