Recon Jet: a competitor to Google Glass

25.05.2013

While many users are looking forward to the release of the commercial version of the Google Glass wearable computer, third-party manufacturers are developing and preparing to release their own solutions that can compete with glasses from the search giant. One such device is the Jet, developed by Recon Instruments.

Despite the sporty appearance, Recon Jet goggles can be useful not only for fans of extreme sports. For example, doctors will be able to use the device during operations to monitor the patient’s health, lumberjacks will receive information about the terrain, the area of ​​​​distribution of forest fires and weather conditions, and training information will be available for athletes.

The device boasts a dual-core processor, an HD camera, a speaker, a microphone, a Wi-Fi wireless module, Bluetooth 4.0, a GPS receiver and ANT + technology, thanks to which the gadget is able to exchange data, for example, with sports equipment. In addition, an impressive set of sensors is installed inside the Recon Jet, including a gyroscope, accelerometer, thermometer, altimeter and magnetometer.

According to the developers, the display in the glasses is located on the right in the peripheral vision area and will not distract the person until he purposefully looks at it. In addition, when the user looks at the Recon Jet's miniature screen, they see it in much the same way as a 14-inch monitor from a distance of 1,5 meters.

Among other things, the gadget can be used to shoot videos and photos with their subsequent publication in social networks, as well as to exchange data with a smartphone. By the way, in the near future the company will release an SDK kit, thanks to which third-party developers will be able to integrate Recon Jet into their applications, and therefore the scope of the glasses may turn out to be much higher.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

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, ... >>

REM sleep warms up the brain and saves from hypothermia 22.09.2022

Researchers at the University of California, Los Angeles have published a paper in The Lancet providing a new explanation for the role of REM sleep in warm-blooded creatures. The authors of the work believe that it was formed in order to warm up the body and maintain its performance in case of danger.

Scientists have noticed that in nature, warm-blooded creatures with lower body temperatures tend to have longer periods of REM sleep. And in humans and other animals with a higher body temperature, the duration of this phase is usually shorter.

Researchers believe that this ratio is not accidental. During the REM phase, the brain becomes very active, resulting in an increased heart rate and fever. Since REM sleep comes after slow sleep, in which all processes slow down, it is needed to avoid hypothermia, scientists say.

REM sleep can be thought of as a thermostatically controlled heating mechanism for the brain, triggered by a drop in temperature associated with decreased metabolism and energy consumption during non-REM sleep.

It is this reason that can lead to seasonal fluctuations in sleep duration. Even animals that do not hibernate sleep longer in the winter. The same applies to humans: in hunter-gatherer communities, people sleep about an hour longer during the winter months.

To test the hypothesis and learn more about imminent sleep, the researchers want to conduct a series of experiments with animals that only sleep on one hemisphere (like dolphins and fur seals). Such animals do not require additional heating, which means that their lack of REM sleep will confirm the hypothesis.
