Description

The body fat analyzer of using the Java programmable mobile communication terminal}

The present invention relates to a body fat measuring device using a mobile communication terminal running a Java program, and more particularly, a body fat measuring device is provided in a serial port (for charging and data communication) of a mobile communication terminal (where a Java program is executed). It is possible to connect and measure and display the body fat when needed, and to transmit the measured data to the management server and store it in the database so that it can manage the trend of changes in the body fat value. In this case, the present invention relates to a body fat analyzer using a mobile communication terminal that executes a Java program to send related data to a mobile communication terminal.

Applicant has conceived a patent application No. 10-2003-0022440 (hereinafter referred to as "selection") that can use a mobile communication terminal running a Java program as a terminal of a variety of functions and a suitable accessory device.

In the present invention, as an example of a method for using a mobile communication terminal running a Java program as a terminal having various functions and an accessory device suitable thereto, the body fat measurement is described. Describe.

Recently, due to the rapid industrialization and improvement of living standards, he has been very interested in obesity and adult diseases.

Body fat is not only a major indicator of obesity, but also a cause of adult disease. Therefore, there is a growing need to simply monitor the changes in body composition before going to a specialized clinic such as a hospital and undergoing a professional diagnosis in daily life to balance the diet or the human body.

Quantitative measurement of individual components such as water, proteins, bones and fats that make up the human body is called body composition analysis, and a device for measuring them is also called body composition analyzer.

As a method of analyzing body composition, a method using bioelectrical impedance analysis, which is inexpensive and harmless to the human body, is widely used. The bioelectrical impedance method sends a weak current into the human body to calculate the amount of body fluid, muscle mass, body fat, etc. by using the measured value of the human body's electrical resistance or electrical impedance and information such as the height, weight, age, and gender of the subject. to be.

The conventional body composition measuring apparatus and method using the bioelectrical impedance method attaches four electrodes to the hands and feet of the human body and inputs the sex, age, weight, and height of the subject, and analyzes the body composition to display the result value on the display screen and the printer. Output through In such a measurement method, there is a problem that the location is restricted.

Another conventional body composition measuring method using the bioelectrical impedance method is an electrical connection with the human body using an electrode made of a touch type using both hands. This method has the convenience of measuring impedance in a standing posture without attaching a separate electrode, but is inconvenient to carry and has a problem in storing and managing the change state of body composition.

The present invention was created to solve the above problems, the purpose of the present invention is to remove the inconvenience of carrying and use as a mobile communication terminal to run a Java program at any time without regard to the place, the mobile communication terminal if necessary The body fat measurement device can be connected to the serial port (for charging and data communication) of the body, and the body fat can be measured and displayed when needed. In this case, there is an advantage that the relevant data can be sent to the mobile communication terminal.

Another object of the present invention is to provide an accessory device with a body fat measurement sensor suitable for a mobile communication terminal running the Java platform. The display portion, which should display the existing body fat measurement contents, is replaced with the liquid crystal portion of the mobile communication terminal. At the same time, it is possible to analyze and store various data transmitted from the body fat measurement sensor and to transmit it through the mobile communication terminal by using the program operation function of Java, that is, the hardware part of the existing sensor such as display and CPU It can reduce the price of IC, memory, etc., and can provide more various services.

Perform the operation for.

The mobile terminal 400 equipped with the Java platform includes a WAP browser 410, a Java Contents Manager (JCM) program 420, a memory 430, a Java machine 440, and a Java content manager. The program 420 is driven to select and download any one of proxy files for WML or HDML, and the contents of the downloaded file are analyzed to identify a location on the network of the Java content, preferably a URL.

In addition, the mobile communication terminal 400 downloads and stores Java content for body fat measurement at a location on the identified network, and executes the Java machine 440 using the stored Java content.

In more detail, the WAP browser 410 is driven according to the driving request of the user of the mobile communication terminal 400 to read the WML page of the HTTP server 100 and display it on the display panel of the mobile communication terminal 400. As the user selects any one of the WMLs displayed on the WML page, the Java content manager program 420 is driven to control the proxy file server 120 to download the proxy file regarding the location of the Java content from the network.

The Java content manager program 420 downloads and analyzes the proxy file from the proxy file server 120 according to a driving command of the WAP browser 410, and based on the analyzed information, a location, for example, a URL, of the Java content on the network. Check the information. As the location of the Java content file is confirmed, the Java content file is downloaded from the Java content file server 130, downloaded and stored in the memory 430, and the mounted Java machine 440 is driven.

The memory 430 stores a Java content file downloaded by the Java content manager program 420, and provides the file according to a file request of the Java machine 440.

The user connects the body fat measurement accessory 500 to the serial port 450 of the mobile communication terminal, and the Java machine 440 is stored in the memory 430 according to an execution command provided from the Java content manager program 420. By extracting the Java content file and linked with the body fat analyzer accessory 500, the user checks the user's body fat data using the body fat measurement accessory 500 and the body fat measurement accessory 500 The body fat data is transmitted to the mobile communication terminal 400.

The mobile communication terminal 400 transmits information on body fat to the body fat management server 150 of the HTTP server 100 via the mobile communication network 300 and the Internet backbone network 200.
