Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

The MP3 format is officially free 19.05.2017

The Fraunhofer Institute for Integrated Circuits officially said goodbye to the MP3 codec and file format. Key MP3-related patents expired at the end of April. It is reported by National Public Radio.

MP3 (MPEG-1 Layer III) is a popular codec and audio file format that is widely supported around the world. The vast majority of media player developers (both software and stand-alone devices) include MP3 support in their product.

Different patents related to MP3 were owned by different companies, which gave rise to constant disputes and lawsuits. As a result, some device manufacturers (such as MP3 players) did not pay for an MP3 license at all, while others paid a royalty of several tens of cents per device. Alcatel-Lucent, for example, sued Microsoft for $1,53 billion.

The Fraunhofer Institute for Integrated Circuits said in a statement that the licensing program associated with the MP3 patents has officially ended. According to representatives of the Institute, the future belongs to codecs that compress audio more efficiently, such as AAC or MPEG-H, which is being developed.

Despite National Public Radio's announcement of the "official death" of MP3, in reality, the expiration of patents (and the termination of the licensing program) means that MP3 support can be built into your products without any royalties to the organizations holding the patents.

Recently, another common technology, the Adobe Flash Player, officially became a thing of the past. The product has been repeatedly criticized for a large number of known vulnerabilities in the code, and Adobe at the end of 2015 recognized the victory of HTML5 over Flash.
