The iPhone Stereo Headset was introduced in 2007 and was bundled with the original iPhone and iPhone 3G, and featured a control capsule in-line with the left earbud's wire with a microphone and a single button, actuated by squeezing the unit, which can be programmed to control calls, presentations, music and video playback, launch Siri, or take pictures with the Camera application.
Pair testing is a software development technique in which two team members work together at one keyboard to test the software application.One does the testing and the other analyzes or reviews the testing.
Pair programming is a software development technique in which two programmers work together at one workstation. One, the driver , writes code while the other, the observer or navigator , [ 1 ] reviews each line of code as it is typed in.
A bonded twisted pair is a construction variant in which the two wires of each pair are bonded together for the length of the cable. Pioneered by Belden, it is intended to help assure configuration consistency during and after installation.
The wire pairs are referenced directly by their color combination, or by the pair number. For example, pair 9 is also called the red-brown pair. In technical tabulations, the colors are often suitably abbreviated. Violet is the standard name in the telecommunications and electronics industry, but it is sometimes referred to as purple.
In the A-U Hoogsteen base pair, the adenine is rotated 180° about the glycosidic bond, resulting in an alternative hydrogen bonding scheme which has one hydrogen bond in common with the Watson-Crick base pair (adenine N6 and thymine N4), while the other hydrogen bond, instead of occurring between adenine N1 and thymine N3 as in the Watson ...
An unnatural base pair (UBP) is a designed subunit (or nucleobase) of DNA which is created in a laboratory and does not occur in nature. DNA sequences have been described which use newly created nucleobases to form a third base pair, in addition to the two base pairs found in nature, A-T (adenine – thymine) and G-C (guanine – cytosine).
Simplified graphical depiction of active noise reduction. To cancel the lower-frequency portions of the noise, noise-cancelling headphones use active noise control or ANC.A microphone captures the targeted ambient sounds, and a small amplifier generates sound waves that are exactly out of phase with the undesired sounds.
