About the project
A patient monitoring platform used in high-acuity environments was adapted to run on a cost-optimized hardware design intended for new regional markets.
The work involved porting the existing Linux-based software stack, system components, and UI to the new platform.
Engineering efforts focused on preserving waveform quality, alarm behavior, and interaction patterns consistent with the reference device, while addressing hardware constraints and required remediation for regional compliance.

Client challenges
Porting an ICU-grade monitoring application to a cost-optimized hardware platform introduced limits in processing power, memory bandwidth, display handling, and peripheral behavior. These differences impacted waveform rendering, alarm timing, drivers, and HAL layers, requiring remediation to restore system response to the reference model.
The platform had to remain stable across hardware revisions and support regional regulatory pathways. This required predictable timing, consistent signal processing, and reproducible UI interactions during verification—despite the hardware shift.
The work took place in a highly competitive segment, where cost pressure forced the use of lower-priced components while performance expectations remained unchanged. Delivering full-feature behavior on constrained hardware increased technical complexity and compressed the effective development timeline.

Project results
Full Feature Set Restored
All ICU-grade workflows, waveforms, and alarm behaviors were re-established on the cost-optimized hardware platform.
Platform Remediation
Corrected HW/SW mismatches caused by cost-optimized components, stabilizing drivers, HAL layers, and timing paths to within reference-device tolerances.
Accelerated Delivery
Compressed a multi-year migration effort into a two-year delivery cycle through early prototyping, iterative integration, and joint HW/SW bring-up.
Signal & Alarm Consistency
Waveform rendering, alarm timing, and interaction latency were validated to remain within the operational bounds of the higher-end reference monitor.
Optimized BOM Impact
Software and platform adjustments supported a hardware design that reduced total manufacturing cost by approximately 10% compared to the baseline model.
Value we bring
Industry Standards-Aligned Development
We follow processes aligned with ISO 13485 and IEC 62304 principles, including controlled change management, documented verification steps, and traceable work products. This structure supports deterministic behavior checks, stable regression cycles, and smoother preparation for regulatory compliance.
Hardware-Aware Senior Engineers
Our teams include senior embedded engineers with deep understanding of processors, displays, sensors, power domains, BSPs, and timing-critical paths. This expertise helps identify hardware-induced behavior shifts early, remediate integration issues quickly, and restore system response to expected reference behavior.
Flexible Collaboration Model
We adapt our workflow to the project’s needs. We join onsite technical workshops when alignment is essential and operating remotely when iteration speed matters. This flexibility ensures smooth integration with in-house teams and external vendors, stable backlog execution, and coordinated progress across distributed development streams.
