Oops...we dit it again ! The antenna world is all about superlatives....Smallest, Best, Smartest, Sexiest technology. This time we reduced our antenna size by 3dB combining Industrial, Mechanical and RF Engineering. Our new ‘Inception HP5354.A’ was born from needing a lower profile, multiband GNSS patch. It is an industry-first "Patch-within-a-Patch" antenna! This cutting-edge ceramic patch antenna offers L1/L5 dual-band stacked patch performance but with the same footprint as a single patch, a 50% reduction in height and lower weight.

The Case of the Shaky Tank: A Story of Science and Solutions Have you ever seen a seemingly simple task turn into a real head-scratcher? That's exactly what happened to our team at Intellithink Industrial IoT when we encountered a vibration problem in one of the tanks of a client. Imagine this: we have a tank filled with a thick liquid, and we use a special tool to stir it slowly. But instead of a gentle mix, the whole tank started shaking like crazy! This wasn't just an annoyance; it could lead to serious damage to the gears, bearings, structure and even the tank itself. Our investigation uncovered a scientific phenomenon called "stochastic resonance". In simpler terms, the interaction between the stirring tool and the liquid created a kind of noise that amplified existing vibrations in the system, making the whole thing go haywire. The consequences of this could be costly, potentially damaging the entire setup. We couldn't let that happen! So, we brainstormed solutions: Change the stirring tool: Maybe it was worn out or not the right fit for the tank. Adjust the speed: By tweaking the speed of the stirring tool, we might find a "sweet spot" where the vibrations wouldn't be amplified. (change the flow rate) Change the viscosity: If all else fails, we could even try using a different liquid with a different viscosity (thickness) to see if that changes the interaction with the tool. However, the story doesn't end there. We acknowledge that this might require further investigation to fully understand the specific details of this "stochastic resonance" and find the most optimal solution. This is just one example of the exciting and sometimes challenging world of engineering! By combining scientific knowledge with a bit of creative thinking, we can solve even the shakiest of problems. #vibration #resonance #stochasticresonance #IOT #reliability #engineering #maintenance #lifecyclecosts

The Challenges of Deploying Indoor Millimeter-Wave Radar Sensors Despite their compact design and straightforward hardware architecture, indoor millimeter-wave radar sensors pose significant #challenges when it comes to real-world application. The complexity of these radars should not be underestimated simply because of their small size. The difficulties are particularly evident in the following areas: 1. Algorithmic approach: The need for low computational resources is paramount, yet the algorithms must deliver outstanding performance. 2. Hardware costs should be minimized, requiring seamless integration with a cost-effective processor to maintain a balance between real-time operation and accuracy. 3. Practical implementation involves overcoming a multitude of potential issues, such as diverse interferences, blind spots, false #alarms, and oversights. 4. The indoor setting is complex, with targets exhibiting a wide range of characteristics, which demands sophisticated #radar signal processing capabilities. 5. Consistency in hardware quality is essential. Millimeter-wave radars are diminutive, but some manufacturers produce boards with varying performance levels; some exhibit higher signal quality, while others are of inferior quality. Additionally, power noise is a concern. 6. Human presence detection is just one aspect of the functionality. Harmonizing features like #gesture recognition, headcounting, sleep #monitoring, and fall detection into a unified system is a complex task. 7. Attaining specific performance benchmarks and precision data is a formidable challenge. #IoT #iotsolutions #radar #radardetector #radarsensor #radartechnology #sensor

🎉 Exciting news! Our paper, "A Lightweight CNN for Real-Time Pre-Impact Fall Detection," has been accepted to the DATE Conference (Design, Automation and Test in Europe) as a regular paper. 🎉 Falls can have serious consequences, especially for the elderly and workers. Our research focuses on detecting falls in the critical pre-impact phase, allowing safety systems like wearable airbags to activate in time and reduce the severity of the impact. We developed a lightweight CNN capable of real-time fall detection, specifically designed for deployment on resource-constrained devices like the STM32F722 microcontroller. Thank you to the incredible team— Cristian Turetta, Touqeer Ali Muhamed, and Graziano Pravadelli—for their dedication and hard work on this project. This will be my sixth consecutive year publishing at DATE. I'm looking forward to adding another DATE mug to the collection! ☕️ A list of accepted papers is available here: https://lnkd.in/dgqwqX_T #FallDetection #AI #CNN #EmbeddedSystems #IoT #DATE2025 #Research #SafetyTech #HealthcareInnovation #A2Track
