摘要： A system and method for calibrating oscillograph channels assigns the same value to a drawing parameter of each channel. Each channel receives a signal sent by a signal generator. The oscillograph calculates a voltage difference between a standard signal voltage of a standard channel defined by a user and a signal voltage of each of the other channels. A sequence relationship between each of the other channels and the standard channel is determined. The oscillograph adjusts a deskew value of each of the other channels until each voltage difference is in an allowable range according to the sequence relationship.

摘要： A system and method for inspecting layout of a printed circuit board (PCB) provides a graphical user interface (GUI). The GUI displays a layout of the PCB. High side pins of a pulse width modulation (PWM) controller and a component connected to a high side pin are found. If the component is a metallic oxide semiconductor field effect transistor (MOSFET), the system calculate absolute a linear distance and a trace distance between a source pin of the MOSFET and a capacitor pin of a coupling capacitor connected to the source pin. If the linear distance, the trace distance and a capacitance of the coupling capacitor accord with a layout standard, the layout of the PCB is determined to be up to standard.

摘要： A robot arm includes a circular rack, an elongated first mounting member attached to the rack, and a second mounting member attached to the first mounting member. The first mounting member extends in a radius direction of the rack and moves in a circular trace along the rack. The second mounting member slides relative to the first mounting member along the radius direction, thereby defining a polar coordinate system in a plane defined by the rack to allow the second mounting member to flexibly locate at any desired positions in the plane.
