The disclosure relates to a trusted interface unit and a method of making and using the same. According to one embodiment of the present invention, a method of transmitting data on a network may include receiving data from a partition within a node on the network. This node may be configured to transmit data associated with a number of sensitivity levels. According to one embodiment of the invention, these sensitivity levels may be classification levels. One method of transmission of data may include determining the identity of the partition that originated the data within the node. Furthermore, a label may be added to the data received from within the node and the data may be encrypted with a key that may be uniquely associated with the label on the data. After encryption, the data may be transmitted on the network. Additional methods including the reception of data are disclosed. Various node and network architectures are disclosed implementing the methods and apparatus of the present invention.

Trusted interface unit (TIU) and method of making and using the same

A magnetic flowmeter with an improved liquid conduction indication has a flowtube assembly with a passage for liquid flow and has an electromagnet mounted outside the passage that provides ramped magnetic excitation. An electrode circuit couples through the passage and generates ramp spikes and a flow signal. A processor receiving the flow signal and generating a flow rate output. The processor also receives the ramp spikes and generates a filtered integral of the ramp spikes as a liquid conduction or empty pipe indication.
