Abstract:
1. A rebound-effector for inducing periodic, back and forth oscillated, without external reaction, forces and/or moments, comprising: a weight accelerated back and forth, wherein in one period time there are four phases of operation, as follows: a driving source for accelerating the weight to the “left”, and a driving source for accelerating the weight to the “right”, wherein, during one period time, at least one driving source is disconnected from, or does not apply on, or does not accelerate the weight for two phases, and wherein, during one period time, each of the driving sources is constantly connected to, or applies on, or accelerates the weight, for at least two phases; and a system to take care of introducing, and disconnecting, of at least one driving source to and from the weight; the rebound-effector being adapted to further store and reuse energy as follows:
