Over the past decades, roboticists have introduced a wide range of systems that can move in various complex environments, ...

Invented by Ampex in 1956, helical scan was the only method that was fast enough to record video in real time. Using two-inch tape and running at 15 ips, the going rate for tape recorders of the ...

The analysis definitively reveals a helical magnetic field configuration within the HH 80-81 jet. This result mirrors observations of helical magnetic fields in extragalactic jets, strongly ...

If you want to reach a satellite in geosynchronous orbit it’ll take a little more effort, and this dual-feed helical “ice cream cone” antenna could really help. Until recently, the dream of ...

[Dereksgc] puts that reputation to the test by building a helical WiFi antenna — and if that weren’t enough — he also subjects it to a field test. In a real field, is there any other way?

Using the Australia Telescope Compact Array (ATCA), astronomers have performed high-resolution observations of a nearby ...
