    Two kinds of optimal receivers have been studied in term of signal to noise ratio (SNR) gain, probability of detection and of false alarm. They are both correlation based receivers using binary pseudo random sequences, where correlation is performed numerically. This receivers are especially adapted for road vehicle collision avoidance radar systems, because they offer a high SNR enhancement and p... View full abstract»

    A real-time positioning system for a precision chemical applicator has been developed; the system is composed of a low cost GPS combined with two optical encoders. GPS has good resolution in global range, but has poor resolution in local single-point positioning. With the optical encoders, the situation is just the opposite-they have high resolution in a small range, but the accumulative error gro... View full abstract»

    The traffic congestion will get worse when more people utilize their cars for their trips. So, the number of people using the buses will also decrease. It then results in the more use of cars. Therefore, it lends to the pollution of the environment. To reduce the traffic demands and improve the environment, the Kanagawa Prefectual Police HQ developed a public transportation priority systems (PTPS)... View full abstract»
