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 ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

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. ... >>

Nokia Lumia 1020 smartphone with 41 MP camera 15.07.2013

Nokia at a special event in New York introduced its new flagship smartphone Lumia 1020, equipped with a 41 megapixel camera. First of all, the novelty will appear in the USA, in the AT&T operator network: pre-orders will start on July 16, and sales will begin ten days later. For a smartphone with a two-year subscription agreement, AT&T will ask for $300. In China and some European countries, the device will go on sale in the current quarter, however, its cost in these regions has not yet been reported.

Detailed specifications of the Nokia Lumia 1020 appeared on the eve of the event and were fully confirmed during the official premiere. It makes no sense to repeat them, so let's dwell on the highlight of the smartphone - the camera.
The main camera of the Nokia Lumia 1020 uses a back-illuminated 1/1,5-inch image sensor, an optical stabilization system, and a Zeiss Tessar lens with a maximum aperture of F/2,2. The minimum focusing distance is 15 cm, the maximum image resolution is 7712 x 5360 dots. The camera is accompanied by two flashes: xenon and LED. The first is intended for use when taking pictures, the second is used when recording video.

The Nokia Pro Camera application allows you to manually adjust the exposure, shutter speed, ISO sensitivity (in the range from 100 to 3200 ISO). At a time, the camera can take two pictures - a resolution of 40 and 5 megapixels. The first can be saved, and the second is well suited for publishing on the Web.
The high resolution of the original image allows you to crop the photo without losing quality, a feature Nokia called "High resolution zoom 3x". That's how Nokia "reinvented zoom".

The main camera of the smartphone allows you to record video resolution Full HD at 30 frames per second, stereo sound and tracking autofocus. In this mode, optical stabilization is supported, if necessary, you can use a 6x zoom.

While the Lumia 1020 is Nokia's newest smartphone, the only significant differences from its predecessors, the Lumia 925 and Lumia 920, are a much improved camera and 2GB of RAM instead of 1GB. Most of the other characteristics of all three smartphones are the same.
