Nanowatts are -60 dBm or what you would expect to receive on your cellphone when you have decent but not great signal. Many radios operate down to the -110 dBm/MHz PSD or lower ran…

Going to be a bit pedantic here but you absolutely can have 0 Voltage. Voltage is the potential energy created by a difference in charge between 2 points. If you have a mass with s…

You shouldn't remove it because it was a retweet, you should have removed it because it clearly meant the opposite of what you were implying it meant. Plenty often people get lampo…

It's probably the politics that led to the roughly 50% rise in cost of living across the state in the last decade. There is little comfort to be had when you're losing your home an…

Conceptually, pattern matching isn't wrong. It's the implementation, presentation, and gross exaggeration of efficacy that is the real problem. DNA matching is still often pseudosc…

I think you misunderstand. When maintenance is being done on the machine itself, yes you are going to do a lock-out tag-out routine. On the flipside, if you remote push the update …

To touch on this a bit. To be a good controls guy that does PLC programming you need to have some mechanical background to understand the equipment you are controlling, you need to…

I would argue that air gaps are critical in ICS networks and PLCs because it is an extreme safety risk to push a potentially bad update from offsite without clearing the operator. …

Neuralink is certainly on my radar as a company to watch but I thought it was more in an invite only Ph.D heavy theory stage than a hire and build board stage. The idea to use an a…

Can you provide any technical detail about what is unique or novel about what your company does? Neither the wired article nor your company webpage has any useful information on wh…

TI makes some MEMS devices for automotive applications, but I don't know of anything in automotive with the type of complexity involved in a DLP. Their mixed signal integrated cont…

I got a demo of this technology close to about 10 years ago from TI. Their "killer app" in the lab was a pairing of the DLP with their DSPs to track rain while driving and reduce i…

There is also the fact that the renewal vote happens on an election cycle. If the republicans hold the house, the tax cuts will be renewed. If the democrats take control, they will…

I used FEKO for some time and it had the best interface for doing optimization out of the EM solvers in my opinion. The development team out of South Africa was also excellent in t…

Most discussions centered on environmental concerns boil down to accepting a massive quality of life reduction for most of the world's population. It is usually colored by someone …

From a purely signal point of view, if you have a good characterization of the drone sound (your training set) and of the noise, then the appropriate filter would be something alon…

I can personally attest that every place on that list is pretty damn nice except for Grand Rapids which is to damn cold! They all have low cost of living and a solid tech scene as …

Summing multiple measurements will grow the noise at the rate of the sum of the squares (also called the 2 norm) because noise is hopefully uncorrelated. The signal, because it is …

I would say, before you dive into multi-fractal stochastic calculus, maybe take a step back and work on some fundamentals that have been used to solved this problem before. Look up…

I think that malanj's point is that the article is disingenuous because it compares the Green Array chip to an MSP430 product under a set of operational conditions specifically des…

A voltage controlled varactor can be made from 2 non-complimentary mosfets with a common body bias. The differential amplifier can be done with as little as 3 additional fets, but …

I've dealt with it in the state fire code for Massachusetts and Maryland. I believe it is also in the New York and New Jersey code books. I'm unsure of other states but, it is a re…

Fire code requires that fire alarms be networked to alert people in all rooms in the event of a fire. Older un-networked units are grandfathers until you begin replacement. Wifi ne…

Given how undiversified Facebook's revenue is; I wonder if they would have a short violent death or a long drawn out one when market share slips.

A sufficiently large radio system built on Mars or at its solar LaGrange point could provide the shielding effect that is normally the responsibility of the magnetosphere. It was s…
