LonWorks or Local Operating Network is an open standard (ISO/IEC 14908) for networking platforms specifically created to address the needs of control applications. The platform is built on a protocol created by Echelon Corporation for networking devices over media such as twisted pair , power lines , fiber optics , and wireless .
LonTalk is a networking protocol. Originally developed by Echelon Corporation for networking devices over media such as twisted pair, powerlines, fiber optics, and RF.It is popular for the automation of various functions in industrial control, home automation, transportation, and buildings systems such as lighting and HVAC (such as in intelligent buildings), the protocol has now been adopted ...
Echelon was founded in February 1988 in Palo Alto, California by Clifford "Mike" Markkula Jr. [1] The chief executive was M. Kenneth Oshman.Echelon's LonWorks platform for control networking was released in 1990 for use in the building, industrial, transportation, and home automation markets.

In linear algebra, the Hermite normal form is an analogue of reduced echelon form for matrices over the integers Z.Just as reduced echelon form can be used to solve problems about the solution to the linear system Ax=b where x is in R n, the Hermite normal form can solve problems about the solution to the linear system Ax=b where this time x is restricted to have integer coordinates only.
In 2017, the Justice Department characterized him as being an "upper echelon (associate) of Russian organized crime". [112] Living in Vienna, Austria, for five years he has been fighting extradition to the U.S. on bribery and racketeering charges, and has been seeking to have the charges dropped.
The concept of a coarsely-ruled grating used at grazing angles was discovered by Albert Michelson in 1898, [1] where he referred to it as an "echelon". However, it was not until 1923 that echelle spectrometers began to take on their characteristic form, in which the high-resolution grating is used in tandem with a crossed low-dispersion grating.
The term echelon comes from the French échelon ("level" or step of a ladder), and refers to the fact that the nonzero entries of a matrix in row echelon form look like an inverted staircase. For square matrices , an upper triangular matrix with nonzero entries on the diagonal is in row echelon form, and a matrix in row echelon form is (weakly ...
