Employment History

    President, Digital Design Inc. (US registered company) Apr 2005 to Present

Responsible for all technical and administrative functions, as well as software development,

    systems administration, and IT management.

Maintained and evolved the websites for my software products (see below).

    Maintained and evolved the supporting Linux servers, and VPNs in both the United States and New Zealand.

    Built an Asterisk PBX running on a Linux platform, using SIP and IAX devices on the VPN, and interfaced to my business phone numbers via Broadvoice.

    Evolved the supporting software for my software products into a fully modular e-Business tool suite, built in C++ and running on Linux servers. The system automatically performs all

    business functions; sales, online payment processing, and generation of invoices / receipts /

    credits, managing customer accounts, periodic rebilling for subscriptions, right through to

    generating the daily import files for QuickBooks.

Developed software for internet download websites. C++ running on Linux/Apache. The

    system is fully automated, with the customers being able to make single purchases, or charge

    multiple downloads to their credit cards.

    Developed PC based entertainment / marketing software under the name of Musical Vision. This combines animated sequences of images, set to music, that companies could

    give to clients on a USB Flash Drive, or download from their websites. C++ under Windows,

    developed under Microsoft Visual Studio (MVS).

For software testing purposes I built two 'Schiz' machines, able to be rapidly switched to any

    given OS and any given service pack level. They currently support everything from MS-DOS

    2.11 through to Vista and Windows 7, and all modern Linux distributions. They also allow me

    to test websites under all browser types and versions.

President, Digital Design Ltd. (NZ registered company)

    Oct 1991 to Apr 2005

I developed HeliNav, a new navigation system for helicopters and tiltrotor aircraft such as

    the Bell/Boeing V-22 and Bell/Augusta 609. The software was written in C++. It dynamically computed - in flight - the routes and all obstacle clearance requirements, using the GPS position of the aircraft, Digital Terrain Models (DTMs), and obstacle databases.

At the time it was described by the FAA as the most comprehensive and complete system

    that they had seen to date. It culminated in an invitation to Washington DC by the FAA, where I put on presentations to FAA, NASA, and various industrial groups in 1996.

Being a New Zealand registered company I was unable to secure funding, and the project

    died.

Developed a number of downloadable applications for PCs, sold over the internet. This

    included Time Zones for PCs?, Remote Control for PCs, and The Metric Conversion

    Calculator.

Time Zones for PCs? allowed individuals and businesses to see the CORRECT local time

    anywhere in the world (there are around 252 individual time zones in the world, and there are

    changes to the various daylight saving rules around the world almost every week - so it is not

    trivial if it is done properly). It also allowed people to plan ahead and coordinate times for

    international conference calls.

    For a number of year it sold reasonably well, with customers including Boeing, MasterCard Europe, E! Entertainment Television, Raytheon, and even the US Strategic Command.

    The work not only involved the products themselves, but the websites, marketing, and all the supporting internet infrastructure including 3 servers running Linux and Apache.

I also developed the entire product sale / download / registration / product update software

    that ran on the servers (C++ running under Linux).

    Rather than being sold outright as a product, because of the frequent data changes Time Zones for PCs? was sold on an annual subscription basis. It was probably one of the first of

    what is now known as SaaS (software as a service).

Assistant Navigation Services Specialist, Navigation Services Unit,

    Airways Corporation of New Zealand Ltd.

    Feb 1990 to Oct 1991

    Our unit was responsible for maintaining New Zealand's system of Instrument Flight Rule (IFR) navigation routes, approaches, and departures to international ICAO PANS-OPS standards.

I designed a number of new routes, including two down to Antarctica.

    I also developed software in C++ to scan multiple Digital Terrain Models (DTMs) and perform all the route calculations. This reduced around 7 days of manual work down to just a few

    minutes.

President, Digital Design Ltd.

    Mar 1987 to Feb 1990

    Developed the hardware and software for 80X86 and Z80 based real-time embedded systems. This included:

    ? circuit design

    ? PCB design, often using STE (the small brother of VME)

    ? design and programming of FLPDs, and Altera EPLDs

    ? firmware, written in assembler and involving multithreading and multitasking

    techniques

    ? DOS application programs, C and 8086 assembler

Specific Equipment:

    ? data protocol converters

    ? print spoolers and switches

    ? alarm controllers and security systems

    Technical Services Division, A.W.A. (New Zealand) Ltd. Apr 1985 to Apr 1987

A.W.A. had the New Zealand agency for companies such as Koden, Trimble Navigation,

    Hitachi, Oki, as well as producing products under our own name.

Our unit installed the first GPS system in New Zealand (at a cost of $60,000). This was a

    large fishing vessel and they recovered the cost on their first catch.

    I was responsible for the repair and customization of data systems (computers, printers, and networking products), as well as working on marine equipment (radars, sonars, net monitors, weather faxes etc.), and radio equipment and avionics as required. Some work was in the workshop, some was at the customer's site, or in the case of marine, on board their

    ships.

I supervised three other technicians.

Physics and Engineering Laboratory, Department of Scientific and

Jan 1982 to Apr 1985

Under the DSIR's technical training program I was rotated through the following sections, until Industrial Research (DSIR)

    being permanently placed in the Electronics Group.

Electronic Design Section

    Design of analog, digital, and microprocessor circuitry for original scientific equipment used by other branches of DSIR.

    PCB design, PCB assembly, equipment construction, and environmental testing of equipment to international standards.

Specific projects: Designed and built an interface/controller card for DSIR's vibration testing

    rig, built equipment for DSIR's silicon wafer facility, rebuilt a eupathioscope for simulating the heat signature of the 'standard' human.

Thick Film Section (miniature electronic circuits)

    Thick film is the process of screen printing multilayered conductors, resistors, and insulators onto a small ceramic substrate to develop miniature hybrid electronic devices.

    Trained in the use of all techniques and equipment; screen printers, furnaces, bonders etc., and generating the rubylith masters.

    At that time the plant was producing the substrates for the DSIR designed SSB emergency transceiver.

Temperature Standards Section

    The Temperature Standards Section maintained New Zealand's temperature standards, built equipment to support that role, and calibrated client's thermometers, thermocouples, and other temperature sensors to international standards.

Specific projects: Designed and built a temperature controller PCB for a new oil bath that

    was being built. Assisted in a number of calibration jobs.

Remote Sensing Section (satellite image processing)

    Developed software to simulate a chopper front end for a new type of infrared detector for

DSIR's Hand Held Radiometer. The HHR was used onboard a number of Space Shuttle

    flights.

Researched and produced a study on liquid crystal shutter techniques, again for the HHR.

Photometry Section

    The Photometry Section maintained New Zealand's light standards.

    Specific projects: Maintained the section's equipment, and did various calibration jobs including pyranometer calibration.

Drawing Office

    Trained in electronic and mechanical drafting techniques, and all the processes of a drawing

    office.

    Specific projects: Circuit diagrams, mechanical drawings of equipment produced by our various machine shops, and diagrams and charts for international publications.

    Outside Interests

Flying airplanes and helicopters. I used to be in a formation team in New Zealand. We

    competed with other teams, and put on displays at air shows.

Ballroom, latin, and swing dancing.
