  • Vehicle detection inductive loop activation device
    Patent number: 8212690
    Abstract: A passive activator, used in combination with a vehicle sensing arrangement in a roadway, includes an electrically conductive material such as a wire mesh and placed inside or within a vehicle tire. The electrically conductive material portion forms a closed loop. The electrically conductive material portion may also include a protective layer or liner to prevent damage to the tire or to an inner tube of the tire. The passive activator causes sufficient disturbance of the electro-magnetic field to activate a vehicle detection sensor located in a roadway when a tire equipped with the passive activator passes over the roadway induction loop.
