摘要: The present invention relates to a radio frequency identification (RFID) tag installation system using a vehicle and method thereof. The RFID tag is installed on the road to provide a driver with position information and road information such as speed limit, road name. etc in his or her traveling region. By using our present invention, RFID tag can be installed with small manpower in short a time. The system uses two CCD cameras, two GPS receivers, an INS and a DMI, and includes: a vehicle position and yaw extractor by using the two GPS receivers; orientation extractor for the vehicle by using INS, a GPS/INS/DMI integrator for GPS outage and for INS error correction; two cameras interior/exterior orientation extractor for the CCD cameras; a target position extractor for finding 3-dimensional coordinates; a road information storage for supplying road information such as a speed limit and a rout number of a road; an RFID tag writer for inputting the information obtained from the target region position extractor and the road information storage; and an RFID tag installer for attaching the RFID tag on the road.

摘要: A circuit for driving a gate of a power metal-oxide semiconductor field effect transistor (MOSFET), which uses a higher voltage than a gate controller is provided. The circuit is able to safely and effectively transmits an output signal of a gate controller irrespective of a frequency and a duty-cycle of the output signal when transmitting the output signal of the gate controller to the power MOSFET using a higher voltage than the gate controller. Accordingly, the circuit is suitable for a case where the duty-cycle of the output signal of the gate controller dramatically changes and the frequency is irregular.
