Jun 05 – Dec 05

Working for Start Corporation, I was part of a small team developing the BCode Mobile Ticketing system. Electronic Tickets were sent using SMS to a mobile phone. The SMS Ticket was via the BCode ticket reader, validated using a web service, and feedback presented to user via a 22cm display.
The BCode reader contained a CCD camera, light source, Wireless broadband interface graphical display, speaker and PC motherboard running Windows XP.

The image was analysed, the BCode located and an OCR engine decoded the SMS message back to an array of numbers. A Reed Solomon error correction algorithm was used to decode and retrieve the original BCode message from the OCR output text. A Web Service call was made to validate the ticket and results displayed to the user. 

I was responsible for the design and development of the BCode reader software, interfacing to reader CCD camera, light source and web service. 

The software was developed using Visual Studio 2003, c#, c++ and Macromedia Flash 8. The image processing was developed in c++ and was time critical in order to provide a timely user experience.

February 03 - March 05.

At Resmed I worked as a software engineer on the ACS2 flow generator. The principal function of the AutoSet CS2 is to detect and normalise Cheyne-Stokes respiration during sleep, by delivering the correct amount of air pressure to the patient’s upper airway. The ACS2 is an embedded mechatronic system consisting of a DC Motor (blower), an Hitachi SH3 Risc process, alarms processor, a flow sensor, two pressure sensors, keypad and LCD display. The software was developed using Nucleus RTOS and the GNU Tool Chain. My roll on the project was to resolve problems with the development environment. I upgraded the GNU tool chain to 3.2, solved problems with the initialisation of global and static objects. I resolved timing problems with the 1Khz data acquisition (of flow & pressure). I resolved timing accuracy problems with the systems real-time tick. I debugged problems with the application data-logging component. Developed instrumentation tools to monitor the embedded application thread stack and message queue usage. I also developed a GDB stub for the SH3 which enable the use of GDB with the target applications.

After the CS2 project I was the software team leader on the VStream flow generator project. This was their first FDA Major Level of Concern (LOC) medical product, a new territory for Resmed. As software team leader, I investigated the FDA submission requirements for a Major LOC Medical product and the development implications. While on the VStream project I implemented prototype therapy algorithms for a range breathing disorders. Resmed scientists developed the algorithms.

I developed a GdbServer, Gdb Insight debugging facility for an embedded linux application  on a Motorola MPC 832.

I implemented enhancements to ResScan a windows hosted patient flow generator data graphical viewing application. This is an international product developed using Borland C++ Builder 5, and Visual Studio. I restructured the ResScan application so it could process data from all ResMed flow generators by interrogating the Flow Generator Meta Data (describes data available from the flow generator).  This enable the removal of hard coded logic specific flow generators.

November 00 – December '02.

Project Outline: Design and develop ATRICS (Automatic Train Running Information and Control System). ATRICS enables signalers to control the path of a train through the rail network via a graphical workstation. ATRICS automatically routes trains through junctions, provides train running information for passenger information display systems and operations control. ATRICS is a 24 hours by 7 days a week; fail safe fault tolerant rail control system.  

My last project was to develop strategies for the seamless upgrade of software and data for ATRICS. The project brief is to identify, specify, design and develop software upgrade and maintenance facilities to assist in online configuration management with a minimum impact on system operation. 

Working as a system architect for Rail Infrastructure Corporation I am currently a software team leader developing ATRICS. This is a hands on role were I design and code as well as supervise a team developers. I also provide technical support to all developers on the ATRICS project.  

The ATRICS Rail Control system consists of a suite of C++ Mfc, Stl applications running on Nt4, Win2k and Xp connected to the control systems network. These applications make extensive use of threads and communicate with each other using Winsock. I designed and maintain the system application framework, which includes inter process communications, utility libraries, message routing, security services, user session management, synchronisation and arbitration between online and hot standby systems. It is within the ATRICS framework the application specific components are developed. 

During the project I: -  

• Made extensive use of UML Object Oriented Analysis and design methodology and Rational Rose case tool  

• Made extensive use of Visual C++ Ver. 6.0 on Win NT 4.0, 2K & XP

• Developed multi thread intensive applications

• Made extensive use of the Windows API

• Developed an Inter process communication mechanism via tcp/ip sockets.

• Made extensive use of STL & MFC.

• Prepared detailed design documents.

• Made design review presentations to developers, management, and customer.

• Successfully commissioned a fully operational ATRICS system

• Developed  multi threaded applications on multi-cpu processors.

• Developed a Visual SourceSafe Software Build Version control tool in Visual Basic 

Working for Rail Infrastructure Corporation I designed the ATRICS Web Rail information publishing system known as OSS (Operations System Server). Leading a team of 4 developers, the fault tolerant 24 by 7 Web server was built using an IIS load balanced Web farm, redundant application and Sql servers. The web farm accepts requests for information, and publishes rail network state information using XML messages. The xml messages are called RailForms. The application servers run a suite of programs that provide a bridge between the proprietary Rail ATRICS control systems and the Web server. Information published to subscribers is queued in MSMQ queues. Information includes train-running information, rail asset status. A map of the rail network can be view via a browser, indicating train-running information and signaling asset status in real time.  

The technologies used in this project were secured session login using secure sockets and certificates. Rail control systems to Web Server bridge applications were written in C++. These applications translate proprietary control system messages to xml, cache the latest state information in a sql2000 database, and pass the received data to a distribution manager for publishing to subscribers. A system component health monitor was written in ATL, C++ using DCOM. The health monitor made the state of the redundant sub systems available to all components and maintenance staff. Message distribution components were written in VB. A Sql2000 database held state information.

During the project I: -

• Made extensive use the UML Object Oriented Analysis and design methodology

• Made extensive use of Rational Rose case tool.

• Made extensive use of Visual C++, VB, Asp, DCOM, COM+

• Extensive use Sql2000 stored procedures.

• Designed an ActiveX control for rendering the rail network map on a browser.

• Designed a subscribe publish system using Http, Xml

• Used IIS, MSMQ, Web Farms, MS Network Load Balancing

• Used secure sockets.

• Supervised a team of developers.

Working for Rail Services Australia as Software Engineer replacing the Sydney and Strathfield Train Describer Systems. The Train Describers' monitor the movement of trains within its area of control, displaying the train descriptions on a Signal Control Panel. The movement of a train between adjacent locations is detected by the system via telemetry from the rail network. The system also automatically routes approaching trains through junctions.  

The Train Describer was developed using Visual Studio ’97 under Windows NT4.0. The system consists of 11 executables communicating via Winsock. Each application makes extensive use threads and interprocess communications.

The project was developed under ISO 9001 / ASA 2167 Quality Standards and Software Development Work Standard Mil.STD 498. 

I was one of the original two analysts that started the project and I was with the project until commissioning. As a team leader on the project, I supervised up to 8 software engineers. I produced the User Requirements Specification, Software Requirements and Software Design documents for a major portion of the system. With a team of developers implemented the system. 

I developed the projects Application framework, Inter process Communications based on Winsock, this enabled one application to call the service of a class in another, and a number of general purpose supporting libraries. 

To assist in complying with the work standards I developed a Project database using Access ’97. The User Requirements were captured to an Access ’97 database.  To meet the project trace ability requirements I wrote a series of VBA macros for word, and Rational Rose to relate software design objects to user requirements. The rose model was exported to the project database and documents generated using word

  During the project I: -

• Extensively use the UML Object Oriented Analysis and design methodology

• Made extensive use of Rational Rose case tool.

            Developed a key alias facility for Windows 3.1. This enabled keys to be programmed with user definable key sequences. When pressed the programmed key sequence would be sent to the windows system queue. This emulated the keyboard reprogramming facility implemented in Ansi.sys under DOS. A keymap dll was developed to detect when particular keys are depressed, locate and send the programmed key sequence to the windows system queue for the appropriate key. A sendkeys dll would translate the key sequence to windows virtual keys and add them to the system queue. Functions where developed to enable AutoCAD ADS programs to reprogram the keyboard, enabling complicated command sequences to be initiated by a single keystroke. Tools used Borland C++ 4.0 and Watcom C10 32 bit compilers.
