As factory automation systems become more intelligent they will move data acquisition, storage and processing out to the edge of the network, enabling real-time machine controls and management. Factories will be smarter and more connected. These “edge nodes” will predict, then prevent failures before they occur...

Stepper motors are mostly driven in open loop mode. Timing of the step pulses is defined by the controller, the motor is supposed to follow without loosing synchronism. Stepper motors are in fact natural positioning devices which do not require position feedback. The drawback of their design are important iron losses when...

The fundamental process for making a tire hasn’t changed much in 50 years. The compounds, components, and automation used in executing the process have evolved; but the basic process of wrapping piles of rubber together and putting them in a press to get the finished product remains the same. Machine safety equipment,...

In the early 90’s, it was suggested that Charge Coupled Devices (CCDs) were in the process of becoming extinct and considered to be ‘technological dinosaurs’. The prediction is not entirely wrong, if the announcement made by Sony in 2015 is taken as an example.
Sony Corporation has officially announced...

When designing links, SI engineers often begin with a specific connector platform and then modify system variables such as trace length, dielectric materials, and equalization settings to achieve acceptable performance.
This paper takes a different approach by setting various system and equalizer parameters to slightly...

Lithium-ion batteries, like other battery types, are subject to a process of wear and tear during charging and discharging due to chemical changes.
Without battery balancing, the weakest cell in a multicell battery always determines the capacity of the entire system. However, since individual cells age differently,...
