Abstract: Protective barrier includes a soft metal that inhibits or delays thermal or grinding attack tool penetration. The soft metal, which may be disposed between other layers and otherwise delays thermal attack by expanding or “puffing” during attack. The soft metal can inhibit mechanical attack by rapid ablation and wear of a cutting wheel or blade. The protective barrier may additionally include an oxide or carbide layer.

Abstract: A system to enable mobile marketing communication that includes a vehicular window coupled to a vehicle, an electronic display positioned adjacent to the vehicular window, and an information store that includes adverts. A vehicular state sensor is positioned proximate to the vehicular window and configured to detect driving events associated with the vehicle. A control circuit is communicatively coupled to the electronic display, the information store, and the vehicular state sensor. The control circuit is configured to determine, via the vehicular state sensor, the driving events. The control circuit is further configured to convey, via the electronic display, an advert when the driving event is a left turn, a right turn, a reversing state, or a parked state. The vehicular state sensor include lateral and longitudinal accelerometers that detect the lateral and longitudinal acceleration of the vehicle.
