The IEEE does not accept requests for applicant-specified
identifiers.
The URN is a 64-bit unique identifier utilized
to ensure unique access to IEEE 1451.4 TEDS memory
devices arranged in a multi-drop two conductor
network as described in IEEE Std 1451.4-2004.
(see IEEE Std 1451.4.2004 subclause 5.4, figure
2) Users purchasing commercially available node
devices for use in their products do not need
additional URN codes, since a URN is contained
in each purchased device.
Organizations wishing to design devices emulating
the operation of commercially available nodes,
with an ASIC or micro-controller for example,
for use in 1451.4 systems, must obtain URN codes
for installation, one per device. The IEEE 1451.4
URN is arranged as below. The system reads the
URN least-significant bit first.
The IEEE Registration Authority will assign blocks
of 4,096 individual URN's to any organization,
from the IEEE pool of 68.7 billion blocks. The
IEEE will assign up to 10 blocks per purchase.
NOTICE: As the end user, there may be intellectual
property issues associated with the use of the
Unique Registration Numbers (URN) that you are
responsible to ascertain and satisfy. The issues
may require that you purchase a license(s) and
pay a royalty to third parties who claim ownership
to said intellectual property. It is strongly
recommended that before you purchase a URN, you
review the IEEE Standards Association patent database
at http://standards.ieee.org/db/patents/index.html
to obtain some of the information that may be
relevant to obtaining your URN.
