CHAPTER I THE PROJECT AND ITS SETTINGS Introduction The use of audible traffic lights at pedestrian crossing is to assist the vision less and disabled persons across any intersections. When reaching a pedestrian crossing‚ and knowing which direction to cross‚ the visionless and disabled persons must then know when to begin their crossing after hearing the audible traffic light’s signal sound. Since the traffic lights and the audible device are wired in parallel‚ as soon as the traffic

Rotating a DC electric motor’s rotor will produce electricity and voice-coil speakers can also act as microphones. ------------------------------------------------- Applications Electromagnetic: * Antenna – converts propagating electromagnetic waves to and from conducted electrical signals * Magnetic cartridge –

circuit looks something like this: Typically in industrial relay logic circuits‚ but not always‚ the operating voltage for the switch contacts and relay coils will be 120 volts AC. Lower voltage AC and even DC systems are sometimes built and documented according to "ladder" diagrams: So long as the switch contacts and relay coils are all adequately rated‚ it really doesn’t matter what level of voltage is chosen for the system to operate with. Note the number "1" on the wire between

industry. More specifically the company buys “master coils” of steel from producers (master coils are generally 48/72 inches wide and weigh as much as 60‚000 pounds) in bulk quantities. These coils are then “processed” before being shipped to the company’s customers for use as a vital raw material. Processing mainly involves activities such as “cutting to length” (providing sheets of a certain size rather than coils)‚ “precision shifting” (providing coils of a narrower width) and “tension leveling” (providing

War of Currents Two of the greatest inventors in American history are Thomas Edison and Nikolas Tesla. However‚ they had not achieved their success on their own. Many argue that the rivalry between them had pushed them to create technology which we still use today. Without the extraordinary relationship between the two‚ Tesla and Edison would not have accomplished the level of success both of them had. In the beginning‚ the men had great respect for each other. Tesla had left Serbia for New
