Industrial, medical and military cables demonstrate a small sample of a broad range of cable applications that require passing one or more relevant tests to qualify for usage. Surviving nuclear, biological and chemical (NBC) contamination could arguably be the toughest test. Depending on the application, cables may have to be incredibly rugged, handle high voltages or be small enough to fit through the eye of a needle. Here is an example of a very small medical cable.
MICROMINIATURE ROUND CABLE
Designed for medical applications with critical size and electrical integrity requirements, W. L. Gore & Assoc.’s Microminiature Round Cable provides a very small durable solution. Using the company’s High Strength Toughened Fluoropolymer (HSTF) and low dielectric constant expanded PTFE (ePTFE) material, the medical cable handles device flexure, abrasion during routing or tracking and sterilization without performance degradation. An advanced biocompatible dielectric material, HSTF has increased scrape abrasion-resistance and cut-through resistance, as well as improved pinhole free performance in ultra-thin profiles. Specific medical applications for the cable include electrophysiology products and small diameter flexible endoscopes.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
