IoT is arriving
23
May
If we have 7 billion people in the world, of which nearly 5 billion are
connected, the number of devices is 50 billion and the connection between devices may be even more surprising change that has happened to the internet.
The protocols until recently were reduced, now new patterns begin to emerge beyond the known BlueTooth, arrives with force now ZBee or ZigBee.
The BlueTooth also evolved into the BlueTooth Low-Energy (BLE) or Smart Bluetooth, as old and known protocol for the Internet of things remains strong, since energy consumption is a significant item for the adoption of IoT technologies.
But ZigBee is growing in number of applications and devices, and start earning much interest in developers used in automation of homes, buildings and industrial areas, use an IEEE 802.15.4 standard protocol that is an industry standard wireless technology that operates to applications in the 2.4 GHz range require little data exchange and operate a range of 100 m, so excellent for homes, buildings and industrial.
An evolution of ZBee is the standard RF4CE which has some advantages for complex systems with low power consumption, high security, robustness and high scalability with the addition of nodes and can be inserted into wireless sensor control networks for M2M applications (Machine to Machine) in the IoT.
The latest version is ZBee 3.0, which unifies all ZigBee standards into a single standard.
There are other standards will comment in the next posts.
Sensor artificial tact

Among the various wearable technology (announced with the next ‘wave’), 
is the interesting work on an “artificial” feel, published in the jornal Science.
Second Zhenan Bao the researcher, flexible type of sensor produces a pulse pattern which is immediately recognized by the nervous system, while initially placed hand, this feature enables be used in other parts of the body.
The researcher said: “With plastic materials, we and other researchers in this area had already succeeded in producing touch-sensitive sensors – but the electrical signal coming out of these sensors was not the right format to be interpreted by the brain”.
Other models of computer processing needed to produce the sensation of “touch”, as this produces the pulses directly.
The use of plastic makes the flexible material, and the sensors can be useful in other wearable technology equipment, as stated, “The sensors are very thin and flexible, and are also elastic Then you could mount a sensor on your skin and use. it does to detect vital signs such as heart rate and blood pressure. ”
Just below this layer of “skin” for a printed electronic circuit that functions as an oscillator, which transforms the varying current in a series of impulses. With more pressure and more current, the rate of pulses rises.

Lançado a um ano, o papel Digital Sony (Digital paper Sony) já está sofrendo 
redução de custos e melhorando tamanho e formatos dos seus novos “papéis digitais”.
O papel digital vem sofrendo um crescimento robusto nas vendas, segundo o blog do editor Michael Kozlowski do Good E Reader, e o preço do DPT-S1 já caiu de U$ 999 para $ 799, e a intenção original que era se estabelecer numa faixa de leitores específicos, que querem ler o PDF e não consumidor da Amazon e da Kobo, por exemplo.
O Livro Digital Sony está experimentando vendas robustas para profissionais da indústria que exigem uma tela de e-paper grande. A fim de ampliar seu alcance e escopo, a Sony acaba de anunciar uma redução de preço no DPT-S1 a partir de $ 999 para $ 799.
O preço caiu logo de início com o crescimento das vendas, lançado a U$ 1200 para o ensino superior, advogados e também entretenimento, logo começou um serviço de vendas online e o preço começou a despencar.
Com o preço agora também consumidores de nível médio, o material de plástico flexível baseado em OLED (que é a tela “orgânica” flexivel), apesar de seu tamanho de 13,3 polegadas (quase um formato A4), ele pesa menos que um Kindle DX de 9″ ou 7”. O DPT-S1 tem tela de 13,3 polegadas, resolução de 1200×1600 pixels, armazenamento de 4 GB, com externo de micro SD até 74 GB, conectividade b/g/n e bateria Li-ion comduração de até 3 semanas e peso de 376 g.

Is it possible to compete with the big brands and create thousands of 
small business smartphones in the world? it seems so, is proposing the Shenzhen Zuoer Technology, which promises to help customers who want to build their brands around the world.
The customer chooses from a list of options like a menu from a pizzeria, and may enter the cellular industry for only $ 1,000, even without prior experience, the ultimate goal is to create a brand of smartphones with standard components to a price can reach $ per unit, incredible but true.
Accept applications by a minimum order of 50 units, Zuoer ride your own external plastic housing with LCD screens, circuit boards and batteries from other manufacturers. So any customer, anywhere in the world can compete with Samsung in the international mobile market of $ 410 billion in less than six weeks.

Dec
The invention comes from the University of Bristol, 
England, where through micro-speakers can touch and feel the images projected in 3D, as news in Daily Mail.
The technique is being called tactile holograms, and the effect is produced by the strong changes in the molecules that make up the air using small speakers that produce ultrasound, the virtual objects created by holograms, sensations in the hands in three dimensions.
The next necessary step now is that the technology integrates conventional holograms production technologies, giving the impression that he can play the virtual object, for example, transmitted video calls from a person, it would be possible to greet her.
The great application thought initially is in medicine, where holographic images of tumors could be played by doctors, helping the most accurate understanding of the size of the affected area, assisting the diagnosis and treatment of cancer.

Current technology allows hard drives of up to 3 Terabytes (3000 Gigabytes), but the technology developed
by the Japanese Hitachi now promises an HD 24 Terabytes.
The development made together with NEDO (New Energy and Industrial Technology Development Organization), the technology has developed a breakthrough in miniaturization and organization more productively magnetic grains that make up the HD disks, reaching a size of 10 nanometers (1 billionth of centimeter).
Thereby increasing the density of an HD 8, which now rotates around 500 Gbits per square inch, thus reaching near Gbit 4000, which is a significant increase for a single disk.
Western Digital has launched the new 10TB hard drive in September, the same Helioseal using technology that debuted with the first 6TB WD hard drive in November 2013
Seagate announced a HD 8TB in July.
