Zero-IF older than superhet
Zero-IF, also called heterodyne, is older than superheterodyne. See Reginald A. Fessenden's 1916 U.S. Patent 01,172,017 for an example.

Re: Demise
"I do not necessarily understand the point you are making here. Are you saying that changing a radio channel provides a risk? I personally do not see it that way "

Fasmicro, I mentioned about change in attention, while driving. Any other operation while driving can change driving attention.

Re: Madness, not progress
"That seems to be the paradigm as there are radios in most of the smarthphones and they work very well. The challenge for the industry is not the technology, it is just that it is competing with many other choices and alternatives."

Goafrit2, yes you are right. I think in near future TV also may vanishes. Now a days most of the GSM providers are providing IP TVs and internet version of channels.

Re: Demise
"That is not the case in U.S. There are hundreds of stations one can choose in some cities in U.S. The problem I have with radio is the fact that except I am in the car, I do not see any other place I need to listen to it."

Re: Demise
"But that does not change what the consumer hears. The big question is not the underlining technology but the program. I know that without BBC, most parts of Africa will drop their radios. BBC Radio service remains a very important product in radio across Western and Central Africa"

Fasmicro, but that increases the clarify and sound quality.

Re: Software defined Radios
"Practically, every Android phone has FM Radio. Unless there is something I do not know, it works just as the one from the FM frequency. As people buy phones with these capabilities, radio will be like watch - devices that will fizzle one day irrespective of what we may think about them at the moment."

Goafrit2, yes most of the soft radios have only FM stations. I don't know why they hadn't include AM or SW stations.

Re: Madness, not progress
 "There are not a lot of innovations in this space largely because the opportunities are muted. How many college kids are buying radios and how many families have them? These are not things that people spend a lot of time thinking how to redesign and remake. FM, AM, and the whole nexus of radio while important are not within the sights of Silicon Valley geeks."

Goafrit2, only physical radios can be vanished, soft radios can be there by embedding in all music systems including smartphones, tablets etc.

Liquid-based cooling of electronics is rarely the preferred solution to thermal management, but it may be the only one; improvements in the underlying components may make it a more-palatable option.
The basic component values associated with the low-voltage AC charging circuit for the Ring2 video doorbell have me wondering if I am missing some basic understanding.
Medical devices from wearable to big machines embody leading-edge technologies, but they also must meet an enormous menu of safety, power, and EMC standards that have major effects on design innovation, flexibility, and time to market.
