The disclosure is directed to an apparatus or a system for generating energy in response to a vehicle wheel rotation. The apparatus or the system may include a roller configured to be positioned in substantial physical contact within a groove of a wheel of the vehicle. The roller may be configured to rotate in response to a rotation of the wheel. The apparatus or the system may further include a flexible arm rotatably couplable to the roller such that rotation of the roller causes the flexible arm to rotate. The flexible arm may be configured to exert a downward force on the roller to increase the friction between the roller and the groove of the wheel. The apparatus or the system may further include a first generator operably coupled to the flexible arm and configured to generate an electrical output based on the rotation of the flexible arm shaft and convey the electrical output to an energy storage device or vehicle motor.

A system and method to harvest vibration-based energy for generation of electrical power employs a magnet that travels vertically within an axial chamber between a set of upper and lower coils of magnet wire. The magnet is supported by a spring structure specifically selected to allow the magnet to travel freely and equally vertically relative to the coils allowing the capture of energy for the generation of electrical power on both the original movement of the magnet relative to the coil and on the return movement resulting from spring load on the magnet.

A method for capturing energy from an oscillating object, in which at least one unbalanced rotor is oscillated to rotate the rotor(s) while reciprocally pivoting each of the rotor(s) about a respective counter-oscillation axis that is substantially perpendicular to both a rotation axis of the rotor and the oscillation axis for the oscillating object. Reciprocally pivoting the rotor(s) about the respective counter-oscillation axis urges the rotor to rotate continuously instead of reciprocally, and energy from rotation of the rotor can be captured, for example mechanically or electrically. Optionally, the counter-oscillation axis may be moved to maintain the counter-oscillation axis perpendicular to the oscillation axis for the oscillating object.

The disclosure is directed to methods and systems for provisioning mobile electric vehicles with various operational settings data transmitted over the air. A vehicle or its components may operate according to operational settings corresponding to operational settings data included in the vehicle components. A server that is remote to the vehicle may comprise operational settings data and may transmit operational settings data to the vehicle. The server may transmit operational settings data automatically, such as on a periodic basis, in response to a request, such as from a user or from a vehicle component or anytime new or updated operational settings data are available for the vehicle or its components.
