Little Laser Trip Wire circuit presented here can detect movement of people or objects while passing through the laser beam and trigger security alarms as alert signals to those concerned. What is ...

Expensive semiconductor laser diodes have no tolerance for fast voltage or current transients. To minimize the risk of damage, a standard JFET-clamp circuit shorts the laser when there is no supply ...

A carbon dioxide laser writes electronic circuits onto ordinary baking parchment by selectively exposing cellulose fibers ...

Plaintiff SEMICAPS filed suit in the Northern District of California, alleging infringement of U.S. Patent No. 7,623,982, which relates to the testing of electronic circuits using a laser. The ...

The first circuit of ultracold atoms has been unveiled by physicists in the US. The team has already shown how the atomic current in the circuit can be controlled precisely and believes that similar ...

For small volume production, the Fusion3D 1100 system creates three dimensional circuits and laser-structuring of molded interconnect devices. Reportedly, the system is quite compact, making it easy ...

The National Technical University of Athens in Greece has developed a method for potentially ushering in an age of cheaper electronics. The researchers successfully created polymer circuits using ...

Taken from the 2022 Physics World Optics and Photonics Briefing, where it appeared under the headline "Inscribing the way to a brighter future". VitreaLab, a photonics start-up based in Vienna, was ...
