UPAMD, Please note that participation
such as provided by Stephen below is considered the same as attending the
meeting by teleconference and will count toward or maintain the voting
membership status. Bob Davis Chair UPAMD/P1823 Working Group From: upamd@xxxxxxxx
[mailto:upamd@xxxxxxxx] On Behalf Of Stephen Colclough All, As the teleconference yesterday and today
is starting at 1am in my part of the world, I shall not be taking part. My summary comments on the points under
agenda item VI are: VI. Start to review the overall goals of
the group. Solicit new input. a. Life expectancy of 10 years, hopefully
more Yes - support. b. Same connector for All device and
adapter connections if detached cable Yes-
support. c. Power range >10W – 130W
delivered power to device and is brand, model, and year agnostic Yes- support. What about defining the
voltage output range as well? d. First adapter must work with last device
and last adapter with first device. Standard Compatibility. This is a good goal to have in mind, but I would not
insist on it if it meant that future requirements could not be
accommodated. e. Adapter<->Mobile Device
communications required for higher power safety >7W. Yes- support. f. Standard designed to support
Certification testing of adapter and device (and cable)
Ye- support. g. Continuous communications growth to
support growth of UPAMD capability. Yes-
support. h. Basic power delivery mechanism i. Must support
regular non-battery and battery powered devices
Yes- support. i. Device may be capable of being a source
as well as a sink of power i. To supply power
other devices beyond the USB 10W power range
Yes- support. ii. Able to share
power for mission critical or business critical applications if willing Yes- support. j. Make independent of rapidly changing
technology i. Multiple
battery technologies currently used – no common adapter or battery
voltage Yes. The Adapter<->Mobile
Device communications should enable this to be done. ii. Consider
isolation to meet medical power needs It would be
good to consider this, but I would not be concerned if it was not in the
standard if it was made clear that power supplies for medical use might have
additional requirements to those defined in the standard. This is
effectively a safety requirement in my view and should be covered already by
other standards like IEC 61204. k. Consider future mobile device design
options i. Smaller
profiles, headed for 10mm to 5mm? Different shape devices, non-edge usage Yes- support. l. Connector must not mate with any current
designs – product Safety issue – no confusion Yes- support. m. Apply KISS principle – Keep It
Simple Stupid within the other goals. Yes -
support. n. Environmentally friendly to eventual
disposal Not in favour to be included in this
standard. This is covered by existing and emerging legislation around the
world and I do not believe a specific standard for power supplies is the place
to define those aspects which will influence eventual disposal. Enjoy the rest of the meeting.
