Submission + - More wearables to be replaced by contact less sensing 2
n01 writes: Last week's story reported on some MIT research for measuring breathing and heart rate from a distance. While that approach required custom built radar hardware, there's now a software-only solution for smartphones that uses sonar instead of radar. The iPhone app (a sleep cycle alarm clock) is not sensitive enough to detect breathing or even heartbeat, but it works remarkably well to detect when the user is moving in its vicinity, the advantage being that it works with the iPhone's built-in audio hardware. The app continuously analyzes non-linear changes in the acoustic room-transfer-function (sampled at ultrasonic frequencies) to detect motion. The user's motion during the night is detected acoustically (instead of mechanically, like the previously existing apps or wearables), so there is no need to wear a device or to place the iPhone inside the bed, it all works from your bedside table.

I bought and tested the app last night. It woke me up at 7:47 when I turned around (had set the alarm time window between 7:30 and 8:00).
Nice app!
Nice app!

Comment Is anybody else heavily reminded of Scala? (Score 1) 636
I didn't have much time to look at the language guide, but in the short time I already discovered many things that exist in Scala, and even the syntax is very similar:
* Tuples
* Closures
* Swift seems to be a functional programming language, even more than Objective-C (the 'functions'/closures there are called blocks).
* For comprehensions
* var/val is named var/let here

Comment Question to experts in quantum physics (Score 1) 108
Does the following make any sense?
My thinking was that if two far-away detectors measure an entangled pair of photons (e.g.), each detector will measure both possible results (e.g. up *and* down). Each detector and thereby their environment becomes entangled with that photon. So each detector and it's environment starts a new branch in their respective many-worlds reality. (One side of the branch for “up” and one branch for “down”).
When you later compare the measurements of the detectors, you will find the measurements pair up (for example they are opposite). In the classical interpretation this could be thought of as a “spooky action at a distance” (instantaneous synchronization). But in the many-worlds interpretation only the worlds where the two separate measurements pair up would survive (the worlds where there is no match would cease to exist, as you put it). This would require no instantaneous synchronization, but would appear as such at the moment when the station that is comparing the measurements is becoming entangled with both detectors, e.g. by receiving the measurement outcome information from both detectors. The four “realities” (e.g up-up, up-down, down-up, down-down) meeting at that moment would be reduced to two “realities”, by merging pairs of “compatible realities” (only up-down and down-up “survive”).
INAQP (I’m not a quantum physicist) so I hope all of this makes sense. And I guess I haven’t added much to the parent’s point except adding a (hopefully valid) example.
If any expert reads this, I would love to know where I can read more about these ideas. There would certainly be a term for this already.
I only wonder why this possibility isn’t discussed more often, I seems such an easy way out of the paradox.

Submission + - Smartphones given new capabilities by novel use of sensors
n01 writes: The advent of mass-produced highly capable smart phones and tablet computers has started to transform economies world wide. Many tools that previously required specialized hardware can now be virtualized by software running on such a device. Through clever programming, the available sensors can be put to novel use that most probably wasn't foreseen in the original design process of the computing device. Take, for example, the app Acoustic Ruler that uses the propagation of sound waves to measure distances of up to 25 meters. Or take an app such as Cardiograph that equips your smart phone to measure your heart rate. While one app uses the audio playback and recording capabilities of the iPhone to measure distances, the other uses the smart phone's camera to sense your heart beat by the variation of light that passes through your finger. What once required the physical production and delivery of a traditional cardiograph or yardstick can now be reproduced and distributed digitally.

You can also use the device in a single device mode (with headphones), as shown in the second video. I just thought that the dual device mode would be more interesting and therefore emphasized it in my submission.

Nobody in their right mind would buy two iOS devices just to use this app. But somebody who's got two of them already might consider buying this app for under a dollar. (Just one purchase required if you have both devices on the same iTunes account.)

Please watch the second video, it shows how the app can be used with just one iOS device and headphones.
I agree that by having the clocks exactly synchronized this could be a lot easier. (But even 1 ms of deviation means an uncertainty of around 34cm.) The challenge was to do it without having the devices synced by an external source (it works on iPod touch devices and iPad as well) and without using a communication channel other than sound.
