    • A ventilator including a case having a supply air port to introduce outdoor air and an exhaust air port to discharge indoor air, a supply and exhaust air duct to communicate with the supply air port and the exhaust air port, and a partition disposed in the supply and exhaust air duct to divide the supply and exhaust air duct into a supply air region to communicate with the supply air port and an exhaust air region to communicate with the exhaust air port, the partition having protrusions protruding outward from opposite ends of the supply and exhaust air duct, the protrusions being bent. The partition is easily inserted into the supply and exhaust air duct by the bent protrusions of the partition to prevent leakage of indoor air and outdoor air and thus prevents the outdoor air and the indoor air from being mixed.

    • A method and an apparatus are provided for preventing the leakage of client information in banking automation equipment, such as an automated teller machine (ATM) or a cash dispenser (CD). More specifically, a method and an apparatus utilize infrared light-emitting elements that are generally attached on the periphery of the personal identification number (PIN) pad or a key pad. The infrared light is emitted at regular intervals when a user enters a password, thereby preventing a third party from capturing images of client password and financial transaction information using a camera. In addition, a peep-prevention shield can be installed on the periphery of the key (PIN) pad body to hide a motion of a user's hand, and more than one infrared light-emitting source can be mounted on an upper surface of the peep-prevention shield.
