Abstract: A laser transponder and method for disabling a laser-based speed monitor of the type that transmits a monitor laser beam at a moving motor vehicle. The monitor laser beam transmitted by the speed monitor is detected when it arrives at the motor vehicle. In response to detecting the monitor laser beam, a warning is output to the motor vehicle driver and a jamming laser beam is transmitted toward the speed monitor. The jamming laser beam includes a plurality of pulses separated from each other by a time period that is less than or equal to an amount of time needed for the monitor laser beam to travel from the speed monitor to the motor vehicle and back to the speed monitor. The jamming laser beam disables the speed monitor for a time period sufficient to allow the motor vehicle driver to reduce the speed of the motor vehicle.

Abstract: A laser transponder for disabling a laser-based speed monitor of the type that transmits a monitor laser beam at a moving motor vehicle. In response to detecting the monitor laser beam, a warning is output to the motor vehicle driver and a jamming laser beam is transmitted toward the speed monitor. The jamming laser beam disables the speed monitor for a time period sufficient to allow the motor vehicle driver to reduce the speed of the motor vehicle. The laser transponder includes a housing that acts as both a heat sink for the laser transmitter in the laser transponder and a structural package that is waterproof and sufficiently rugged to be positioned on the outside of the motor vehicle. The laser transponder is securely attached to the motor vehicle by a connection system that enables a user to adjust the angular orientation of the laser transponder as necessary to detect the monitor laser beam and transmit the jamming laser beam to the speed monitor.
