Abstract: A system and method to transform a block of data is disclosed. A block of original data is retrieved from a data store, block of original data including a N number of words, each word including one or more bits of data. A multiplier matrix is provided, the multiplier matrix having N×N words, a plurality of sub matrices arranged diagonally within the N×N matrix, with each of the sub matrix arranged as a binomial matrix. All the words in the multiplier matrix not part of the sub matrix are set to zero. Each of the sub matrix is represented as a product of a plurality of lower factorized matrix, a plurality of upper factorized matrix and a shift matrix. The block of original data is multiplied with the multiplier matrix to generate a transformed block of original data with N number of words.

Abstract: A system and method to encrypt a block of data is disclosed. A block of original data is retrieved from a data store, block of original data including a N number of words, each word including one or more bits of data. A multiplier matrix is provided, the multiplier matrix having N×N words, a plurality of sub matrices arranged diagonally within the N×N matrix, with each of the sub matrix arranged as a binomial matrix. All the words in the multiplier matrix not part of the sub matrix are set to zero. The block of original data is multiplied with the multiplier matrix to generate a block of modified original data with N number of words.

Abstract: A loudspeaker is disclosed. The loudspeaker includes a diaphragm with a fixed portion and a movable portion. The fixed portion is attached to the movable portion by a plurality of leaf springs disposed between the fixed portion and the movable portion of the diaphragm. A coil is disposed over the diaphragm in the movable portion of the diaphragm. A magnet assembly is operatively disposed relative to the coil, wherein upon flow of current through the coil, the movable portion of the diaphragm moves relative to the fixed portion.
