The CMS detector is built around a huge solenoid magnet. This takes the form of a cylindrical coil of superconducting cable that generates a magnetic field of 4 tesla, about 100 000 times that of the Earth. The magnetic field is confined by a steel 'yoke' that forms the bulk of the detector's weight at 12,500 t.
U.S. Army soldiers use a military standard metal detector. A metal detector is an instrument that detects the nearby presence of metal. Metal detectors are useful for finding metal objects on the surface, underground, and under water. A metal detector consists of a control box, an adjustable shaft [dubious – discuss], and a variable-shaped ...
The Foster–Seeley discriminator [1] [2] is a common type of FM detector circuit, invented in 1936 by Dudley E. Foster [3] and Stuart William Seeley. The Foster–Seeley discriminator was envisioned for automatic frequency control of receivers , but also found application in demodulating an FM signal.
Many such devices contain non-functional circuitry or naively constructed approximations of radio transmitters. A few do have functional circuitry, putting out a weak signal with a function generator or a simple timer circuit, but are still largely useless in comparison with a coil-based metal detector; others have been found to contain intentionally obfuscated or completely superfluous ...
A metal rectifier is an early type of semiconductor rectifier in which the semiconductor is copper oxide, germanium or selenium. They were used in power applications to convert alternating current to direct current in devices such as radios and battery chargers .
Ferrous metals, such as iron and steel, allow for a longer sensing range, while nonferrous metals, such as aluminum and copper, may reduce the sensing range by up to 60 percent. [ 2 ] Since the output of an inductive sensor has two possible states, an inductive sensor is sometimes referred to as an inductive proximity switch .
Basketball Hall of Famers Vince Carter and Tracy McGrady are among 10 limited partners who have joined the Buffalo Bills’ ownership group. The noncontrolling, minority interests were approved ...
RFID on metal (abbreviated to ROM) are radio-frequency identification (RFID) tags which perform a specific function when attached to metal objects. The ROM tags overcome some of the problems traditional RFID tags suffer when near metal, such as detuning and reflecting of the RFID signal, which can cause poor tag read range, phantom reads, or no read signal at all.
