Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

In a continuing drive to reduce board space, power, and cost, Philips Semiconductors this week unveiled the first multifunction logic device in its PicoGate family. The 74LVC1GX04, designed for ...

Researchers at Manchester University in the UK have used graphene to make a new electrically-controlled switching device that supports both memory and logic functions. The device, which exploits ...

A programmable logic controller (PLC) is actually an “industrial computer” that can work stably in complex environments. It can process switching signals, digital signals, analog signals, etc. from ...

We tend to think that artificial intelligence views everything in a coldly logical, binary way, but by making A.I. a little “fuzzier,” the same system can be used to treat patients with bipolar ...

What you do is sometimes determined by what your neighbors do. Scientists believe that this extends to stomatal behavior. Stomata are pores placed at the plant surface that allow gas exchange with the ...
