As of February, Apple, Samsung and Fitbit made up 88% of smartwatch unit sales in 2018, the Smartwatch Total Market Report said. However, the gadgets might not work as effectively for people of color or those with tattoos, according to findings published Wednesday by Stat, a health and medicine publication. Users have complained on Fitbit forums and on Reddit about the smartwatches having trouble giving readings on people with darker skin. Fitbit replied in the community forum and said the Charge HR tracks “heart rate on every complexion” and directed users to a support article. “Fitbit takes accuracy very seriously and continuously performs studies to rigorously test the accuracy of our products among diverse groups of users,” a Fitbit spokesperson said in a statement Wednesday.The company said its PurePulse technology performs to industry-standard expectations for optical heart rate on the wrist. The company said it designed its optical system to emit green light at a sufficient strength to effectively penetrate darker skin and its detector is sensitive enough to accurately detect the heart rate signal.Fitbit, Samsung watches, Garmin devices and other wearables use green lights, which are cheaper than infrared lights, to take readings. Stat’s report said that green light has a shorter wavelength and is “more readily absorbed by melanin.” This makes it harder for people with darker skin tones to get accurate readings.  CNET may get a commission from retail offers. Apple told Stat that it also uses green lights to continuously monitor, but uses infrared light to take readings every five minutes. The company’s support page says its watch measures a user’s heart rate using photoplethysmography. PPG is a low-cost optical technique that illuminates the skin and measures changes in light absorption, according to the US Library of Medicine. Apple’s support page says this works because your blood reflects the red light and absorbs the green light. Samsung and Garmin didn’t immediately respond to request for comment.  Tagscenter_img Share your voice Fitbit Versa 2 and Fitbit Premium promise to revamp my… reading • Fitbits might not track your heart rate right if you’re a person of color • Originally published July 24.Update, July 25: Adds comments from Fitbit and more background information on the Apple Watch.

Republicans And Democrats Seek Path To DACA Deal In Coming Weeks

first_img Share Mark Wilson/Getty ImagesPeople who call themselves DREAMers protest in front of the Senate side of the U.S. Capitol to urge Congress in passing a legislative fix for the Deferred Action for Childhood Arrivals (DACA) program, on December 6, 2017, in Washington, D.C.The DREAM Act has failed to pass when Democrats have held complete control of government; when Republicans have held all the cards; and in periods when the two parties have split control of the White House, Senate and House.But lawmakers from both parties hope to secure permanent legal status for people protected by the expiring Deferred Action for Childhood Arrivals , or DACA, program and they are trying to achieve some sort of solution over the next two weeks.DACA is set to expire in early March, but most advocates agree that the upcoming Jan. 19 government funding deadline is likely the best remaining window to cut a deal that grants some sort of permanent protection to the roughly 700,000 DACA enrollees — people in the country illegally who entered the U.S. as children.Whether or not something passes will likely hinge on two key questions: How far Democrats are willing go to force a vote, and whether President Trump will compromise on his demands for a border wall.In order to get a bill on the House and Senate floors, Democrats may have to embrace a position that many party leaders aren’t too comfortable with: brinkmanship over a government shutdown in order to achieve their goal.Democrats opted not to play that card in the days before Christmas, when the last government funding deadline came, went and was solved by a short-term resolution keeping things running through mid-January. That frustrated activist groups like United We Dream, which branded Senate Democrats who voted for the continuing resolution as the “Deportation Caucus.”It’s a criticism President Trump latched onto in recent days, tweeting that “Democrats are doing nothing for DACA — just interested in politics.” He went on to predict that “DACA activists and Hispanics” will start “falling in love with” Trump and the GOP — a prediction that ignores the fact that it was Trump who set the early March expiration date for the program in order to force congressional action. It’s also not clear how Trump could have DACA activists love him while holding onto his base, some of whom burned their “Make America Great Again” hats when Trump broached a possible deal on the program with Democrats last year.Democrats are doing nothing for DACA – just interested in politics. DACA activists and Hispanics will go hard against Dems, will start “falling in love” with Republicans and their President! We are about RESULTS.— Donald J. Trump (@realDonaldTrump) January 2, 2018Since Trump announced in September that the DACA program would be ending, Democrats have repeatedly and loudly called for a fast-tracked vote to make it permanent. “[Republicans] are saying, ‘well, we can wait until March,’” House Minority Leader Nancy Pelosi, D-Calif., said in December. “Well, we can’t. And as I said to them, that is an act of cruelty to say you can wait until March when people are losing their status every day.”But, so far, they haven’t used the leverage Trump handed them in September, when he agreed to a government funding deal that expired at the end of 2017.It’s still not clear whether they’ll use it in January. It’s also not clear what Trump would want to see in a final immigration deal.In early September, it seemed like Trump, Pelosi and Senate Minority Leader Chuck Schumer, D-N.Y., had struck the broad outlines of a deal: trade a permanent DACA fix for increased border security that would not include Trump’s signature campaign promise of a coast-to-coast wall on the southern border with Mexico.But that infuriated immigration hard-liners like Rep. Steve King, R- Iowa. “I know the people that were strong Trump supporters, that were on his bandwagon early on,” King said after the preliminary deal was made public. “They came on board because: build a wall, enforce the border, enforce immigration law, no amnesty ever. And if they see amnesty coming out of the White House, then that’s the one thing that will crack his base.”So Trump quickly backtracked, insisting his wall would have to be part of any deal.About a month later, the White House added to those demands, saying any agreement would also have to include major changes to legal immigration policies as well. Trump wants to swap policies that prioritize family ties, often referred to as “chain migration,” for a system that emphasizes the skills individual immigrants would bring to the country. That’s a shift Democrats say they won’t support.Negotiators have two weeks to figure out a deal — and perhaps just as importantly, Trump has two weeks to figure out what he’ll demand.Copyright 2018 NPR.
