Detailed Description
In order to make the aforementioned and other objects, features, and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, a touch sensing device according to a first embodiment of the invention is disclosed, which includes a touch part 1 and an object 2. The contact 1 and the object 2 are two separate objects that are not common and are supplied by different power sources, and the object 2 is set to sense only physical contact of the contact 1. The contact element 1 and the object 2 are preferably any type of portable object, but the object 2 may be designed as any type of stationary object depending on the embodiment. The physical contact of the present invention refers to a single point single contact between the contact member 1 and the object 2.
The contact 1 includes a signal generating unit 12, a first contact pad 14 and a power source 16. The power source 16 is an independent power source, preferably a dc power source, for supplying the power required by the signal generating unit 12 during operation. The signal generating unit 12 is used for generating a specific signal S and emitting the specific signal S through the first contact pad 14; the first contact pad 14 may be formed on a part or all of the surface of the contact 1.
The signal generating unit 12 includes a signal generator 122, an encoder 124 and a transmitting terminal 126. The signal generator 122 is used for generating the specific signal S; the encoder 124 is coupled to the signal generator 122 and encodes the specific signal S, which is converted into a channelized signal in the present embodiment, and other methods can be used to encode signals in other embodiments; the transmitting terminal 126 is electrically connected to the encoder 124 for transmitting the encoded specific signal S to the first contact pad 14.
Referring to fig. 1 again, the object 2 according to the first embodiment of the present invention includes a signal processing unit 22, a second touch pad 24, a power source 26 and a touch display unit 28. The power supply 26 is an independent power supply, preferably a dc power supply, for supplying power required for the operation of the signal processing unit 22 and the touch display unit 28. The second contact pad 24 is used for receiving the specific signal S, and may be formed on part or all of the surface of the object 2. In fig. 1, the dimensions of the first contact pad 14 and the second contact pad 24 are exaggerated for convenience of illustration, but the embodiments are not limited thereto.
The signal processing unit 22 is coupled to the second contact pad 24 for identifying the specific signal S received through the second contact pad 24, and the signal processing unit 22 includes a signal processor 222 having an interference elimination unit 222A, a decoder 224 and a receiving end 226. The receiver 226 receives the specific signal S via the second contact pad 24, and the decoder 224 is used to interpret the specific signal S received via the receiver 226 and encoded by the encoder 124, that is, only the specific signal S can be transmitted to the signal processor 222; finally, the signal processor 222 identifies and processes the decoded specific signal S, and the interference removing unit 222A of the signal processor 222 is used to remove interference caused to the specific signal S when any other object physically contacts the first contact pad 14 or the second contact pad 24, such as: the interference caused by the skin current or the charges carried by the human body to the specific signal S is removed by filtering, isolating and noise attenuating, wherein one embodiment is to preset a frequency band (frequency band) for the specific signal S and isolate signals outside the frequency band, so that the signal processing unit 22 only treats the signals in the frequency band as effective signals, the frequency band is called an effective frequency band, and the signals outside the frequency band are noise attenuated and filtered to remove the interference. In addition, preferably, the interference elimination unit 222A captures at least 2 signal waveforms of the oscillation signal in the effective frequency region for signal identification, which is caused by the discrete or discontinuous specific signal S due to the contact interference, and by using the signal capture and identification, it is possible to allow the identification method of the discontinuous signal, for example, by using the voltage rise and the frequency check for identification, and recognize at least 2 signal waveforms of the discontinuous signal as the identification threshold, thereby solving the problem that the discrete or discontinuous specific signal S is not easily identified.
In an embodiment of the present invention, the specific signal S may be one of an electrical signal, a magnetic signal or an optical signal. When the specific signal S is an electrical signal, it may be a periodic signal of voltage or current, and in this case, the first contact pad 14 and the second contact pad 24 are preferably made of conductive material, so that when the first contact pad 14 physically contacts the second contact pad 24, the specific signal S can be emitted through the surface of the first contact pad 14 and received through the surface of the second contact pad 24. In addition, the first contact pad 14 and the second contact pad 24 may be made of non-conductive material, but some or all of the surfaces thereof are plated, coated, covered or wound with conductive material to achieve the purpose of conducting the specific signal S, and the conductive material is coupled to the transmitting terminal 126 and the receiving terminal 226, respectively. At this time, when the first contact pad 14 physically contacts the second contact pad 24 at least once for at least 2 electrical signal waveforms, the contact 1 can successfully trigger the object 2.
When the specific signal S is an optical signal, the optical signal is a light sensing signal, and the emitting end 126 of the contact 1 is an emitting end capable of emitting the optical signal, which generates a variation of intensity or color tone of light based on the variation of different light sources driven by the electrical signal to form a periodic signal, and emits the periodic signal through the first contact pad 14. Meanwhile, the object 2 preferably further comprises a conversion unit 228 for converting the optical signal into an electrical signal. The conversion unit 228 converts a periodic signal formed by the intensity or the color tone of the light into an electrical signal according to the change of the light signal received by the receiving terminal 226, and then decodes the electrical signal and sends the electrical signal to the signal processor 222. It is understood that, in this case, the first contact pad 14 is preferably a light source emitter, the second contact pad 24 is made of photosensitive material, and the specific signal S is emitted through the first contact pad 14 and received through the second contact pad 24. In addition, the transforming unit 228 is preferably configured with an energy intensity receiving threshold, which is the intensity of light energy sensed when the contact element 1 physically contacts the object 2, and can be used to distinguish whether the contact element 1 physically contacts the object 2.
When the specific signal S is a magnetic signal, it can be a magnetic field or a magnetic flux signal, and the emitting end 126 of the contact member 1 is an emitting end capable of emitting the magnetic field or the magnetic flux signal, and based on the change of the electrical signal, the magnetic force generates the change of the strength or the magnetic polarity to form a periodic signal, and the periodic signal is emitted through the first contact pad 14. Also, the object 2 preferably further comprises a converting unit 228 for converting the magnetic signal into an electrical signal. The conversion unit 228 converts a periodic signal formed by the variation of the magnetic force or the magnetic polarity into an electrical signal according to the variation of the magnetic signal received by the receiving end 226, and then decodes the electrical signal and sends the electrical signal to the signal processor 222. It is understood that, in this case, the first contact pad 14 and the second contact pad 24 are preferably made of magnetic conductive material, and the specific signal S is emitted through the surface of the first contact pad 14 and received through the surface of the second contact pad 24. In addition, the switching unit 228 is preferably configured with an energy intensity receiving threshold, which is the intensity of the magnetic energy induced when the contact element 1 physically contacts the object 2, and can be used to distinguish whether the contact element 1 physically contacts the object 2.
By doing so, the object 2 can not only sense the physical contact of the contact member 1, but also exclude the physical contact sensing of other non-specific objects, such as: the specific signal S is converted into a channelized oscillating signal via the encoder 124 to limit physical contact sensing of a specific object, i.e. by encoding at least one set of oscillating signals by the encoder 124 and defining at least one set of encoded oscillating signals to be triggerable for the object 2, or defining at least one set of encoded oscillating signals to be non-triggerable for the object 2, and finally by interpreting the encoded oscillating signal by the decoder 224. Since the oscillation signals set as triggerable and non-triggerable are interpreted by the specific signal S, the object 2 can be physically touched by a specific object (e.g. touch 1) with limited sensitivity.
The contact display unit 28 is configured to perform a reaction to display that the contact 1 triggers the object 2 when the first contact pad 14 physically contacts the second contact pad 24 at least once for at least a predetermined time, for example: the touch display unit 28 can be a light display unit, such as a light emitting diode or other visible light emitting component, or a sound display unit, such as a buzzer or other audible component, that is, a touch display unit that displays the touch of the contact member 1 to the object 2 by emitting light, emitting sound or emitting light and sound simultaneously.
In the first embodiment of the touch sensing apparatus of the present invention, the signal generator 122 generates a specific signal S, and the specific signal S is encoded into at least one group of channelized oscillating signals by the encoder 124, and then transmitted to the transmitter 126 and ready to be transmitted through the first touch pad 14. When the first contact pad 14 physically contacts the second contact pad 24 at least once and contacts the second contact pad 24 for at least 2 waveform times of the specific signal S, the specific signal S is received through the receiving terminal 226 through the second contact pad 24, since at least one set of oscillation signals among the channelized oscillation signals set by the decoder 224 and encoded by the encoder 124 can be used to trigger the object 2, or at least one set of oscillation signals can not be used to trigger the object 2, thereby defining specific object contact sensing or contact non-sensing; after the interference caused by the specific signal S from other objects physically contacting the first contact pad 14 or the second contact pad 24 is removed by the interference removing unit 222A, the signal processor 222 can receive the oscillation signal triggering the object 2, and then the contact display unit 28 displays that the contact 1 triggers the object 2 in a light-emitting and/or sound-emitting manner.
Referring to fig. 1a to 4b, an actual circuit diagram and an operation method thereof of the first embodiment of the invention are described in detail below, it should be understood that the circuit diagram is only an implementation manner of the invention, and in other embodiments, other circuit architectures may be used to achieve the same functions. Fig. 2a shows signals generated by the signal generator 122; FIG. 2b shows the channelized signal that is not divided by the encoder 124, and is therefore identical to the signal generated by the signal generator 122 because it is not divided; fig. 2c shows a discrete and discontinuous signal generated by the signal received by the receiver 226 due to the interference of external noise; fig. 2d shows the signal after the interference removal unit 222A has removed the interference signal, which has restored the discrete signal to a complete signal.
Referring to fig. 1a, 2a to 2b, an implementation of the circuit architecture of the signal generating unit 12 according to the first embodiment of the present invention is disclosed, and the specific signal S is an electrical signal. In the present circuit, a quartz oscillator 122a is used to provide the frequency reference for the signal generator 122, which emits a voltage signal of 1.8 megahertz (MHz) (see FIG. 2 a), in which a transistor Q 1 For switching, a D-type flip-Flop (D-type flip-Flop) 122b, which may be a type 74HC74 flip-Flop, outputs a control signal as a switching control of the power supply of the quartz oscillator 122 a. The encoder 124 utilizes a D-type flip-flop 124a, which may also be a type 74HC74 flip-flop, in conjunction with a jumper JP (jumper) for signal channelization, which in this embodiment is shown as a jumperJP's 3-4 contact is used to output a voltage signal with a frequency division (frequency division) of 1.8 mhz (see fig. 2 b), while its 1-2 contact is used to output a voltage signal with a frequency divided by 2, i.e. 0.9 mhz; the output signal channelized by the encoder 124 is the specific signal S, which is finally sent to the first contact pad 14 ready to be sent out, since the first contact pad 14 and the second contact pad 24 are conductors in this embodiment, which can be used to send out and receive the specific signal S, respectively.
Referring to fig. 1b, an implementation of the circuit diagram of the signal processing unit 22 according to the first embodiment of the present invention is disclosed, wherein the specific signal S is received by the receiving end 226 through the second contact pad 24, and then the decoder 224 performs signal frequency comparison, that is, a chip 224a of the decoder 224 performs signal frequency comparison, and the compared frequency is generated by a quartz oscillator 224b in the decoder 224 and sent to the chip through a D-type flip-flop and a jumper JP1 for frequency comparison, wherein the chip 224a needs to make the frequency 2 times of the frequency of the specific signal S in order to determine the level of the input signal in each half cycle, for example, if the specific signal S to be compared is a signal with a frequency of 1.8 mhz, the quartz oscillator 224b needs to generate a signal with an oscillation frequency of 3.6 mhz without frequency division by the jumper JP 1; however, if the jumper JP1 is set to divide the frequency by 2, the quartz oscillator 224b needs to generate a signal of 7.2 mhz. That is, the chip 224a can preset a frequency band for the specific signal S, and regard it as an effective frequency band, so that the signals outside the frequency band are isolated; on the other hand, if the specific signal S does not match the comparison signal frequency of the decoder 224, the specific signal S cannot enter the signal processing unit 222 through the chip 224a, i.e., the contact 1 cannot trigger the object 2. Similarly, when the specific signal S is a signal with a frequency of 0.9 mhz, the quartz oscillator 224b needs to generate a signal with an oscillation frequency of 1.8 mhz when the jumper JP1 is set to divide (divide by 1 and multiply); however, if the cross-over JP1 is set to divide the frequency by 2, the quartz oscillator 224b needs to generate 3.6 MHz signal.
After the specific signal S enters the signal processor 222, and when the specific signal S is disturbed by external noise to cause dispersion or discontinuity (see fig. 2 c), the interference removing unit 222A is formed by using a Logic Circuit 222A (Logic Circuit) in cooperation with a mono-stable trigger Circuit 222b as a method for allowing identification of discontinuity and dispersion signals, the identification method is used for performing a judgment through voltage rise and frequency check, and at least 2 signal waveforms of the discontinuous signals are identified as an identification threshold. Identifying at least 2 signal waveforms is accomplished by the logic circuit 222a, i.e., the logic circuit 222a can identify only when the specific signal S has two consecutive signal waveforms; wherein if the output of the logic circuit 222a is set to f (x) i ) And the output signals from QA to QD pins of the chip 224a are assumed to be x 1 、x 2 、x 3 And x 4 Then, then
Figure A20061012704000301
The relationship is shown in table 1 below.
As can be seen from table 1, only when (x 1, x2, x3, x 4) is equal to both (0,1,0,1) and (1,0,1,0), that is, two consecutive complete inputs of the high voltage signal and the low voltage signal, can be determined by the signal of the logic circuit 222a, and a high voltage [ logic reference 1 ] is outputted to operate the following circuits.
However, after the high voltage [ logic reference 1 ] signal passes through the logic circuit 222a, the time of the output as high voltage may be discretely distributed due to external interference, so that the time of the output as high voltage is relatively short, for example, in fig. 2c, the high voltage time of the complete waveform of 1.8 megahertz (MHz) is about 0.28 microseconds (micro second), if the complete waveform is interfered, the discrete and discontinuous is formed, that is, the time of the high voltage may be less than 0.28 microseconds, the time of the discrete high voltage passing through the logic circuit 222a may be extended by the monostable flip-flop circuit 222b, that is, the specific signal S after frequency checking is extended by the effective time of the signal input thereof through the voltage boosting determination, thereby the discrete specific signal S can continuously and continuously send out the stable high voltage [ logic reference 1 ] signal to the circuit connected therebehind. Thus, the specific signal S generated and transmitted by the contact element 1 can trigger the object 2 after being received and identified by the object 2.
TABLE 1
Figure A20061012704000311
Referring to fig. 3a to 3d, the circuit diagram embodiment is illustrated when the specific signal S is an optical signal, wherein the signal generator 122 and the encoder 124 of the contact 1, the decoder 224 and the signal processor 222 of the object 2 are the same as when the specific signal S is an electrical signal, and therefore, the description thereof is omitted. In fig. 3a, the emitting end 126 is mainly provided with an infrared light emitter, such as an infrared light emitting diode (IRLED). The signal generated by the signal generator 122, after being channelized, drives the infrared light emitter to convert the electrical signal into an optical signal and emit the specific signal S, and the infrared light emitter emits a light source varying at a certain frequency according to a variation in power supply of the electrical signal at a certain frequency. In fig. 3b, the receiving terminal 226 mainly has an infrared light-sensing receiving element, such as an infrared photo-transistor (IR photo-transistor), for receiving the specific signal S; the conversion unit 228 converts the signal inputted from the optical signal into a stable and clear electrical signal by using a voltage comparator (voltage comparator), such as an electrical comparator of type LM311, and makes a higher potential [ higher than a set reference ] by comparing the potentialsV 1 Can be pulled up to an accurate high potential level, or, conversely, to a lower potential (lower than the set reference V) 1 Can be lowered to an accurate low potential level, by which an analog signal transmitted from the light-sensing reception element can be processed into a digital signalSignals, as shown in FIGS. 3c and 3d, wherein FIG. 3c shows the light-sensing component before it passes to the electric comparator, and it has a set reference V 1 Fig. 3d shows the digital signal after being processed by the converting unit 228. Wherein the setting reference V 1 Is a set energy threshold, i.e. a signal exceeding this threshold indicates that the contact element 1 is physically touching the object 2, and the set reference can be adjusted according to the required sensing accuracy.
Referring again to fig. 4a and 4b, which illustrate an embodiment of the circuit diagram when the specific signal S is a magnetic signal, wherein the signal generator 122 and encoder 124, the object 2 and decoder 224 and the signal processor 222 of the contact 1 are the same as when the specific signal S is an electrical signal, and will not be described again here. In fig. 4a, the emitter 126 mainly has an NPN transistor Q2 (NPNtransitor), such as a transistor of type Q2SC 1815. After being channelized, the signal generated by the signal generator 122 drives the NPN transistor to amplify as a current gain, so as to generate a high voltage to drive the electromagnet, and the electromagnet emits a magnetic force varying at a certain frequency according to a variation in power supply of an electrical signal at a certain frequency, that is, the specific signal S.

The electric comparator 228d converts the signal inputted with the magnetic signalFor stabilizing clear electric signals, it makes higher electric potential [ higher than set reference V ] by potential comparison 1 Can be pulled up to a precise high potential level, or conversely, a lower potential (lower than the set reference V) 1 Can be lowered to an accurate low potential level, by which the analog signal transmitted from the magnetic induction receiving element can be processed into a digital signal. It can be understood that a signal exceeding this threshold indicates that the contact 1 is physically in contact with the object 2, and the set reference V 1 Can be adjusted according to the required sensing accuracy.

utilizing the second contact element to physically contact the first object at least once for at least a second predetermined time, and then the first object executes a first reaction to display that the second contact element triggers the first object;
the first contact piece, the second contact piece, the first object and the second object are independent objects which are not commonly grounded and are supplied by different power sources.
77. The method of claim 76, wherein the method performs the first and second responses using a touch display unit.
78. The method of claim 76, wherein the first and second signals are one of electrical, magnetic and optical signals.
79. The method of claim 78, wherein the first and second signals are periodic signals.
80. The method of claim 79, wherein the first contact member physically contacts the second member once for a first predetermined time of 2 of said first signal waveforms; the second contact member physically contacts the first object once, and the second predetermined time is 2 second signal waveforms.
81. The method of claim 76, further comprising the steps of:
and removing interference on the first signal and the second signal when other objects contact the first contact piece, the second contact piece, the first object and the second object.
82. The method of claim 76, further comprising the steps of:
encoding the first and second signals to define the first object to sense physical contact of only the second contact and the second object to sense physical contact of only the first contact.
83. The touch-sensing method of claim 82, wherein said encoding is such that said first and second signals are converted into a channelized oscillating signal.
84. The method of claim 83, further comprising the steps of: setting at least one set of oscillation signals interpreted by an encoder of the first contact may trigger the second object, and setting at least one set of oscillation signals interpreted by an encoder of the second contact may trigger the first object.
85. The method of claim 83, further comprising the steps of: at least one set of oscillation signals compiled by an encoder of the first contact is set to be non-triggerable for the second object, and at least one set of oscillation signals compiled by an encoder of the second contact is set to be non-triggerable for the first object.
86. The touch-sensing method of claim 76, wherein the first response indicates that the first object transmits a first trigger signal to the first contact member to cause the first contact member to perform a first response indicating that the second contact member triggered the first object; the second response means that the second object transmits a second trigger signal to the second contact element, so that the second contact element executes a second response action to display that the first contact element triggers the second object.
87. The method of claim 86, wherein the first response action is disabling the first contact to generate and send a first signal, and the second response action is disabling the second contact to generate and send a second signal.
88. The method of claim 87, further comprising the steps of:
resetting the first contact to regenerate and send a first signal; and
resetting the second contact to regenerate and send a second signal.
89. The touch-sensing method according to claim 76, wherein the first response is that the first object transmits a first trigger signal to the third object to make it execute a corresponding response action; the second response means that the second object transmits a second trigger signal to the third object, so that the third object executes a corresponding response action.
90. The method of claim 89, wherein said response action counts the number of times the first contact triggers the second object as a third object; and/or the third member counts the number of times the second contact member triggers the first member.
