Description

561413 V. Description of the invention α) 5 -1 Field of invention: The present invention relates to a wireless pressure electromagnetic induction system, and more particularly to a wireless pressure electromagnetic induction system capable of transmitting and receiving a specific frequency. 5-2 Background of the Invention: Since the handwriting recognition circuit device can replace a mouse and is more suitable for a user to input characters and patterns by manual input, the improvement of the handwriting recognition circuit device is a field that has developed rapidly in recent years. The earliest handwriting recognition circuit device can be regarded as replacing the mouse with a pen, and in order to improve the convenience of the user, the wireless pen and the tablet are usually used to replace the mouse. The pen tip usually corresponds to the left mouse button. Although traditional pen-based input products have been around for many years, similar products are focused on single-function applications such as drawing or Chinese input. The current pen-type input products are usually a wireless pressure electromagnetic induction circuit device. Referring to the first figure, it is a circuit block diagram of a conventional wireless electromagnetic induction device. The wireless pressure electromagnetic induction device includes: a cordless pen and a tablet. The wireless pen has a series of oscillating lines composed of inductance and capacitance (LC). When the pen tip is touched, a change in inductance will occur, which will cause the oscillating frequency to follow.

561413 V. Description of the invention (2) Changes. The greater the pressure on the pen tip, the greater the change in the inductance, and therefore the greater the change in the oscillating frequency, so the magnitude of the frequency change can be used to determine the amount of pressure applied to the pen tip. There are also two switch buttons on the side of the wireless pen. The transmission frequency of the pen is changed by the change of the capacitance in the inductive capacitor oscillator caused by the engagement of the keys. The change of the frequency can be used to determine the switch button pressed by the user. In addition, the tablet also includes components such as a detector, an amplifier, and an analog-to-digital converter. The central area of this type of traditional handwriting tablet is an induction loop, with unidirectional antennas arranged equidistantly in an array on both sides of the induction loop. The main purpose of this one-way antenna loop is only to receive the electromagnetic wave signals emitted by the dedicated wireless pen. When the wireless electromagnetic pen emits electromagnetic waves, the one-way antenna will receive the electromagnetic waves ’and obtain relevant data through the digital tablet through electromagnetic induction. However, the conventional wireless pressure electromagnetic induction device only has a simple function of receiving signals transmitted by peripheral devices and detecting its position. Therefore, the present invention provides a new wireless pressure electromagnetic induction system, so as to strengthen and increase the function of the wireless pressure electromagnetic induction device. 5-3 Purpose and Summary of the Invention: In view of the above background of the invention, in order to strengthen the function of the traditional wireless pressure electromagnetic induction device, the present invention provides a new wireless pressure electromagnetic induction system which can be used to increase and improve the performance of the traditional wireless pressure electromagnetic induction device.
