microphone

A device that converts sound waves into analogous electrical waves. Commonly called a "mic" (pronounced "mike"), it contains a flexible diaphragm composed of film or foil that vibrates as it makes contact with the sound. The diaphragm movement modulates an electrical current by various methods. In a carbon mic, used in telephones for more than a hundred years, the diaphragm alters the pressure in carbon grains, changing its resistance.

Condenser Microphones
In a condenser mic, also called an "electrostatic mic" or "capacitor mic," the diaphragm changes the capacitance between itself and a metal plate, both acting as electrodes. The widely used electret mic has a charged dielectric between the electrodes that generates voltage.

Crystal and Dynamic Microphones
Crystal microphones use a piezoelectric diaphragm that produces voltage when subjected to the sound waves (mechanical pressure).

Dynamic mics, which are like speakers in reverse, use a diaphragm attached to a movable coil that generates voltage as air moves the coil between the poles of a magnet.

Directionality
Unidirectional shotgun and cardioid mics aimed at a sound source eliminate much of the ambient noise, whereas omnidirectional microphones capture everything in the surrounding environment. The cardioid name comes from its heart-shaped pickup pattern. In the past, bidirectional mics were used for interviews; however, two unidirectional mics are commonly used instead. See cardioid mic.

Xeon Phi

A family of x86 coprocessors from Intel for parallel computing. Dubbed the "Many Integrated Core" (MIC) architecture, Xeon Phi chips run at lower speeds than ordinary Intel CPUs but make up for the speed with multiple cores. Xeon Phi chips can be used stand-alone or in conjunction with Intel's full-blown Xeon processors. The 50-core Knights Corner was the first implementation of the Xeon Phi line, followed by Knights Landing. See Xeon and high-performance computing.

"Well, Mas'r Jaggers," returned Mike, in the voice of a sufferer from a constitutional cold; "arter a deal o' trouble, I've found one, sir, as might do."

"Well, Mas'r Jaggers," said Mike, wiping his nose on his fur cap this time; "in a general way, anythink."

Mike looked hard at my guardian, as if he were trying to learn a lesson from his face, and slowly replied, "Ayther to character, or to having been in his company and never left him all the night in question."

Mike looked at his cap, and looked at the floor, and looked at the ceiling, and looked at the clerk, and even looked at me, before beginning to reply in a nervous manner, "We've dressed him up like--" when my guardian blustered out:

After some helpless casting about, Mike brightened and began again:

"I left him," said Mike, "a settin on some doorsteps round the corner."

In memoriam: Michael J. Dueker

But it was at Scent-Lok where Mike's passion and artistic bent served him best as he helped guide the company through very challenging times.

Thank you, Mike: This industry stalwart knew his way around both bowstrings and guitar strings..
