KINETIC ENERGY HARVESTING METHODS AND APPARATUS
First Claim
1. A kinetic energy harvesting apparatus comprising:
- a magnet housing configured to have a tubular shape;
a first end-cap magnet configured to connect to a first end of the magnet housing such that a north-pole of the first end-cap magnet faces the first end;
a second end-cap magnet configured to connect to a second end of the magnet housing such that a south-pole of the second end-cap magnet faces the second end;
a first wire coil configured to be connected to the magnet housing between the first end and a center of the magnet housing;
a second wire coil configured to be connected to the magnet housing between the second end and the center of the magnet housing; and
a central magnet configured to be located within the magnet housing between the first end and the second end such that a north-pole of the central magnet faces the north-pole of the first end-cap and a south-pole of the central magnet faces the south-pole of the second end-cap causing the central magnet to be suspended between the first and second end-caps of the magnet housing.

Abstract
A system, method, and apparatus for kinetic energy harvesting are disclosed. An example kinetic energy harvesting apparatus includes a tubular-shaped magnet housing, a first end-cap magnet configured to connect to a first end of the magnet housing and a second end-cap magnet configured to connect to a second end of the magnet housing. The apparatus also includes a first wire coil configured to be connected to the magnet housing between the first end and a center of the magnet housing and a second wire coil configured to be connected to the magnet housing between the second end and the center of the magnet housing. The apparatus further includes a central magnet configured to be located within the magnet housing between the first end and the second end such that the central magnet is suspended within the magnet housing.
