Car alarm

Section Security and car alarm. The proposed car alarm device (AC) performs almost all the necessary functions, does not contain scarce parts and can compete with industrial systems. The UAS is powered by the car's on-board network (+12 V), and if it fails, it continues to function normally, since it has an internal source. Each correct connection of the electronic key to socket X1 is accompanied by a short start of the siren and a flashing of the parking lights of the car, as well as an alternate transition of the UAS from the Armed mode to the Disabled mode ... >>

Simple motor soft starter up to 4 kW

Section Electric motors. The device considered in the article allows shockless starting and braking of a three-phase asynchronous electric motor, which increases the service life of the equipment and reduces the load on the power grid. Soft start is achieved by changing the effective value of the voltage on the motor windings with the help of trinistors. Soft starters (hereinafter referred to as soft starters) are widely used in industry, transport, utilities and agriculture. The basis of three-phase. UPP - three pairs of anti-parallel trinistors installed in the breaks of each of the phase wires ... >>

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 end of PANASONIC VCRs 29.03.2003

The world-famous brand, known not least for its video recorders, will gradually abandon the production of the latter in connection with the transition to the production of household models of DVD recorders.

Now Matsushita produces 80000 of these devices monthly. The first step in mastering the market will be to increase this figure to 150000. An additional stimulating fact, apparently, will be the traditionally low cost of Matsushita products compared to competitors' counterparts. However, new product lines will no longer be so cheap, but they will still compare favorably with analogues in the number of functions. In any case, we are promised so. All new VCRs are planned to be produced, as before, under the DIGA brand.

Matsushita also has real concepts in stock, for example, such as the AV server. This device is defined by the developers themselves as a broadband receiver. It connects to the home network and can, for example, set the recording timer of a video recorder based on a signal from the owner's mobile phone. The decision to start mass production of this curious device has not yet been made.
