Abstract: Disclosed are a user equipment for flashback of a database and an operating method therefor, and more particularly, a user equipment for flashback of a database and an operating method therefor, which minimize, when storing log information for a data change of a database, data included in the log information and store the minimized data in the database, provide a snapshot acquired by recovering the database at a recovery time point according to a request for flashback for the database based on the log information, and support the database to be easily recovered at a time point desired by a user while reducing a processing load for the database.

Abstract: In a real-time embedded system, if a higher-level interrupt having a higher priority than a lower-level interrupt being processed occurs, the lower-level interrupt is stopped from being processed and the higher-level interrupt is processed. Upon completion of the processing of the higher-level interrupt, delay information about the lower-level interrupt is recorded in a compensation timer register corresponding to the lower-level interrupt, and when the processing is stopped, the lower-level interrupt is restarted. Upon completion of the processing of the lower-level interrupt, the next period of the lower-level interrupt is adjusted based on the delay information recorded in the compensation timer register to compensate for the delay.

Abstract: A junction box connected to a photoelectric converter and including a body with a diode. The body includes first parts that are parallel to each other, a second part connecting ends of the first parts, and a bridge connecting the first parts. The diode is in the bridge, and the second part is spaced from the bridge to form an opening.

Abstract: A sealing member according to an exemplary embodiment of the present invention includes a first plate having a predetermined width with a plate shape, and a second plate with a plate shape connected to both ends of the first plate, wherein the first plate and the second plate have the same plate shape and form a closed line.

Abstract: For synchronization between the wireless communication device of a vehicle and a synchronization device installed on a road in a vehicle network, when the passage of a vehicle is detected, the synchronization device generates and transmits a beacon signal for synchronization. That is, a synchronization signal is transmitted to the wireless communication device of the vehicle only when the vehicle is detected by the synchronization device installed at predetermined intervals on the road.
