      Ultrasonic Humidifier

      An ultrasonic humidifier is a device that uses ultrasonic sound waves to create water droplets from a built-in water reservoir. Ultrasonic humidifiers are used in many homes, businesses, and warehouses to properly humidify an area without using heat. Because ultrasonic humidifiers do not use heat, they use much less electricity (approximately 93% less) than other

    • What is a Rotameter?

      What is a Rotameter?

      A rotameter is a device that measures the flow rate of a liquid or gas in a tube. Karl Kueppers invented the rotameter in 1908, which has been widely used since then for a variety of applications. Rotameters are included in a class of devices known as “variable area meters” that depend on the substance

    • Nanotubes

      Nanotubes

      A nanotube is a cylinder made up of atomic particles and whose diameter is around one to a few billionths of a meter (or nanometers). They can be made from a variety of materials. Nanotubes are believed to be stronger than steel, but more flexible than plastic, and they also exhibit excellent thermal and electrical conductivity. These

    • How Traffic Cameras Work

      How Traffic Cameras Work

      There are several different types of traffic cameras. Some types of traffic cameras are only focused on traffic patterns and traffic density. Other types of traffic cameras are placed in locations where traffic infractions commonly occur to capture traffic incidents and record the details for punitive purposes. Cameras for Traffic Monitoring Cameras for traffic monitoring

    • Backscatter X-Ray

      Backscatter X-Ray

      Backscatter X-ray machines were built specifically for airport security. Backscatter X-ray technology can strip off a person’s clothing in the captured image to show him or her practically naked. In the process, it will show any contraband such as ceramic knives, liquid explosives or drugs that the person was carrying but were previously undetectable by

    • What is an Ultrasonic Pest Repeller?

      What is an Ultrasonic Pest Repeller?

      An Ultrasonic Pest Repeller is an electronic device that uses ultrasonic sound waves to repel insects, rodents, and other pests. Though humans are incapable of hearing these sounds, many animals, insects, and rodents can. There is much debate concerning the ultrasonic pest repeller’s ability to actually get rid of pests. While some people claim that

    • Intelligent Transportation Systems

      Intelligent Transportation Systems

      Intelligent transportation systems are projects that aim to integrate modern communication and information technology into existing transportation management systems in order to optimize vehicle life, fuel efficiency, safety, and traffic in urbanized cities. The need for intelligent transportation systems stems from the fact that traffic congestion has been increasing all around the world because of

    • Methyl Iodide

      Methyl Iodide

      Methyl Iodide is a chemical compound that is relatively volatile. It is commonly found in the form of a dense, colorless liquid. It is also known as iodomethane and has the chemical formula CH3I (one carbon atom with three hydrogen atoms and a single iodine atom connected to it). Methyl iodide is a naturally occurring

    • What is a Goniometer?

      What is a Goniometer?

      A goniometer is a device that either measures an angle or moves an object along a fixed point to a specific angular position. Goniometers have many uses and can be found in a number of industries. They measure range of motion, determine direction, and measure an object’s dimensions. Goniometers are relatively simple in design and

    • Vehicle Platooning

      Vehicle Platooning

      Vehicle platooning is one of the innovations in the automotive industry that aim to improve the safety, efficiency, mileage, and time of travel of vehicles while relieving traffic congestion, decreasing pollution and reducing stress for passengers. One of the recent demonstrations of this technology was during the PATH program done in California by 8 Buicks
