A method and system of masking a group of related data values. An operator controls a machine hydraulic function using the electrohydraulic operator controller, the feedback system senses a property of the hydraulic function, and generates tactile feedback in the electrohydraulic operator controller based on the sensed property. Additionally, the AMA device may also have a greeting player and message recorder element that queries an announcement database, and a content adapter element that queries a message format requirement database. A clamping surface is moveably connected to the bevel arm and configured to engage the locking surface. Finally the spectra obtained are correlated to the reference data stored in the computer to obtain a rapid measurement of the analysis desired. The first layer provides technical properties to the fabric, and the second layer provides the fabric with desired aesthetic properties.
