  • Publication number: 20210339635
    Abstract: A traffic regulation system and method which combines energy harvesting from the movement of a plurality of vehicles on a roadway with wireless directional power beam transmission using the harvested energy to encourage compliance with traffic regulations. Electric power is generated from the movement of the moving vehicles by using a wind turbine to harvest wind energy from the movement of vehicles or by piezoelectric plates which harvest compression energy from the weight of the vehicle tires on the road surface. The electric power is transmitted to electric or hybrid vehicles which comply with the traffic regulations. The traffic regulations are one of driving at a posted speed and driving at a safe following distance. A control system adjusts the traffic regulation based on measurements received from a plurality of detectors.

  • Patent number: 11162918
    Abstract: A method for determining a quality of a friction stir welded seam is described. The method involves applying an impact to a welded plate and comparing its damping capacity with the damping capacity of a geometrically equivalent defect-free plate. Damping capacities that differ by a small percent difference indicate that the welded plate is also defect-free. This method is particularly advantageous when dealing with small defects, which produce miniscule changes in natural frequency which may not be measureable.
