Abstract: A brake traction control system (BTCS) using a redundancy braking system includes a main braking force adjusting device configured to control a hydraulic brake of a vehicle, a sensor unit configured to detect a driving state of the vehicle, an electronic brake electrically operating and configured to generate braking force for at least one driving wheel, and an auxiliary braking force adjusting device configured to control the hydraulic brake and the electronic brake when a failure occurs in the main braking force adjusting device, wherein the auxiliary braking force adjusting device is configured to adjust the braking force of the electronic brake provided on at least one wheel on left and right sides of the vehicle based on a detected value of the sensor unit.

Abstract: Measuring a location of a communication terminal using a wireless local area network access point based on location coordinates of the access points and global positioning system (GPS) location information of the communication terminal.

Abstract: A method and apparatus for measuring a location of a communication terminal using an access point for a wireless local area network service is provided. The method includes storing access point information collected at each location, extracting information of nearby access points collected together at a location, where information of a reference access point is collected, from the access point information, calculating a barycentric coordinate using location coordinates of the extracted nearby access points, and determining the calculated barycentric coordinate as a final location of the communication terminal.
