Hi List,
 
I was wondering if anyone has provided a battery backup for the 1wire power.

As I expand and use more of the BAE910 intelligent slaves it becomes a good
option  to keep these devices powered during power outages. 
 
I have two USB adapters one has a hub installed and the other has sensors
directly connected.  
 
HUB    I know the hub has an onboard power connection and voltage regulator
inside so I suppose this should be easy, however really wanted to somehow
just use a battery pack and some diodes.
Direct connect to USB  ...This maybe a little more interesting as I
currently use the USB power for the network 
 
 I was probably hoping to keep it real simply and use a couple of high
quality AA batteries in a battery pack to provide say 4.5VDC.  I know my
problem will be the ADC within he BAE910 as I assume it references the
supply.
 
Has anybody got a simple battery backup on their network to keep the sensors
alive ?
