Energy Harvesting Systems and Methods for Vehicles
First Claim
1. An energy-supply module for supplying energy to operate a component derived from movement of the vehicle, comprising:
- an energy-storage and supply device arranged to supply energy to the component;
at least one movable mass;
at least one mechanical-electrical converter coupled to said at least one mass to convert the movement of the mass into electric signals; and
a rectifier coupled to each converter, said energy-supply and storage device being coupled to said rectifier to enable charging of said energy-storage and supply device during movement of said at least one mass.

Abstract
Vehicular on-board energy generating system includes a coil and a magnet movable in a passage of the coil during movement of the vehicle such that the movement of the magnet relative to the coil causes generation of electricity. The coil may be wrapped around a cylinder, and its passage may include a chamber defined by the cylinder. An energy storage device is coupled to the coil and arranged to receive and store the generated electricity. One or more sensors can additionally or alternatively be coupled to the coil and arranged to receive and use the generated electricity. A control module can also be coupled to the sensor and arranged to control a component in the vehicle based at least in part on data provided by the sensor.

21. A vehicle including an on-board energy generating system, comprising:
-
a housing;
a cantilever member attached to said housing in a position in which it vibrates during movement of the vehicle;
a piezoelectric crystal arranged between said cantilever member and a portion of said housing and arranged to be compressed by said cantilever member during its vibration and generate electricity upon compression; and
a wire connecting said piezoelectric crystal to an electricity-consuming device for supplying electricity to the electricity-consuming device.
