Plug-in Replacement APDs Dramatically Boost the Performance of Optical Systems

On the off chance you were wondering, the city of Sheffield in England boasts two main seats of learning: Sheffield University (a.k.a. the University of Sheffield) and Sheffield Hallam University. The latter was formerly known as Sheffield Polytechnic. This was deep in the mists of time when I wore a younger man’s clothes and studied for my degree at that august establishment.

Powering the Ambient IoT with Over-the-Air Wireless Power Networks

The older I get, the more I recall how new technologies made their way onto the market and into the collective consciousness when I wore a younger man’s clothes. Paradoxically, it also seems that the older I get, the more I forget, but since I don’t remember what I’ve forgotten, this really doesn’t prey, play, or weigh on my mind.

Back in the 1950s germanium-transistor era, radio hobbyists could connect two crystal radios to one antenna. The first radio was tuned to the strongest station, and its output was used to power a one-transistor amplifier. The second radio was tuned to a weak station, and the transistor would amplify the ...

Yea, well the idea of my dishwasher (or my wood stove!), not being able to be used until I get a software update (or pay a mandatory subscription fee), doesn’t thrill me as much as you’d think it would. Thanks to the standard amoral silicon valley ethics, and ...

"If we were talking about a real AI system then the system is motivated." There are stories about a Gen AI that was fed misleading data, indicating that one of its creators was having an affair, embezzling money, or something similar. It was then led to believe that this creator ...

If we were talking about a real AI system then the system is motivated. This means it knows about its own survival ie needs and emotional states. It is generally regarded that this is main cause of AI's running amok. Because we (Humans and AIs) compete for the same (or ...

Allen B. Dumont introduced oscilloscopes mid 1930s. Radio development did not need oscilloscopes. Television development needed oscilloscopes. Signal generators existed from the beginning of radio. Galvanometers are even older.

My apology for posting the same comment twice. I was trying to perserve breaks between paragraphs.

https://en.wikipedia.org/wiki/Allen_B._DuMont#Cathode-ray_tube_and_oscillograph states that DuMont started marketing recurrent-sweep oscilloscopes in 1934. Tektronix offered their first triggered-sweep oscilloscope in 1947. Radio development did not need oscilloscopes, as signals could be listened to. Television development needed recurrent-sweep oscilloscopes to observe video and sweep waveforms. ...
