An obvious flaw is that if a bulb burns out it will show the wrong pattern. It's definitely obsolete technology. They were getting phased out or falling into disuse already in the 90s.

My parents’ church had these lights to discreetly alert doctors who were on‐call. There was a row of I think five bulbs, each a different colour. With no blinking allowed, thirty‐one codes are possible.

They used to say the samething about laptops on airplanes in the 90's. I'm pretty sure I read some posts in the Aeronautical Insanity thread indicating that the interference is real. Maybe it was only in particular circumstances that nobody really cares about though, I forget.

Humphreys posted:I can't believe that sort of talk for some reason. Isn't part of the FCC testing meant to determine if a radio source can interfere with other equipment? Sure, but plenty of radio sources can and do interfere with other equipment. It depends on the license what's allowed or not. *Unlicensed* devices aren't allowed to interfere with other equipment, and if other equipment interferes with them the users of those unlicensed devices are SOL. A licensed device is allowed to radiate per its license, and if it causes interference with an unlicensed device (like most of the stuff in a hospital, all its computers and diagnostic machines etc), that interference is allowed, so the hospital's going to want to tell people "Don't bring things in here that cause interference." Given the ubiquity of cellphones, people who are designing mission-critical stuff like flight control systems or hospital EKGs, now try to design them so cell phone interference won't be a problem, because you can't rely on peoples' willful compliance with such requests to prevent crashing the plane/killing the patient. So it's not an issue. Hospitals' concerns about cellphones are currently more related to HIPAA fears, or the plain old fear that someone will capture malfeasance/mispractice with their camera. I got bitched out by a nurse for snapping a picture of my mother's vital signs on the monitor by her bed. Which I can sort of understand, given the stupidity of HIPAA.

If there was any truth to it in even a slightly dangerous way, do you think that they would even let you take a phone in to a hospital or airplane? They used to say the samething about laptops on airplanes in the 90's. Cell phones and other carryon electronics can absolutely cause interference with airplane equipment and medical equipment. Here's the dirty secret: Know what else causes interference with airplane equipment? The other airplane equipment. You've got a dozen different boxes from multiple manufacturers all flying through the sky inside a good approximation of a Faraday cage, they're going to crosstalk. So you design your box to work properly in that environment. You do sanity checks on your inputs, you write software that discriminates properly. It's not too hard to distinguish between "noise" and "valid input" unless the noise is coming from a jamming pod on an EF-111 or something (Obsolete tech callout. Still can't believe the USAF doesn't operate its own dedicated EW aircraft, but anyway). Imagined posted:Someone told me that the real reason they try to get people to turn off their devices during takeoff and landing is to get people to maybe possibly pay attention to the safety stuff during takeoff and landing, when they're giving the safety briefing and when problems are most likely to happen. Except that they don't care if you're heads-down in a book, or listening to a portable CD player, etc. They only told you to turn off cellphones and the like, or put them in airplane mode. If "they want you to pay attention" was the reason, the restriction would be far broader. Flight attendants don't care if you pay attention to the briefings anyway. The real reason for turning off cellphones, back in the day, was the nature of the cellular network. When you're on the ground and moving at 60mph, you have line of sight to only a couple towers at the same time and handoff isn't an issue. If you're a few thousand feet up at 500 knots you have LOS to a lot of towers, you're reserving a lot more channels and the handoff is much more of a problem. Again, back the in day: I expect current cell towers have discrimination built in to reject connections like that. Phanatic has a new favorite as of 17:05 on May 18, 2016 |

This reminds me of the setup my middle/high school had, where they used colored signal lights to time the classes rather than bells, or clocks in the classrooms. The white light was lit for something like the first two-thirds of the period, then green for the last third, then amber for one minute as a signal to wrap things up, then red while people went to their next class, then blinking red for the last minute before the next class started. The idea was to cut down on getting distracted by the clock, which it did pretty well, though in boring classes people tended to start chanting "aaam-berrr" under their breath towards the end. They gave up on it a few years after I graduated—it dated back to at least the mid-'60s so god knows how much of a pain it was to keep running, particularly if it was a custom build.

I actually had a regional flight in Norway in 2000-2001 where when they started up the plane the pilot got on the intercom and told us that someone had forgotten to turn off their mobile phone and asked us to check them again. That was with a twin prop 30ish seater plane, probably a Dash-8 or similar.

More often than not, such announcements are a ploy to get those last few passengers to turn off their phones. There’s always some who think the rules are beneath them. It’s a shrewd move as a precautionary measure.

I have heard that the main reason why they ask you to turn your phone off is because the pilots can sometimes hear signals through the radios on their headsets and it's very annoying and distracting. If you've ever put a phone by a speaker and had a message come through you know what I'm talking about. That seems pretty reasonable (if it's true, of course).

The same goes for being on set and you're hooked into a radio headset. Even if someone's phone is on silent you'll hear the interference over the radio. Also a similar thing for radio mics having to be at a legal frequency as they got sick of people picking into police channels.

Related to paging in hospitals, I walk past the access panels for the pneumatic message tubes at my job every day. There's probably miles of them running through the walls and floors that'll never be used again but aren't worth removing unless there is a major renovation.

You paid for this education, use the time wisely. It's not high school. I was on a campus that spread more than 6 miles with many programs having to spread the breadth of it in a 15 minute interval. Nevermind that the first and last 5 minutes of a 50+ minute lecture should be summarizing the main points anyway, not introducing new information. Not understanding that schedules exist and presentation skills should be kept up does sound like all the best of academia though.

Then you put that in another sealed capsule shaped for the pneumatic system. Then you put that in the tube. It should be fine.

XYZ posted:Quite a few hospitals still use tube systems for delivering samples and drugs. The last time I was at the Doctor-Plex, I got my prescription from a "vending machine" in the waiting room. I asked how it worked. They take the doctor's scrip (that he creates on a tablet) and fire it to their on-site pharmacist. They approve it (checking against interactions/dosage/allergies) and prints a barcode. You take the barcode to the machine and it scans it. Then a big honking robot fills a bottle (liquid/tablets/capsules), labels it, caps and fires it across the campus in a pneumatic tube. You pay for your co-pay with cash or debit/credit card. It then spits out the bottle and prints a receipt and drug fact-sheets. All said and done, from the time you scan the barcode to getting your meds is about 30 to 45 seconds. The longest part of the process is getting the pharmacist approval (that took about 5 minutes).
