Marconi Northstar
Division- Acton MA. needed to update their aircraft Loran navigational
system. The new system needed to meet a more severe FAA requirement and also be able to
communicate with a Global Positioning System (GPS) sensor as well. The project on this was
implemented with a mix of assembler and c language programming. It also involved writing a
protected mode operating system for an 80386 chip from scratch.
Motorola / Codex Corporation- Mansfield MA.
needed an HDLC communications stack built from scratch to run on a communications
coprocessor card plugged into an IBM PC ISA Bus. This board ran the Hunter and Ready VRTX
(UNIX on a chip) operating system. The product was compiled using cross compilers that ran
on networked UNIX Workstations. |
General Electric
Corporation- Lynn MA. was routinely ruining work while machining large
components to produce jet aircraft engines. The problem was that old versions of the tapes
that ran the numerical controlled equipment. The solution was to implement a system that
downloaded and held a shift's worth of work directly from the factory's CAD/CAM host
computer complex. An additional feature was added to allow shop manuals to be embedded in
the G Code streamed down from the Hosts. These step by step manuals could be scrolled to a
screen to aid the machinist operators.
Andlinger / Polaroid Grapics Imaging - Waltham & Bedford
Ma. needed a systems architect to design and engineer their pSOS based, high
resolution, digital proofing system. The system out performed the earlier crippled legacy
products by orders of magnitude. This was accomplished with orderly thread synchronization
through a series of table driven finite state machines. |
