Embedded Systems Development
DelSys has successfully completed numerous embedded systems development projects. We have experience with a variety of embedded technologies:
- ARM, TI, Motorola and Intel MPUs
- IAR Workbench, TI Code Composer, Keil µVision
- Cross development in C, C++ and assembler
- No kernel, micro-kernel and RTOS architectures
- Bluetooth, USB, TCP/IP, CAN, RS-232, RS-485
- Device I/O, driver, interrupt services
- Hardware diagnostics and board bring-up
- Low power systems, small memory spaces
- Motion control, robotics
- Boot loaders
For J & J, DelSys developed firmware for several generations of a medical instrument over a period of 10 years. These instruments were extremely reliable – zero software defects were identified in the field.
For Scientific Games Corporation, DelSys developed firmware for point of sale terminals and data communications devices used in their ultra high reliability wagering systems.
Web Application Development
Client Side
- HTML, CSS, JavaScript, jQuery, AJAX
- Graphic design, fixed and fluid layouts
Server Side
- LAMP – Linux, Apache, MySQL, PHP
- WordPress – themes, plugins
Windows Development
- Visual Studio, .NET, C#, Visual Basic
- C++, WinAPI
Linux Development
- Linux®, Unix®, LynxOS®, QNX®, etc.
- Eclipse, Gnu Tools, C, C++, make
- Scripting, command line tools
DelSys developed the software for a sophisticated Windows database application used for personnel scheduling in complex 24x7 scenarios.
DelSys developed system software for a medical instrument used for human blood testing. The software was written in C and ran on the QNX RTOS.
Mission Critical Systems Development
Mission critical software functionality and reliability must be flawless. If the hardware or power fails, the software must limit the consequences – continue to run with reduced functionality or shut down safely without loss of data.
Mission critical reliability demands craftsmanship in all phases of development – requirements, design, coding, testing and deployment. DelSys has extensive mission critical systems development experience:
- Medical and laboratory instruments
- Financial and wagering systems
- Satellite data communication and cable television systems
Mission critical style development is cost effective – reduced support and maintenance costs allow future development to focus on new products and features instead of bug fixes.
Medical Systems Development
DelSys has extensive experience developing software for medical systems on embedded, Windows and Linux platforms:
- Clinical laboratory automation systems
- Clincal chemistry instruments
- Intravenous blood treatment instruments
- Insulin pumps
- Investigational prototype systems
DelSys understands the disciplined, well documented development processes mandated by the FDA Design Control Guidance. DelSys complies with and participates in the client's quality control and regulatory processes.
Client Solutions
Prototype Development
DelSys managed projects and developed software and firmware that delivered prototype devices used to investigate technologies for a new medical instrument.
QA & Consulting Completes Project
A laboratory instrument couldn’t be sold because the software was unreliable. DelSys was retained to redevelop the software. But we completed the project more quickly and at lower cost by working with the in house team to renovate the existing code.
Banking Interface Redevelopment
The interface between a Windows client and a Linux back end was slow and unstable. DelSys designed a fast, reliable interface and reduced the amount of code by half.
Installation Support & Field Service Training
Early installations of a new medical system were challenging because the system was difficult to integrate with hospital IT systems. DelSys provided onsite support for early installations in the US and Europe to ensure successful installations. And then provided training for the client's field service personnel that allowed these systems to be installed quickly and reliably.
