The MPI people look serious and real - they have patents and build 100 KW+ systems . I suspect that the best way to get their technology is to buy some stuff from them. To replicate it (commercially) you would need to understand the patent situation and be sure you were not infringing. As far as generating the signals goes then it rather depends on you skills and resources. I don't know enough about MPI's signal processing to make an actual recommendation but somethign like this might do: https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/sharc-audio-module.html#eb-overview To use it you need a good understanding of DSP and C programming. Probably access to a tool like MATLAB for signal processing development work. The ultrasonic driver board - if you are feeling bold then look on Ali Baba and Aliexpress - but if you are at "day one with ultrasonics" be prepared to get your fingers burned - once when you buy it and then again when you try and use it. I think you might need to hire someone with experience of high power ultrasonics. But if you want to sell a system to end users like you applications suggest why not plan to buy in the parts from a source like MPI - then you'll have an expert on your side rather than competing. The investment to compete with them on developing making the core ultrasonic components would be large. But developing a system like you washer dryer is bridging a gap between companies like MPI and people who want to wash and dry stuff - there may be a gap there you can fill. Please note: the above free advice should be treated with the usual caution - I know very little about the context of your project.

Designing compact 96 V battery systems isn't only about fitting more power into less space. It's about reducing complexity, improving reliability, and making every cubic centimeter count. Our latest aluminum electrolytic capacitor portfolio helps engineers do exactly that. The new 125 V axial and soldering-star capacitors eliminate the need to connect capacitors in series for many 96 V DC-link designs. The result? Simpler capacitor banks, lower assembly effort, fewer components, and robust performance even under demanding thermal and vibration conditions. Together with the upgraded 63 V series, the portfolio supports applications ranging from micromobility and small xEVs to forklifts, electric boats, industrial electronics, and even humanoid robots.

(Image: pixabay ) Solar projects are spreading across landscapes, and researchers are investigating how wildlife adapts to them. Wildlands Network fitted 75 female pronghorns with GPS collars to understand how they move across areas with solar development. The project started in 2024, when 60 pronghorns near Farmington, New Mexico were fitted with these trackers. Then, the organization added another 15 collars in January 2025. With this study, researchers can track the animals’ movement routes, determining if the San Juan Solar and Storage Project affect their pathways. According to Wildlands Network, the pronghorn in this area traverses a changing landscape. Data from these collars allow researchers to compare movement patterns before and after the construction of solar projects. Researchers hope the findings will help them figure out how renewable-energy development can coexist with wildlife movement. GPS collars are strapped around an animal’s neck. They use a GPS chip to determine their location, a battery that powers the electronics, and a satellite modem, radio, or Bluetooth connection for data transmission. Researchers also position the GPS antenna toward the sky for a clear line-of-sight. These GPS collars aren’t always recording data. Instead, they take location fixes at a certain time, such as once per hour or a few times per day. This helps to extend battery life, making it last longer. In Wildlands Network’s case, each collar collects location data once an hour per day. And by 2025, they have collected over 700,000 locations from pronghorn so far. Collars may also store the data locally and send it later, either through satellite several times a day or a USB when the collar is recovered. Some are built with an automated drop-off mechanism, allowing the collar to be released and picked up without recapturing the animal. Other features like a gyroscope or mortality sensor may be included to understand movement or determine if an animal remained in the same place for a long time. To make the collars last longer, designers may keep electronics asleep between fixes or integrate solar charging or other energy-harvesting features. That’s why wildlife collars can collect data for months or years. With such a large dataset, Wildlands Network can examine how pronghorn movement changes across different seasons. The organization measured home ranges, space-use, and movements of 22 female pronghorns within 100 meters of solar fencing. This includes those using passages between fenced solar arrays. Researchers say that slightly changing the design of solar projects could benefit animals. For example, making the bottom of fences higher could allow pronghorn to crawl under them and use their normal travel paths. Have a story tip?

I can vouch about the thermal dissipation issue. I updated an old laptop with Linux using a USB 3 memory stick. It got rather hot! So essentially USB Drives are faster. Maybe worth looking at USB host drivers combined with wireless. --- The performance gap between USB flash drives and microSD cards comes down to physical space, which dictates the complexity of their internal architecture . While a standard microSD card maxes out around 10–12 MB/s if it uses older Class 10 protocols, premium microSD cards can go faster. However, high-speed USB sticks sustain blistering speeds much more easily due to several structural advantages . [ 1 , 2 , 3 , 4 , 5 ] 1. Multi-Channel Flash Controllers USB Drives: The larger housing allows for complex, multi-channel memory controllers. Similar to a solid-state drive (SSD), these controllers can write data across multiple flash memory chips simultaneously (striping data), multiplying the write speed. [ 1 , 2 , 3 ] microSD Cards: A microSD card contains a single, microscopic controller die squeezed next to the flash storage. It generally operates on a single channel, meaning it must process data sequentially rather than in parallel. [ 1 , 2 ] 2. High-Speed Bus Interfaces USB Protocol: Modern flash drives use the USB 3.0 (or newer) standard , providing a massive interface bandwidth bottleneck of 5 Gbps (~500 MB/s) to 10 Gbps. [ 1 , 2 , 3 , 4 , 5 ] SD Bus Protocol: Standard microSD cards rely on the UHS-I bus interface , which tops out theoretically at 104 MB/s. The cheaper, basic cards max out much lower (around 12.5 MB/s to 25 MB/s) because of hardware limitations. [ 1 , 2 , 3 ] 3. Thermal Dissipation USB Drives: Writing data at 130 MB/s generates substantial heat. The larger plastic or metal body of a USB drive acts as a heatsink to dissipate thermal energy, preventing the drive from thermal throttling. [ 1 , 2 ] microSD Cards: Squeezing heavy data transfers into a tiny fingernail-sized plastic form factor traps heat. Slower speeds prevent the card from melting or corrupting your data.
