Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

Abstract: A control method of a driving mechanism is provided, including: the driving mechanism provides a first electrical signal from a control assembly to the driving mechanism to move the movable portion into an initial position relative to the fixed portion, wherein the control assembly includes a control unit and a position sensing unit; the status signal of an inertia sensing unit is read; the control unit sends the status signal to the control unit to calculate a target position; the control unit provides a second electrical signal to the driving assembly according to the target position for driving the driving assembly; a position signal is sent from the position sensing unit to the control unit; the control unit provides a third electric signal to the driving assembly to drive the driving assembly according the position signal.

Abstract: A slitter having a first slide, a first driving rail, multiple round knife modules, a second slide, a second driving rail, multiple bottom cutter modules and at least a controller is provided. The round knife module is arranged on the first slide, each round knife module is provided with a first actuator geared with the first driving rail. Each bottom cutter module is arranged on the second slide corresponding to a position of one of the round knife modules, each bottom cutter module is provided with a second actuator geared with the second driving rail. Each first actuator and the corresponding second actuator are electrically connected with the corresponding controller. The round knife module and the bottom cutter module are respectively moved by individual first actuator and second actuator. While the round knife module and the bottom cutter module are moving, material could be fed between them.

Abstract: A controller for controlling power to an LED light source includes a control terminal and control circuitry coupled to the control terminal. The control terminal provides a control signal to control a transformer. A cycle of the control signal includes a charging period, a discharging period, and an adjusting period. The control circuitry controls a primary winding of the transformer to receive power during the charging period and controls a secondary winding of the transformer to discharge power to the LED light source during the discharging period. The control circuitry further varies a frequency of the control signal periodically by controlling the adjusting period.

Abstract: An adaptive controller is provided. The controller is used to control and test an actuator of auma motor operated valve (MOV). The controller has a panel for easily testing and operating the actuator coordinated with diagnostic equipments and jigs.

Abstract: The present invention provides a combined splitting blade, including a cutting ring and a fixed disc. The cutting ring is provided with a through-hole for the flange and a blade formed on the periphery. The fixed disc is partially covered on the upper and lower end surfaces around the through-hole of the cutting ring by die-casting. The cutting ring is clamped tightly. The fixed disc and the cutting ring are made of different materials. As the cutting ring and fixed disc are not prefabricated nor made of the same kind of materials, thus simplifying the fabrication process of the blade to save the cost of materials, processing and fabrication time. In addition, the combined splitting blade is fabricated by of rolling.

Abstract: Power supply circuit for LCD backlight and method thereof are disclosed in the present invention. The power supply circuit includes a power bus, a boost converter, a buck converter and a controller. The power bus supplies power to a load. The boost converter and buck converter are coupled to the power bus respectively for storing the power from the power line and restoring the power to the load. A controller is further coupled to the buck and boost converter for enable them alternatively according to a pulse width modulation (PWM) signal.
