Research and Development Software Engineer
Wood & Douglas Ltd, Tadley Jul 2002 - Sep 2005
After completing my Computer Systems Engineering BSc Degree I started fulltime employment as a Research and Development Software Engineer working on a range of Radio Frequency products.
The radio electronics were configured, controlled and monitored by Microchip PIC Microcontrollers running firmware written in embedded C by me. I also produced Microsoft Windows C++ Graphical User Interface applications for setup, control, monitoring, and automated test of the radio products.
This position involved being part of the Research and Development design team through from initial concept, through rapid prototyping, to creating final production code and supporting through test. The following products contain firmware developed by me:
An intelligent antenna mast mounted Radio Frequency Down Converter to convert from frequencies in the 2.4GHz L-Band microwave frequency range down to VHF to reduce loss in cables and allow use of standard tuners.
Digital Video for Moving Objects:
A complete product family including a video encoder / transmitter unit, a receiver / video decoder unit, an IP data adaptor, a battery powered portable receiver with in-built LCD screen, a pre-set profile switcher, and a Microsoft Windows Graphical User Interface application.
Dräger PSS Merlin:
The Dräger PSS Merlin is a telemetry system used by US Fire Fighters to monitor status and communicate it to the Entry Control Board to increase safety while firefighting. A bidirectional data link remotely monitors Manual distress signal, Automatic distress signal (triggered by lack of movement), Oxygen cylinder pressure, Oxygen Time to whistle, and Elapsed time spent in the fire for each Fire Fighter, and allows the Incident Commander to issue an individual or team evacuation signal from the Entry Control Board.
