Paul,
 
I believe filling in the
voltage options request you sent out would be in violation of antitrust
guidelines. I would recommend that no one on this committee complete the
requested form without reviewing the antitrust guidelines. 
 
According to the guideline
we can discuss relative cost differential of certain options and even then
we need to be very careful.
 I have attached the
IEEE antitrust guidelines and suggest everyone in your sub team look it
over very carefully before having any discussion about cost. 
 
If any cost or price information
exchanges hands that does not meet these guidelines Dell will immediately
withdraw participation from the committee.

Subject: Needed input into Power Subgroup Voltage Options
 
Hello:
 
Per the UPAMD general group meeting
today, I am sending this request for your input into an important criteria
for the Power Subgroup.
 
Attached, please see the 10/7/2010
meeting notes and the agenda for the 10/21/2010 meeting.  We need
more participation as we decide the requirements for valid voltage(s).
 We’ve looked at 5 options described in the attached file.  Please
add your analysis of how each option impacts cost, size, efficiency, etc.
before the 10/21 meeting.
 
So far, the group prefers a single
voltage with a broad tolerance, i.e. 21V +/- 3V.  This broad range
accounts for voltage changes with different cable lengths, pin sizes, current
drawn, etc.  But can a single voltage be efficiently used by products
as different as cordless phones, digital picture frames, laptops, printers
and external storage devices?  Would it be more cost effective to
require sinks to regulate input voltages that may vary between 18V and
24V or to put the burden of voltage regulation on the power adapter such
that the voltage at the sink is always 21V?  Creating a power adapter
that can change its output voltage adds complexity, but may offer energy
savings.  These are the issues we would like you to address in your
analyses in the attached template.
 
Your participation is important.
 At the next Power Subgroup meeting, we will review your analyses
and work towards a conclusion of the ideal voltage requirements for this
spec.  From there, we will draft voltage and power criteria to be
voted upon.  Then, we will look at issues surrounding the remaining
goals including power for communications, ability to be both a sink and
a source, power for both battery and non-battery devices, operation with
unstable sources of power, 
 
Next Power Subgroup Meeting:
7am Pacific, Thursday, October
21st
10am Eastern, Thursday, October
21st
3pm London, October 21st
10pm Taiwan, October 21st
11pm Japan, October 21st
 
See you on the October 21st
meeting.  And, thanks for your input.
 
Regards,
 
Paul Panepinto
