Abstract: A method for evaluating fraudulent data in a Usage Based Insurance (UBI) system, includes retrieving trip data for a driver from a database. A processor on a computer determines tough context incidents in the trip data. Driving behavior of the driver during said tough context incidents is compared with driving behavior of other drivers during similar tough context incidents. The trip data is identified as potentially fraudulent if the driver's driving behavior is better by a predetermined amount compared to the other drivers' driving behavior.

Abstract: A binary arithmetic coding apparatus is implemented in a video encoder chip. The binary arithmetic coding apparatus outputs a code word according to a syntax element value, and includes a look-up table (LUT), a suffix generator and a combiner. The LUT outputs a first binary string according to the syntax element value. The suffix generator performs exp-Golomb binarization on the syntax element value to generate a second binary string. When the syntax element value is smaller than or equal to a threshold, the first binary string is outputted as the code word. When the syntax element value is greater than the threshold, the combiner combines the first binary string and the second binary string to form the code word.
