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. ... >>

Updated Specification for Lightning Connector 13.06.2014

Apple at the annual WWDC event presented an updated specification for the Lightning connector, which will allow third-party manufacturing companies under the MFi program to produce wired headsets and headphones connected to the Lightning port. Of course, in the nearest plans of Apple's management, it is unlikely that there will be a rejection of the classic audio jack in their mobile devices, however, the described solution will already be able to provide users with not just an alternative, but completely new opportunities and a transition to the next quality level.

Among the main advantages, in addition to the significantly increased bandwidth due to the new connection interface, was the expansion of control functionality, as well as the possibility of additional charging, in which a separately built-in battery in massive on-ear headphones, popular among young people, could transfer charge to the battery of a smartphone with an apple logo.

Instead of the standard 3,5mm jack that is ubiquitous in all mobile electronics today, a Lightning connection will give an edge to third party products and sound quality. The transmission of digital audio content with a sampling frequency of 48 kHz will now become available. One of the reasons potential users might opt for a direct Lightning port connection for iOS mobile devices is the flexibility and depth of control over Apple-branded services like iTunes Radio.

"If your headphones have built-in noise cancellation, you will now be able to launch an app on your iOS mobile device that will interact with your headset and provide you with detailed information about its operation and additional settings," - said one of the authorized representatives of the company Apple.
