Abstract: A compound bow may feature the ability to pre-store energy before the drawing back of the draw string. Various embodiments contemplate that this may allow an archer to draw back the draw string or cable, and upon reaching the let off region of the compound bow's draw profile, cause the pre-stored energy to be transferred to the energy being stored by the bow. Various embodiments contemplate that this addition of pre-stored energy may give the archer more energy, held in the draw string or cable, to transfer to an arrow upon release, propelling it at greater speeds than would have been achieved with a compound bow of equal draw weight that does not feature an energy storage mechanism. Various embodiments contemplate that a system may provide for a return position of the draw. For example, this may remove the pre-stored energy from the draw string or cable as the draw string or cable is returned to an undrawn position.
