Method and system for providing a fault tolerant data receiver unit configured with a partitioned or separate processing units, each configured to perform a predetermined andor specific processing associated with the one or more substantially non-overlapping functions of the data monitoring and management system is provided. The process begins with a first step of providing a platelike frame having a plurality of cells, each of which is composed of a main plate and a separate arm. By adjusting the reflectance andor the transmittance of the dynamic optical component, different portions of the incident electromagnetic radiation may be directed from the dynamic optical component for changing the variable device characteristic.
