Description

200414609 V. Description of the invention (1) 1. [Technical field to which the invention belongs] The present invention relates to an electromagnetic induction system, and more particularly, to an electromagnetic induction system and method for optimizing antenna circuit layout. 2. [Previous Technology] Since the handwriting recognition circuit device can replace the mouse and is more suitable for the user to input characters and patterns by manual input, the improvement of the handwriting recognition circuit device has been a rapidly developing field 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 electromagnetic mouse and the tablet are usually used to replace the mouse, and the tip of the electromagnetic pen is usually used to slide. Left mouse button. Although traditional pen-type input products have been available for many years, similar products are focused on single-function applications such as drawing or Chinese input. Conventional electromagnetic induction systems have a tablet and a transducer or cursor device in the form of a mouse or pen. It is well known that there are two modes of operation for determining the position of a tracing device on the surface of an electromagnetic tablet. One is a relative mode and the other is an absolute mode. Normal mouse devices operate in relative mode. As the mouse rolls across the surface of the tablet system, the computer system receives input from the mouse. Only the relative movement of the mouse in the X and Y directions can be recognized. A common technique is to use a sensing device in the mouse to form a pair of transformation signals that are perpendicular to each other, and the pair of signals corresponds to the longitudinal and lateral movement of the mouse. Similarly, cursor devices in tablet systems, such as electromagnetic pens, generally operate in absolute mode. If the cursor device is lifted and moved to another position on the surface of the tablet it supports, the signal to the computer system is

5. Description of the invention (2) It will be changed to reflect the new absolute position of the cursor device. Nowadays, there are many methods for determining the position of the cursor device on the supported tablet surface. The technology that is commonly used in absolute mode is a kind of lightning induction technology.

Earlier transducer / vernier devices were connected to a digital board via a multi-conductor cable, and the position and button / pressure information was transmitted to the computer system via this cable. In some conventional technologies, the electromagnetic transducer / cursor setting has used the frequency i / or phase change to transmit the non-azimuth state of the transducer / cursor ^ function. Usually these functions have: Button pressure 'money-like functions and so on. However, if there is no prudent handling, the change of frequency and phase can easily lead to erroneous reading signals due to various external factors, such as full-scale noise, electromagnetic waves, and so on. ; F larger tablets ’These problems will become more apparent. Biography: The technology of the tablet system allows the user to operate under dual mode operation: 1 This device can provide relative movement or absolute * under the control of the user. The current pen-type input products are usually-a kind of salt-sleeve "road device. The traditional electromagnetic induction system s

However, this layout method causes each antenna loop of the antenna layout to cross each other, which makes the antenna layout too dense, which leads to a significant increase in noise, as shown in Figure 1C. In addition, for the antenna layout of the electromagnetic induction system, in order to meet the small size requirements of modern industries, all components and antenna loops must be reduced. Especially in the antenna layout using multiple antenna loops, the loop design is more complex and the wiring is more Due to the denseness, the situation where the wires cross each other is more serious, and because all the antenna circuits are integrated in the same connector, the edge of the antenna substrate can no longer be restricted. Furthermore, when manufacturing an antenna process with a small-sized antenna layout, short-circuiting is likely to be caused due to the complicated cross-line design. Therefore, for an antenna process with an antenna layout having multiple antenna circuits, electromagnetic induction The antenna layout of the system has been difficult to break through the critical size to achieve the goal of reducing the antenna layout with multiple antenna loops. In view of the above reasons, the present invention provides an optimized antenna layout of an electromagnetic induction system to reduce cross-line design and avoid various problems caused by the reduction of antenna layout, while enhancing the performance of the electromagnetic induction system. 3. Summary of the Invention In view of the above background of the invention, in order to reduce the cross-line design and avoid the short circuit caused by the reduction of the antenna layout, the present invention provides an electromagnetic induction system with an optimized antenna layout and a method therefor to improve Cross-line design and efficiency of traditional electromagnetic induction systems.
