摘要： The present invention relates to an improved gyro-type manually operated dynamo mechanism applied to appliances consuming limited momentary power. Energy is stored by stressing a spring which, when released, keeps in mechanical connection with a train of acceleration gears terminating in a relatively heavy flywheel when the stressed spring is released to resume its unstressed state, and disconnects therewith when the spring reaches unstressed condition and allow the flywheel to rotate freely, thereby enhancing the exploitation of the energy stored in the flywheel in the form of inertia to produce the requisite electricity to sound the buzzer.

摘要： An energy harvester includes an elongated tubular casing extending around a longitudinal axis between opposed first and second ends. A body is arranged in the casing. A helical electrical winding is wound around the longitudinal axis. The body is arranged to move along the longitudinal axis with alternate motion away from the first end towards the second end and away from the second end towards the first end. As a result of this alternate motion, an electromotive force is produced in the at least one helical electrical winding. Furthermore, at least one of the first and second ends includes a piezoelectric transducer that is configured to co-operate in a kinetic energy transfer relationship with the at least one body to generate an electric voltage as a result of the at least one body reaching, in the alternate motion, an end-of-travel position towards the piezoelectric transducer.
