Wireless headphones working 18 hours without recharging

wireless-headphones-working-18-hours-without-rechargingHeadphones “NU” is another amazing product that I came across when I surf the crowdfunding portal Kickstarter. These wireless headphones may be of interest primarily to fans of unusual gadgets, as well as those who do not want to charge Apple AirPods every 5 hours of music. The development of British engineers from the company’s Third Skin compares favorably with competing solutions.

What is revolutionary about these headphones? First, they are practically invisible when worn on your ears and look at your face in the front. They can be seen only if to look at you in profile. The earphones are attached behind the ear and inside the ear shell has a flexible hose on the end of which is fixed a fancy design. The sound is provided via a unique hybrid speaker, providing a vibration of air, and the ossicles. In this case the speaker is only responsible for the middle and high frequencies, but the bass creates the two piezoelectric elements and transmitted directly through the skull bone.

wireless-headphones-working-18-hours-without-rechargingHeadphones equipped with active noise-cancellation headphones, so that will isolate you from any noise of the outside world. Also, the gadget in embedded sensors to read your temperature, heart rate, and also any sports activity that can replace you fitness tracker. Not without built-in microphone, so you can use “NU” as a headset for chatting with friends on the phone. And infrared sensor will allow you to control the headset with gestures, without touching it. The most pleasing in this case that the headphones mounted two battery capacity 260 mAh, which will ensure their continuous working in the mode of listening to music for up to 18 hours.

If you decide to support the project right now, NU the headset will cost you £ 119. When the device goes on sale in the first quarter of 2018, it will cost 40% more. Developers have managed to collect about 10% of the required amount for 2 days of the campaign. We can only wish them success in achieving this goal.

fujitsu-stylistic-r727Another device is equipped with a USB 3.0 port, a front lens 2 megapixel, wireless adapter Wi-Fi 802.11 ac and connect the keyboard (turning a novelty into a laptop). Also has Bluetooth 4.1, DisplayPort, NFC and the rear camera at 5 MP. The option is available 4G LTE modem. The low speed of mobile Internet will not have to complain.

The body is made of metal alloy and provided with a folding stand. If we talk about the dimensions of the next — 319 x 201 x 9.5 mm. the product Weighs 830 g.

Developed technology that allows a taste of virtual objects

developed-technology-that-allows-a-taste-of-virtual-objectsDespite the rapid development of virtual reality technology, at the moment when immersed in virtual space involving only sight and hearing. Of course, there are various tactile technologies like vibration, force feedback and even such strange and humorous, but it is a workable solution, as Nosulus Rift. But with all this, to a full simulation is still far. On the other hand, perhaps very soon, in a virtual environment you can feel… the taste.

For the development of new technologies is responsible for two independent groups of scientists from the National University of Singapore and from University of Tokyo. Their developments are, if I may say so, to “simulate the taste sensations”.

The first development for the authorship of the Singapore inventors is created in 2013 and includes a special spoon with a grid of tiny electrodes. These electrodes when exposed to the taste buds of the tongue can imitate the bitter, sour and salty tastes. Unfortunately, the authors did not manage to get simulate the sweet taste, but it came from their Japanese colleagues.

The device of Japanese scientists working on the technology of the so-called thermal simulation: the working part of the device consists of tiny solid-state thermoelectric elements (or, if simpler, Peltier elements) that can be heated and cooled with an incredibly high speed. The algorithms of temperature control in such a way that upon contact with the tongue it causes a sensation of sweetness.

Both technologies are designed not only to make virtual reality more realistic, in terms of entertainment content, but also have a lot of applications that can help people. For example, such stimulation can give patients who have lost the ability to taste, to regain that feeling. Or, for example, the gadget may find applications in nutrition, when a person is very difficult to give up favorite foods in favor of useful, but not always delicious food.
