When you inhale, the air within the N95 is quickly replaced by outside air, which means any high CO2 and humidity levels within the N95 is temporary. You are not breathing in a lungful of 5000 CO2 ppm air. Your lungs usually have a lot more volume than the space within an N95 (does not apply to children and people with lung issues).
The space within a respirator is known as "dead space" and should be minimized. There were a lot of novel ideas for respirators in 2020 that had to learn this the hard way, including some full-face snorkeling masks. Full-face respirators separate out the nose and mouth section for this reason.
Your pictures do not show a 3M 8210 N95 as you claim. They show an earloop KN95 of unknown manufacturer, which makes me doubt how scientifically this test was performed.
1. That's what I thought too, so went to a lot of work to test levels before, during and after breaths. I included results for at the end and beginning of a breath and found that levels JUST BARELY got below the OSHA allowed limit at the end of breathing in.
2. Yes, there is a lot of dead space on normal masks, the that's where the CO2 build up comes from.
3. I have found similar studies, one weirdly also vacuums the air out at the same time, but I'd suggest looking into it if interested and believe what you want. I'm just glad I know finally for myself, thought others might like to know too, and am satisfied :)
Bluetooth (and wifi) aren't turned off at all through the Control Center - they changed the wording to say "disconnected", meaning that your phone only disconnects from known devices. But both are still turned on for other purposes such as CarPlay, Handoff, and Location Services (via wifi). For the purposes of this discussion, they are potentially still transmitting a known identifier.
Apple reconnects to known devices and networks at 5am:
Exactly, that's why counting job postings is a terrible proxy for gauging market conditions. Companies may hire anywhere from 0 to 100s of people through the same JD.
Well, it’s an unwise strategy to use on me if they’re feeling pressed for time. I will get enjoyment from putting my foot down for as long as is needed to reach a resolution.
That’s a 20+ minute decision they just made to try to save a few seconds.
> Is the consumer going to pick a more expensive, ugly, non integrated vehicle for their trip?
The consumer does not care about which car picks them up or what hardware integration it has. The consumer cares about which car is available in their service area, how quickly it will arrive, how much it will cost, how quickly it can get to their destination, and that it will do so safely.
You can accomplish something similar now by using multiple accounts, which Instagram supports on a single device. Although Instagram's algorithm already seems to deprioritize the accounts you are actually following in favor of suggestions and ads.
I wonder how much of this ridiculous car money was previously buy-a-house money. If you don't think you'll ever buy a house, you might as well spend it on a car.
I can forgive the circle screen in a Mini Cooper just because it's a heritage thing. What I don't like is, not having physical controls for heated seats, temperature controls, and heated steering wheels. Mini made all those touch screen, which don't work nice with gloves.
Well, it was a heritage thing. The original remakes with the center speedo and plenty of physical buttons were fun. The digital circle thing is an abomination.
I always wonder if the people designing these things have ever lived in a cold climate. They know about cold in the abstract because they put heated seats in, but have they ever woken up in the morning and gone outside to commute to work in a car that's been sitting at -20 degrees overnight. Interfaces that don't work with gloves or mittens on are the worst.
Which is to say, do they know that touch interfaces are bad and do it anyway because it saves money? Or do they go through life thinking they're actually making a usable product?
"Which is to say, do they know that touch interfaces are bad and do it anyway because it saves money? Or do they go through life thinking they're actually making a usable product?"
It's likely the former. Industrial designers are trained on ergonomics so they know the benefits of physical switches.
However, at least in the case of BMW / Mini, they're forced use touchscreens by their management primarily because:
1. Not only it saves money
2. It also enables subscription models for certain features like heated seats and steering wheel. No heated seats? Just remove the UI buttons.
Unless consumers push back (like VW customers did), they will continue to cut costs.
EVs heat up the interior before you get in (very effectively, since they are usually a heat pump for interior heating/cooling and also for battery temp management). Generally you tap a button in an app on your phone about 10 minutes prior, and by the time you get in the car it's nice and toasty. If you keep your car plugged in at home it doesn't even use any battery to do this. Heated seats is just a luxury feature, not a necessity.
When I was street parking in New England winters I was not exactly an EV target customer. I'm sure that's very nice if you have a driveway and home charging though.
Absolutely heated seats are a luxury feature. That doesn't change the fact that if put heated seats in a car and then have touchscreen only controls, you have created a stupid product that's made to be comfortable in cold temperatures but not usable in cold temperatures.
Of course they should be making cars usable in cold temperatures whether or not it has cold weather luxury features, but the addition on heated seats in a car that you can't operate with gloves on just highlights the stupidity of the screen interfaces.
The manufacturer is considering "what would be nice for a car in cold temperatures" and then skipping over "it would be nice if you could turn the heat or defogger on."
I would have literally bought a mini if not for the daft screen and lack of button. Bought a Smart Fortwo instead, happy camper with all my tactile interfaces.
