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.

Hermetic Feedthroughs Safeguard Mission-Critical Electronics

Experts specializing in electronics failure analysis can list a host of reasons for various malfunctions, but one of the most common causes is simple moisture. Because water and electronics do not mix well, several strategies exist to protect mission-critical components from moisture and condensation. One of the most successful methods of protecting key components from water hazards involves hermetically sealed electronics cavities—enabled by moisture-blocking component assemblies such as hermetic feedthrough technology.

The Advantages of LWIR SLS Thermal Cameras

A relatively new type of photon detector material for infrared cameras offers a solution for scientists and engineers who need to record fast thermal transients or capture crisp still images of high speed objects or events. This material, called Type II Strained Layer Superlattice, or SLS, can match or exceed most of the performance of analogous detector materials such as indium antimonide (InSb) or mercury cadmium telluride (MCT). This article compares LWIR SLS detectors to MWIR InSb and LWIR MCT detectors, with specific attention to their integration times, temperature ranges, filtering needs, and uniformity.

4 Steps In Selecting Fluid Connectors For Medical Device And Equipment Applications

With so many risks and options for connecting tubing in medical applications, it is important to have a simple and repeatable strategy for selecting the best connector solution. The process requires a thorough analysis of the application in order to ensure connectors will be compatible with the physical, chemical and biological environment, and be easy to use and help prevent misconnections—whether the application involves connecting air lines for a blood pressure cuff, connecting reagent supplies to a blood analyzer or making critical connections between a patient and heart-lung machine.

Force Sensors For Design

IN RECENT YEARS, factors such as consumer demand and a tough economy have pushed OEMs to produce sleeker, smaller, and less costly products than in the past. This forces designers to spec or engineer parts for increasingly tight space requirements. In this difficult situation, even small components such as force sensors can play a surprisingly big role in the development of successful solutions. A patented, thin-film, flexible but accurate force sensor was developed specifically to target industry needs for a low-cost, unobtrusive, force or pressure-measurement solution. The unique technology eliminates many of the challenges plaguing engineers in the design of streamlined products.
