Bluetooth and NFC together to make the most of the two?

The NFC Forum and the Bluetooth Sig join forces to propose a simplification of the peer to peer data transfer.

To send contacts, short information and links, there are lots of opportunities. Everything from the simple e-mail, up to the NFC by Bluetooth.

In the first case, simply just, since his mobile that supports this type of function, insert the contact card in the mail and send it. The problem, it is that it takes time with two correspondents network coverage and that it draws a little in packages data.

When one is nearby, you can switch the Bluetooth should enable, select the contact card and send it, while in the face, must be an acceptance of the connection, enter a pairing code and validate the transfer. Complicated? Not so much that it's, but it can quickly become tedious if two mobile devices do not speak the same "language" and therefore add additional steps which discourage quickly... To give interested in iron at the stage of good old paper-pencil to share a number.

Otherwise, there is the NFC (Near Field Communication). On paper, it is promising, it is sufficient just to select the contact card, the share via NFC and of "bumper" its mobile with that of its neighbour that sharing operates. In reality, this does not always work very well. If two mobile devices are not identical or use different systems, it resumes again on the problems of compatibility.

To simplify this, the NFC Forum and the Bluetooth Sig, two institutions of many companies for the development of these technologies, will now work together to provide solutions to these problems. Major, in the sense that customers do not use them and thus manufacturers are likely to deadlock on them for not burdening the invoice of the smartphone which is already expensive to produce.

A first solution would be the addition of a new bluetooth profile called Secure Simple Pairing, using the NFC to negotiate security between the two keys. With this new profile SSP, it is sufficient just to approach a pedometer or a helmet for the bluetooth liasion to be effective, a good thing in the end.

One could even imagine the transfer of data such as photos, first initiated in NFC and then passing on the Bluetooth 4.0 which itself uses a high-speed transfer and easy WiFi. Finally, we will wait until this happens, because the promises only bind those who hold.

With Memristor, HP wants to kill the SSD and the RAM to join together them in the same module…

With memristor, HP anticipates the future of memory. An ideal solution with large storage capacity of flash memory and access speed of RAM ...

HP is working with Hynix memory specialist, a new hybrid device called Memristor. If it is not expected before 2013, we learn that it would be as fast as the DRAM and thus more efficient than flash memory. Memristor could therefore eventually sign the end of the SSD or flash memory implemented in mobile devices as we know them today.

Memristor offer because the performance of DRAM with the amount of storage space SSD while allowing energy savings. The SSD-killer would be developed in the laboratories of HP already has at least four years and is not yet fully developed. This alternative to conventional DRAM array is similar to the ReRAM (Resistive or RAM) and may even overshadow the SRAM, the SRAM.

17 memristor seen by electron microscopy ...

In practice, it is to superimpose up to 500 billion "memristor" using micro-layers of conductive films with a thickness of only 5 nm. HP, which is still working its process, consider lifting the veil on this new solution in about a year and a half.

Stanley Williams, an executive at HP, had already suggested that the idea was to design products to replace the SSD and RAM today. That entices our curiosity, even though we will obviously take our troubles patiently to find out more ...

Sony HD camcorder and binocular together

The Sony DEV-3 and DEV-5 are two camcorders that videos in HD-quality recording and can be used as binoculars. Under the hood are two G-lenses from Sony with Exmor R CMOS sensors and BIONZ processors. The ergonomically designed handle is equipped with an elastomer coating what ease should benefit.

With the camcorders enable users with the press of a button and videos in Full HD with stereo sound recording. Also one can use the 3D-capture mode, capture video material that in hindsight can be seen on a 3D television. By the digital zoom when recording in 2D to an increase of more than 10 x, increases the DEV-5 the total magnification range from 0, 9 x up to 20 x. The DEV-3 has no digital zoom function and a maximum magnification of 10 x. Photos can be made with a maximum resolution of 7.1 mega pixel.

Sony has chosen to the top to integrate a rotary knob so that in addition to auto focus also manual focus is available. The electronic autofocus can focus at a distance of approximately 10 millimetres, with 3D-images is this distance 800 mm. Furthermore, the DEV-5 an integrated GPS receiver on board each video image automatically provides a geotag. In addition, the DEV-5 a objectiefkap, a zoekerdop, oogcups, a larger carrying case and a neck strap.

The devices get flow via a rechargeable battery that through a charge to about 3 hours of material on can take. In terms of connections the manufacturer has opted for HDMI and USB. The Sony DEV-3 and DEV-5 have a suggested retail price of respectively 1380 Euro and Euro 1980, from november they would be in the store shelves.
