Abstract

These teachings present triple data transport redundancy in the form of three data bus interfaces that are each designed and manufactured independently from one another and compatible with a common data handling protocol. This protocol can be one that includes no error correction. These interfaces can each couple to a corresponding first, second, and third data bus that may comprise optical data busses. Information gauges can be realized through use a memory that stores a plurality of images comprising views of an information gauge (or gauges) of interest showing a variety of different readings. Upon receiving information regarding a monitored parameter of interest (via, for example, the aforementioned data busses and data bus interfaces), this information can be used to address the stored information gauge view that corresponds to the present parameter value. That particular view can be recalled and displayed to thereby provide the corresponding information to a viewer.
