Abstract: A tire monitoring system may include: a state information collecting device installed in a first tire of a vehicle, and periodically transmitting unique identification information according to a rotation period of the first tire; a plurality of wheel speed sensors of which position information is changed according to rotations of a plurality of second tires installed in the vehicle; and a monitoring device for receiving the unique identification information from the state information collecting device, detecting position information of the respective wheel speed sensors according to a receiving time of the unique identification information for a predetermined time, and identifying a position of the first tire based on fluctuating patterns of position information of the respective wheel speed sensors detected according to the receiving time of the unique identification information.

Abstract: An apparatus and method for determining a network delay and scheduling a service based on the delay are provided. The method includes determining information about a first time at which data is transmitted, determining information about a second time at which the data is received, determining a time delay using the first time and the second time, and scheduling a service based on the time delay. Because scheduling of service is based on a determined time delay, radio resources are more efficiently used.

Abstract: A synchronization apparatus and method in a mobile communication system.

Abstract: Disclosed is a system and a method for offering a broadcast service in a wireless communication system. A mobile telecommunication system for providing broadcast-multicast services includes a serving access network system for transmitting broadcast traffic and an overhead message including information relating to broadcast for at least a neighboring access network system; a neighboring access network system for receiving a transmission request for the broadcast traffic from the serving access network system and transmitting the broadcast traffic; and an access terminal for receiving the broadcast traffic from the serving access network system and the neighboring access network system.

Abstract: A method for detecting the leading and trailing ends of a video tape, which is capable of achieving an accurate detection without using any separate detecting means.

Abstract: A method for controlling tape running in a tape driving apparatus in which the size of a hub is determined when a tape is inserted into the tape driving apparatus and the number of reference pulses corresponding to one rotation of the reel in an end position of the tape is calculated according to the determined size of the hub. The tape is run and the frequency of rotation of the reel is detected. A comparison is made between the number of pulses of the present reel and the number of reference pulses, and if the number of pulses of the present reel is smaller than the number of reference pulses, the running mode is continuously performed. If, however, the number of pulses of the present reel is larger than the number of reference pulses, then a stop position is judged and the tape running is stopped, resulting in entering into a stand-by mode.
