Google Glass glasses will transmit sound through the skull bone

07.02.2013

According to the Federal Communications Commission (FCC) documents, the Google Glass wearable computer will not only be equipped with 2.4GHz 802.11 b/g WiFi and Bluetooth 4.0 modules, but will also receive a bone-conducting speaker, thanks to which users will be able to listen to audio without using headphones. The vibrations that will pass into the inner ear through the skull bone will allow a person to hear not only music, but everything that happens around him.

This is stated in the text of the FCC document in the paragraph "Integrated vibrating element that transmits sound to the user by contact with his head." A few days ago, we recall, Google filed a patent application for a mobile computing device with a built-in bone conductive speaker. Note that this technology is not something new, but the use of devices such as Google Glass can significantly increase its popularity.

The prototype of Google Glass glasses was presented to a wide audience six months ago as part of the Google I / O conference. After that, the wearable computer was repeatedly shown to the public and even became a participant in New York Fashion Week in September last year. It is expected that developers will get their hands on the device within the next few months, while for ordinary users the gadget will be available only next year.

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 ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Night light can lead to excess weight 05.12.2022

Turning on the lights at night can affect your meal schedule and add a few inches to your waistline.

According to Ohio State University researcher Laura Fonken, mice that were exposed to low light at night gained 50 percent more weight over an eight-week period than mice that spent their nights in complete darkness.

"In many ways, our society is now running on a 24-hour schedule," Fonken said. These results suggest that such a schedule may affect metabolic function, leading to weight gain.

Hormones that help metabolism affect people exposed to light at night, Fonken said. Night light could reduce the amount of these hormones in mice, and together with a malfunction in the internal clock of mice, could cause them to gain weight.

Mice are nocturnal, so they usually eat at night. But mice living in dim conditions ate 55 percent of their food during the day, compared to mice in standard light-dark conditions, which ate 36 percent of their food during the day. This is evidence that their internal eating schedule has been disrupted due to the change in light, the researchers say.

Mice that were exposed to light at night showed altered feeding behavior, eating more during the resting phase, which may be responsible for the weight gain.
