Mask mandates now in 8 states, federal mask requirements extended

The COVID-19 omicron variant has prompted more indoor mask mandates. President Joe Biden has also extended the federal mask mandate through March 2022.

For the most up-to-date news and information about the coronavirus pandemic, visit the WHO and CDC websites.

With the omicron variant now detected in 39 states in the US, federal mask mandates have been extended until March 18 in an effort to curb the spread, President Joe Biden recently announced. The federal mandate was originally supposed to expire on Jan. 18.

The federal requirement to wear a mask over the nose and mouth applies to people riding the bus, train and airplanes The extension is driven by a concern that the country could soon be fighting two COVID-19 variants at once. The highly contagious delta variant is still circling the country, while the new omicron variant has cases rising rapidly.

Last week, a statewide mask mandate for California was reinstated for indoor public places — effective Wednesday — and will last at least a month. California joins seven other states (Hawaii, Illinois, Nevada, New Mexico, New York, Oregon and Washington) and Puerto Rico in requiring most people to wear masks indoors regardless of vaccination status. Connecticut’s indoor mask mandate only applies to the unvaccinated.

The World Health Organization and the US Centers for Disease Control and Prevention continue to recommend everyone wear a face mask in crowded areas, regardless of vaccination status. While scientists are testing the effects of omicron on existing vaccines, it’s possible for people with breakthrough infections to spread any COVID-19 variant. Although the CDC believes vaccinated people may be contagious for shorter periods of time, they can and do contribute to new cases, especially for people who are asymptomatic and may not be aware they’re infected.

Both the WHO and CDC agree that people who aren’t vaccinated should continue to wear face masks because they account for the majority of COVID-19 cases and deaths around the world. As omicron spans the globe, scientists agree that anyone eligible for a booster shot should get one (here’s how to quickly make an appointment). We continue to update this story as new information comes to light.

Here’s the latest on mask mandates and tighter restrictions

The Biden administration extended its mask mandates for those traveling by trains, buses and airplanes on Dec. 2 due to concerns around the new omicron variant. And while the US has travel bans to prevent the new variant from spreading, omicron has already made its way into at least 39 states.

Other countries have also begun tightening COVID-19 restrictions. For instance, Germany recently announced a lockdown for those who are unvaccinated. Some states in the US have also tightened restrictions, requiring proof of full vaccination to enter businesses.

Which states have mask mandates?

The following states require most people to wear masks while in an indoor public setting.

California
Hawaii
Illinois
Nevada
New Mexico
New York
Oregon
Washington

The territory of Puerto Rico also requires masks for everyone indoors, while Connecticut requires masks indoors only for unvaccinated people.

Why are coronavirus variants like omicron and delta serious?

A new study shows omicron is four times more transmissible than the delta variant, which was considered the most contagious of the variants identified so far, according to the WHO, but omicron tests are still underway and guidance could change. It’s too early to tell how dangerous the omicron variant is at this time, though symptoms so far appear mild. It is understood to have more mutations than the delta variant.

Both variants are spreading among both the vaccinated and unvaccinated population, though hospitalizations, serious illness and death are less likely to occur in those who are fully vaccinated. Dr. Rochelle P. Walensky, director of the CDC, on Friday said nearly 80% of the confirmed omicron cases in the US are fully vaccinated, with about a third also having received a booster.

CDC guidance: Fully vaccinated should continue wearing masks in some areas

The current CDC guidance for mask wearing says that everyone age 2 years and older, vaccinated and unvaccinated, should continue wearing masks indoors when in public places, especially if in a high COVID-19 transmission area, to help prevent spreading the disease to others.

Earlier this year, the guidelines said those who are fully vaccinated can «resume activities without wearing masks or physically distancing» except where required, such as in planes and businesses. But that guidance quickly changed over the summer when it was found the delta variant can cause breakthrough infections in vaccinated people.

What is the WHO’s position on mask wearing?

Wearing a mask consistently continues to be important, even for people who are vaccinated, a WHO official said during a press briefing. «People cannot feel safe just because they had the two doses. They still need to protect themselves.»

Wearing masks in public places is essential to keep people from inhaling particles that will cause them to become sick, Dr. Maria Van Kerkhove, an American infectious disease epidemiologist, said during the same briefing.

While the Pfizer and Moderna vaccines are showing robust protection against variants, breakthrough infections can still occur.

TMR vs. Hall Effect Controllers: Battle of the Magnetic Sensing Tech

The magic of magnets tucked into your joysticks can put an end to drift. But which technology is superior?

Competitive gamers look for every advantage they can get, and that drive has spawned some of the zaniest gaming peripherals under the sun. There are plenty of hardware components that actually offer meaningful edges when implemented properly. Hall effect and TMR (tunnel magnetoresistance or tunneling magnetoresistance) sensors are two such technologies. Hall effect sensors have found their way into a wide variety of devices, including keyboards and gaming controllers, including some of our favorites like the GameSir Super Nova.

More recently, TMR sensors have started to appear in these devices as well. Is it a better technology for gaming? With multiple options vying for your lunch money, it’s worth understanding the differences to decide which is more worthy of living inside your next game controller or keyboard.

How Hall effect joysticks work

We’ve previously broken down the difference between Hall effect tech and traditional potentiometers in controller joysticks, but here’s a quick rundown on how Hall effect sensors work. A Hall effect joystick moves a magnet over a sensor circuit, and the magnetic field affects the circuit’s voltage. The sensor in the circuit measures these voltage shifts and maps them to controller inputs. Element14 has a lovely visual explanation of this effect here.

The advantage this tech has over potentiometer-based joysticks used in controllers for decades is that the magnet and sensor don’t need to make physical contact. There’s no rubbing action to slowly wear away and degrade the sensor. So, in theory, Hall effect joysticks should remain accurate for the long haul.

How TMR joysticks work

While TMR works differently, it’s a similar concept to Hall effect devices. When you move a TMR joystick, it moves a magnet in the vicinity of the sensor. So far, it’s the same, right? Except with TMR, this shifting magnetic field changes the resistance in the sensor instead of the voltage.

There’s a useful demonstration of a sensor in action here. Just like Hall effect joysticks, TMR joysticks don’t rely on physical contact to register inputs and therefore won’t suffer the wear and drift that affects potentiometer-based joysticks.

Which is better, Hall effect or TMR?

There’s no hard and fast answer to which technology is better. After all, the actual implementation of the technology and the hardware it’s built into can be just as important, if not more so. Both technologies can provide accurate sensing, and neither requires physical contact with the sensing chip, so both can be used for precise controls that won’t encounter stick drift. That said, there are some potential advantages to TMR.

According to Coto Technology, who, in fairness, make TMR sensors, they can be more sensitive, allowing for either greater precision or the use of smaller magnets. Since the Hall effect is subtler, it relies on amplification and ultimately requires extra power. While power requirements vary from sensor to sensor, GameSir claims its TMR joysticks use about one-tenth the power of mainstream Hall effect joysticks. Cherry is another brand highlighting the lower power consumption of TMR sensors, albeit in the brand’s keyboard switches.

The greater precision is an opportunity for TMR joysticks to come out ahead, but that will depend more on the controller itself than the technology. Strange response curves, a big dead zone (which shouldn’t be needed), or low polling rates could prevent a perfectly good TMR sensor from beating a comparable Hall effect sensor in a better optimized controller.

The power savings will likely be the advantage most of us really feel. While it won’t matter for wired controllers, power savings can go a long way for wireless ones. Take the Razer Wolverine V3 Pro, for instance, a Hall effect controller offering 20 hours of battery life from a 4.5-watt-hour battery with support for a 1,000Hz polling rate on a wireless connection. Razer also offers the Wolverine V3 Pro 8K PC, a near-identical controller with the same battery offering TMR sensors. They claim the TMR version can go for 36 hours on a charge, though that’s presumably before cranking it up to an 8,000Hz polling rate — something Razer possibly left off the Hall effect model because of power usage.

The disadvantage of the TMR sensor would be its cost, but it appears that it’s negligible when factored into the entire price of a controller. Both versions of the aforementioned Razer controller are $199. Both 8BitDo and GameSir have managed to stick them into reasonably priced controllers like the 8BitDo Ultimate 2, GameSir G7 Pro and GameSir Cyclone 2.

So which wins?

It seems TMR joysticks have all the advantages of Hall effect joysticks and then some, bringing better power efficiency that can help in wireless applications. The one big downside might be price, but from what we’ve seen right now, that doesn’t seem to be much of an issue. You can even find both technologies in controllers that cost less than some potentiometer models, like the Xbox Elite Series 2 controller.

Caveats to consider

For all the hype, neither Hall effect nor TMR joysticks are perfect. One of their key selling points is that they won’t experience stick drift, but there are still elements of the joystick that can wear down. The ring around the joystick can lose its smoothness. The stick material can wear down (ever tried to use a controller with the rubber worn off its joystick? It’s not pleasant). The linkages that hold the joystick upright and the springs that keep it stiff can loosen, degrade and fill with dust. All of these can impact the continued use of the joystick, even if the Hall effect or TMR sensor itself is in perfect operating order.

So you might not get stick drift from a bad sensor, but you could get stick drift from a stick that simply doesn’t return to its original resting position. That’s when having a controller that’s serviceable or has swappable parts, like the PDP Victrix Pro BFG, could matter just as much as having one with Hall effect or TMR joysticks.
