All about slip rings: How they work and their uses

Rotary Systems has put together a really nice basic primer on slip rings -- electrical collectors that carry a current from a stationary wire into a rotating device. Common uses are for power, proximity switches, strain gauges, video, and Ethernet signal transmission. This introduction also covers how to specify, assembly types, and interface requirements. Rotary Systems also manufactures rotary unions for fluid 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.

Western Digital demonstrates prototype of world's first 1-terabyte SD card

Western Digital Corporation unveiled its SanDisk 1TB (terabyte) SDXC card prototype at the at Photokina 2016 trade fair in Cologne, Germany, in September.

With increasing demand for high-resolution content, such as 4K and 8K, the company keeps pushing the boundaries of technology with solutions that support the exponential growth of data-intensive production demands.

"Sixteen years ago we introduced the first SanDisk 64MB SD card, and today we are enabling capacities of 1TB," said Dinesh Bahal, vice president, product management, Content Solutions Business Unit, Western Digital.

The company introduced a 512-GB card at the same show two years ago.

Higher capacity cards expand the possibilities for professional videographers and photographers, giving them even greater ability to create more of the highest quality content, without the interruption of changing cards.

"Just a few short years ago, the idea of a 1TB capacity point in an SD card seemed so futuristic," said Sam Nicholson, CEO of Stargate Studios and member of the American Society of Cinematographers. "It's amazing that we're now at the point where it's becoming a reality. With the growing demand for applications like VR (virtual reality), we can certainly use 1TB when we're out shooting continuous high-quality video. High-capacity cards allow us to capture more without interruption, streamlining our workflow, and eliminating the worry that we may miss a moment because we have to stop to swap out cards."

Western Digital did not announce pricing or an availability date. The SanDisk 512-GB card can be found on Amazon for less than $350. Cards of the same memory size from other brands can be had for less than $200. The introductory price for the 1-TB card could easily run $500 to $700 or more.
