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.
