I heard it doesn't work through bandaids either.

from apple's website:

What else affects your reading?
Many factors can affect the performance of the Apple Watch heart rate sensor. Skin perfusion is one. A fancy way of describing how much blood flows through your skin, skin perfusion varies significantly from person to person and can also be impacted by the environment. If you’re exercising in the cold, for example, the skin perfusion in your wrist may be too low for the heart rate sensor to get a reading.
Motion is another factor that can affect the heart rate sensor. Rhythmic movements, such as running or cycling, give better results compared to irregular movements, like tennis or boxing.
Permanent or temporary changes to your skin, such as some tattoos, can also impact heart rate sensor performance. The ink, pattern, and saturation of some tattoos can block light from the sensor, making it difficult to get reliable readings.
If you’re not able to get a consistent reading because of any of these factors, you can connect your Apple Watch wirelessly to external heart rate monitors such as Bluetooth chest straps.
Heart rate is just one of many factors that Apple Watch uses to measure your activity and exercise. Depending on your workout, it selects the most appropriate inputs for that activity. For example, when you’re running indoors, it also uses the accelerometer. When you’re cycling outdoors, it uses the GPS in your iPhone. And even when you’re not in a dedicated workout, it tracks how much you move each day. So Apple Watch can give you the information — and the motivation — to improve your fitness and your health.

Comment murder mystery analogy with chickens (Score 5, Funny) 157

Imagine a chicken's butt. picture it. Okay hang onto that thought because we'll come back to that later.
There's a house made of rubber with a lot of rooms. While all the guests including the butler are gathered in the living room, the guests hear the sound of the master of the house being murdered in his bedroom which is at the end of a distant series of hallways. They also notice that at that moment the butler is missing, but a moment later he's back. It's too far from the dining room to the bedroom for the Butler to have walked there and walks back, so he's not a suspect. But we have two mysteries
1) how did the butler vanish and re-appear. Very suscipicious. could he teleport?
2) how did they hear the scream of the master in his distant bedroom.

The second fact seems to clear the butler since no one wants to believe in teleportation.

Then they discover the house is U-shaped and there's a secret passage directly connecting the bedroom to the living room. The spooky actions and effects at a distance are explained by a wormhole. Also it's the secret passage way that holds the rubber house in a U-shape.

Now remember that chicken butt? I thought so. See if you can get it out of your mind.

Sorry, but you are wrong and so is the article. The main advantage of an integrated modem is power. The modem is basically a processor and if it's on the SoC it can share the memory bus, which reduces power consumption. It also, means less components and cheaper BoM.

perhaps it makes the phone cheaper (or alternatively more capable and just as expensive), but either way, with fewer discrete components the individual combined component cost remains high. If other makers respond in kind QCOM wins too: by putting the LTE modem in the same die as the cpu, then the royalty qual com gets for the LTE patent applies to now more expensive combined component. Thus their revenues rise.

So, what you're saying is that the patents are creating a distortion in the market that forces suboptimal engineering decisions, in this case integrating parts that would otherwise be cheaper if discrete?

This is reason enough why patents should not exist.

No that's not what I said. In fact this is a great example of the patent system working well. first the patent royalties are what led Qualcom to develop technology and then agree to share it via FRAND. and FRAND lisencing is what allowed a proprietary technology to be incorporated into a standard. Both are great!! finally, when there was a FRAND dispute over what was "reasonable" (the R in FRAND), the IEEE adjudicated. I think they reached the right conclusion but any conclusion would have been a hearing of the parties involved. So this isn't a case you want to dress in the arguments you made.

Comment Stock price impact. (Score 4, Interesting) 27

What is interesting is that some of the recent predictions about QCOM are not accurate. Lately QCOM stock has been heading down under two clouds. The first cloud is that the IEEE council appears to have sided with apple and other handset makers that the value of a FRAND license is not relative to the value of the phone (which has been the case up until now) but relative to value of the component that contains the patent. The rationale is simple: if the same component embodying the same patent could be in a cheap phone then the value should be tied to the common component. The latter is said to be about 1/10th the value of a high end phone. Thus QCOMs business model which includes royalties hit a snag. Thus it becomes vital that the components become expensive (and thus only be suited for expensive phones)---and the way to acheive that is to bundle up features into one uber component. Put the LTE in the processor. This is how they solve their problem.

The second reason the stock was headed down appears like it might be wrong information now. TMSC reported a huge drop in expected orders in the next year. It was known Qualcom was the cause of the reduced orders (well convincingly rumored). And thus it was assumed that qualcom was experience a loss of demand and reducing its TMSC orders. Thus the TMSC loss fed right into a QCOM stock price drop. But now we learn the drop was not QCOM reducing orders because of lack of demand for Qcom products but QCOM switching foundaries.

Since QCOM is switching boundaries so the TMSC part of the stock price drop was mistaken.

Finally, QCOM may be going upscale with a more costly process and going even more upscale by bundling patents into components. SO in one move they fix their business model problem. It makes sense too since broadcom has been targeting the low end SOC and wifi market where they can win on volume. Rather than compete at the low end where Broadcom could put Qcom patents in cheap hardware and pay little on the FRAND costs, QCOM veers luxury where it supports their patent portfolio and maximizes the value of their research. It turns their fabless strategy into an advantage that is harder to steal. smart.

It would not be surprising to learn that Samsung made some concession to win the 14nm business, such as promoting it in a next gen phone. Samsung is very familiar with partnering with their competitors--- see their cozy relationship with mortal enemy apple.

I'm thinking this is a huge deal for QCOM. Or at least a huge deal for their stock.

try to imagine the internet without any reliable search engines and no paywalls. In this model all the information is free and out there and is either completely unusable or impossible to locate and no chance of a concensus on what information is the highest value.

If there is no added value why do people pay then? They could put their work up on Xarchiv or just post it on their own web site or submit it to many other journals. When it comes to other journals the model is either author pays or reader pays. Elsevier is reader pays. so called open content journals are author pays. There's even hybrid journals where if the author doesn't pay the reader must. For most journals there usually is also a page charge to the author no matter what.

Yet this people willingly submit their work to journals of both stripes.

The cost is what prevents a tragedy of the commons. Journals who have good names are desirable to be published in and also desirable to peer review for. This becomes a virtuous circle and tends in the long run to promote the best work worth my time to read. That's what I want. there's too much to read. I want some filter on the process. Some level of curation.

When publishing houses can enforce that with either model then cost of that is negligible compared to the resulting value.
