Comments on the article

This module has two oscillators, whose quasi-resonance frequencies differ by an octave. The oscillator level with the upper frequency is set more, and its aftersound is short. It simulates the sound of impact on plastic. The low-frequency oscillator, which is smaller in level but with more aftersound, determines the tone of the drum sound. The trimmer "cut-off" removes vibrations transmitted through the common mount, and the trimmer "sensitivity" sets the maximum amplitude of the trigger pulse, with the strongest impact on the sensor. Outputs "launch" - for other modules of simulators.

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. ... >>

Robotic London Underground trains 19.10.2014

The metropolitan of the capital of Great Britain is considered to be one of the largest and most complex transport systems in the world. "Underground" has 270 stations on 11 lines, the total length of which is inferior only in this indicator to the subways of Asian cities - Shanghai, Seoul and Beijing.

Mayor of London Boris Johnson presented to the citizens of his city projects of updated underground trains, which, according to technical specifications, do not need a driver and are ready to deliver passengers, relying on their own systems. The concept was created by Priestmangoode and Transport for London.

Autonomous trains in the London Underground are planned to be put into operation by 2022, and they will run on the reconstructed London Underground lines: Piccadilly, Bakerloo, Waterloo and Central.

The presented design project of the robotic train was developed with the aim of making the trip of the citizens and guests of London even faster and more comfortable. The latter should be facilitated by a wider entrance, a rational distribution of space due to changes in the interior of the car, and the presence of a personal air conditioning system.

Despite the fact that the train does not require the presence of a person who would control the correct operation of all systems, at the first stage, the driver located in his control cabin will be responsible for the movement of the train. Nevertheless, the automation in the new train was designed from the outset and will allow in the future to perform absolutely all operations without third-party intervention.

The exterior of the new London Underground trains was created with the borrowing of classic attributes and traditional British style of public transport.

“We have participated in subway modernization projects in many countries around the world, and our specialists are well aware not only of what passengers need, but also of how to simplify the maintenance and operation of underground electric transport as much as possible,” said one of the authors of the project of the future automated train, who should appear in the British underground in eight years.
