Data frames, such as Controller Access Network frames, that are to be programmed into a FLASH memory device, are sent from a programming station to a target device via a relatively high-speed bus and stored temporarily at the target device in numbered frame buffers. The feedstock is contacted with water in the presence of an acid catalyst. The housing may be moved to the opening through the vasculature, utilizing a guidewire, steering catheter, or other mechanism. They may be aqueous with a matrix consisting of an aqueous gelled network. The apparatus further includes a saturated fiber power amplifier optically coupled to the fiber-coupled amplitude modulator. In a medium that recordsplays back data including video data and control information, the control information includes information for accessing a specific portion of the video data.
