Abstract:
PURPOSE: A system and a method for automatically correcting low-temperature of a thermometer are provided to automatically control the temperature of a low temperature maintain unit, and to complete correction until the temperature is naturally risen. CONSTITUTION: A system for automatically correcting low-temperature of a thermometer comprises a low temperature maintaining unit(100), a temperature control unit(200), a temperature measuring unit(300), and a controller(400). The low temperature maintaining unit has a reference thermometer(111) and a target thermometer(112), and maintains a low-temperature state. The temperature control unit controls the temperature of the low temperature maintaining unit. The temperature measuring unit measures the temperature of the reference thermometer and the target thermometer. The controller controls the temperature control unit, and reports the measured temperature.
Abstract:
Provided are an electronic certification mark having a certification mark and Radio Frequency Identification (RFID) or Bar Code attached to the certification mark, and a method and apparatus for displaying certification information using the certification mark. The method includes reading contents and meaning of certification or certificate information in the electronic certification mark with the RFID or the Bar Code attached to a certification mark by a reader; and displaying the certification contents and meaning or the certificate information. Since the electronic certification mark enables the contents and the meaning of the certification mark or certificate to be directly checked through a recognizing device by recognizing the RFID or the Bar Code embedded on the electronic certification mark, a certified product having a desired function is efficiently selected or purchased.
