Abstract: The present invention relates to an electric vehicle charging system comprised of at least one duct, at least one fan, at least one fan pulley wheel and fan pulley wheel band, and at least one alternator with at least one alternator pulley wheel. The duct is positioned behind a grill of an electric vehicle such that air is funneled through the duct and into the fan, causing the fan to spin which turns an alternator through a series of pulleys such that the alternator charges the battery of the electric vehicle.

Abstract: A fibre optic sensor deployed on a fibre optic cable to a remote location, such as an oil or gas well. The sensor, which can sense any of a variety of parameters such as pressure, temperature, flow rate, strain, or chemical properties, is located within a sleeve. The sleeve is constructed from a low-friction material, such as polytetrafluoroethylene, glass, or ceramic. Further, the sensor can float on a high-density fluid that surrounds it, or sink in a low-density fluid that surrounds it.
