One example embodiment includes an atomic sensor system. Methods and structures are described to provide slew rate control of an output driver circuit such as a DRAM output driver on a die. While attemps have been made to protect such digital content, none of the existing protection techniques have been successful. Once the legs of the collar have been selected the collar package may be listed on the exchange, and orders for the collars may be processed by matching orders for opposite positions in the collar. This reduces non-specific binding of IgG’s from the serum to the solid phase surface and thereby reduces the occurrence of false positive readings in the immunoassay. In this way, improved use of this data is made possible.
