Abstract: A wheel hub includes a wheel rim and a support. The wheel rim has an inner rim surface, an outer rim surface and a connection concave. The wheel rim is composed of a metallic layer and a carbon fiber layer. The outer rim surface has an outer wall to be the metallic layer. The wheel hub is composed of the metallic layer and the carbon fiber layer. Compared to the conventional wheel hub made of a single metallic material or a carbon fiber material, the wheel hub made of metal and carbon fiber of the present invention is light in weight, endurable, and cost-effective. The outer wall of the outer rim surface of the conventional wheel hub is easily to be damaged by an external force when in use, which result in a break of the carbon fiber to lose the strength of the carbon fiber.

Abstract: A non-contact inspecting device for a panel, which has a plurality of signal inputting sensors, a plurality of signal detecting sensors and a control circuit. The signal inputting sensors are configured in a first detecting bar, and the signal detecting sensors are configured in a second detecting bar. When the device inspects the panel, the control circuit controls the signal input sensors of the first detecting bar to provide a detecting signal and controls the corresponding signal detecting sensors of the second detecting bar to receive the detecting signal synchronously, thereby relatively reducing tact-time.

Abstract: An apparatus for inspecting and repairing a circuit defect is disclosed, which has a base; a substrate-supporting platform mounted on the base; a contact inspection module having at least one contact probe and a first driving-system that drives at least one contact probe to contact the circuits formed on the glass substrate and thereby inspect a circuit defect; a non-contact inspection module having at least one non-contact sensor and a second driving-system that drives at least one non-contact sensor to inspect the circuit defect in a non-contact manner; and a laser repair module having a laser head and a third driving-system that drives the laser head to go to the circuit defect and repair the circuit defect. A method for inspecting and repairing a circuit defect is also disclosed therewith.
