Abstract: A measurement apparatus detects a voltage change in a power storage device. The measurement apparatus supplies constant current to the power storage device; measures voltage related to the power storage device supplied with the constant current; and detects the voltage change in the power storage device subjected to the measurement. The measurement apparatus also acquires the voltage change in the power storage device based on an electrical property serving as a reference of the power storage device.

Abstract: A refrigeration device may provide a snooze feature, in which the compressor of the refrigeration device is turned off for a predetermined period of time in response to a user command. The refrigeration device may also provide a quick chill feature, in which the compressor of the refrigeration device is turned on for a predetermined period of time in response to a user command. User commands for controlling the operation of the refrigeration device may be provide through a control panel, a remote control or a network interface.

Abstract: Disclosed is a burning/melting system for treatment infectious trash, which includes a trash feeding pipe to which the infectious trash is supplied; burners for burning the infectious trash supplied through the trash feeding pipe by using Brown's gas, when the amount of the infectious trash reaches a predetermined level; a melter for melting burned residues and glasses discharged from the burners thereto by using the Brown's gas; a post-combustion chamber for combusting toxic fumes produced from the burners and the melter by using the Brown's gas; a gas analyzing line for analyzing the toxic fumes having been combusted in the post-combustion chamber and if the amount of toxic elements contained in the combusted fumes exceeds a standard level, for feeding the combusted fumes back into the burners; and a gas outlet for discharging the combusted fumes to the outside if the amount of toxic elements contained therein is less than the standard level.
