A shower head with a housing and a jet outlet surface can be achieved with an example embodiment of the invention. A second hard bit of a second logical page is sensed. A 16Kc version utilizes bitmaps to compress the table to less than 0. The separable second latching modules are engageable to the separable first latching modules to mate the first and second fiber optic connectors. The container auto-lock system is configured to be compatible with international sized container by allowing the inboard apertures on each lower casting to be available for attaching the domestic container on top of an international container with a conventional locking device.
