Brief Description of the Drawings
The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:
Fig. 1 is a block diagram illustrating a battery pack apparatus and a main frame of a mobile communication terminal in accordance with a preferred embodiment of the present invention; and
Fig. 2 is a detailed block diagram illustrating an accelerometer shown in Fig. 1 in accordance with a preferred embodiment of the present invention.
Best Mode for Carrying Out the Invention
Now, preferred embodiments of the present invention will be described in detail with reference to the annexed drawings. In the drawings, the same or similar elements are denoted by the same reference numerals even though they are depicted in different drawings. In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.
Fig. 1 is a block diagram illustrating a battery pack apparatus 100 and a main frame 200 of a mobile communication terminal in accordance with a preferred embodiment of the present invention.
Referring to Fig. 1, the battery pack apparatus 100 is adapted as a power-supply unit for providing the main frame 200 with a power-supply voltage, basically includes a plurality of battery cells, and is mechanically connected with the main frame 200. The battery pack apparatus 100 further includes an accelerometer 100 for detecting a change of its own motion .
The accelerometer 110 includes an acceleration sensor, and therefore detects the change of the motion of the battery pack apparatus 100 and outputs acceleration information in response to the detected motion change by means of the acceleration sensor. A representative example of the accelerometer 110 is described in Korean Patent Laid-open Publication No. 2002-0091002, filed by the same applicant as the present invention, which is hereby incorporated by reference.
A three-dimensional accelerometer disclosed in the Korean Patent Laid-open Publication No. 2002-0091002 is exemplarily shown in Fig. 2. Referring to Fig. 2, an X-Y acceleration sensor 112 and an X-Z acceleration sensor 115 each detect a change of the motion of the battery pack apparatus (also called a set apparatus) 100, convert a sinusoidal signal generated from an oscillator 111 into another signal in response to the detected motion change of the battery pack apparatus 100, and thereby create PWM (Pulse Width Modulation) signals indicative of acceleration information.
The PWM signals having been received from the acceleration sensors 112 and 115 are converted into analog signals by demodulators 113 and 116. Passive LPFs (Low Pass Filters) 114 and 117 serving as a combination of passive elements remove high-frequency signals from the analog signals received from the demodulators 113 and 116. In more detail, the LPFs 114 and 117 can remove acceleration noise caused by a peripheral environment rather than the motion of a human being.
The analog signals indicative of acceleration information, having no noise, are denoted by reference characters A and B of Fig. 2, and are converted into PWM signals serving as digital signals by means of a duty cycle modulator 118. In more detail, the duty cycle modulator 18 outputs one-axis (i.e., X-axis) - related, two-axes (i.e., X and Y axes) - related, or three-axes (i.e., X, Y and Z axes) - related acceleration information, in the form of a PWM signal .
The acceleration information generated from the duty cycle modulator 118 is transferred to a motion-quantity calculator 120 unifiable with a microprocessor 160 as a single chip. Upon receiving the PWM signals from the accelerometer 110, the motion-quantity calculator 120 calculates acceleration using the following Equation 1 :
[Equation 1]
T ^--0.5
A(g)=^ 1 G range
Primary integration is performed on the calculated acceleration to acquire a speed, and secondary integration is performed on the acquired speed to calculate momentum of individual axes, such that the motion-quantity calculator 120 can calculate quantities of motion in four directions (i.e., right, left, up and down directions) of the battery pack apparatus 100.
With reference to the above Equation 1, T1 is a high- level duration of the PWM signal, T2 is a cycle of the PWM signal, and Grange is an acceleration measurement range of each acceleration sensor.
The microprocessor 160 may further include a step counter 130. The step counter 130 receives the right, left, up and down momentum data of the battery pack apparatus 100 from the motion-quantity calculator 120, counts the number of steps of a user carrying a mobile terminal, and outputs the counted number of steps. For reference, another example for counting the number of steps of the user is a method for enabling the battery pack apparatus 100 to monitor vertical momentum (i.e., up(+) and down(-) momentum). Further, the microprocessor 160 receives the counted number of steps from the step counter 130, and calculates momentum of the user. The momentum calculator 140 has previously recognized consumption calorie per step information, such that it can calculate momentum data by multiplying the recognized consumption calorie per step information by the counted number of steps. For the purpose of acquisition of more correct momentum data, specific consumption calorie per step information a step may be previously mapping-processed with the weight and height of the user.
The battery pack apparatus 100 may further include a body fat measurement unit 170 for measuring body fat of the user carrying a mobile terminal . The body fat measurement unit 170 includes a body fat sensor and an A/D converter. The body fat sensor contains positive (+) and negative (-) electrodes, and measures physical impedance of the user. The
A/D converter converts the measured physical impedance into digital data, and outputs the digital data to the data I/O
(Input/Output) controller 150. For reference, a DC current source for such body fat measurement may use a power-supply voltage provided from a battery cell, and the positive and negative electrodes of the body fat measurement unit measuring the physical impedance must be mechanically arranged to be attached to the user's body. Individual data created from the motion-quantity calculator 120, the step counter 130, the momentum calculator 140, and the body fat measurement unit 170 is transmitted to the main frame 200 of the mobile terminal through the data I/O controller 150 and a main frame l/F unit 180, such that the main frame 200 displays the received data for the user's recognition. The data I/O controller 150 is adapted to control right, left, up and down motion-quantities of the battery pack apparatus 100, and is also adapted to control the output of internal data. Preferably, the data I/O controller 150 selects either one of data requested by a controller 220 of the main frame 200, for example, right, left, up and down motion-quantities data, information indicative of the counted number of steps, momentum data, or body fat measurement data. The battery pack apparatus 100 may further include a main frame l/F (Interface) unit 180 for interfacing the data I/O controller 150 with the main frame 200.
The battery pack apparatus 100 is connected with the main frame 200 of the mobile terminal. The main frame 200 of the mobile terminal will hereinafter be described in detail with reference to Fig. 2.
RF unit 230 modulates information generated from the controller 220, modulates a frequency of the information, and wirelessly transfers the modulated signal over an antenna ANT. The RF unit 230 separates a signal other than voice or audio data from the RF signal received over the antenna ANT, performs frequency conversion and frequency demodulation on the separated signal, and transmits the resultant signal to the controller 220.
Voice processor 240 performs digital processing on a voice or audio signal transmitted to a microphone MIC upon receiving a control signal from the controller 220, transmits the digitally-processed signal to the RF unit 230, demodulates voice data received via the RF unit 230, and outputs the demodulated signal via a speaker SPK. User l/F unit 250 includes a keypad and a display, creates key data in response to data entry operation of the keypad, transmits the created key data to the controller 220, and displays data controlled by the controller 220.
The controller 220 controls a system on the basis of control program data stored in an internal memory. For example, upon receipt of a user's request, the controller 220 may request the battery pack apparatus 100 either to measure body fat, or to calculate momentum, and outputs response data to this request over the user/IF unit 250. The battery I/F unit 210 is connected with the main frame l/F unit 180, and performs data communication between the battery pack apparatus 100 and the main frame 200.
The case where the battery pack apparatus 100 is connected with the main frame 200 of the mobile terminal will hereinafter be described in detail. Prior to describing the present invention, it should be noted that an application program for supporting data communication between the main frame 200 and the battery pack apparatus 100 must be previously installed in the main frame 200. Provided that the application program is installed in the main frame 200, the user may use the main frame 200 connected with the battery pack apparatus 100 as a step counter or a body fat measurement device.
1) In the case where the mobile terminal connected with the battery pack apparatus is adapted as the step counter:
The user sets the battery pack apparatus 100 to a step counter using the user l/F unit 250 of the main frame 200. In this case, the controller 220 of the main frame 200 transmits a step-counter setup command to the data I/O controller 150 of the battery pack apparatus 100. The data I/O controller 150 of the battery pack apparatus 100 transmits step-number counting information received from the step counter 130 to the main frame 200 over the main frame l/F unit 180. The controller 220 of the main frame 200 can display the received information on a display of the user l/F unit 250.
Therefore, the user can monitor the number of steps counted up to the present time using a display contained in the main frame 200. If the user wants to receive momentum data calculated up to the present time, the data I/O controller 150 receives momentum data based on current step- number counting information from the momentum calculator 140, and transmits the received momentum data to the main frame 200, such that the controller 220 contained in the main frame 200 displays the received momentum data on the display of the

2) In the case where the mobile terminal connected with the battery pack apparatus is adapted as the body fat measurement device:
The user sets the battery pack apparatus 100 to a body fat measurement unit using the user l/F unit 250 of the main frame 200. In this case, the controller 220 of the main frame 200 transmits a setup command for the body-fat measurement unit to the data I/O controller 150 of the battery pack apparatus 100. If the battery pack apparatus 100 is determined to be a body fat measurement unit, the data I/O controller 150 flows a predetermined current between the positive (+) electrode and the negative (-) electrode of the body fat measurement unit to measure physical impedance of the user. AD conversion is performed on the measured physical impedance, and the digital physical impedance data is transmitted to the main frame 200, such that the controller 220 contained in the main frame 200 can calculate the ratio of body fat using various user data (e.g., weight, height, and gender data, etc.) and the digital physical impedance. Such a method for calculating the ratio of body fat may be adapted for the battery pack apparatus 100. For reference, this method for calculating the ratio of body fat may use either one of a variety of body-fat measurement algorithms well known to those skilled in the art.
As describe above, the user can selectively use the main frame 200 connected with the battery pack apparatus 100 as a body fat measurement device or a momentum calculator.
Industrial Applicability
As apparent from the above description, the present invention can enable a battery pack apparatus containing an acceleration sensor to be adapted as a step counter, can measure momentum and body fat data of a terminal user using the number of steps counted by the step counter, and can display the measured momentum and body fat data.
Although the present invention has been described in connection with specific preferred embodiments, those skilled in the art will appreciate that various modifications, additions, and substitutions to the specific elements are possible, without departing from the scope and spirit of the present invention as disclosed in the accompanying claims.
