Electronic designs, such as embedded controller units, analogue sensor interfaces, motor drivers, low power battery applications, display solutions and optoelectronics, are essential for most of our medical device systems.
We love complex challenges where the design space only allows tight packaging and high integration of electronic boards. Hotswap is experienced in using state-of-the-art development tools and we are always focused in finding the best suitable solution while limiting the development, manufacturing and life-cycle cost.
Many products that we work on include means to measure and control things. This inevitably leads to analogue electronic design for measuring signals from sensors and controlling parts such as pumps, valves, and motors. Most designs also include digital electronics, with the rapid decline in cost of microcontrollers; all but the very smallest systems have a CPU to implement the desired behaviour.
All electronic devices need power to operate and we design products that use disposable or rechargeable batteries as well as line voltage power supplies. DC/DC converters are common to create all the needed voltages. EMC and electrical safety are considerations that enter early in the design stage so that problems found in later testing – and costly late design changes – can be minimized.
For medical devices, there are more stringent requirements which influence the choice of components and design. Some projects are primarily a task of finding established off-the-shelf products and using them for a particular application.
Designing, testing, and making production-ready CPU boards for embedded systems are common activities in our projects. At the outset, balancing performance, development time, and production cost are important issues to solve in the early phases of a project. Component development is rapid so a constant eye on the offerings from suppliers is important. The latest hot microcontrollers have packed everything a small embedded device may need into a single chip, graphics, memory, USB, Ethernet and more. The new CPUs available also has the performance which can make embedded software development a whole lot easier as computing power is no longer a bottleneck.
