Position Determination Technology (PDT)

In addition to the use of inertial sensors technology to calculate the location data, a new method will be introduced to enhance the reliability of positioning, the Predictor-Corrector Method. If the current time is the n-th interval, then the vehicle position at (n+1)th interval will be predicted from history of position, speed and acceleration in the vector space. This is followed by any adjustments from knowledge of constraints, such as feasible locations within a section of the road map. This predictor value will be used to verify the inertial sensors measurement subsequently at the (n+1)th interval by a powerful corrector method. The inertial sensors value is known as a probabilistic variable because it is not represented by a deterministic value. When several such variables are involved in a calculation, there is no single solution and the best value is obtained by stochastic analysis. The further advantage with this analysis is the ability to identify the type of error introduced by the inertial sensors system, thus making it possible to achieve even better accuracy at the (n+2)th interval.

Inertial Navigation Technology

The latest development in MEMS technology (Micro Electro-Mechanical System) results in a series of sophisticated sensor products for inertial navigation system. These products are now both small in size and inexpensive allowing the development of a low power, small, light weight, tactical grade inertial navigation system. Traditionally, all these inertial sensors are highly inaccurate, sensitive to environmental interference and errors are accumulated quite rapidly over short period of time. The integration of these inertial sensors and our proprietary data filtering and dynamic calibration algorithms provide a highly reliable and precise platform for our vehicle tracking and navigation system.

Geometric Coding

A New Method for compressing Road Maps Memory for graphics based on pixels is demanding and becomes critical in current wireless transmission. When such images are redrawn using geometric parameters, the memory saving has been shown to be dramatic - 10 to 1000 times. Our innovative method of mapping, known as Geometric Coding, goes one step further. It makes use of a proprietary database of prescribed coded shapes and road configurations appropriate to traffic engineering to map all practical possibilities. Here the first principle is to store geometric rules in the client computer that expands the condensed transmitted data into a full-blown picture, thus minimizing transmission. The second principle is that for the server to dish out current information updated regularly, thus giving the system Dynamic Intelligence.

Data Security

In addition to the capability of implementing overall security on the wireless network, we have proprietary software for PKI and symmetrical key applications. Our unique algorithms make it possible to implement RSA applications on small devices, and our unique Prime Generator, unlike a database that eats up the scarce memory, gives you virtually an unlimited number of key sets.

Localization

Localization is the key to success in the global market. On the language side, we have proprietary multi-lingual translation engines to handle software and even user manuals effectively. In addition, we have developed a highly accurate, simple to use voice recognition engine for hands free operation such as vehicle navigation.
