Abstract
A lid opening and closing system for a waste container having an opening and a lid for covering the opening, the system including a proximity sensor, which may be a capacitive proximity sensor, for sensing the presence of a user's hand or body near the waste container and for sending a control signal. A drive system is connected to the lid for causing the lid to move from a closed position, where the lid covers the opening, to an open position, where the waste container is positioned to accept waste, and then back to the closed position in response to the control signal. The proximity sensor being more sensitive to the user's hand or body approaching from the top of the waste container rather than from the front, sides or back of the waste container.
