The People of GreenArrays, Inc.
The people who comprise our team are a multi- and cross-disciplinary group. For example, at least five have experience in silicon design; at least seven have experience in general circuit design; at least 10 are experienced in designing software for our parallel computers, and at least five have a track record of successful embedded and other application software design and implementation in numerous diverse projects. Many of our people have worked with Chuck Moore for decades, and most of us have learned to apply Chuck Moore's approach and methods to programming and to hardware and silicon design, and to make our own contributions back to that approach and those methods.
In addition, our consultants have similarly impressive skills including all of the above as well as extensive experience in other areas including instrumentation and advanced control algorithms.
Our team is versatile, and has a record of successfully and effectively forming project teams outside the geometry of our organization chart whenever appropriate.
Beginning with our Founder and continuing in alphabetical order, the people who are part of our organization, including consultants who wish to be so identified, are as follow:
Chuck Moore, Chairman, CTO
Chuck Moore co-founded FORTH, Inc., in 1973. He developed a Forth-based chip (RTX2000) in the mid 1980s, derivatives of which are still being used widely by NASA. At Computer Cowboys, Mr. Moore designed the Sh-Boom microprocessor and then co-founded iTv, an internet appliance manufacturer. During the 1990s, he used his own CAD software to design several custom VLSI chips, including the F21 processor with a network interface. More recently, he invented colorForth and ported his VLSI design tools to it. Moore served as CTO for IntellaSys during development of the S40 multi-computer chip.

Glenn Sanderson, Analog and RF Engineer
In 2012, Glenn has begun a new career, pursuing his lifelong love of photography on a professional basis. Nevertheless he still shares his expertise with us when it's needed.
This section recognizes people who have generously contributed their time and energy in working with us to advance our cause.
Daniel first encountered the Forth language in 1984 and although his educational background is in chemistry, he has remained intrigued by the language ever since. He received his Ph.D. degree in Chemistry in 2001 from Louis Pasteur University, Strasbourg, France. Since then he has worked for several chemical and pharmaceutical companies and is still active in this field.
In his spare time he is interested in Forth compilers, electronics, particularly embedded systems, mobile robotics, and recently also smart sensors. He occasionally works as a free-lance programmer of embedded control systems using his own versions of Forth.
Since he started cooperating with GreenArrays he has devoted most of his extra time to learning programming in arrayForth and exploring possibilities offered by the GA144 chip. His efforts resulted recently in an app note (AN016) on a PID controller.
Daniel lives in the Czech Republic with his wife, kids, cats and a dog. He likes cooking French food, listen to the classical music and jazz, travel, and enjoy his life. More about Daniel's professional interests can be found at LinkedIn.
Stefan Mauerhofer lives in Grenchen, Switzerland where the famous Swatch is manufactured. He studied computer science at ETH in Zürich where one of his professors was Niklaus Wirth. He is working in a back-office company owned by several Swiss banks. The clearing software he is developing is based on C++ and Unix. At the age of 16 he stumbled over Forth, reading "Starting Forth" and implemented his own Forth for the 6502 on a Commodore CBM 4032. In the year 2011 he discovered first Chuck's colorForth webpage and then GreenArray's. Among his hobbies are astronomy (there is an observatory in Grenchen), hiking in the mountains and being the president of a group of freethinkers.
Stefan visited us in Incline for several weeks in late Summer 2012, completing the work documented in his AN009. Undaunted, he returned to visit us in Cheyenne for several weeks during the Autumn of 2013 and joined us in presenting at Forth Day that year. That was still not enough, so Stefan visited us yet again in April 2015. Stefan's work proved that we could in fact start oscillation in high frequency crystals (~10 MHz). Stefan is a good man and a good friend.
Peter Milford, Ph.D. Parallel Rules Inc., Physicist and consumer electronics consultant
As a physicist, much of Peter's work has been in the development of algorithms for sensors, such as: magnetic sensors, accelerometers, capacitive sensors and imaging sensors. Much of this work has been carried out for clients in the consumer electronics industry, leading to products with high volume production. Often Peter take a concept from initial form, sensor selection, through desktop simulations, lab prototypes and manufacturing test & calibration to high volume production. Peter finds that his broad physics and computing background leads to a full system view of a product and that the sensors are at the center of performance of a product. FORTH and FORTH like languages provide a convenient platform for rapid prototyping and development. Peter has visited GreenArrays to assist in developing Application Notes. See http://www.parallel-rules.com for more details.
Robert visited us in late Spring of 2011 and was a big help in taking data on the G144A12 chips as well as reviewing our documentation from a tutorial perspective.
Ed kindly visited us in Incline Village during April of 2011 to assist in bringing our environmental chamber online and in taking some of the characterization data for the G144A12 chips. We have learned that Ed died unexpectedly on 4 January, 2012. Rest in peace, good friend.
