1 illustrates a block diagram of a battery pack 100 and a mobile phone main body 200 which is an example of a mobile communication terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the battery pack 100 according to an embodiment of the present invention basically includes a plurality of battery cells as a power supply source for supplying operating power to the mobile phone main body 200 and is coupled to the mobile phone main body 200. Have a possible mechanical configuration. The battery pack 100 includes an acceleration measuring unit 110 for detecting a change in movement of the battery pack 100 itself.

The acceleration measuring unit 110 includes an acceleration sensor, and detects a movement change of the battery pack 100 itself through the acceleration sensor and outputs acceleration information on the movement change. An example of such an acceleration measuring unit 110 may be Korean Patent Laid-Open Publication No. 2002-0091002 previously filed and published by the present applicant.

The configuration of the three-dimensional acceleration measurement device disclosed in the Patent Publication No. 2002-0091002 is shown in Figure 2, referring to this, first, the XY acceleration sensor 112 and XZ acceleration sensor 115 is a set (of the present invention) In the embodiment, the motion change of the battery pack itself is detected and the sinusoidal signal generated by the oscillator 111 is converted according to the motion change of the battery pack itself to generate a pulse width modulation (PWM) signal of acceleration information.

The PWM signal of the acceleration information obtained from the acceleration sensors 112 and 115 is converted into an analog signal by the demodulators 113 and 116, and then the high frequency signal is removed by the passive low pass filter 114 and 117, which is a passive element combination. In other words, the acceleration noise measured by the surrounding environment other than the human motion can be removed as the filter.

Meanwhile, the analog signal of the noise-reduced acceleration information is shown in A and B in FIG. 2, and is converted into a PWM signal which is a digital signal by the duty cycle modulator 118. That is, the duty cycle modulator 118 outputs acceleration information of one axis (X axis), two axes (X axis, Y axis), or three axes (X axis, Y axis, Z axis) in PWM form. .

Meanwhile, the acceleration information output from the duty cycle modulator 18 is input to the movement amount calculator 120 that can be chipped into the microprocessor 160. The movement amount calculator 120 calculates an acceleration value from the PWM signal according to Equation 1 below. Then, the speed is obtained by firstly integrating the calculated acceleration value, and the amount of movement for each axis is calculated by secondly integrating the obtained speed. As a result, the movement amount calculation unit 120 calculates the movement amount of the battery pack 100 in the up, down, left, and right directions. You can do it.

In Equation 1 Is the high level duration of the PWM signal, Is the period of PWM signal. Also Represents the acceleration measurement range of the acceleration sensor.

The microprocessor 160 may further include a maintenance counter 130 that counts and outputs the number of beams of the terminal user from up, down, left, and right movement amount data of the battery pack obtained by the movement amount calculation unit 120. . For reference, as a method of counting the maintenance of the terminal user, the battery pack may be counted by monitoring a direction in which the battery pack moves up (+) and down (−).

Furthermore, the microprocessor 160 receives the reward count information obtained from the reward counter 130 and calculates an exercise amount of the terminal user. Since exercise calorie information is known ahead of time, calories per step can be obtained by simply multiplying calories per step by the count reward. If you want to calculate the amount of exercise more accurately, you can map the calories burned per step according to your weight and height.

The battery pack 100 according to the embodiment of the present invention may further include a body fat measuring unit 170 for measuring the body fat of the terminal user. The body fat measuring unit 170 is a body fat sensor (+,-electrode) for measuring the body impedance, and the A / D converter for converting the measured body impedance value to digital data and outputs to the data input and output controller 150 Can be configured. For reference, the DC current source for measuring body fat may use power supplied from a battery cell, and the electrode of the body fat sensor for measuring body impedance should be mechanically arranged to be in contact with the body of the terminal user.

As described above, each data generated by the movement amount calculator 120, the maintenance counter 130, the exercise amount calculator 140, and the body fat measurement unit 170 may be described later through the data input / output controller 150.
