Sony camera puts the image right in your eyes

24.03.2023

Sony Electronics has announced a new camera for the visually impaired.

Sony Electronics and QD Laser have announced a new joint product - the DSC-HX99RNV kit. It will help visually impaired people to see better through the camera. That is, it will make photography more accessible to them.

The kit includes the DSC-HX99 compact travel camera from Sony and the RETISSA NEOVIEWER viewfinder from QD Laser, which uses the technology of laser image projection onto the retina of the eye. This will allow the user to better see the environment, take photos and record videos.

In the US, the kit will be available for $600 via Sony's website in early summer 2023. The quantity of goods will be limited.

Sony also plans to partner with Japanese and American schools to help people with low vision.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. 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, ... >>

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 ... >>

Self-healing software 08.07.2015

Researchers at the MIT Laboratory for Computing and Artificial Intelligence have developed a system called Code Phage that automatically fixes bugs in open source applications. Code Phage is capable of correcting errors resulting from out-of-bounds parameters, integer overflows, and division by zero, according to a publication by the researchers on the Association for Computing Machinery website.

For the system to work, it is necessary to have two input parameters that are entered into the target application, with the condition that one of the parameters causes the program to fail. Code Phage uses the database to look for a donor application that can process both inputs without crashing. It is assumed that such an application contains some kind of check condition that prevents failure and is not present in the target application. The goal is to move this check from the donor application to the target application that needs to be fixed.

To find the test condition in the donor application and understand how it works, Code Phage runs the donor application first with the "good" parameter, and then with the "failed" parameter (that is, causing the crash in the original program). With each "run" the system builds a chain of logical operations occurring in the program until it finds a branch of these chains - the place where the test condition is located.

Using the results of the analysis (symbolic expressions), the system recreates and integrates a similar check into the original application in the language in which it was written. At the same time, Code Phage works with binary donors, that is, it does not need to know the source code of donor applications, since it analyzes their logic.

In their experiment, the researchers were able to fix bugs in seven popular open source applications using 2-4 donors for each. It took from 2 to 10 minutes to correct each error.

According to the researchers, the advantage of Code Phage is that the system can take programs written in different languages as donors, as long as they work in a similar way. There are millions of applications on the Internet that can be used as donors.
