Pretty nifty faucet from the folks at Kohler:
The Sensate touchless faucet frees your hands so you can speed through prep, cooking and cleanup without spreading messes and germs throughout the kitchen. Response™ technology makes Sensate respond to your every move. Simply wave your hand–or an object such as a pan or kitchen utensil—to turn Sensate on or off. Its state-of-the-art sensor is in tune with your every move, precision-designed to provide reliable operation every time. So there’s no need to worry about false activations when you’re working in the sink area.
