Lorenz beam — The Lorenz beam blind landing system was an air radio navigation system in use from the late 1930s. The name refers to the company that produced the system; Lorenz referred to it simply as the Ultrakurzwellen Landefunkfeuer, German for ultra… … Wikipedia
Radio-frequency identification — (RFID) is a technology that uses radio waves to transfer data from an electronic tag, called RFID tag or label, attached to an object, through a reader for the purpose of identifying and tracking the object. Some RFID tags can be read from… … Wikipedia
RFQ Beam Coolers — RFQ stands for Radio Frequency Quadrupole (also known as a Quadrupole mass analyzer when used as a mass filter), an instrument that is used in mass spectrometry. The RFQ was invented by Prof. Wolfgang Paul in the late 50 s / early 60 s at the… … Wikipedia
Very low frequency — or VLF refers to radio frequencies (RF) in the range of 3 kHz to 30 kHz. Since there is not much bandwidth in this band of the radio spectrum, only the very simplest signals are used, such as for radio navigation. Also known as the myriameter… … Wikipedia
