The control unit 180 compares the pattern of the electrocardiogram signal received through the electrocardiogram sensor 142c with the electrocardiogram pattern of the user stored in the memory 160 in advance and controls the switch 310 in the case of coincidence, So that the communication module 116 can be connected.

Next, a noise filter 200 according to various embodiments of the present invention will be described with reference to FIGS.

Unlike the dedicated equipment for electrocardiogram measurement, the mobile terminal 100 is exposed to various noise environments. For example, when measuring the electrocardiogram through the mobile terminal 100, a text message or a telephone call may come in. At this time, a notification sound, a ring tone, a vibration, or the like may be a noise of the electrocardiogram signal. In addition, the user can measure the electrocardiogram in order to check his or her health or record the current emotional state during moving, listening to music, listening to a moving image, or in a concert hall. At this time, Noise due to noise or music reproduction may occur. Noise due to static electricity in winter may occur, and noise of 60 Hz frequency may occur due to the influence of AC AC power supply when the mobile terminal 100 is charged.

When measuring the electrocardiogram through the mobile terminal 100, a noise filter that can be applied to various noise environments is required.

In particular, when the controller 180 measures the electrocardiogram via the electrocardiogram sensor 142c, when the controller 180 detects the reception of a text message or call, the controller 180 can turn off the alarm unit 153. [

Hereinafter, a filter capable of removing other noise will be described.

As shown in FIG. 9, the noise filter 200 includes a noise detector 220 and a noise remover 230.

The noise detector 220 detects noise in the digital electrocardiogram signal. The detected noise may be a noise signal on the time axis or a noise frequency pattern on the frequency axis.

The noise removing unit 230 removes the noise detected in the digital electrocardiogram signal. In particular, when the noise detector 220 detects a noise signal, the noise remover 230 may correspond to a subtractor that subtracts the noise signal from the digital electrocardiogram signal. Also, when the noise detector 220 detects the noise frequency pattern, the noise remover 230 may be a notch filter that blocks the noise frequency pattern detected in the digital electrocardiogram signal.

The known noise source detecting section 221 detects a known noise source and outputs a noise source signal. The known noise source detecting unit 222 may correspond to a vibration sensor, an electromagnetic wave sensor, a sound source detecting unit, an AC AC power detecting unit, and the like. The vibration sensor detects the vibration and outputs a noise source signal corresponding to the vibration detection signal. The electromagnetic wave sensor senses an electromagnetic wave and outputs a noise source signal corresponding to the electromagnetic wave sensing signal. The sound source detection unit detects a sound source to be reproduced and outputs a noise source signal corresponding to the sound source signal. The AC AC power detector detects AC AC power and outputs a noise source signal corresponding to the AC AC power signal.

The comparing unit 222 compares the digital electrocardiogram signal with the noise source signal to output noise. The comparing unit 222 may output a noise signal or a noise frequency pattern.

As shown in FIG. 11, the noise filter 200 includes a noise detector 220 and a noise remover 230. The noise detection unit 220 includes an amplifier 223 and a saturated section detection unit 224.

The amplifier 223 amplifies the digital electrocardiogram signal and generates the amplified digital electrocardiogram signal.

The saturation section detector 224 detects a saturation section in the amplified digital electrocardiogram signal and detects a noise corresponding to the detected saturation section. The saturation section detecting section 224 can output a noise signal or a noise frequency pattern.

Noise caused by static electricity in winter or noise of 60 Hz frequency when the mobile terminal 100 is charged can be removed through the noise filter shown in FIG.

12 is a block diagram of a noise filter according to another embodiment of the present invention.

As shown in FIG. 12, a plurality of noise filters 200 may be connected in series. For example, the mobile terminal 100 may have a primary filter corresponding to the noise filter shown in FIG. 10 and a secondary filter corresponding to the noise filter shown in FIG.

Next, an ear-jack type photoplethysmographic signal (PPG) sensor (hereinafter referred to as a PPG sensor) according to an embodiment of the present invention and a mobile terminal 100 supporting the same will be described with reference to FIG. 13 and FIG.

13 shows an ear jack type PPG sensor according to an embodiment of the present invention.

13, an ear jack type PPG sensor 142b according to an embodiment of the present invention includes a light emitting diode 172, a light receiving diode 173, a current-voltage converter (IV converter) 720, a filter 730, an amplifier 735, and a plug 740. The plug includes a microphone signal port 740a, a first ear speaker port 740b, a second ear speaker port 740c, and a ground port 740d.

The anode terminal of the light emitting diode 172 is connected to the second ear speaker port 740c, and the cathode terminal is connected to the ground port 740d. The anode terminal and the cathode terminal of the light receiving diode 173 are connected to the two input terminals of the current-voltage converter 720, respectively. The output terminal of the current-to-voltage converter 720 is connected to the input terminal of the filter 730. The output terminal of the filter 730 is connected to the input terminal of the amplifier 735. The output terminal of the amplifier 735 is connected to the microphone signal port 740a.

14 is a block diagram illustrating additional components of a mobile terminal according to an embodiment of the present invention.

14, a mobile terminal 100 according to an embodiment of the present invention includes an ear jack 176, an audio subsystem 240, an analog-to-digital converter 250, and a switch 260. The ear jack 176 includes a microphone signal port 176a, a first ear speaker port 176b, a second ear speaker port 176c, and a ground port 176d.

The input terminal of the analog-to-digital converter 250 is connected to the microphone signal port 176a. The output terminal of the analog-to-digital converter 250 is connected to the control unit 180. One end of the switch 260 is connected to the microphone signal port 176a and the other end is connected to the microphone signal input terminal of the audio subsystem 240. [ The first ear speaker port 176b and the second ear speaker port 176c are connected to two audio output terminals of the audio subsystem, respectively.

In order for the ear jack 176 to be normally used for audio, the control unit 180 provides a control signal to the switch 260 so that the switch 260 is turned on.

When the plug 740 is inserted into the ear jack 176, the microphone signal port 740a, the first ear speaker port 740b, the second ear speaker port 740c, and the ground port 740d are connected to the microphone signal port 176a, a first ear speaker port 176b, a second ear speaker port 176c, and a ground port 176d.

Then, the light emitting diode 172 emits light by the initial voltage applied to the second ear speaker port 176c.

On the other hand, the current-voltage converter 720, the filter 730, and the amplifier 735 operate abnormally due to the initial voltage applied to the first ear speaker port 176b. That is, the light receiving diode 173 receives the light emitted by the light emitting diode 172 and generates a current signal. The current-to-voltage converter 720 converts the generated current signal into a voltage signal by an initial voltage. The filter 730 filters the voltage signal by an initial voltage to generate a filtered voltage signal. Amplifier 735 amplifies the voltage signal filtered by the initial voltage to produce an initial PPG signal.

This initial PPG signal is not an accurate blood movement measurement signal, but raises the DC level of the microphone signal port 176a.

The ADC 250 converts the initial PPG signal to digital and provides it to the controller 180.

The control unit 180 recognizes that the PPG sensor 142b is inserted into the ear jack 176 when it detects the DC level rise of the microphone signal port 176a. Then, in order for the ear jack 176 to be used for the PPG sensor 142b, the control unit 180 provides a control signal to the switch 260 so that the switch 260 is turned off.

In order to provide stable power to the PPG sensor 142b, the control unit 180 controls the audio subsystem 240 so that the audio subsystem 240 can control the first ear speaker port 176b, 176c.

When the PPG sensor 142b is supplied with a stable power source, the light emitting diode 172 normally emits light due to the DC voltage caught by the second ear speaker port 740c. Also, the current-voltage converter 720, the filter 730, and the amplifier 735 are normally operated by the DC voltage caught by the first ear speaker port 740b. Thus, the amplifier 735 provides a normal blood motion measurement signal to the microphone signal port 740a, and the ADC 250 converts the normal blood motion measurement signal into a digital signal and provides it to the control unit 180. [

Normally, when the user touches one of the plurality of electrocardiogram electrodes 171, the DC level of the electrocardiogram signal increases, but the electrocardiogram waveform does not appear. When the user touches two or more of the plurality of electrocardiogram electrodes 171, the DC level of the electrocardiogram signal increases and the electrocardiogram waveform appears.

When the DC level of the electrocardiogram signal rises, the controller 180 recognizes that an interrupt corresponding to the body contact input has occurred (S205), and transitions to the second mode M2 corresponding to the interrupt corresponding to the body contact input ( S207).

In the second mode M2, the control unit 180 confirms the detection of the electrocardiographic waveform (S209). Usually, an electrocardiogram waveform appears when a user touches two or more of the plurality of electrocardiogram electrodes 171 by hand.

In the third mode M3, the control unit 180 confirms the detection of the squeeze waveform (S215). When the user touches two or more of the plurality of electrocardiogram electrodes 171 and the user holds the mobile terminal 100 tightly, the electromyogram waveform appears because of the reason that the electromyogram signal is enlarged.

When the electromyogram waveform is detected, the controller 180 recognizes that an interrupt corresponding to the squeeze input has occurred (S217), and transitions to the fourth mode M4 in response to the interrupt corresponding to the squeeze input (S219).

In the fourth mode M4, the controller 180 determines whether the pattern of the received electrocardiogram signal matches the pattern of the electrocardiogram signal of the user (S221).

If the matching is confirmed, the controller 180 determines that the user authentication is successful and transits to the fifth mode M5 (S223).

When the user releases the tightness of the mobile terminal 100 while touching at least two of the plurality of electrocardiogram electrodes 171, the electrocardiogram waveform appears again. At this time, the controller 180 performs user authentication, and if the user authentication is successful, the controller 180 transitions from the fourth mode M4 to the fifth mode M5.

17 is a mode transition diagram according to an embodiment of the present invention.

As shown in FIG. 17, when the rise of the DC level of the electrocardiogram signal is detected in the first mode M1, the control unit 180 transits to the second mode M2.

When the electrocardiographic waveform appears in the second mode M2, the control unit 180 transits to the third mode M3. If the DC level of the electrocardiogram signal is maintained at a low level for a predetermined time in the second mode M2, the controller 180 transitions to the first mode M1.

When the electromyogram waveform appears in the third mode M3, the control unit 180 transits to the fourth mode M4. If the DC level of the electrocardiogram signal is maintained at a low level for a predetermined time in the third mode M3, the controller 180 transits to the first mode M1. If the ECG waveform is not detected for a predetermined time in the third mode M3, the controller 180 transits to the second mode M2.

When the electrocardiographic waveform is displayed in the fourth mode, the controller 180 performs user authentication, and transitions to the fifth mode M5 when the user authentication is successful. If the DC level of the electrocardiogram signal is maintained at a low level for a predetermined time in the fourth mode M4, the control unit 180 transits to the first mode M1. If the electrocardiographic waveform is not detected for a predetermined time in the fourth mode M4, the controller 180 transits to the second mode M2.

In this case, since the user authentication has been performed, the control unit 180 may not re-execute the user authentication in the fourth mode M4.

At this time, if the previous mode corresponds to the terminal locked state and the subsequent mode corresponds to the unlocked state, the user can release the locked state of the terminal by tightening the terminal. If the previous mode corresponds to the sleep state and the subsequent mode corresponds to the state deviating from the sleep state, the user can release the sleep state of the terminal by tightening the terminal. If the previous mode corresponds to the reception state of the call and the subsequent mode corresponds to the telephone call state, the user can make a telephone call by closing the terminal. If the previous mode corresponds to the message reception state and the subsequent mode corresponds to the message display state, the user can confirm the message by closing the terminal.

23 to 29, a data transmission method of a mobile terminal according to an embodiment of the present invention will be described.

23 is a flowchart illustrating a data transmission method of a mobile terminal according to an embodiment of the present invention.

It is assumed in FIG. 23 that the mobile terminal 100 is capable of communicating with the first device 400 and the second device 500, but the mobile terminal 100 intends to communicate with the first device 400.

First, the controller 180 detects occurrence of an event (S101) and waits for reception of the electrocardiogram signal. Here, the event may correspond to reception of a call, execution of a program, selection of a file to be transmitted, selection of a device to be connected, selection of a communication method, and the like. Here, the program may correspond to a contact-related program, a card-related program, a document transmission-related program, a music reproduction program, a video reproduction program, and the like. The file to be transmitted may correspond to a contact, a business card, a document, a music file, a video file, and the like.

The control unit 180 receives the communication request user input (S103). Here, the communication request user input may correspond to the electromyogram waveform.

Thereafter, the control unit 180 detects the electrocardiogram signal through the electrocardiograph sensor 142c (S105).

The controller 180 recognizes the electrocardiogram pattern from the electrocardiogram signal, and confirms whether the electrocardiogram pattern of the user stored in the memory 160 matches the recognized electrocardiogram pattern to perform the electrocardiogram authentication (S107).

If the user's electrocardiogram pattern is not stored in the memory or the electrocardiogram pattern of the user stored in the memory 160 does not coincide with the determined electrocardiogram pattern, the control unit 180 displays a password input window on the display unit 151 (S111).

The control unit 180 receives the password (S113), confirms whether the received password matches the password stored in the memory 160, and performs password authentication (S115). If the password authentication fails, the control unit 180 ends the data transmission.

On the other hand, if the password authentication is successful, the controller 180 stores the identified ECG pattern in the memory 160 to update the ECG pattern (S117). The ECG pattern update will be described with reference to FIG.
