    • Yes, and ABB has been a customer for a while too. Look at this customer list from 2001. There are lots of multi-billion dollar sales companies on the list.

      All buttoned up? Gee, less than a month ago another thread member posted that the Current Sensor was DOA.

      Martin said earlier that the announcement was coming and revenue 6-9 month later. We thought it was completely dead. Now we see it WILL become a product. 6 months? 9 months? Longer? Who can say? The point is it WILL come now.

    • Maybe so...


      ABB Australia wins High Commendation for fibre optic current
      transducer

      Sydney Australia, 29 November - ABB Australia, part of the global power and
      automation technology company, announced today that the fibre optic current
      transducer (FOCT) it has been co-developing with the Australian Photonics
      Cooperative Research Centre in Sydney has won a prestigious High
      Commendation in the Innovation and Inventions category at the 2001
      Engineering Excellence Awards of the Institution of Engineers, Australia.

      The FOCT development won the award against 15 other contenders, all of them
      large-scale institutional entrants. It also won an Excellence Award from the
      Australian Electrical and Electronic Manufacturers��� Association (AEEMA) in the
      Environmental Products category in 2000.

      The FOCT is the result of a development project led by ABB in co-operation with
      TransGrid, the NSW high voltage electricity network owner and Australia���s largest
      electricity network service provider, and the Australian Photonics Cooperative
      Research Centre based at the Australian Technology Park in Sydney.

      The transducer is a novel optical fibre and digital processing system that measures
      changes in the phase-shift of a light source caused by the magnetic field produced by
      the electrical current in high voltage networks. The system then analyses light from
      the sensor to measure the magnetic field and hence the current in the high voltage
      circuit. The configuration of the sensor coil minimises the interfering environmental
      effects of temperature and vibration.

      The wide dynamic range of the FOCT makes it the first system of its kind to offer a
      practical solution for driving protection, control and metering devices from a single
      transducer. In addition, because its performance is not limited by the geometry of the
      coil, it is suitable for a wide range of high voltage applications.

      Its accuracy, bandwidth, dynamic range and environmental performance are
      equivalent, and in some areas, superior to conventional current transformer
      technology, and well able to meet the demands of new electricity markets. At the
      same time, it is compact, light and therefore has potential to be easily integrated with
      other high-voltage equipment.

      Its benefits also include reduced use of resources such as steel support structures,
      concrete foundations, copper cabling and insulation; reduced generation of
      environmentally sensitive waste products; improved isolation of secondary systems
      in substations, and lower transport and installation costs.

      The FOCT is the result of seven years��� co-operative research through the CRC. Key
      members of the team included Margareta Bjarme, who was seconded from ABB in
      Sweden to project manage the research; Dr Ian Bassett from the University of
      Sydney (CRC); Tony Lee, project coordinator from ABB Australia, and John Hoore
      and Steve Jones from TransGrid.

      Having passed performance tests in laboratory and field trials a pre-commercial
      version of the FOCT has been installed at a TransGrid substation since July 2001
      and is recording excellent results.

      Douglas Pitt, Senior Vice-President, Utilities Division, ABB Australia, said: "The
      project demonstrates the ability of ABB researchers and engineers to co-operate
      across institutional, company and global boundaries to produce world-leading
      technology wherever they may be."

      ABB (www.abb.com) is a global leader in power and automation technologies that
      enable utility and industry customers to improve their performance while lowering
      their environmental impact. ABB has 160,000 employees in more than 100 countries.

    • Hi, Sector. I did expect a little stronger language in the announcement. Not that I'm looking a gift horse in the mouth -- I'm glad there is an annoucement to complain about -- but given the time that has passed since we first heard about the current sensor, I would hope that the product would be all buttoned up. If all that was left to be done was tweak the casing, move the screw-holes, etc., KVH would be well aware of the capabilities of the core product and wouldn't need the "is expected" language. The fudge language in this regard leads me to believe there are still some performance issues to be tackled. I hope I am proven wrong.

      Regarding the six-to-nine month time lag before revenue shipments, my post was suggesting that I expect the longer end of this frame, and perhaps even a little longer, before any material impact given the "is expected" language in the announcement, coupled with ABB's apparent "what's the rush?" attitude. Maybe ABB just had some soon-to-be obsolete current sensor inventory to clear out before this annoucement was made. :o) Again, I hope I am proven wrong.

      Anyway, as usual, I'm just nit-picking. We are still heading in the right direction, although, I maintain, a little more slowly than perhaps we would like.

    • Product Development Agreement.... hmmmm, what does that mean? Are we still in the development stage of the current sensor? I was under the impression that was already taken care of.
