PUBLIC DIGITAL SCALE PROVIDING HEALTH RELATED INFORMATION TO USERS

摘要

PURPOSE: A public digital scale is provided to give the weight of a user and information relating to health of the user with high precision by using a load detecting unit, a ROM, a key input part, and a data storing part. CONSTITUTION: A public digital scale includes a load detecting unit, an amplifier(204), a filter part(206), an analog/digital converter(208), an LCD display(224), a key input part, a changeable ROM, and a data storing part(228). The load detecting unit detects a load of a user and converts the load into an electrical signal corresponding to the load. The amplifier(204) amplifies an output of the load detecting unit. The filter part(206) removes noises from the output of the load detecting unit. The analog/digital converter(208) converts the output of the filter part(206) into a digital signal. The LCD display(224) displays the weight of the user, a graphic, and a letter. The key input part is used for inputting keys.
