ispark software support transition:
in march 2021 PTB retired from ispark software project giving
back all intellectual and commercial rights to me as the sole
ispark software author and producer.
As a result, some rearrangements with sales and support were
necessary.

new ispark software key:
A most up-to-date Sentinel USB key is enclosed now with ispark
software licenses. This strongly reinforces ispark software
applicability with coming Windows OS versions, particularly no
proprietary drivers and no installation procedure is needed any
more.

pleasant news with ispark software

Researched and developed from 1995 to 1999 by M. Krämer,
ispark algorithm was implemented in software.
As a first step this software was used to generate a set of
diagrams for manual evaluation of IS circuits in a graphical
manner. These firstly were published as PTB Report ThEx-10
in 1999.

Next step was the completion of ispark algorithm code to get
ispark software for everybody's use until 2002, offering much
faster, comfortable and versatile use.
In 2023 finally, the graphical representation of ispark algorithm
reaches IEC 60079-11:2023 as normative annex G.
