Electronic circuit will be controlled many inputs usually.This can realize by increasing one or more multiplexers, and it can be changed by each detecting device simply in turn or use more complicated algorithm based on common or the most up-to-date detecting device.
In some applications, can need hard resilient panel.In such application, the caused distortion of customer interaction is small.These little distortion can be amplified by multiple mechanical means.Fig. 6 illustrates and is used for by using bar 8 to amplify the cross section view of arrangement of the little distortion of hard panel 1.Bar 8 is preferably made by the tongue or the cantilever of PCB material, the back side of its touch panel 1.Target 3 for example copper dish is attached to bar 8.Bar 8 extends from the button area back.The back side of protrusion 9 touch panels 1 on cantilever, the user contacts the there probably.Other mechanical hook-up comprises, for example, forms the dish of dish-shaped shape when it is pressed near its central authorities.

Fig. 7 illustrates the detecting device on the endless belt of being placed in that according to a second embodiment of the present invention extension touches the detecting device form, and wherein the user can apply power at the point along straight line, curve or circle.Such annular arrangements has been used for portable music player.Maximum distortion occurs in the user applies power along circle place.Be out of shape extensible several detecting devices of crossing.The position that relatively can be used for calculating the power of applying from the reading of each detecting device.In such structure, it is favourable so that bigger difference to be provided between adjacent detecting device that continuous target 3 is separated into several single targets 3.
Alternate embodiment of the present invention is operating rod (joystick).Operating rod is attached to panel 1 so that the interaction of user and operating rod (comprise and moving upward) makes panel deformation.Interaction can be by relatively being sensed from the reading of a plurality of detecting devices on a plurality of points that are placed in panel.
An embodiment more of the present invention is that detecting device centers on the touch-screen that its edge is settled.Input from a plurality of detecting devices is used for determining the input of user on screen.For example, four detecting devices can be arranged in each angle of the screen that remains on resilient bezel.Can calculate by the reading of four detecting devices relatively at the finger position of the difference of screen.This can carry out as question blank by the data of using the teaching pattern to obtain then in the electronic memory when beginning.
Fig. 8 illustrates the cross sectional view of another embodiment again of touch-screen of the present invention or plate form.The user makes layered target 3 distortion behind display 10, and the reading of the two-dimensional pattern by relatively coming self-detector detects the position of user's input.Detecting device can be placed on the multilayer of circuit board and is overlapping.Target 3 can be multi-disc target 3 in the two-dimensional pattern or continuous sheet.Advantageously, the performance of detecting device is independent of the chemical composition of screen in fact and what carry out electrically is what on screen.This is favourable to organic emission and plastic electronic types of display, because display and detector array can produce by printing.
Embodiments of the invention can be used for measuring the displacement that strides across bigger distance, and it is by at panel 1 with move between the main body 12 of big distance and settle spring 11.Fig. 9 illustrates the cross sectional view of such arrangement.Along with main body 12 is displaced to more near panel 1, distortion will be big, because spring compresses tightly, vice versa.That spring 11 can be settled so that when its away from the time it will draw rather than push away panel.Such arrangement is useful for displacement, vibroshock and the air of measuring piston in the cylinder or the displacement of fluid damper.
Many arrangements that can be used for the inductance element of inductive detector are arranged, and it is by using the different permutations and combinations of coil, winding, target, electric media, resonance target etc.For example, described so far target 3 can substitute with short circuit passive electric circuit or the AC winding of energizing.Arrangement can be operated by using with respect to the coefficient of self-induction of distortion or the variation of coefficient of mutual inductance.

In the system that uses multi-detector, the effect of electrical noise or vibration can be got rid of by the common mode inhibition algorithm that utilization is included in the software.In this algorithm, the total reading of a plurality of detecting devices is left in the basket, and sends and have only those detector readings that are different from other detecting device to be used as signal.
In button 1, the feature of single user's input can for example be depressed time, time of return etc. by teaching.The feature that personnel are held in place finger also can be by teaching.Moreover the size of power also can be input to host computer system to increase or to reduce controlled variable change rate.
When the Deformation Height localization, sub-fraction target 3 may only be arranged towards inductor 4 distortion.In this case, preferably avoid and to make all targets 3 with respect to the low signal due to the mechanical arrangement of inductor 4 motion.In Fig. 2, target 3 is can centrepin in place rather than stride across its whole zone and adhere to.As a result, any distortion can make entire target 3 displacements.
Although use user's finger 2 among the embodiment formerly,, stylus, pen, key or other instrument also can cause distortion.The user also can apply power by any part of using its health.
Preferably, electronic circuit is positioned near inductor 4 to avoid any Electromagnetic Compatibility problem.Ifs circuit exceedance cm distance should use circlet shape area conductor to settle to avoid the EMC problem so between circuit and detecting device.This can finish by using twisted-pair cable; Settle trace on the internal layer of the PCB5 that different layers or the location trace of PCB5 at its skin is copper face.
Although preferred panel material will can be too not hard,, have been found that and also can use for example glass of quite hard material, as long as it is as thin synusia.For example, the key work of 0.3 millimeter glass and 25 millimeters pitches is good.In order to produce bigger distortion, panel 1 needn't be in its whole side attachment.
In some were settled, if panel 1 fully conducts, independent transport element 3 was optional, and it can be used as the panel 1 and the target 3 of combination.In health very important use, copper or silver are particularly advantageous, because the user interface made from these materials 1 has superior antibacterium or antimicrobial attribute.
