A system provides referencing from one file system server to another through the use of a file system location database, improving movement and replication of file systems. Various device embodiments comprise at least one pulse generator and a controller to communicate with the pulse generator. The engine cylinder is also ported to optimize performance. The IOL may have an optic and leading and trailing haptics coupled to the optic, and the holding station may be capable of manipulating the haptics as desired to facilitate transfer of the IOL through the delivery tube into the eye. An inserted controller generates clocks and various control signals. The contact structure is formed of a contactor carrier and a plurality of contactors.
