A magnetoresistive random access memory has separate read and write paths. Each client device has a network interface, an engine for processing media data, and a media interface. The backup server merges the received backup tables to form a merged backup table. With this structure, no clamping hardware is needed to secure the lines together nor are any anchoring brackets required to mount the lines to the vehicle or its components. In an alternative embodiment, the male coupler includes a snap-in element to engage the male coupler with the coupler. A control circuit is provided for controlling said switch, and a zero inductor current detection circuit is provided that compares a voltage on said connection node with a reference voltage and provides a zero inductor current indication when both voltages are equal.
