Abstract (en)
The pulses are transmitted by means of a spring (L) which is susceptible to store energy through elastic deformation between two pulses and transmitting this to a regulator on each pulse. A leaf spring (L) is compressed to elastically deform to a first position corresponding to a first fundamental buckling mode. During a half period oscillation of regulator (R), energy in the spring (L) is stored by using a fraction of the energy from the source (S) to elastically deform the spring (L) into a second position close to an unstable position corresponding to a greater buckling mode. Again the spring is deformed to an unstable position using a fraction of the kinetic energy from the oscillating regulator (R), so that spring deforms to a third stable position corresponding to a fundamental mode which is the inverse of the first position. The energy liberated in this transformation is transmitted to the oscillating regulator (R). This sequence is repeated during the inverse half period of the regulator (R) so as to complete the period of oscillation.
