Wireless product hardware
Contributed to electronic product development for a next-generation wireless nurse-call ecosystem and related healthcare electronics.
Wireless electronics
for care environments.
Hardware, microcontroller firmware and validation work for a next-generation wireless nurse-call ecosystem.
01 / OVERVIEW
Care-oriented electronics need attention to physical use, communication behaviour and the details of the device itself.

Simplified conceptual overview of the work, not an implementation schematic.
02 / THE CHALLENGE
Where the engineering
gets interesting.
Wireless nurse-call and sensing products bring together embedded firmware, RF communication, enclosure design and product testing. Hardware and software need to be developed with that shared context.
03 / MY CONTRIBUTION
The work I brought
to the system.
Microcontroller firmware
Developed embedded firmware for ATMEL microcontrollers using Arduino and C / C++, alongside communication and device-integration work.
Radar and RF investigation
Worked with radar / RF communication and fall-detection development, connecting sensor behaviour to embedded product requirements.
Physical validation and production support
Conducted water-ingress testing toward IP67 requirements and supported product testing, documentation and design-for-manufacture work.
PROJECT ARCHIVE / HORIZON ELECTRONICS
From patient controls
to the system test bench.
Original photographs of nurse-call hardware I helped develop at Horizon: patient handsets, PCB assemblies, interface hardware and integration test setups. These show my involvement within the wider engineering team.
Patient handsets
Completed handsets and assembled units.
Handset internal assembly
Keypad assemblies and both sides of the PCB belong to the same patient-handset assembly.
System hardware & integration
Interface hardware, display integration and system test setups.
04 / VALIDATION
Check the behaviour.
My work included hardware debugging, firmware checks and physical testing of the product enclosure. Water-ingress testing formed part of checking the design against IP67 requirements.
- ATMEL firmware development
- Wireless and sensing integration
- Water-ingress and product testing
05 / OUTCOME & REFLECTION
What the work adds up to.
Contributed hardware, firmware and test work to the wireless nurse-call development program. My contribution connected electronic design, embedded behaviour and physical product validation.
The device enclosure and the embedded software are part of the same product. Testing the physical and electronic behaviour together helps reveal problems that are easy to miss when each is treated separately.
