Abstract: Disclosed herein is an apparatus and method for detecting a fault in a digitizer. The apparatus includes a function generator for generating test signals, a transmitting switch for transmitting the test signals generated by the function generator to a selective part or all of X- and Y-channels of a transmitting digitizer, a receiving digitizer arranged in a shape identical to that of the transmitting digitizer to be adjacent to the transmitting digitizer, the receiving digitizer receiving reception signals produced by the transmitting digitizer, a receiving switch for receiving resulting signals, generated by the receiving digitizer in response to the reception signals, from a selective part or all of X- and Y-channels of the receiving digitizer, a channel controller for controlling the transmitting switch and the receiving switch, a data collection unit for collecting the resulting signals, and an analysis unit for analyzing the collected resulting signals.

Abstract: Provided is a method for fabricating a microstructure. The method includes disposing an X-ray mask on photosensitive material and exposing the photosensitive material by radiating X-rays to the photosensitive material, etching the exposed photosensitive material, forming a mold having a micro-pattern by filing the etched photosensitive material with metal, forming a mold module by combining a plurality of molds, and forming a microstructure using the mold module.

Abstract: Provided is a method for fabricating a microstructure. The method includes disposing an X-ray mask on photosensitive material and exposing the photosensitive material by radiating X-rays to the photosensitive material using a side exposure scheme, etching the exposed photosensitive material, forming a mold having a micro-pattern by filing the etched photosensitive material with metal, forming a mold module by combining a plurality of molds, and forming a microstructure using the mold module.

Abstract: There is provided a curvature measuring apparatus and method using multiple beams. m×n multiple beams generated by an m×n laser diode (LD) array or an m×n vertical cavity surface emitting laser array having a uniform pitch are converted into multiple divergent or multiple parallel beams. The multiple beams strike and reflect from the surface of a thin film formed on a substrate Then, the multiple beams are detected by an m×n spot array in a detector such as a charge coupled device (CCD) or a CMOS image sensor. The spot spacing between the beams in the array is measured in a direction parallel to the incident plane. The spot spacing between the beams is changed by the curvature of the substrate in the direction parallel to the incident plane and the curvature may be expressed by a function including change in beam spacing, an incident angle, a distance between the surface of the thin film and the detector.

Abstract: A wireless network-based portable wireless flashing light system is based on a wireless network-based portable wireless flashing light. The wireless network-based portable wireless flashing light includes a wireless communication module, a display unit, an emergency alarm unit, and a control unit. The wireless communication module transmits and receives a wireless signal to and from an outside. The display unit displays predetermined information. The emergency alarm unit provides notification of an emergency. The control unit extracts status information about manufacturing machines from the signal received from the wireless communication module, displays information about a manufacturing machine in which an abnormality occurs on the display unit based on the status information, and operates the emergency alarm unit.
