| Medical |
| Sterling's roots are in the medical industry and the majority of our
projects have been directed towards the creation of devices or systems for medicine. It is in this
industry that we claim our greatest expertise, not only in the application of technology but in
our understanding of the needs of the customer. Specifically, we can help in the areas of ECG,
ECG Stress Testing, Patient Monitoring, Image Handling, Data Archiving and SCP ("Standard Communication Protocol" for ECG transmission)
|
|
| Realtime Programming |
| Medical devices often require the reliable acquisition, processing and printing of
data in realtime. Sterling has developed a strong capability in this area both for medical and
non-medical devices.
|
|
| Microsoft Windows / .Net |
Sterling has undertaken a number of
projects on the Windows platform ranging from early native Windows
API implementations (ECG ST
Tracking) through the Visual languages VC++, VB, Visual InterDev
(ACC-NCDR Registry project)
to the .Net technologies.
2 of our current projects are based on .Net -
one involving Web based operation while the other is utilizing
C#.Net and SQL Server 2000 to build a Windows Forms client/server
application for the storage and display of medical data.
In a recent proof-of-concept exercise, we combined
our medical, realtime and .Net expertise to develop a prototype central
station running on .Net to display ECG and
other physiological waveforms and other vital signs data for 8 patients using commercially
available bedside monitors. We were pleased to prove that the .Net
framework with its rapid application development environment, when properly applied, can achieve
reasonable realtime performance. |
QNX |
| QNX is a "stealth"
operating system when it comes to a lot of devices in use today. It is one
of the best selling realtime operating systems (RTOS) and is under the
hood of a surprisingly large number of medical devices. QNX is very
deterministic and reliable - a crucial requirement for mission critical
systems that demand "hard" realtime performance. Sterling has used QNX
versions 2.xx and 4.xx, as well as QNX/Neutrino which has achieved a high level of POSIX
compliance making it operate in many ways like a traditional UNIX. A particularly useful
part of the QNX product suite is the Photon micro-GUI. This GUI is
naturally integrated with the realtime operation of QNX and Sterling has
made extensive use of Photon as the user friendly face in front of the
realtime workhorse in both medical (ECG Stress System) and non-medical (Audrey Internet Appliance)projects. |
