A system and method is provided for enabling the reuse of algorithms in multiple application frameworks with no alterations required of the algorithm once it is developed. An upper magnetic pole and a sample-side magnetic pole are magnetically coupled to the respective poles of a permanent magnet that is made of a highly strong magnetic material such as a rare-earth cobalt system or a neodymium-iron-boron system, that is axially symmetrical, and that has a hole in the center thereof. A stop member is removably affixable to the support at the at least one mount location for limiting movement of the at least one gripper jaw wherein the size of the stop member corresponds to a discrete maximum degree of opening of the at least one gripper jaw. Additionally, an adhesive layer is formed on two opposite sides of the conductive film along its conductive direction to increase adhesive areas. Alternatively, an optical switch for alternately monitor the first or second channel signal group is interposed between the deinterleaver and one of the wavelength monitoring circuits, with another wavelength monitoring circuit omitted. Such alfalfa plants provide increased annual yield of high quality forage.
