Subscribe to The usa's largest dictionary and have countless numbers more definitions and Sophisticated lookup—ad free!
We’ve swapped superior present-day for top voltage, making the conductors much more productive at carrying power. What we’ve also carried out is make points a lot more unsafe. You could imagine voltage as electrical power’s desire to move. Superior voltages necessarily mean the power truly hopes to transfer and will even come across a means to circulation as a result of materials we Typically contemplate non-conductive, just like the air. The engineers planning substantial voltage transmission lines have to make sure that these lines are safe from arcing as well as other hazards that appear with significant voltage.
Crisis locator beacon – a portable battery powered radio transmitter used in emergencies to Identify airplanes, vessels, and people in distress and needing quick rescue. Various forms of emergency locator beacons are carried by plane, ships, motor vehicles, hikers and cross-nation skiers. From the event of an emergency, like the aircraft crashing, the ship sinking, or maybe a hiker starting to be lost, the transmitter is deployed and begins to transmit a ongoing radio signal, and that is utilized by lookup and rescue teams to speedily find the unexpected emergency and render assist.

Some power lines are marked with obstruction markers, Specially near air strips or over waterways that may assistance floatplane functions. The location of power lines at times use up sites that might normally be used by dangle gliders.[19][twenty]
Some media have an index of refraction which may differ slowly with situation and, as a result, light rays while in the medium are curved. This result is liable for mirages viewed on sizzling times: a transform in index of refraction air with height leads to light rays to bend, developing the looks of specular reflections in the distance (like within the floor of a pool of water).
b : involving the use of light-sensitive gadgets to obtain data to get a computer optical character recognition
We've examined above 140 speakers, and underneath are our recommendations with the best Bluetooth speakers for home. See our picks for the best smart speakers, the best spending plan and cheap Bluetooth speakers, plus the best Bluetooth speakers.
In certain courses, including radio and television broadcasting stations, the transmitter is specified a novel identifier consisting of the string of letters and quantities called a call indication, which should be used click to read in all transmissions.[forty six] So that you can regulate, manage, or internally repair radiotelephone transmitters, people should hold a federal government license, like the normal radiotelephone operator license while in the US, received by having a examination demonstrating satisfactory technological and authorized familiarity with Secure radio Procedure.[47]
HD Radio is an alternate electronic radio regular commonly carried out in North America.[sixty seven] An in-band on-channel technology, HD Radio broadcasts a electronic sign in a subcarrier of the station's analog FM or AM sign. Stations can multicast multiple audio signal in try this the subcarrier, supporting the transmission of various audio products and services at different bitrates.
What are the best surround sound speakers for your personal home? The solution mainly will depend on the size of the space. This tutorial walks you through how to construct a effectively-matched home theater system.
Wireless microphone – a battery-powered microphone with a short-assortment transmitter that's handheld or worn on anyone's overall body which transmits its sound by radio into a nearby receiver device connected to a sound system. Wireless microphones are employed by public speakers, performers, and tv personalities so they can go freely without trailing a shower speaker microphone wire. Usually, analog versions transmit in FM on unused parts of the television broadcast frequencies while in the VHF and UHF bands.
