ELECTRONIC WEIGHT SCALE, WEIGHT MANAGEMENT SYSTEM AND WEIGHT MANAGEMENT METHOD
Technical Field The present invention relates to an electronic weight scale, and more particularly, to an electronic weight scale having a universal serial bus (USB) controller and a weight management system and method using the same.
Background Art As an importance of a health including a diet increases, health care apparatuses such as electronic weight scales are spread to almost every household.
Electronic weight scales generate digital outputs. In such an electronic weight scales, it is typical to employ a load cell which generates an analog weight signal proportional to the weight of a person to be weighed. This analog weight signal is amplified via an analog amplifier and then applied to an analog to digital converter. The digital weight signal proportional to the analog weight signal is then applied to a computing device such as a microprocessor. The computing device then converts the raw digital number into a weight.
However, such a conventional electronic weight scale has a disadvantage in that it is impossible to systemically perform a weight management, for example, to minutely check a weight variation.
In efforts to solve the problem, an electronic weight scale including a memory has been introduced. However, the electronic weight scale including a memory is high-cost and also has a limitation to using measured weight data as a health management information. Hence, a method of using a personal computer (PC) to systemically manage weight data measured by the electronic weight scale has been tried. As a result, an electronic weight scale communicable with a computer via an RSC-232C interface makes its appearance. However, the electronic weight scale communicable with a computer via an RSC-232C interface is difficult to use and does not become popular due to a low transmission rate and a narrow practical application. In addition, the conventional electronic weight scale includes a battery as a power source, and the battery is replaced frequently. Thus, it is very inconvenient. Further, if the electronic weight scale is kept in a moist place, an electrolyte of the battery can be leaked, whereupon a leaked electrolyte can damage the electronic weight scale.

FIG. 1 is a block diagram illustrating a weight management system according to a preferred embodiment of the present invention; FIG. 2 is a block diagram illustrating an electronic weight scale according to the preferred embodiment of the present invention;
FIG. 3 is a block diagram illustrating a computer according to the preferred embodiment of the present invention; and
FIG. 4 is a flow chart illustrating operation of the weight management system of FIG. 1.
Best Mode for Carrying Out the Invention
Reference will now be made in detail to preferred embodiments of the present invention, example of which is illustrated in the accompanying drawings. FIG. 1 is a block diagram illustrating a weight management system according to the preferred embodiment of the present invention.
The weight management system of FIG. 1 includes an electronic weight scale 100 and a computer 200. The electronic weight scale 100 is connected to the computer 200 via a USB cable 300. The computer 200 is connected to a health-related web server 300 through an Internet 400.
FIG. 2 is a block diagram illustrating the electronic weight scale 100 of FIG. 1.
The electronic weight scale 100 includes a load cell 110, an amplifier 120, an analog to digital (A/D) converter 130, and a microprocessor 140. The microprocessor 140 includes a USB controller 142 The load cell 110 generates an analog weight signal (i.e., direct voltage) corresponding to a weight on a weight platform (not shown). The amplifier 120 amplifies the analog weight signal and then applies to the A/D converter 130. The A/D converter 130 converts the analog weight signal to a digital weight signal and then applies the digital weight signal to the microprocessor 140. The microprocessor 140 then converts the raw digital number into a weight. The microprocessor 140 controls the USB controller 142 to transfer measured weight data to computer 200 via the USB cable 300. At this point, the weight can be observed by an observer through an output device optionally arranged, e.g., a liquid crystal display (LCD) device.
FIG. 3 is a block diagram illustrating the computer 200 of FIG. 1. The computer 200 includes a computer body 210 and a USB port 220.
The computer body 210 includes a data base portion 212 and a weight management software 214. The data base portion 212 stores weight data transferred from the electronic weight scale 100 and personal information of registered persons such as a height, an age and a sex. A user can systemically manage his/her weight using the weight management software 214. For example, the weight management software 214 is programmed to show a weight variation of a person weighed, e.g., through a graph on a monitor 230, and to show a body mass index (BMI) of a person weighed. The weight management software is also programmed to compute a body fat of a person weighed using measured weight data, a height, an age, a sex, and so on, and to show a body fat variation. As a result, a user can check his/her diet state and discriminate whether he/she is obese or not by himself/herself.
The UBS port 220 accepts the USB cable 300. When the USB cable 300 is inserted into the USB port 220, the weight management software 214 can recognize the electronic weight scale 100. Meanwhile, various input/output devices are connected to the computer 200. In
FIG. 3, the monitor 230, a keyboard 240, a mouse 250, and a printer 260 are connected to the computer 200.
The weight management system according to the preferred embodiment of the present invention can contact the health-related web server 300 through an Internet. In other words, weight data and body fat data stored in the data base portion 212 are synchronized and then are transmitted to health-related web sites 300. Therefore, the user can be provided with a service such as a health consult and a health advise from the health-related web sites 300.
FIG. 4 is a flow chart illustrating operation of the weight management system of FIG. 1. First, the electronic weight scale 100 is connected to the computer 200 via the
USB cable 300 (step S100). When a person to be weighed stands on a platform (not shown) of the electronic weight scale 100 (step S102), the weight management software
214 is automatically driven (step S104). In order to identify the person, it is determined whether the person is registered or not (step SI 06). If the person is already registered, the person designates himself (step S108). For example, the person can input his ID and password for identification. If the person is not registered, the person should register himself/herself (step S110). When a user is identified, the electronic weight scale 100 communicates measured weight data of the user to the computer 200 (step S112). As a result, the measured weight data is displayed on the monitor 230 (step SI 14), and is stored in a certain region of the data base portion 212 together with a user information
(step SI 16). Also, in the step of SI 14, a body fat of the use is computed by the weight management software 214 and then is stored in the data base portion 212. The body fat of the use is displayed on the monitor 230 together with the weight.
Accordingly, a user can continuously check his/her weight variation and a body fat variation through a graph, his/her BMI, and so on, thereby bring about a systemic weight management.
Thereafter, the computer 200 contacts the Internet 400, and the weight data and body fat data stored in the data base portion 212 are synchronized and transmitted to the health-related web sites 300 through the Internet 400 (step S 118) together with a user information. Consequently, the user can be provided with a service such as a health consult and a health advise from the health -related web sites 300 (step SI 20). In other words, the health-related consult is provided to a user through an e-mail; otherwise, the health-related consult is disclosed on the web site 300.
Industrial Applicability As described herein before, the present invention has the following advantages. Firstly, since a weight variation, a body fat variation and a BMI of a person weighed are continuously checked, a systemic weight management and a systemic health care can be performed. Secondly, due to the USB, a data transmission rate between the electronic weight scale and the computer is significantly improved. In addition, since various health- related devices can be connected to the computer, a wide practical application can be achieved. Thirdly, since the weight data stored in the data base portion can be provided to, or example, health-related web sites, the user can be provided with a service such as a health consult and a health advise from the health-related web sites. Fourthly, since a power is supplied to the electronic weight scale via the USB cable, a battery is not required, whereupon a damage resulting a leakage of the electrolyte can be prevented. Fifthly, the inventive electronic weight scale is lower in cost than that having a memory, and also there is no limitation to the number of the user to be managed.
While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and details may be made therein without departing from the spirit and scope of the invention. For example, even though it is described that the weight management software has functions to show a weight variation, a body fat variation and a BMI, the weight management software can have various health-related functions.
