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.

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.

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.

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.

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.

2Pi Optics has begun commercial-ization of the first fisheye camera based on the company's proprietary metalens technology -- a breakthrough for electronics design engineers and product managers striving to miniaturize the tiny digital cameras used in advanced driver-assistance systems (ADAS), AR/VR, UAVs, robotics, and other industrial applications. This camera can operate at different wavelengths -- from visible, to near IR, to longer IR -- and is claimed to "outperform conventional refractive, wide-FOV optics in all areas: size, weight, performance, and cost."

International automotive supplier Continental will launch production this month of short-range radar sensors for advanced driver assistance systems at its plant in Seguin, Texas.
Continental has experienced rapid growth in the business with sensor technologies like camera, lidar, and radar. Since production began in 1999, Continental has turned out more than 10 million sensors, 4.5 million last year alone.
Continental's Rear Cross Traffic Alert (RCTA) system can help to avoid accidents with crossing vehicles when reversing out of a parking space.
Next year should see the 26-million mark, some 10 million of which will be radar sensors (short- and long-range radars). However, cameras -- mono, stereo, and camera systems for 360-degree surround detection -- are also booming. Lane Departure Warning, Intelligent Headlamp Control, plus such functions as Traffic Sign Recognition and camera-based parking assistant systems are becoming increasingly popular in all classes of cars.
A single line will handle production initially, but additional lines are in preparation to satisfy the demand of OEMs manufacturing in the United States. "We plan to produce some 3 million short-range radar sensors in Seguin in 2016," says Karlheinz Haupt, head of the Advanced Driver Assistance Systems (ADAS) business unit of Continental's Chassis & Safety Division. "The numbers say something about how rapidly demand is rising for short-range radar functions like Blind Spot Detection or parking assistant systems. Legislation is a driving force but also our customers' desire for increased safety and comfort is providing a major impetus."
Short-range radar sensors by Continental are indispensable to Blind Spot Detection (BSD) and Rear Cross Traffic Alert (RCTA). The BSD feature warns drivers of cars lurking in the blind spot, making passing and lane changes safer and more manageable, both in city traffic and in highway driving. The RCTA feature detects crossing traffic behind the vehicle while the car is backing out, helping to avoid accidents that can often result in serious injuries.
The Blind Spot Detection (BSD) function warns the driver when there are vehicles in the blind spot of the side-view mirror.
Advanced driver assistance systems represent a key technology on the road to accident-free driving (Vision Zero). Vision Zero will become reality in three steps, beginning with no fatal accidents, followed by no injuries and, ultimately, no accidents at all. "Advanced driver assistance systems and proven sensor technology are a major component of automated driving. Highly or fully automated driving can only become a reality through high-performance sensors and a reliable, accurate model of the vehicle surrounding," says Haupt. From a technological perspective, automated driving is a further development in driver assistance system technology that Continental has already started to pursue.
