The deacidification of citrus juice with ion exchange resin is described. The apparatus can also record and transmit sound and visual information to the monitoring station and receive sound transmissions from the monitoring station. The actuating assembly is movable by a cutting distance at least equal to a height of the brick. Each of the bus bars includes, among other things, an end portion having a protective sleeve and an air barrier to prevent air from moving between the inner surfaces of the protective sleeve and the underlying surface of the end portion of the bus bar. A principal component analysis analysis sub-module utilizes PCA techniques to determine whether the OES data for a particular wafer differs significantly from an expected normal wafer as represented by the models. Therefore, an arbitrary motion vector accuracy can be achieved without the need to perform additional interpolation stages or increase the complexity of a decoder configured to decode motion vector data.
