Construction of electronic cigarettes. An electronic cigarette is a handheld battery -powered vaporizer that simulates smoking, but without tobacco combustion. [ 1] E-cigarette components include a mouthpiece (drip tip [ 2] ), a cartridge (liquid storage area), a heating element / atomizer, a microprocessor, a battery, and some of them have an ...
The clearomizer allows the user to monitor the liquid level in the device. [256] Soon after the clearomizer reached the market, replaceable atomizer coils and variable voltage batteries were introduced. [256] Clearomizers and eGo batteries became the best-selling customizable e-cigarette components in early 2012. [255]
Rogowski coil. A Rogowski coil is a toroid of wire used to measure an alternating current I(t) through a cable encircled by the toroid. The picture shows a Rogowski coil encircling a current-carrying cable. The output of the coil, v(t), is connected to a lossy integrator circuit to obtain a voltage Vout(t) that is proportional to I(t).
Resonant inductive coupling or magnetic phase synchronous coupling[ 4][ 5] is a phenomenon with inductive coupling in which the coupling becomes stronger when the "secondary" (load-bearing) side of the loosely coupled coil resonates. [ 5] A resonant transformer of this type is often used in analog circuitry as a bandpass filter.
Bifilar coil. A bifilar coil is an electromagnetic coil that contains two closely spaced, parallel windings. In electrical engineering, the word bifilar describes wire which is made of two filaments or strands. It is commonly used to denote special types of winding wire for transformers. Wire can be purchased in bifilar form, usually as ...
An ignition coil is used in the ignition system of a spark-ignition engine to transform the battery voltage to the much higher voltages required to operate the spark plug (s). The spark plugs then use this burst of high-voltage electricity to ignite the air-fuel mixture . The ignition coil is constructed of two sets of coils wound around an ...
A chemical oxygen iodine laser ( COIL) is a near– infrared chemical laser. As the beam is infrared, it cannot be seen with the naked eye. It is capable of output power scaling up to megawatts in continuous mode. [citation needed] Its output wavelength is 1315 nm, a transition wavelength of atomic iodine . A COIL system mounted on a Boeing 747 ...
A coiled coil is a structural motif in proteins in which 2–7 [ 1] alpha-helices are coiled together like the strands of a rope. ( Dimers and trimers are the most common types.) They have been found in roughly 5-10% of proteins and have a variety of functions. [ 2] They are one of the most widespread motifs found in protein-protein interactions.
