It's worth noting that this isn't new technology. This paper is specifically about how their new technique provides a small but statistically significant improvement on existing te…

If you are an absolute nutcase, you could characterize a set of line stretchers and a multiplexer on a high end VNA then offset the inputs of the 4 channels on that UXR with them, …

Keysight at least, has a fab where they make their own ADCs. Those are something like ENOB 6, 10 bit raw up to 120GHz and are used in their oscilloscopes but can also be purchased …

It's technically not a signal generator but an Arbitrary Waveform Generator. It provides a base-band modulated signal to the signal generator which the sig gen upconverts to the RF…

In the simplest possible terms, EIRP is the equivalent of power density. It takes into account how narrow the beam from your antenna is.

Yotta marketed itself as a "bank" where every time you deposited to savings you would get a free lotto ticket for the month based on how much you deposited. They did this by offeri…

Bosch did release an actuator-based solution. They got sued by SawStop for patent violations and lost and pulled it from the market. SawStop's main patent just covers the concept o…

They offered to relinquish one important patent, but they have a huge portfolio of patents covering blade breaks specifically applied to table saws. If you go look at the actual te…

This is coming out of Australia so it wouldn't be ITAR, but they do have their own export restrictions on this sort of technology.

This is very similar to current military optics. It just uses a GaAs meta-material surface instead of a GaAs microbolometer array. Fundamentally they are both semi-conductor micros…

Not a strictly new technology but an improvement on existing concepts. This is building an artificial non-linear optic using a metamaterial to make it more compact. It works by fre…

Said another way, you're making a filter. Zeroing out FFT bins is a brickwall filter. Brickwall filters have poor frequency and amplitude accuracy if you are trying to preserve the…
