Fiber Optic Rotary Joints Add a Spin to Sensing, Mobile, and Robotic Fiber Systems

To the passing optical signals, fiberoptic rotary joints (FORJs) are nothing more than fiber connectors, which provide connection between one or multiple fibers. Their unrestricted ability to rotate, however, gives them a critical role in many sensing, mobile, and robotic fiber systems such as ROVs (remotely operated vehicles), aerostat radars, submarines, satellite antennae, OCT (optical coherence tomography), mining vehicles, cranes, wind turbines, robotic vehicles, broadcasting (mobile cameras), etc. This article discusses some of the applications where optical rotary joints are indispensable. www.princetel.com

Avoiding Common Mistakes in Extractables/Leachables Program Design

Mistakes in program design for extractables/leachables testing can lead to significant delays, rounds of questions, and the need for additional testing. And, in some cases, all of the extractables/leachables testing may need to be repeated. To avoid these costly mistakes, it is important to understand the current standards as well as the current interpretations and opinions from regulators interpreting these standards. In this whitepaper the experts from WuXi AppTec discuss the current standards, interpretations and will provide you with tips to avoid common mistakes when designing your program.

Bonded Magnets: A Versatile Class of Permanent Magnets

Permanent magnets are ubiquitous in modern societies. Devices which use permanent magnets include motors, sensors, actuators, acoustic transducers, etc. These are used in home appliances, speakers, office automation equipment, aerospace, wind turbine generators, medical laboratory diagnostic test equipment, and more. It is estimated, for example, that a typical automobile uses up to 120 permanent magnets in windshield wipers, starter motors, seat adjusters, door lock actuators, fuel pumps, sensors, gauges, etc. The development of Hybrid Electric Vehicle and Electric Vehicle drive technologies has been greatly enhanced by the availability of high performance magnetic materials.

Heavy Duty Shaft Coupling Strategies

Heavy-duty shaft couplings have traditionally had a couple of defining design characteristics. For one, these couplings usually rely on keyed shaft connections. For another, they tend to be overengineered with regard to stiffness. Keyed connections and excessively rigid coupling designs do have some under-recognized limitations— especially in large industrial, material handling, construction and mining machines.
