AI Technical Summary

Benefits of technology

This technology allows for easy operation by reducing interference from outside sources like sound or light signals that may affect the accuracy of data transmission between different devices connected through wired networks. It also improves efficiency when transmitting large amounts of data over long distances without adding extra weight compared with traditional methods such as cables connecting them together.

Problems solved by technology

Technological Problem addressed in this patented technical problem described in this text involves the difficulties associated with current methods such as those mentioned earlier (their drawbacks). Specifically, these techniques have limitations due to their own design issues including bulky equipment requiring extra space during setup work, complex calculations required, slow processing times, etc.

Embodiment 1

[0046] like figure 1 The present invention shown can be divided into stroke sensor 11, signal pen 15, blackboard eraser 16, remote controller 17 and whiteboard 18 structurally, wherein stroke sensor 11 is made up of left signal receiver 12, right signal receiver 13 and signal processor 14 compositions.

[0047] figure 2 As shown, the remote controller can be a general-purpose radio remote controller, and should have at least four buttons: button 1, button 2, button 3, and button 4, respectively representing new whiteboard, page up, page down, The whiteboard prints four remote control functions, and sends the remote control information through the modulation module 402 and the antenna 403 .

[0048] The signal pen 15 is made up of a battery 21, a mechanical switch 22, a thin film circuit board 23, an infrared emission sensor 27 and an ultrasonic emission sensor 28, wherein an infrared driving circuit 24, an ultrasonic driving circuit 26 and a microprocessor 25 are arranged ...

Embodiment 2

[0069] The monostable flip-flops 71 in the narrow pulse filters 371 and 372 can also be realized by using 8253 timing counters.

Embodiment 3

[0071] The monostable flip-flop 71 in the narrow pulse filter 371, 372 also can adopt the dedicated chip 74XX122.

Abstract

The invention relates to a remote control and radio position finding electrical white board system. The invention is composed of the strokes sensor 11, the signal pencil 15, the board eraser 16, the common writing white board 18 and the remote controller 17. The remote controller employs the general radio remote controller with at least four keys, together with the modulation module and the aerial, which transmits the remote control information. With the software interface of operating the PC remotely and wirelessly, the use can use conveniently. The influence of the external noise and the supersonic echo is eliminated, by adding the narrow pulse filter and by controlling the working period of the pulse shaping circuit. By this means, the volume of the signal pencil can be decreased.
