Since any controller is only as good as its inputs, sensors continue to play a critical role in advanced control applications. To address increasingly tough system requirements, manufacturers are tackling new designs on multiple fronts. From the semiconductor side, integrated sensors take advantage of the design and manufacturing capabilities in that industry. These sensors combine integrated circuitry with sensing elements to make acceleration, position, angle, speed, and gyroscope measurements, among others.
Semiconductor sensors cannot solve every sensing need so other suppliers approach sensor designs with different advanced technologies. These technologies including Hall effect, inductive, temperature, laser displacement, ultrasonic sensors, and photoelectric detectors to solve a variety of measurement problems. Some of these approaches rely heavily on semiconductor components, but the end solution is typically a complete electronic assembly. Programmable signal conditioner ICs simplify the design of those electronic modules.
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.
