4B5B

In telecommunication, 4B5B is a form of data communications Block Coding. 4B5B maps groups of four bits onto groups of 5 bits, with a minimum density of 1 bits in the output. When NRZI-encoded, the 1 bits provide necessary clock transitions for the receiver. For example, a run of 4 bits such as 0000 contains no transitions and that causes clocking problems for the receiver. 4B/5B solves this problem by assigning each block of 4 consecutive bits an equivalent word of 5 bits. These 5 bit words are pre-determined in a dictionary and they are chosen to ensure that there will be at least two transitions per block of bits.

A collateral effect of the code is that more bits are needed to send the same information than with 4 bits. An alternate to using 4B5B coding is to use a scrambler. Depending on the standard or specification of interest, there may be several 4b5b characters left unused. The presence of any of the "unused" characters in the data stream can be used as an indication that there is a fault somewhere in the link. Therefore, the unused characters can actually be used to detect errors in the data stream.

History

Beginnings and national expansion

In 1852, German American brewer and saloon operator George Schneider opened the Bavarian Brewery on Carondelet Avenue (later known as South Broadway) between Dorcas and Lynch streets in South St. Louis. Schneider's brewery expanded in 1856 to a new brewhouse near Eighth and Crittenden streets; however, the following year financial problems forced the sale of the brewery to various owners during the late 1850s. In 1860, the brewery was purchased on the brink of bankruptcy by William D'Oench, a local pharmacist, and Eberhard Anheuser, a prosperous German-born soap manufacturer. D'Oench was the silent partner in the business until 1869, when he sold his half-interest in the company. From 1860 to 1875, the brewery was known as E. Anheuser & Co., and from 1875 to 1879 as the E. Anheuser Company's Brewing Association.

Royal Aircraft Factory B.E.9

The Royal Aircraft Factory B.E.9 was a British experimental reconnaissance aircraft of World War I.

Design

The intention of the designers was to combine the high performance of tractor configuration aircraft with a good field of fire for the observer's machine gun, as provided by pushers. It was therefore decided to modify an example of the B.E.2c by adding a small wooden box (which soon gained the nickname "pulpit") in front of the aircraft's propeller, which would accommodate a gunner armed with a Lewis gun on a trainable mount. The normal observer's cockpit of the B.E.2c was removed, allowing the engine (the standard air-cooled RAF 1a of the B.E.2) to be moved rearwards, while the wingspan was increased, and a larger fin was fitted.

A general layout of this kind had various drawbacks - the most obvious being the perilous situation of the gunner - who was liable to injury by the propeller, or to be crushed by the engine in the mildest of crashes. The type was not developed further by the Royal Aircraft Factory (although the French SPAD S.A, of similar concept, saw service) and was soon rendered superfluous by the availability of synchronization gears.
