A valve is provided that includes a body portion defining a conduit and a control element coupled to the body portion and configured to selectively engage the body portion adjacent the conduit. The controller includes L rows of address tags, wherein each row of address tags includes an M-bits block tag and an N-bits valid area tag. The optimizing system generates object code for a source program which is executed in parallel by generating a plurality of threads. The second separation column is connected to the first separation column in series and connected to the bypass line in parallel. Similarly, generation rules for the information output can be stored in the memory system and accessed by the information output system in order to generate the information output. Reflectance modifying treatment is applied to a first region of at least one of the curved specular reflectors, such that beamable energy that is directed towards the array is viewable from a first subset of the curved specular reflectors only under a first set of viewing conditions.
