Abstract
A scale may include a conveyor belt that carries a load, where the load has a weight. A generator is included that receives mechanical energy arising from movement of the conveyor belt and outputs electrical energy that corresponds to a rate of movement of the conveyor belt. At least one load cell receives the electrical energy from the generator, senses the weight of the load, and outputs a voltage that corresponds to the weight of the load and the rate of movement of the conveyor belt.
