Programming


Your product probably needs a bit of a brain, right? That's where we come in. Whether it's a smart control system, a unique way to talk to other devices, or a fancy user interface, we can build the software to make it happen. We use the latest tech, like microcontrollers and FPGAs, to bring your ideas to life.




RF


We've been working with high-frequency electronics and RF/microwave technology for a long time. We've made all the mistakes, so you don't have to. We know the ins and outs of high-frequency design, and we can help you avoid costly pitfalls. What's that worth to you?

Mechanics


Most products need some kind of mechanical parts, right? Think metal cases, plastic covers, and small details like heat sinks. We can design these parts for you and give you the drawings to send to your manufacturer. Or, if you prefer, we can handle the whole process from start to finish, so you get the finished product without the hassle. No need to hunt around for different factories – we'll take care of it all.

What have we done?


Believe it or not, we have a ton of projects. But showing them all would overload this page, so we picked a few highlights.

Tag reader system


To enhance both security and operational efficiency of its trains, Arlanda Express has implemented a tag reader system developed by us. The previous system, utilizing mechanical square locks, was susceptible to weather conditions and required regular maintenance. Our new system eliminates the need for ongoing maintenance while offering substantially enhanced security

Electromechanical train brake


The world of train braking is being revolutionized by the introduction of advanced electromechanical systems, replacing outdated air brake technology. These innovative systems provide a range of benefits, such as quicker response times, enhanced precision, and simplified maintenance.

Speed limiter for train


The train speed limiter provides a calmer and safer working environment for train drivers. By automating speed control, train drivers have more time to focus on what truly matters: monitoring traffic and ensuring a safe journey for passengers.

Vibration sensor for train tracks


To enhance safety and efficiency in railway operations, we have developed a system for our client that continuously monitors the condition of the railway tracks. By analyzing data from sensors, potential problems can be detected before they lead to service interruptions.
