A judge in Washington, D.C., ruled Tuesday that Apple infringes on one of medical device maker Masimo’s patents for light-based pulse oximetry sensor functionality and components used in Apple Watch 6 onward. The sensor measures blood oxygen levels.

Next the U.S. International Trade Commission (ITC) will decide whether to ban imports of Apple Watches that include the sensor, Masimo said.

In a statement, Apple disputed the ruling.

A deal between Apple and Rockley Photonics could add new medical sensors to the Apple Watch in 2022. That might include non-invasive monitoring of blood sugar levels, body temperature and blood pressure. It might even add the ability to measure blood-alcohol levels.

The British startup promises to “bring laboratory diagnostics to the wrist.”

Custom health chips could be the next big piece of silicon to come out of Apple’s labs.

Apple reportedly has a team of engineers exploring the creation of a customized processor is optimized to make sense of health information from sensors at a faster rate than the S series processors found in the Apple Watch.

Apple accused of reducing sensor accuracy for Face ID

The Face ID sensor on the new iPhone X may be accurate, but according to a new report it could have been even more so if Apple hadn’t been experiencing production problems with the handset.

With the prospect of losing holiday sales, Apple reportedly “quietly told suppliers” that they could reduce the accuracy of the face-recognition technology used in the new handset in order to make it easier to manufacture.

The next major breakthrough for Apple Watch is currently being tested by none other than Apple CEO and fitness freak Tim Cook.

A new report claims that Cook has been spotted walking around Apple’s corporate headquarters wearing a special Apple Watch attachment that could be a game-changer for people with diabetes.

Apple Watch could lead to 7x increase in wearables market

Apple’s great at hopping into new markets just as they’re set to explode, and it seems that the upcoming Apple Watch is no different.

Despite mixed reports about consumer interest, research firm IHS thinks demand for sensor-equipped wearable tech devices is going to see a major acceleration starting next year — largely thanks to Cupertino. Just how much of an increase are we talking about? Try 7x the size of the existing market by 2019, according to analysts.

“Similar to the iPhone and iPad, IHS expects the Apple Watch will set a de facto standard for sensor specifications in smartwatches,” says Jeremie Bouchaud, director and senior principal analyst, MEMS & Sensors. “Most other wearable [original equipment manufacturers] will follow Apple’s lead in [incorporating multiple sensors into devices] — or will add even more sensors to differentiate.”

Sensor-filled shirt can tell your iPhone how fit you are

The iWatch may be set to mark Apple’s debut into health and fitness tracking, but one company is taking the concept of wearables a step further.

The forthcoming $199 OMsignal shirt promises to be the gym wear of the future — featuring a ton of health sensors sewn into its fabric, which constantly monitor the condition of the wearer. Sensors are capable of tracking heart rate, breathing rate, breathing volume, movement (including steps and cadence), movement intensity, heart rate variability, and calories burned.

“The data is sent via Bluetooth to a specially developed iPhone app, which lets you see all of it in real time,” says Dr. Jesse Slade Shantz, the firm’s Chief Medical Officer. “Your iPhone beams the data up to the cloud, and algorithms we’ve developed then push back various metrics — showing you information about your breathing during workouts, and information like that.”

How Big Are Cellphone Camera Sensors Anyway (And Other Interesting Facts)

Whatever it is you want to know about cellphone camera sensors, you’ll probably find it in DP Review’s absurdly in-depth article on the subject. It details not only the common misconceptions about megapixels, but also many real world differences. And it contains the diagram shown at the top of this post, showing the size differences between the sensors in various phones, measured in pixels.

1080p FaceTime Could Be Coming To The iPhone 5S

While the rear camera in the iPhone continues to improve by leaps and bounds — and we can expect the iPhone 5S to continue that trend — the front FaceTime camera improves at a far more glacial pace. In an age of selfies, the iPhone 5’s front facing camera isn’t that much better at offering the sort of fidelity of resolution necessary to deeply inspect our blackheads and pores than the iPhone 4 was.

That’s probably about to change though. Omnivision — maker of the iPhone 5’s front-facing camera sensor — have just announced the OV2724, which crams a full 1080p sensor (or 2MP, compared to the current camera’s 1.2MP sensor) into a tiny cube small enough to go into the next iPhone. And it even shoots at 60 frames per second and offers some impressive dynamic range to boot.

It’s going into production this summer. With decent yields and some luck, that should make it ready for the iPhone 5S when it lands in fall.

Ricoh GR Compact With Big Ol’ APS-C Sensor

Back in the 1980s and 1990s, all compact cameras looked like the Ricoh GR. they might not have been as sleek-looking, but they had big finger grips, a giant full-frame sensor (35mm) film and a fixed wideangle lens.

Now, proving that large sensors are the new black, the GR is packing a DSLR-sized APS-C sensor into its tiny body.

Why Do Photos Taken With The iPhone 4S Look Like Rubbish On The Retina MacBook Pro?

By

The new Retina MacBook Pro is the most pixel-loaded Apple device yet, with more than five million of the little blighters spread over 220 pixels per inch. That’s a lot of tiny dots, but believe it or not, it only translates to a mere five megapixels. And since the iPhone has had a 5 megapixel camera since 2010, pictures taken on an iPhone 4 or iPhone 4S should be able to take full advantage of the Retina MacBook Pro’s 2880 x 1800 resolution display.

So why is it that photos taken with an iPhone 4 or iPhone 4S look so crappy on a Retina MacBook Pro? That’s what Instapaper developer Marco Arment wants to know, and so do we. We have a theory though.

Nikon’s D800 is the best camera in the world, according to camera and lens rating supremo DxOMark. Or rather, it has the best sensor DxOMark has ever analyzed. With a score of 95, it even beats out its big brother, the Nikon D4. It even has an “unmatched quality-to-price ratio,” being the cheapest of the top eight cameras on DxOMark’s charts.

We suspected as much, but the inquisitive engineers at Chipworks have confirmed that the camera inside the new iPad is indeed the same one found in the iPhone 4. The optics, as we already knew, come from the iPhone 4S’ camera.

Chipworks says that “It is very likely that Apple has recycled the 5MP back illuminated CMOS image sensor from the iPhone 4,” — the Omnivision OV5650.

How Nokia’s Amazing 41-Megapixel Phone Works

BARCELONA, MOBILE WORLD CONGRESS 2012 — Yesterday, Nokia announced its crazy new 41 megapixel camera phone, the PureView 808, and the world chuckled. Just how big is the damn phone, I wondered, when Cult of Mac Deputy Editor John Brownlee woke me up and told me the news. But last night I spoke to a Nokia engineer, and it turns out this camera is pretty smart after all.

First, while the sensor does indeed contain 41 megapixels, it doesn’t snap 41MP photos. Instead, the sea of noisy data collected from those pixels is combined in software to get 5MP photos. Why? It started with the desire to design a better zoom.
