摘要:
A near field communication (NFC) terminal includes a controller to synchronize data; a communication unit to communicate the data with a second terminal via NFC; and a database to store permission information pertaining to the second terminal, wherein the controller synchronizes the data if the NFC terminal is within communication range of the second terminal and the stored permission information is valid. A method for data synchronization includes establishing a connection between the terminal and a second terminal via NFC; performing authentication between the terminal and the second terminal; and if the second terminal is authenticated, synchronizing data between the terminal and the second terminal via NFC.
摘要:
A joint tong apparatus for a radiation shielding facility. A spherical ball has a through-hole. An inner spherical socket and an outer spherical socket are installed in a hole formed in a partition between a radiation-shielded room and a control room so as to enclose the spherical ball on inner and outer sides. A bar is inserted and coupled into and to the through-hole of the spherical ball. An inner joint assembly has a first housing coupled to a shielded room-side end of the bar and a first pivot member pivotably mounted on a free end of the first housing. An outer joint assembly having a second housing coupled to a control room-side end of the bar and a second pivot member pivotably mounted on a free end of the second housing. The apparatus further includes a tong assembly, a handle assembly, a tong manipulation cable, and a pair of pivot manipulation cables.
