Power states

Devices and Sensors Working Group--
  Greetings. I have followed this list for several years but have not
contributed at all recently or at all.
  I see that the current scope includes power status and power state
transitions for the screen and device.
  I have worked on communication protocols related to power state and wrote
an IEEE standard (1621) on how power state information should be presented
to people. I have worked on test procedures and energy efficiency
specifications about power states, and worked on various standards that
include power states in multiple standards organizations.
  I would welcome a discussion (zoom?) on power state terminology. I hope
someone can provide me guidance on how best to contribute.
  For substance, some key conclusions are:
-There are three basic power states: On, Sleep, Off
-Avoid the term Standby - it is inherently unambiguous and untethered to
any particular meaning
-Basic states can have substrates
-Devices only exit a power state with a power control (on the device, over
the network, or an internal timer); devices may wake from sleep for many
reasons
Thanks,
--Bruce
