Development Capabilities

Usability and Interface Design

Minnetronix has a dedicated usability group that is experienced and trained in formal usability and human factors design, particularly for complex medical devices with software-based user interfaces. The Minnetronix User-Centered Design process incorporates FDA and international standards recognized best practices (including IEC 62366:2007 Medical Devices – Application of Usability Engineering to Medical Devices). Our process encompasses user research, formative testing and conceptual design, detailed specification and final design, and usability verification and validation, including summative testing.

Safety-Critical Software

Minnetronix has special technology expertise in embedded, safety-critical medical software and real-time operating systems. We deliver products that span platforms and systems, with particular skills in Linux, QNX, Windows, and other real-time operating systems. Our systems are designed to exceed each product’s requirements and include special consideration for life-sustaining applications. Our development approach is tailored to meet the safety classification of your device as well as your company’s goals.

Design for Miniaturization and Low Cost

Minnetronix has a wide range of experience in designing medical devices of various sizes, from small to large. We have developed small, sleek hand-held products, key fob-sized devices, and implantable controllers as well as larger console-based systems.

With Minnetronix' design and manufacturing in one location, we leverage our manufacturing expertise early in the development process to help drive down unit cost. Choosing the right components, assembly techniques, and test methodologies early in the design process, we maximize cost savings throughout the process and better prepare for future scale-up. Our mechanical and electrical engineers utilize MCAD and ECAD modeling packages, providing seamless integration between the two functions, which allows the designers to collaboratively integrate and optimize volumetric efficiency within a device.

Alphanumeric and Graphical Displays and Touch Screens

From hand-held instruments to cart-based systems, Minnetronix designs user interfaces that work for you. We have extensive experience with off-the-shelf and custom displays and touch screens from prototypes through formal product development. Each user interface is designed and tested with end users during the development process and optimized based on specific business goals.

Wireless and Wired Communication

Minnetronix’ expertise covers wide-ranging communication protocols from simple RS232 to Ethernet and Bluetooth to multiband-cellular. For custom protocol or standards compliant communications, systems are designed to fit power, data-rate, data management and location requirements.

Our capabilities include both MICS and proprietary communication schemes. Minnetronix’ systems integration and connectivity experience can provide additional levels of functionality, including device fleet data monitoring, and customizable web portals for remote device communications.

Design for Manufacturability, Test and Reliability

Minnetronix has both design and manufacturing on one campus. This co-location, combined with a Projects Manufacturing Engineering department dedicated to integrating DFM/DFT into the development cycle, means that our engineering teams have the expertise, resources, facilities, access, and long-term orientation toward production to ensure that the devices we develop will be manufacturable and testable.

Minnetronix features a flexible development process that allows you to choose your desired level of verification testing. Our Quality Assurance team is able to determine statistically-based sample sizes, generate and execute test protocols, and coordinate and manage third-party testing houses for requisite certifications.

Rapid Realization of Concepts

Minnetronix’ hands-on engineers and technicians have the tools they need to rapidly turn concepts into functional prototypes. By combining mechanical, electrical, and usability engineering capabilities with multiple engineering labs, a prototyping machine shop, and fused deposition modeling (FDM) 3D printing capability in-house, we are able to conceive and model concept devices quickly and efficiently.
