interllective whiteboard

¢°Board separated from card technology: it put all chip of the plate circuit and control circuit into the outside box that can be dismantle to form the separation between the board and card. when there has malfunction, you only need mail the control box to service station, so that avoid repairing the boardÿ®s body, reduce transportation, make convenient for the user, especially the foreign user, which offer the favorable conditions for the foreign trade.
2. NANHAO loop dynamic tracking software technology: which depend on software to form a loop scanner by recognizing the scope of the moving hand, that sharply improves the response speed and operational sensitivity of whiteboards.
3. NANHAO adaptive Pen posture technology: According to fuzzy logic control algorithm, it can adjust operation automaticly, make the circuit parameters in a high state, avoid the influence of writing accuracy by the posture of pen.
4. R&D a saving power and sleeping pen: electronic pen can be automatic power off after spare five minutes and battery life is of 4 or 5 times than similar products.
5. Independently develop three-in-one intelligent film: at frist, it can work and have trouble-free for 300 thoustand times. secondly, it not only reduces luminous spot , protects our eyes , but also reduces the purchasing cost of projector. Thirdly, all sorts of color pens can write directly and wipe cleanly. namely, It will be instead of blackboard, projection screen and whiteboards, so called three-in-one intelligent film.
