A wall-mounted automatic hand sanitizer dispenser's mechanism is built in such a way that it can automatically distribute the antiseptic. The device's built-in infrared sensor detects the user's presence and releases the appropriate amount of sanitizer when it detects an object underneath.

A device that creates a wind barrier over an open entryway or entrance is an air curtain, often referred to as an air gate. An invisible wall that divides two locations, such as an indoor space and an outside environment, is created by blowing a laminar stream of air over a door or entrance. The air curtain reduces energy use and maintains indoor air quality by blocking the passage of outdoor air and preventing conditioned air from escaping from the enclosed space. In commercial and industrial settings like shops, eateries, hospitals, and factories, air curtains are frequently employed.
