Alcatel OneTouch POP7 and POP8 tablets

12.01.2014

Alcatel has introduced two inexpensive Android tablets - OneTouch POP7 and POP8. These are the first tablets in the "interesting and colorful" series of OneTouch POP mobile devices.

Of the two new products, Alcatel OneTouch POP7 is distinguished by more modest functionality, apparently due to the low price, which has not yet been announced. The tablet is equipped with a 7" TFT touch screen with a resolution of 1024x600 pixels, has a MediaTek MT8312 dual-core processor with a clock speed of 1,3 GHz, 1 GB of RAM, 4 GB of internal flash memory plus a slot for microSD memory cards.

OneTouch POP7 has a 2-megapixel rear camera, a 0,3-megapixel front camera, a Wi-Fi module, a GPS receiver and an infrared sensor (optional). It is also known about the support of 3G networks. The tablet weighs 285g and comes with protective cases in a variety of colors.

The Alcatel OneTouch POP8 specifications include an 8" IPS touchscreen display with a resolution of 1280x800 pixels, a quad-core 8382GHz MT1,3 processor. Just like the first model, OneTouch POP8 is equipped with 2MP and 0,3MP cameras, GB of built-in flash memory, 4 GB of RAM, has a Wi-Fi module, support for satellite GPS navigation and 1G networks, as well as an infrared sensor.The tablet weighs about 3 g, the case thickness is 322 mm.Like the younger model, OneTouch POP7,9 is enclosed in a plastic case, differing, at the same time, with a thinner frame around the screen.

According to Alcatel's plans, the OneTouch POP7 tablet will hit the market at the end of February and the 8-inch OneTouch POP8 will go on sale in March.

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Wireless speaker Samsung Music Frame HW-LS60D 06.05.2024

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Eternal implant the size of a grain of sand 22.08.2016

Despite the fact that recently the ideas of transhumanism are gaining more and more popularity, many people are not yet ready to implant implants in their bodies. However, a recent study from the University of California at Berkeley suggests that the future may be closer than we think.

University engineers have developed a tiny, grain-sized sensory graft that has already been successfully implanted into muscle tissue and peripheral nerves in rats. "Neural dust" allows you to monitor vital signs in real time, and can become a new milestone in implantation and prosthetics technologies. Such systems could help clinicians perform more precise microsurgical procedures and patients better control over prostheses.

The transducer, which is about 3 mm long, contains a piezoelectric crystal that converts ultrasonic vibrations into electricity, which powers the transplant, the researchers said. The sensors are driven by pulses of ultrasound emitted every 100 microseconds, allowing researchers to work in real time. Ultrasound was chosen because it allows working with "extremely small implants", unlike radio waves.

“Before that, specialists had no way to telemetry from inside the human body in this way, because they could not locate something subminiature in the body. But now I can use this tiny sensor to work with organs and even nerves, without much work to get the right data," says Michelle Maharbitz, one of the study's lead authors.

The sensor is coated with a layer of epoxy resin, and scientists hope that a later generation of sensors can exist inside the human body for decades without being degraded or rejected by the body.

"If a patient needs to control a robotic arm with a computer, they can simply implant an electrode into the brain and it will last a lifetime," explains Ryan Neely, a graduate student in the Department of Neuroscience at the University of California at Berkeley.

In the future, the researchers hope to shrink their invention even further. According to the Independent, they want to achieve a size of 50 microns, which will allow it to be used in the brain with almost no restrictions.
