A memory card detection method comprising detecting insertion of a memory card into a device’s card slot; creating a memory card construct in a non-volatile memory storage; copying data from the memory card to the memory card construct; and informing the device that a new memory card has been inserted and may be accessed from the non-volatile memory storage. Each bus agent is assigned a weight that governs the percentage of bus bandwidth allocated to the agent. Retraction of the penetrator closes the poppet valves, sealing the pressure barrier, severing the line and allowing the tubing hanger to be pulled. A ring is attached to one of the legs remote from the base and has a tab for coupling with the opposite leg to complete the structural volume.
