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.

Abstract: An apparatus for transporting cargo includes a longitudinal rotatable support arm and at least one bracing arm that extending in a substantially perpendicular direction from the longitudinal arm. No more than one of the bracing arms contacts and supports a corner of the cargo. At least one of the bracing arms preferably includes an extendable assembly for providing at least partial support of the cargo. The extendable assembly may include, for example, a sleeve and a movable structure located within the sleeve, wherein the movable structure may be extended from the sleeve to contact the cargo.
