Health care continues to evolve toward self-treatment and away from in-person appointments. In addition to helping reduce physical contact, new technologies have given the general population unprecedented access to health care tools for self-monitoring...
When designing reliable servo drive control modules, both precision and protection are critical for ensuring reliable operation. Underestimating the importance of these features in the design process could...
Remember when science fiction movies would have a scene showing a fully automated factory managed by artificial intelligence? Such factories exist now!
An autonomous factory relies on real-time communication between...
A trend in the rapid growth of smart grids is enabling more intelligent functions in residential equipment, such as smart electricity meters and data concentrators. A smart grid requires a multi-communication...
Internet of Things (IoT) and industrial Internet of Things (IIoT) have become synonymous with connected factories and making traditional factories smarter in order to reap the benefits of greater efficiency....
Sensors measure the processes in factory environments to control the conditions in the overall system through the programmable logic controller (PLC). Typical measurements are temperature, pressure, flow and level. There are different techniques that...
We’ve all experienced the inconvenience of a dead spot. Macro remote radio units (RRUs), also known as macro cells, are typically deployed in a centralized location to cover dense urban areas. As the number of people using RRUs grows beyond capacity,...
Power-factor correction (PFC) and inverters in telecom rectifiers and server power-supply units (PSUs) need to be able to sense the current signal from the high-voltage side for the controller at the low-voltage side. To do so, they use an isolated current...
Man’s best friend may soon be industrial robots.
As robots are becoming more commonplace in factories, it is important that they become more intelligent, autonomous, safer and efficient. All of this is enabled with precise motor control, advanced...
Because of their role in security applications, it’s important that outdoor cameras do not malfunction or fail, regardless of whether they’re placed in tropical or frigid climates, or climates that experience...
It is a familiar scene in labs across the globe: A design engineer is pushing the envelope, seeking to enhance functionality or improve performance. Unfortunately, while digging deep into low-level system timing...
With the rapid growth in demand for delivery services, electric motorcycles (e-motorcycles) are becoming more popular as a transportation method because the battery capacity is much larger than e-bike/e-scooter batteries...
