Abstract:
PURPOSE: A convergence bridge apparatus and method thereof are provided to embody networking services between mobile terminals which use heterogeneous network standards by installing heterogeneous communication module. CONSTITUTION: A first mobile apparatus transmits an apparatus discovery packet to a WLAN(Wireless Local Area Network) communication module of a CB(Convergence Bridge) apparatus(S220). The CB control unit of the CB apparatus searches the first mobile apparatus included in the WLAN and bluetooth(S230). The CB control unit transmits the apparatus discovery packet through a bluetooth communication module(S240). The CB control unit receives apparatus information from a second mobile apparatus included in the bluetooth through the bluetooth communication module(S250). The CB control unit transmits the created heterogeneous device list through a WLAN communication network(S270).
Abstract:
PURPOSE: A charge and discharge control system for improving the life of the installed battery at the car is provided to minimize the load of car battery by enabling the charging and discharging of the car battery to be performed within a normal range. CONSTITUTION: An alternator(20) generates electricity using the torque of the vehicle engine(10). A battery(30) is charged by the generated electricity from the alternator. The battery is discharged through the driving of a vehicle electricity apparatus. An electrical measuring instrument(60) measures the electrical value over the alternator and the battery. First and second switches(81,82) restrict the provided electricity. A control module(70) comprises a log DB(71) and controls the first and second switches.
