Proposal for Automated Speed Radars for North Luzon Expressway I. INTRODUCTION 1.1 Purpose This document purposes an automated method teaching the speed violators at North Luzon Expressway. The automation system is necessary to easily detect those violators who are going beyond the speed limit and to improve the security in NLEX. 1.2 Background The North Luzon Expressway or NLEX runs a total distance of 84 kilometers from Balintawak‚ Quezon City to Sta. Ines‚ Pampanga.

Signal amplification circuit The ultrasonic signal which was received with the reception sensor is amplified by 1000 times(60dB) of voltage with the operational amplifier with two stages. It is 100 times at the first stage (40dB) and 10 times (20dB) at the next stage. As for the dB (decibel)‚ refer to "Logarithm Table". Generally‚ the positive and the negative power supply are used for the operational amplifier. The circuit this time works with the single power supply of +9 V. Therefore‚ for the

SYNOPSIS Subject :- ULTRASONIC RADAR Group Members :- INTRODUCTION Radar is a system that uses electromagnetic waves to identify the range‚ altitude‚ direction‚ or speed of both moving and fixed objects such as aircraft‚ ships‚ motor vehicles‚ weather formations and terrain. The term RADAR was coined in 1941 as an acronym for Radio Detection and Ranging. The term has since entered the English language as a standard word‚ radar‚ losing the capitalization in the process. Radar was originally called

addresses the concept of Adaptive Cruise Control and its improved versions. ADAPTIVE CRUISE CONTROL (ACC) PRINCIPLE OF ACC ACC works by detecting the distance and speed of the vehicles ahead by using either a Lidar system or a Radar system. The time taken by the transmission and reception is the key of the distance measurement while the shift in frequency of the reflected beam by Doppler Effect is measured to know the speed. According to this‚ the brake and throttle controls are

ultrasonic motor INTRODUCTION All of us know that motor is a machine which produces or imparts motion‚ or in detail it is an arrangement of coils and magnets that converts electric energy into mechanical energy and ultrasonic motors are the next generation motors. In 1980‚the world’s first ultrasonic motor was invented which utilizes the piezoelectric effect in the ultrasonic frequency range to provide its motive force resulting in a motor with unusually good low speed‚ high torque

MICROCONTROLLER BASED ULTRASONIC DISTANCE MEASUREMENT ABSTRACT: The microcontroller based ultrasonic distance measuring device is a device used to calculate the distance between the ultrasonic transmitter/receiver and the object whose distance is to be measured. A microcontroller is used to calculate the delay time between the transmitted signal and the received signal. ULTRASONIC WAVES: Ultra means “beyond” and sonic means “sound”. Ultrasonic refers to sound waves

History of ARPA (Automatic Radar Plotting Aids) The availability of low cost microprocessors and the development of advanced computer technology during the 1970s and 1980s have made it possible to apply computer techniques to improve commercial marine radar systems. Radar manufactures used this technology to create the Automatic Radar Plotting Aids (ARPA). ARPAs are computer assisted radar data processing systems which generate predictive vectors and other ship movement information. The International
