I started programming at MIT when Spacewar was a new game! My
skills grew with the field. I spent more than 15 years at DEC
designing computers and building CAD tools to help others design chips
and computers.
When I left DEC I consulted for several years and then helped found
NetPhone where we made a telephone system on a single card.
I was the Director of Software Development and wrote the embedded phone system software. (Patent
5,875,234
is primarily the work of myself and Steve Staudaher the NetPhone hardware designer.)
The phone system server was controlled by client applications, which communicated with it over the network.
NetPhone got sold to Sonoma Systems and Nortel then bought Sonoma.
Before, during and after my corporate embedded career I did freelance work.
This work usually involved combining programming skills with my human interface design skills.
I developed software for the leading
Air Data Computer
for sailplanes. I wrote programs to typeset an annotated bibliography.
Later I evolved an interest in Web publishing, especially the infrastructure for small data driven applications.
The Photo Library and
Mailing Lists
of this site are examples of such applications.
Another application I built is used at
www.flavorandfortune.com.
Among other tasks that site presents book reviews and articles out of a database. The application allows the
site managers to add and remove reviews without writing web pages.
I then became involved in Mesh Networking: Using
groups of computers each with a low power radio. These computers cooperate in
sensing and data communications applications. My first work in this
area was at Sensicast Systems.
As a co-founder of
Wireless Sensors, LLC I
acquired a license to the Sensicast technology and adapted it to the
Data Center market. Wireless Sensors is now delivering systems that
monitor environmental parameters to this
market using wireless
networking.
The work at Wireless Sensors and Sensicast created an interest in what is now called
"The Internet of Things".
At Waters Corporation I
ported a large emedded application to an
Altera NIOS2 FPGA based
embedded platform. I then brought up this system and demonstrated
complete instrument operations. The instrument must meet FDA
standards for a Medical Instrument. This system runs motors,
collects samples from vials and performs Chromotographic chemical
analysis on the samples.
At Erallo Systems I was
involved in many Wireless sensor projects. Featured on the web site is
the
Wearable Body Unit.
I wrote the
TinyOS embedded software that runs
in this device and developed the server software that the Body
Unit reports to. Also at Erallo I developed a prototype
Scale Logging system. This system is a good example of how to use HTML and PHP
to report data to a server.
I am expert with
802.15.4 radios, having written drivers, messaging services, network
protocols, test and evaluation software etc.
I have worked for
several large players in the field including
Sensicast ,
Crossbow
and
GE Global Research.
The work with GE resulted in an IEEE paper. At
Sensicast I built mesh routers and sensing systems for a
variety of tasks including
CMU's Lancaster Farms
irrigation sensing,
vehicle tracking
systems and motor condition monitoring. I also had a leading
role in Sensicast's
artwork monitoring
and
OEM sensor
systems. One project at Sensicast will monitor sewers for overflow on a mesh
network that must span a city. At Sensicast I built a set of I/O cards
that enable Sensicast's
Smart Sensors.
