Why do nearly all your pics of early pioneers of the 70's & 80's look like ''here's what this guy will look like 20-30 years'' from his High School grad yearbook. Don't bother answering, I see you're too much a coward to answer comments.
@@rickden8362 The photos are sourced from news articles and papers. He even cites the source when each image is shown. A lot of the publications appear to be from when the people died so that would explain the age. Calling him a coward for not answering comments is not a very good way to get him to answer any FYI.
the fact that RU-vid offers a reaction system, doesn't mean someone has to obligatory participate. and i see you are using the technique of getting negative attention. my experience is though that positive reactions usually work much better.
The great seal actually had 3 components: a resonant cavity, an antenna, and US personnel stupid enough to accept it as a gift and put it in the embassy.
Or they knew exactly what was going on and used it to send misinformation and gain intelligence on who the operators of the microwave illuminator were (which would have had to have been close). The intelligence world is full of double bluffs and moves that look like incompetence can be completely intentional.
When it comes to soviet interaction with the US federal government during FDR, it's never just naive stupidity. There's always some western communist in the background controlling the strings.
Thank you for this video. My father, Alfred Koelle, was the first author of the paper shown in the video at 14:37 and went on to be a co-founder of AmTech, a company described in the video. My dad passed away ~10 years ago, but he would have loved this video.
>It's very important not to lose a bomb or two fun fact: if I had a nickel for every time the US Federal Government "lost" a nuke, I'd have 32 nickels. Six are still missing. Which is not a very fun fact at all, and more of a morbidly fascinating fact.
"I'm not sure what worries more. The fact that we just lost a nuke or the fact that it has happened so often we have an established protocol for it..."
@@ralanham76 I don't have a protocol for what I'll do if my house suddenly explodes. I served 17 years in the army and we didn't have a protocol ALL the food we were provided was suddenly bad. The manual just stipulated that if a food item was bad it was to be replaced with a good one, inventory inspected for further cases and HQ be notified in case it was a wider problem. Nobody considered it plausible that it would ever happen that ALL of it had gone bad. My point is: Protocols are developed when the seemingly unlikely becomes reality. I guarantee you that the first time a nuke was lost everyone went "uh.. NOW what?".
He went though GULAG camps where he was forced to work for the soviets and developed that device. He eventually had miserable life under soviets and died in poverty.
Did you hear the reasons he might have left the USA? 🤦♂️ I'm sure the same happened 2 years ago to thousands of students etc when they became the enemy again . 🤷
@@AnthonyCarroll-ue3uv Neutrality Act of 1937? Invasion of Czechoslovakia? He was a soviet citizen and Soviet spy and was also earning millions of dollars in USA from his work... On Russian wikipedia the reason is very clear: "In 1938, Theremin was summoned to Moscow".
I appreciate not having to rewind your videos because the autoplay preview, that happens when scrolling through videos on the RU-vid app, doesn't play audio, which can result in missing the first few sentences. Thanks for taking your time and not talking right away.
I gotta say while your productions are among the very best RU-vid videos, the RFID story is among the best you have done. I was a teenager in the 70's, and first saw the Knogo tags in Leesburg, Florida at Belk-Lindsey tagging along a clothes shopping trip for my sisters. Of note the tags were installed and removed on clothing items with a machine that released a clip that held a push pin system. . Essentially the memory is that a small burr on the tag's pin had snagged on the garment when the cashier was removing it- damaging the garment and a no sale- happy brother, unhappy sister!. Over the years I have curiously watched the way these tags, very bulky, piled up at the cash registers in boxes and spilled out. Nice of you and your team to give a hard to learn about item and credit to the conceptual process as well as refinement. In the late 80's, I saw the tags on my uncle's dairy farms of 250 cattle. Personal computers even kinda of a new sight in homes, yet my aunt and uncle manage all of the items you mention. Uncles said they mainly compared food intake and milk output. The feeder, read the tag and dispensed varying food to each cow--- my technology awaking #2, #1 was a ATM in 1976 in a Sun bank in Eustis, Florida. As a late adopter, I was still a few years from my first Macintosh. Thanks again for a excellent vignette on RFID. I would like to hear more of the "invasion of Privacy" hurdles you mention about auto tags. Seems unimaginable in todays bio-marker populace.
RFID tags were used in the Netherlands years ago - to track blood bags in hospitals. It allows blood to be delivered to the right operating theatre using the 'just in time' approach (like modern car manufacturing). The system tracks each bag via RFID sensors in the walls to ensure none are wasted. I had a postgrad student who pioneered the methodology for this a couple of deacades ago.
In 1977, a company in Santa Cruz California named "Identronix" made an insertable RFID tag for cattle. This was sponsored by a leather tanning company that wanted to prevent cattle hides from being defaced by branding. This was an "active: chip that used power from the interrogator to activate a microprocessor-based logic circuit to send back a unique code.
Great job. Please cover NFC and SIM/smart cards in a future video. Sadly, for me, Magellan tv shows take forever to impart relevant information. I cancelled my subscription I signed up for years ago. Just very frustrating to pick out small nuggets and have them repeated over and over. The polar opposite of Asianometry, which I love for being concise and pertinent.
Same reason I gave up on the Discovery Channel over a decade ago. That and for some reason, probably to appeal to the people who are already served by every other channel, they turned everything into a soap opera.
Amazon just recently started closing down their grab and go stores (which were apparently powered by oversees offices that had employees manually reviewing everything).
Fascinating about the overseas employees. I always wondered how they were processing it all at sufficient confidence with the AI tech of the time it came out. With humans in the loop the computer processing is probably an order of magnitude cheaper. Quite a "man behind the curtain" situation. I guess it must have been an advertising stunt at least to an extent.
I developed a somewhat similar inductively powered transponder system in the early '70s, receiving US patent 3,898.619 in 1975. The initial application was to automatically locate trains in British Columbia, Canada, without relying on the engineer. A continuously powered 200 kHz " interrogator" was located underneath the locomotive; when it passed over a "responder" buried in the ballast between ties, it powered a unique digital location code to be returned at 27 MHz, which was radioed in to a central office.
Uniqlo did it pretty late, Decathlon a french generalist sports supermarket chain has been doing it for a decade already, labeling all their products with RFID tags which sounded crazy and expensive at the beginning and is just the norm now. Their cashier most often don't scan the items it's auto scanned from the RFID chip
I have a question: If RFID-ish techology was initially rejected for use on toll roads due to "privacy concerns" (to deal with the case of car with no ID detected), how was that issue resolved? I get the feeling that eventually, somebody said "forget privacy concerns" and just started snapping pictures regardless. Certainly, we're doing that now on bridges and toll in California that use Fastrak.
Another tangled tale beautifully told and illustrated. Reminds me of a guy I once met who said he should have invented the microwave oven, given the number of dead pigeons he had seen that had been cooked by his experimental microwave communication antenna at the Royal Radar Establishment. Instead he commercialized the digital correlator.
About a decade ago I started setting off those anti-shoplifting sensors at the door of many stores. Thought I was going nuts until I realized the wallet I had recently purchased had a flat RFID tag still hidden inside one of the credit card slots.
One important part also worth mentioning seems the development of the ISO 14443 type A and B RFID communication standards for 13.56 MHz proximity cards. Type A is based on the MIFARE technology developed by Mikron in Gratkorn, Austria, which was then acquired by Philips (later NXP) in 1995. Type B was a competing/alternative data modulation technology proposed by Siemens (later Infineon). Those are now used ubiquitously in biometric passports, in contactless EMV payment cards and in lots of door access-control systems.
Decathlon have also used those magic checkouts for a while, and I refuse to believe they're anything but magic. Also huh, I didn't know that electronic tolls also used RFID. I had never really wondered how they worked.
Fascinating. I hoped you were going to cover the tiny rfid units used to 'chip' pet animals and also how a full shopping basket is scanned that was shown at the beginning. Maybe a part 2 is required?
Keysight probes with many accessories (>10) come with an RFID tag on the little baggie for each accessory. Presumably they use it to ensure the kit in the box is complete.
In Portugal, the automatic tolls became widely used in 1991, called "Via Verde", so have some doubts if in fact was in the USA, that first became to be used such system. Thanks to a banks integrated system, whereby that time was normal was normal to buy train tickets, concerts tickets or pay electric and water bills on an ATM, rapidly this toll system went to be used on gas stations and parking spots.
Somewhat related to self checkout. Aldi Grocery in the USA uses electronic price tags on the shelves. They appear to use infra red as a communication pathway as I see a small lens on the tag. There is a chance this is just a light sensor that shuts the display off when the lights are out in order to conserve battery. Supposedly Walmart is moving to this technology as well.
We have RFID self checkout at some UK stores : Declathlon being one of them, but you have to put the items in one at a time. The biggest drawback for some stores is RFID is blocked by liquids and metals so a tin of soup might not scan
I worked for a contractor on the EZ-PASS project. The tail around the office was that at one point taking a picture of the occupants of the car was not deemed to be an invasion of privacy until a toll collecting agency sent a picture of the occupants of a supposed violation to the home of the owner of the car. The owner's wife opened the envelop recognized the driver as her husband's secretary and realized they were having an affair (and used that picture as part of the evidence).. After that only the image of the license plate could be saved. ,
I remember square foil antenna stickers in the inside cover of library books as early as 1980's when before PC's became common. They were just a passive square spiral, without any electronic device. My guess has been that that antenna (square spiral) as a slightly different length so had a unique id. Books could be scanned in/out, but believed status was stored in a central computer. These appear to be precursor to RFID. NFC like used on touch-less credit/debit/payment cards appear to be the most advanced device of this type, by including compute and memory storage capability.
Probably a resonance pickup. The spiral antenna was deactivated by a metal foil card slid into the pocket by the librarian at checkout. The metal foil card had the due date printed on the end that stuck out. Another card could be brought in and placed in the book you wanted to steal. Or foil could foil the whole system.
There are some anti-shoplifting tags that are a combination of RF excitation and acoustic emitter. When the modulated RF resonates with the tag they vibrate at a specific ultrasonic frequency which is picked up by microphone. When deactivated a more powerful RF signal burns through a small electrical connection altering the resonance. No chip in the tag. Some library security tags work on a similar system but are somewhat self resetting or can be manually reset.
@@douggolde7582 That’s why the Walmart approach was to tag pallets and cases, rather than individual items. On the other hand, individual items of high value can often justify the cost of a tag. I use a machine that consumes chemicals from $5000 containers, each with a tag. It is deemed worth spending a few cents per container to tag it, although people have still found ways to defeat the system. They always will.
I read 20 years ago, that "soon" the price would drop to 1-2 cents. Just checked, and it seems it is still an order of magnitude higher. Far, far from being cheap enough for retail store use on all items.
I rarely leave comments but this is one of the best channels on RU-vid, that I know about. Thank you so much 🥰 you’re probably gonna be the first patreon I ever support. If that’s a way to contribute. Seriously, I’m a teacher and I love how you explain everything, the subject matter, everything about what you do. Thank you 😇
Made these at micron in the early 90s die then were size of a big pin head, bonded on aluminum wedge bonder after military contracts were drying up. Wedge bonder was used to lay out antenna wire on capton tape
I remember them being used on clothes years ago, or in those bulky plastic boxes with the magnetic lock, but it seems like RFID is a lot more commonplace today than it used to be.
Regarding the humor in the video about cow identification being the one of the first commercial applications of RFID, this type of cow humor was not lost on the founders of AmTech. They knew the tremendous commercial potential of RFID and were themselves amused that their early research was funded in part by the Agriculture Department for application to cattle ranching. One of the first test AmTech tags was placed on a cow that lived outside Santa Fe, NM. The AmTech founders named the cow "Herman" and they would take visitors to the company to see this cow - everyone had a laugh and loved Herman.
Ken Shirriff's "righto" blog just had an interesting post on RFID chips ("decapping" them and digging into their design etc). (ok NFC but pretty similar)
I was at a conveyor belt sushi restaurant in Japan a few years ago, and they used tags in the plates to quickly tally up bills for each person or table. Each dish, which had an individual price, had its own colored plate with, i assume, a unique rfid tag and the waitresses put a scanner up to the sides of the stack of plates and with a beep, got your bill.
Jus knew of that guy who sketched the circuit on a plane while on his way to St Paul. Does anyone have advice on how you can get to that level. Even with the background knowledge, it still looks like a daunting task to be able to apply the knowledge that fast on the fly and have it nearly perfect.
Amazing this technology is so ambient- I never heard anyone around me talk about this ever, and I was only really aware of its existence when I got my first RFID debit card.
Note how Cordulo at @13:00 mark, one of the inventors of the modern RFID, got s crewed and died penniless. Very common in the invention industry. Then people wonder why the brightest minds go into services (doctors, lawyers, Wall Streeters).
Actually there 2 types of FasTrak , the active one with battery but it is sort stupid as it only set to one person per car. The other one is passive one but you can set to 2 or 3 people. I had one of the passive ones break on me so I needed to put it back together so I found that it had chip, antenna, switch with 3 settings to say how many people you have in your car.
HAM radio to passive circuit stickers to track products in logistics & to reduce theft or improve supply chain efficiency & tracking of inventory // amazing // nice video too, as you usually do a nice comprehensive analytical history of science and technology thats fun to listen too & watch, educational, interesting, and a form of edutainment
2:50, not really, if you buy the "dumb RFID" which is just a strip of metallic antenna, it's quite cheap, though the design takes time and is not universal like a barcode.
I have believed for a long time that RFID could solve recycling problems. An RFID tag molded into plastic containers could carry information about the chemical contents of the plastic. The biggest problem with plastics recycling now is that, even though plastics can be easily remelted and recycled, mixing different plastics makes that impossible. So plastics are ground up and mixed together and only go to degraded uses like plastic bags and plastic lumber. RFIDs could allow collection by type, and even return to the maker, as whole bottles or other packages, instead of being ground up. Additionally, the RFID would identify the product on retail shelves and boxes.
So a question. Your early example of throwing clothing into a box and it knows what you've picked. How would a system know if there were more than one of the same item? Seems to me that having every bottle of ranch dressing have a unique rfid tag would be time consuming when inventory comes in. VS ranch dressing has it's own ID and each bottle is thusly id'd the same. How do you convey the qty of rfid tags being read?
You got me. I had to look it up, but those Fastrak "Thingies" appear to actually be called "Tags". I am disappointed, not in Asianometry, but in Fastrak.
The video of someone scanning a bar code with a laser optical reader in the conclusion seems to show a lack of rigour in this production,.What about bank cards, pet chipping and even Apple AirTags?
You should add another section about the massive use of RFID in modern chip and pin bank and credit cards and mobile phones, leading to Apple Pay . Also mass transit systems using RFID, ending up with a smartphone becoming your ticket..
If I used a patent that has just barely expired or is almost close enough to cause a lawsuit I would just say hey here is a reasonable amount of money or do you agree to this amount of the profit? Sign the paperwork saying you give permission and call it done. I just wouldn't risk it and right is right, I'm not a greedy person either so, I have an idea for anti theft, that would absolutely deter thieves while being non confrontational to protect employees, also giving the ability to identify the stolen goods and the person that took them easily without searching anyone or physically touching them either, while not being plainly visible to anyone, if I was a thief knowing that I could be marked and tracked by the item I took guaranteeing my arrest would make me look for another way to get money 🤣 you wouldn't even have to have it on everything just them knowing it PROBABLY is there and there is no way of them knowing would definitely deter most of theives , I wish I could afford to patent a few of my ideas before someone else figures them out and does it instead 😢I have many ideas but there are a few that definitely would be useful but I don't have the money to patent them or build functional prototypes etc 😟 and everyone thinks America is so great, not everyone here has it easy, someone has to be poor for someone else to be rich. I see so many people with great intelligence and abilities never get the chance to use it, I wonder how much we have missed out on just because people never get the ability to make their ideas
7:58 to combat shoplifting, how ironic is it they are having the same problem in certain states at present. And these tags still go off at the gates, Hold on to your receipt
