Abstract: The secure license plate holder is specific to the vehicle to which it is assigned, having the vehicle identification number (VIN) permanently disposed on the holder. The holder is secured with tamperproof security fasteners requiring specialized tools for installation and removal. The license plate is also secured to the holder with tamperproof security fasteners. Decorative covers are installed over the fastener heads to prevent misinterpretation of the head as a part of the alphanumeric characters on the license plate and to indicate tampering. The holder includes an embedded SIM (subscriber identity module) chip, and the vehicle has a corresponding chip installed therein. Thus, removal of the plate and holder requires removal of part of the vehicle structure in order to avoid obvious damage to the fasteners and their covers.

Abstract: The system for remote control of retractable, ground-based vehicle barriers increases control of the emergency lane of the road by mounting ground signboards in the emergency lane to prevent any vehicle to pass through this lane and so the police vehicle or the ambulance can easily and quickly approach the site of accident through the emergency lane. The signboards include a U-shaped frame permanently mounted in the emergency lane and a panel pivotally attached to the frame. Servo motors are provided to rotate the panels between a vertical position providing a barrier to traffic and a horizontal position permitting an emergency response vehicle to travel through the emergency lane. The emergency response vehicle is provided with a remote control unit having a short-range transmitter that transmits a trigger signal that is received by a unit at the barrier sign to activate a motor controller to lower the sign.
