| 20090129364 | METHOD FOR TRANSMITTING AND RECEIVING SAFETY MESSAGE - A method for a first mobile station to transmit a safety message to a second mobile station is provided. The first mobile station competitively transmits a non-safety message to the second mobile station during a first period. The first mobile station spreads a safety message and generates a spread message when a second period starts, and transmits the spread message to the second mobile station. Accordingly, safety message transmission delay or data loss in the inter-vehicle communication can be prevented. | 05-21-2009 |
| 20090232313 | Method and Device for Controlling Security Channel in Epon - A method and device for controlling security of a communication channel between an OLT and an ONU in a secure channel control system of EPON formed of the OLT and the ONU having a cryptographic module, a key management module and a transmitter/receiver for transmitting/receiving frames, the method comprising the steps of: a) distributing a key between the OLT and the ONU; b) transferring the distributed key to the encryption modules of the OLT and ONU; c) activating a corresponding encryption module using the distributed key at one of the OLT and the ONU which starts a security function activation; d) transmitting an encryption module information message including activation state information of the corresponding encryption module from the side (transmitting side) having the activated encryption module to an opponent side (receiving side); and e) activating an encryption module by checking activation state information of the encryption module at the receiving side. | 09-17-2009 |
| 20100098048 | METHOD FOR HYBRID MEDIUM ACCESS CONTROL FOR VEHICLE COMMUNICATION - A method for hybrid media access control for vehicle communication is provided. The method divides a radio channel into time slots, which are predetermined time units, and sets terminals as owners or non-owners for the divided time slots to be able to access the channel. Accordingly, it is possible to reduce the probability of contention by distributed access to the slots and provide a MAC protocol having excellent performance. | 04-22-2010 |
| 20110153155 | METHOD AND SYSTEM FOR PROVIDING IMAGE INFORMATION - A system for providing image information while interworking with a plurality of photographing apparatuses converts each of at least one image transmitted from the plurality of photographing apparatuses into a frame, and inserts the coordinates of the intersection into the converted frame. Next, the system determines whether a vehicle enters the intersection based on the frame into which the coordinates of the intersection are inserted, the current travelling direction of the vehicle, and the current position coordinates of the vehicle. The system extracts image information of the road intersecting at the frame corresponding to each of at least one image, when the vehicle enters the vehicle, and provides the extracted image information to the user through a terminal in the vehicle. | 06-23-2011 |

| 20090028543 | APPARATUS FOR PHOTOGRAPHING PIPE WITHOUT SUSPENSION OF WATER SUPPLY AND SYSTEM FOR CONTROLLING THE SAME - An apparatus for photographing a pipe without suspension of water supply and a system for controlling the same are disclosed. According to present invention, the interior of the pipe can be photographed by inserting the camera into the pipe and moving and rotating the camera without halting water supply, and information about the movement and rotation of the camera can be produced. A problem of discontinuance of using the whole pipe due to photographing of the interior of the pipe can be prevented. The camera can accurately photograph respective portions in the pipe by precisely moving forward/backward and rotating left/right or up/down. Since information about a practical position in the pipe with respect to the photographed image is provided, a user can accurately grasp a defect-position in the pipe, and can easily control the camera. | 01-29-2009 |
