Hi Russell:

Some comments about "Off".

I have within arm's reach a Harbor Freight (made in China) digital vernier 
caliper that seems to eat batteries.  Then read a web page that had 
demonstrations that proved that all the "Off" function did was turn off the 
LCD.  All the rest of the functionality runs as long as the battery is 
installed.  The Japanese calipers actually turn off and their batteries last a 
very long time.  I've got quite good at pulling the battery.

I've been monitoring my sleep using a G-Pendant from Onset Computers for 3 
months about 10 hours per day on the same 2032 battery. [PIC] It uses a 16F690 
and the Analog Devices XL330 3-axis accelerometer.  Very cleaver design that 
uses an optical I/O via USB.  A magnet is used to signal that I/O is desired 
and can trigger the start of data logging.   Has no "Off" switch, but when not 
logging a LED flashes very briefly with a period of 8 seconds.

I've read that here in California there may be rules on the way that will 
specify how much power is consumed by "Off" electrical equipment.
