High-temp cabinet cooler keeps incineration process in business

An EXAIR client company handles waste treatment on a large ship by operating an incinerator. The area where the incinerator is located gets very hot (over 120° F). This causes failures in the electronics package used to control the incineration process. Since compressed air is readily available, EXAIR's Model HT4225 Cabinet Cooler System is being used to keep the panel cool. It saved the customer from having to replace their control units due to the hot conditions in the incinerator room. Thermostat control is also available, conserving air and operating only when needed to minimize air consumption.
Learn about EXAIR's huge selection of Cabinet Coolers.


Compact snap-in capacitors for general-purpose applications

Seifert thermoelectric coolers from AutomationDirect

Automation-Direct has added new high-quality and efficient stainless steel Seifert 340 BTU/H thermoelectric coolers with 120-V and 230-V power options. Thermoelectric coolers from Seifert use the Peltier Effect to create a temperature difference between the internal and ambient heat sinks, making internal air cooler while dissipating heat into the external environment. Fans assist the convective heat transfer from the heat sinks, which are optimized for maximum flow.

EMI shielding honeycomb air vent panel design

Learn from the engineering experts at Parker how honeycomb air vent panels are used to help cool electronics with airflow while maintaining electromagnetic interference (EMI) shielding. Topics include: design features, cell size and thickness, platings and coatings, and a stacked design called OMNI CELL construction. These vents can be incorporated into enclosures where EMI radiation and susceptibility is a concern or where heat dissipation is necessary. Lots of good info.

What is 3D-MID? Molded parts with integrated electronics from HARTING

3D-MID (three-dimensional mechatronic integrated devices) technology combines electronic and mechanical functionalities into a single, 3D component. It replaces the traditional printed circuit board and opens up many new opportunities. It takes injection-molded parts and uses laser-direct structuring to etch areas of conductor structures, which are filled with a copper plating process to create very precise electronic circuits. HARTING, the technology's developer, says it's "Like a PCB, but 3D." Tons of possibilities.

Top 5 reasons for solder joint failure

Solder joint reliability is often a pain point in the design of an electronic system. According to Tyler Ferris at ANSYS, a wide variety of factors affect joint reliability, and any one of them can drastically reduce joint lifetime. Properly identifying and mitigating potential causes during the design and manufacturing process can prevent costly and difficult-to-solve problems later in a product lifecycle.

Siri's first head of product design launches AI startup combating misinformation

Siri's first head of product and design, Mads Rydahl, has funneled his extensive knowledge of artificial intelligence (AI) and Large Language Models (LLMs) into a new company called Proemial. The startup, co-founded by serial entrepreneur Geet Khosla and tech veteran Brian Pedersen, aims to tackle the most significant problem of accessing credible knowledge through search engines and AI tools: misinformation. The new company's groundbreaking knowledge platform, called "proem," will answers user questions backed by scientific research papers.

"Today's search and AI-powered tools often hallucinate false information, making it look credible, which only adds rocket fuel to the raging fire of misinformation we face globally in every sector of the media, education, policy, and knowledge economy," says Rydahl, who with Proemial wants to give people access to up-to-date, research-backed knowledge. "Proemial is building a platform that makes it possible, for the first time, for anyone to truly understand cutting-edge scientific research at any level of expertise, and apply the insights in their daily lives -- in the classroom, boardroom, research lab, or newsroom."

The team built a simple, yet powerful, way to get answers to complex, important questions supported by references from the largest repository of scientific research in the world. Scientific knowledge is constantly evolving, and proem will keep users up to date on the latest insights by adding over 410,000 new research papers every month. The platform will be open and free, allowing anyone to dive into specific scientific papers, using LLMs to summarize and explain complex topics in the paper and customize an inspiring feed where users can learn, discuss, and connect with others over new insights and breakthroughs.

Uniquely, proem goes beyond just providing summaries of research papers by allowing users to chat with research papers in conversational, non-technical language, enabling deep dives into research, even for individuals and groups with no science background. The developers say proem adapts to users' language style without sacrificing insight and without resorting to misleading info that plague some AI tools' output.

Public beta just released
Proemial's first beta product -- proem -- was released April 28 to a growing waitlist that includes people from organizations like CERN, Novo Nordisk, Google (Alphabet), Facebook (Meta), MIT, Cornell, and Amazon, whose CTO, Werner Vogels, is an advisor and strong supporter of Proemial's vision.

"One of the hardest issues Amazon engineers have to deal with is understanding which research is most applicable to the problem they are trying to solve," Vogels says. "With their innovative use of cutting-edge AI, conversational design, and a deep understanding of science dissemination, Proemial is creating a product that will help us dig through the mountains of publications. I look forward to supporting them in bringing this to life, and I, for one, plan to become a user of their application."

A small group of the company's advisors and invited users have been testing the product for some time, reporting impressive results. One advisor called co-founder and CEO of Proemial, Geet Khosla, to share her experience:

"One of her family members was recently diagnosed with diabetes and prescribed a drug. When she researched this drug using Google and AI tools like ChatGPT, she got general, unreferenced answers or blue links filled with ads," Khosla recalls. "Using proem, she got a meta-analysis conducted on 10,000 people comparing this specific drug to a few other options. For the first time in her life, she could easily understand the research papers referenced and ask further questions to the specific paper, which helped her realize that a different drug might perform better. She sent the paper to the family doctor, who hadn't seen this fairly new research. Her family member is now on a different, better-suited drug."

The diabetes example underscores the value of what happens when people discover, understand, connect, and apply the vast deep knowledge present in scientific papers, says Khosla. "We envision an exciting future, where the knowledge in research papers is actionable for everyone to apply, ushering in a future of continued progress. The solutions to some of our biggest problems are being solved in research papers that nobody reads -- until now."
