Xerox was founded in 1906 in Rochester as The Haloid Photographic Company,[8] which originally manufactured photographic paper and equipment. The company subsequently changed its name to Haloid Xerox in 1958 and then simply Xerox in 1961.[9] Xerography, a modern word meaning "dry writing" developed from two Greek roots, is the name of the process invented in 1938 and developed by the Haloid Company. The company came to prominence in 1959 with the introduction of the Xerox 914,[10] the first plain paper photocopier using the process of Electro-photography, (later changed to xerography) discovered by Chester Carlson, which he developed with John H. Dessauer.

Weber (unit) From Wikipedia, the free encyclopedia Jump to: navigation, search In physics, the weber (symbol: Wb;  /ˈveɪbər/, /ˈwɛbər/, or /ˈwiːbər/) is the SI unit of magnetic flux. A flux density of one Wb/m2 (one weber per square meter) is one tesla. The weber is named for the German physicist Wilhelm Eduard Weber (1804–1891). [edit] Definition

The weber may be defined in terms of Faraday's law, which relates a changing magnetic flux through a loop to the electric field around the loop. A change in flux of one weber per second will induce an electromotive force of one volt (produce an electric potential difference of one volt across two open-circuited terminals). Officially,

Weber (unit of magnetic flux) — The weber is the magnetic flux which, linking a circuit of one turn, would produce in it an electromotive force of 1 volt if it were reduced to zero at a uniform rate in 1 second.[1]

In SI base units, the dimensions of the weber are (kg·m2)/(s2·A). The weber is commonly expressed in terms of other derived units as the Tesla-square meter (T·m2), volt-seconds (V·s), or joules per ampere (J/A). 1 Wb = 1 V·s = 1 T·m2 = 1 J/A = 108 Mx (maxwells).

USS Lincoln VS canada This is the translation of the ACTUAL radio conversation of a U.S. naval ship with the Canadian authorities off the coast of Newfoundland. The Chief of Naval Operations on October 10th 1995 released the radio conversation. Canadians: Please divert your course 15 degrees to the South to avoid a collision. Americans: Recommend you divert your course 15 degrees to the North. Canadians: Negative. You will have to divert your course 15 degrees to the South to avoid a collision. Americans: This is the Captain of a US Navy ship. I say again, divert YOUR course. Canadians: No. I say again, you divert YOUR course. Americans: THIS IS THE AIRCRAFT CARRIER USS LINCOLN. THE SECOND LARGEST SHIP IN THE UNITED STATES ATLANTIC FLEET. THREE DESTROYERS, THREE CRUISERS AND NUMEROUS SUPPORT VESSELS ACCOMPANY US. I DEMAND THAT YOU CHANGE YOUR COURSE 15 DEGREES NORTH, I SAY AGAIN, THAT'S ONE FIVE DEGREES NORTH, OR COUNTERMEASURES WILL BE UNDERTAKEN TO ENSURE THE SAFETY OF THIS SHIP. Canadians: We are a lighthouse. Your call.

Researchers create super-small transistor, artificial atom powered by single electrons
...

The SketchSET—which is the first single-electron transistor made entirely of oxide-based materials—consists of an island formation that can house up to two electrons. The number of electrons on the island—which can be only zero, one, or two—results in distinct conductive properties. Wires extending from the transistor carry additional electrons across the island.

One virtue of a single-electron transistor is its extreme sensitivity to an electric charge, Levy explained. Another property of these oxide materials is ferroelectricity, which allows the transistor to act as a solid-state memory. The ferroelectric state can, in the absence of external power, control the number of electrons on the island, which in turn can be used to represent the 1 or 0 state of a memory element. A computer memory based on this property would be able to retain information even when the processor itself is powered down, Levy said. The ferroelectric state also is expected to be sensitive to small pressure changes at nanometer scales, making this device potentially useful as a nanoscale charge and force sensor.
