The LED test measures diode polarity. While supporting a wide variety of test and inspection requirements, the machine cannot test for solder workmanship quality. For such inspections, automated ...

Mechanical latching relays incorporate internal locks or gears that hold the relay contacts in place after switching. A ...

If you’ve worked on a project with small LEDs, you know the frustration of determining their polarity. This ingenious LED Probe from [David] packs a lot of useful features into a simple, easy-to ...

Key Takeaways: Rice University researchers have developed reconfigurable carbon nanotube transistors capable of switching between p-type and n-type behaviours. These polarity-configurable thin-film ...

A series of polarity-tunable host materials were developed based on oligocarbazoles and diphenylphosphine oxide, and their polarities can be tuned through increasing distance of acceptor and donor ...
