Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

New controller for flyback converters 24.07.2008

STM has announced a new controller for high quality high power flyback converters that can operate in two modes: fixed frequency or quasi-resonant mode. At low load in both modes, the chip enters a controlled burst-mode state with a low frequency (several hundred Hertz) and a constant maximum current.

This is done in order to minimize the overall power requirements, in accordance with the world's energy-saving recommendations. Small controller current consumption (less than 3mA), built-in non-dissipative trigger circuit, are STM developments that improve chip utilization efficiency. The chip is available in two versions L6566A and L6566B.

The first is specially designed for converters operating through a power corrector. L6566A is able to interact with the corrector, turning it off at low load or short circuits. The L6566B is designed for applications where a power corrector is not used and the chip additionally contains a frequency modulation generator at the input. This provides reduced EMI emission, which reduces the size and cost of the linear filter in fixed frequency mode.

Built-in input and output protection includes overvoltage protection, overcurrent protection, overtemperature protection and undervoltage protection. The L6566 multi-mode controller can be used in AC/DC flyback converters, TV and LCD monitors, DVD players, chargers, set-top boxes and other consumer devices.
