Embodiment
The present invention is a kind of inductive control circuit System and method in this direction of inquiring into.In order to understand the present invention up hill and dale, detailed step and composition thereof will be proposed in following description.Apparently, execution of the present invention is not defined in the specific details that the operator had the knack of of inductive control circuit.On the other hand, well-known composition or step are not described in the details, with the restriction of avoiding causing the present invention unnecessary.Preferred embodiment meeting of the present invention is described in detail as follows, yet except these were described in detail, the present invention can also implement in other embodiments widely, and scope of the present invention do not limited, its with after claim be as the criterion.
Shown in Figure 1B, it is to be the schematic diagram of induction system 100 of a control volume according to an embodiment of the invention.In this embodiment, above-mentioned induction system 100 comprises an electromagnetic induction module 120 of more than 110 actions of this electromagnetic pen of an electromagnetic pen 110 and induction.In the example shown in Figure 1A, this electromagnetic induction module 120 can be connected to a computer system 160, makes this computer system 160 and then controls the volume of at least one sound equipment 170.In another example shown in Figure 1B, this electromagnetic induction module 120 can directly be controlled to the volume of above-mentioned sound equipment 170.The present invention does not limit this induction system 100 or whether electromagnetic induction module 120 directly is connected with the sound equipment of being controlled 170.
In the embodiment that Figure 1A marks, above-mentioned induction system 100 can also comprise a program 162 that is installed on aforementioned calculation machine system 160, with the line of communication as 160 of this electromagnetic induction module 120 and computer systems.In addition, above-mentioned induction system 100 can also comprise a computer communication interface 164 that is connected to aforementioned calculation machine system 160, and this computer communication interface 164 is not exceeded there to be the entity circuit to connect.Moreover above-mentioned induction system 100 can also comprise a sound equipment communication interface 174 that is connected to above-mentioned sound equipment 170.
In Figure 1A to Figure 1B, this electromagnetic induction module 120 also comprises a loop inductance module 130, an inducted switch module 140 and a control module 150.In an example, above-mentioned loop inductance module 130 comprises a plurality of loop inductances 132 of lining up ring-type with induction position electromagnetic pen 110 thereon.Secondly, above-mentioned inducted switch module 140 comprises a plurality of switches 142 that correspond to these a plurality of loop inductances 132.This control module 150 is by the above-mentioned a plurality of switches 142 of indivedual keyings, makes its corresponding loop inductance 132 these electromagnetic pens 110 of scanning detecting.So the interface between inducted switch module 140 and the control module 150 is for two-way.Learning above-mentioned electromagnetic pen 110 when 150 detectings of this control module is with a direction or another signal when mobile in regular turn on a plurality of loop inductances 132 in the other direction, after the signal of being received is disposed, can notify above-mentioned computer system 160 and sound equipment 170 to adjust broadcast sound volume by above-mentioned computer communication interface 164 and sound equipment communication interface 174.
In another example, these a plurality of loop inductances 132 are arranged is shaped as linearity, thus electromagnetic pen 110 moving directions that 150 of above-mentioned control modules can be detected be forward direction with the back to two kinds, can be used for representative and transfer big or dwindle broadcast sound volume.In another example, these a plurality of loop inductances 132 are arranged is shaped as semicircle, so electromagnetic pen 110 moving directions that can detect of 150 of above-mentioned control modules also are two kinds, be respectively a direction or another in the other direction, also can be used for representative and transfer greatly or dwindle broadcast sound volume.So the present invention does not limit the spread geometry of above-mentioned a plurality of loop inductance 132, only need its action that can detect at least two kinds of above-mentioned electromagnetic pens 110 to get final product scope according to the invention and spirit.In present embodiment, above-mentioned inducted switch module 140 can comprise and corresponds to these a plurality of switches 142 and amplifying circuit 144 to amplify the induced signal of these a plurality of loop inductances 132, in order to the precision detecting of this control module 150.In addition, above-mentioned control module 150 can utilize software, hardware mode to carry out real work, and the present invention does not limit the reality of this control module 150 and makes mode.
Please refer to shown in Figure 2ly, it is a flow process schematic diagram of the control module 150 detecting scanning electromagnetic pens 110 that mark for Fig. 1.At first in one scan step 202, make this loop inductance module 130 continue to detect the action that scans.Whether then judge in step 204 has this electromagnetic pen 110 carrying out one first action or one second action on loop inductance module 130, if there is not the action that detects electromagnetic pen 110, then flow process is got back to step 202; Otherwise carry out a time step 206.According to the shape that a plurality of loop inductances 132 are arranged, the first above-mentioned action can be a direction and another reciprocal moving with second action.Judge in this step 206 whether this electromagnetic pen 110 corresponds to first action of amplification of volume or correspond to second control action that dwindles volume.If first action, then flow process proceeds to step 208; Similarly, if second action, then flow process proceeds to step 210.In step 208, this control module 150 is promptly learnt user's desire amplification broadcast sound volume.Otherwise in step 210, this control module 150 learns that promptly the user desires to dwindle broadcast sound volume.At last, this control module 150 is sent into above-mentioned computer system 160 and sound equipment 170 by the instruction that above-mentioned computer communication interface 164 and sound equipment communication interface 174 will amplify or dwindle broadcast sound volume.
Apparently, according to the description among the top embodiment, the present invention has many corrections and difference.Therefore need be understood in the scope of its additional claim item, except above-mentioned detailed description, the present invention can also implement widely in other embodiments.Above-mentioned is preferred embodiment of the present invention only, is not in order to limit claim of the present invention; All other do not break away from the equivalence of being finished under the disclosed spirit and changes or modification, all should be included in the following claim.
