Abstract
A sensing system, used to sense the presence of an object in an apparatus operating in different modes, has a light-emitting element and a light-sensing element. The light-emitting element is driven continuously in one of the operating modes, for quick sensing of the object, and is pulsed in another of the operating modes, to reduce power dissipation by the sensor system.
