"and could only figure, our Micro OS was the reason for the battery life on eVu --a very efficient OS system, that saved significant amounts of battery power"

The issues considered for MOS are efficient in saving power ...e.g for their operating system they do not manage virtual files which reduces RAM resource by a very significant amount, along with other efficiencies.

For their audio and video Applications they are separate considerations composed around the efficiencies of the operating system.....with that, these applications, among others, yield power efficiency....Where the applications of others not composed around this atmosphere are not as efficient, ... requiring their assorted resources.

As far as applications go, it's safe to say audio and video are locked up by e.Digital under their patented methods.

Now you add the "control circuitry 21/processor 21 and specific patented novel circuits " of 774 to the mix and these considerations add to the power efficiencies.

There are may moving parts to e.Digitals repertoire, where collectively, they form a whole new ecosystem of computing able to be configured to any environment.
