Using your smartphone to unlock the door is just one of those good news many people have been waiting for. Technology is already accompanying us everywhere, so why not let it unlock our doors? The Lockitron technology promises to make our daily lives easier by taking advantage of new smartphone technologies. No longer having to go through the stress of forgetting where you left you keys, this technology can help anyone find the way back home. The NFC (Near Field Communication) technology allows you to control systems that monitor the doors equipped with this type of lock. And that's not all. You can even grant access to your home or even office to friends and family. The system unlocks the door from up to fifteen feet away. Temporary access can be granted to other smartphones – for example, allow your party guest to open the door for one night only or let the plumber get inside to fix your leaks when you are not home. So, do you like this wonder of modern technology or you prefer the old school way? Watch the video below to see how the system works.

I wholeheartedly endorse the iPhone 4 as a lightweight, always-on-hand P&S digital camera alternative. But this might be taking things a bit too far. For a mere $190 from Photojojo you can get this iPhone 4 case featuring an adapter allowing you to use either Nikon or Canon lenses with your smartphone. On one hand you no longer have to rely on an app to fake a shallow DOF in your photos, but on the other, look at what you've done to your sleek, svelte phone!
I'm desperately looking for any sign that this is a leftover April Fool's Day prank, but from what I can tell, it's 100% real. And, 100% ridiculous. The removable aluminum case even includes a loophole on either end allowing you to attach a camera strap and hang this Frankenstein of photography around your neck like an actual DSLR. Just remember that autofocus is out of the question, and the tiny sensor on the iPhone 4 is not going to perform anywhere near as well as the one in even the lowest-end DSLR.
*Update: Photojojo has updated the product page with new pricing info. The iPhone 4 version of the SLR Lens Mount is actually $249, while the iPhone 3 version is $149. And we're not sure why there's such a huge price discrepancy.
Even with hundreds of colors and styles, it's hard to find a truly original case for your iPhone 4. But this one from Korean company Connect design changes all that. Instead of covering your device [...]
Now you can check your blood pressure using your iPhone or iPad with two products that make it easy — download an app onto your iOS device, put on a blood pressure cuff, tap the touchscreen, and soon you have a blood pressure reading that you can track every day. They're quick and reasonably priced, but are they accurate?
For my tests, I pitted the iHealth BP3 for iPod Touch, iPhone and iPad against the Withings Blood Pressure Monitor, which also works with the iPod Touch, iPhone and iPad. Our family doctor's been taking blood pressure readings for 30 years, so I figured he'd be a good one to give me his opinion about these devices. So I took both units to his office and comparing their readings with that of an old-fashioned manual blood pressure cuff in his skilled hands.
iHealth BP3
Like a conventional BP cuff, it's secured to the arm with Velcro.
With an iPad 2
In addition to the iPhone app, there's a free iPad app available.
Rear View
iPad and iPad 2 both fit.

iHealth BP3
It's a charging station.
Rear View
That's a USB connector to charge the dock and your iOS device, too

There's the port for the air hose.
iHealth iPhone app
Clean interface, great graphing features, and you can share your results on Twitter and Facebook, as well as email.
This $99.95 iHealth BP3 blood pressure monitor also functions as a charging dock. I tested it with an iPad, iPad 2 and an iPhone 4, all of which fit easily into this attractive desktop unit. You plug the air hose into the side of the dock, and the other end is permanently attached to the blood pressure cuff.
The doctor showed me the proper way to use a blood pressure cuff, placing it about an inch above the elbow, and after touching the start button, the iHealth was doing its work, making a subdued whirring sound. Take a look at the video below that compares the two test units, and you'll get an idea of how they work — they feel just like any other blood pressure cuff, and for this iHealth unit, the whole process took only 31 seconds for each test.
The free iHealth app looks great on the iPad and iPhone. It displays systolic and diastolic blood pressure readings as well as pulse rate. I especially like its graphing feature, which works in both portrait and landscape mode, showing you the history of blood pressure readings over time. I also like the way it can share blood pressure readings via email, but I'm not sure I'd want to opt for its other capabilities: sharing on Facebook or Twitter.
After two tests on each arm (with a bit of waiting in between for blood vessels to go back to their normal state), the blood pressure readings were all in the same range of around 120/80. While none of the readings were exactly alike, all were within the margin of error of the traditional blood pressure cuff used by the doctor.
The doctor says: "iHealth is accurate," and he especially liked the way the dock held the iPhone at an easily viewed angle. He also liked the iHealth's blood pressure cuff, commenting that he thought it was more comfortable than the other one we tested from Withings. Here's a video of both units in action:
An added advantage of the iHealth BP3 is its ability to function as a dock even when you're not using it to measure blood pressure. Plug its included cable into the AC adapter included with iOS devices, and you have yourself a sleek-looking charging station. The dock itself also needs to be charged, so it can perform its blood pressure measurement duties without the necessity of being near a power outlet. The upside of that? It runs on its own power, and doesn't use power from the iPhone or iPad. (The Withings unit also runs on battery power, not draining any power from the iPad or iPhone, either.) The makers of iHealth say it'll run for 100 tests on a charge. Neat.
Withings Blood Pressure Monitor
It's secured to the arm with Velcro.
Other Side
The self-contained unit has a battery compartment inside, with 4 AAA batteries that power the cuff's compressor.

Plug in the dock connector, and it's ready to go.

Withings iPhone App
Here's the readout after a test. I like the way you can combine blood pressure readings with weight and body fat measurements from the Withings Wi-Fi scale
This $129 Withings Blood Pressure Monitor is a self-contained unit, connected via the universal dock connector that plugs into an iPhone, iPad or iPod Touch. Its blood pressure cuff is more rigid, making it slightly less comfortable than the iHealth, but a little easier to manage when you're placing it on your arm.
When you first connect the unit to your iOS device, you're prompted to download the free Withings app. Because I already use a Withings Wi-Fi scale, I already had the app on my iPhone and iPad, and I immediately realized the advantage Withings has here: On a single graph, you can see daily measurements of your weight and body fat percentage delivered by Wi-Fi, along with your blood pressure readings from this blood pressure device. You can email all that data to your doctor or caretaker, too. This e-medicine routine gives you an idea of what the remote health care of the future might be like.
As I did with the iHealth BP3, my doctor and I performed three separate blood pressure readings on each arm (each test taking 35 seconds to complete, 4 seconds slower than the iHealth), and compared those to the readings taken by the doctor using the traditional blood pressure cuff. All the readings from the Withings unit were within the same range as the conventional blood pressure cuff and the iHealth BP3.
The doctor says: "It's equally accurate," but he thought the Withings self-contained blood pressure cuff was bulkier and less comfortable than the iHealth's, and noticed that the way the connector plugged into the iPhone and iPad (without that dock used in the iHealth) made the screen less convenient to operate and view.
As you saw in the video above, the Withings system offers its results on a nicely designed app that shows the systolic and diastolic blood pressure readings as well as heart rate. The Withings app also allows its readings to be shared on Facebook and Twitter, and has the added advantage of connecting with Microsoft HealthVault and GoogleHealth, allowing you to keep all of your health records in one place.
Which is best? Both units are easy to use, accurate, and work well. If you don't already have a charging dock for your iPad or iPhone, the iHealth would be a more practical choice, and at $99.95, it's a better overall value. If you already have a Withings Wi-Fi scale, you might want to choose the Withings blood pressure monitor (even though it costs $29.05 more than the iHealth BP3), so you can coordinate your weight and body fat measurements with your blood pressure readings and see them all on one graph together.
Best of all, neither of these units require a stethoscope and medical training to use and are reasonably priced (especially if you already have an iPhone, iPad or iPod Touch), giving you daily readings of your blood pressure that might make you aware of a previously unknown condition, and perhaps even save your life.
