摘要

The device for Measuring the speed of vehicles on a Road, especially applicable to police control of Speed mu00e1ximay / or minimumElectro-optical cross links comprises two parallel to each other, separated a Predetermined distance.Capable of being interrupted by vehicles; recipients of such links connected to a Processor Circuit that provides an indicator of the speed MeasurementAble to detect the difference between the start time of interruptions and determine the Vehicle Speed by dividing a representative amount of the citadadistancia defaultFor a particular amount of such Representative Measurement of the difference between Times.The device in this Invention Overcomes effectively the already known to be staticEasy to install and requires no Operator much more than simply Reading; it is simpler and more economic than any of the known
