Abstract: A mobile communication terminal and a method are employed to select an object in an image captured by a camera, to detect information about a current position of the mobile communication terminal, information about a bearing of the object, and information about the distance between the current position of the mobile communication terminal and the object, and to calculate the position of the object based on the information. Thus, information about an object located a distance from the current position of the mobile communication terminal can be obtained using the mobile communication terminal.

Abstract: The fractional E1 link device between a base station and a base station controller, in a link interface between the base station and the base station controller for a mobile communication system, includes: a clock converter for receiving a frame sync clock and a system clock, and converting the system clock to a clock corresponding to the number of subscribers; a processor in synchronism with the output clock of the clock converter, for interfacing transmission/reception data of the base station; a framer/transceiver in synchronism with the frame sync clock and the system clock, for framing the output data of the processor to specific time slots in conformity with a fractional E1 link, and transmitting data received on the fractional E1 link to the processor; and a multiplexer/demultiplexer for multiplexing data received from a different base station from that of the framer/transceiver, transmitting the multiplexed data on a E1/T1 link, demultiplexing data received on the E1/T1 link, and transmitting the demu

Abstract: A loop back device of a packet communication T1 network includes: a clock generating part which inputs a frame divisional clock and a reference clock, inserts a modulated clock at a predetermined position of the reference clock to generate a main clock and is synchronous to the transformed clock position to generate a system clock for generating and extracting loop back data; a loop back data inserting part which generates the loop back data and is synchronous to the system clock generated from the clock generating part to insert the loop back data into transmission data; a framer and interface part which inputs the transmission data including the loop back data outputted from the loop back data inserting part to transmit the input data to the T1 network and receives is data from the T1 network; a loop back data extracting part which is synchronous to the system clock generated in the clock generating part to extract the loop back data from reception data outputted from the framer and interface part; and a pr
