The devices are framed in a plastic case (Fig. 21, a and b), the conclusions are rigid tinned lamellar. Weight - no more than 0,3 g.

For KIPD41A1-M and KIPD41B1-1M LEDs, terminal 1 at the base is broadened.

The red color of the glow of the KIPD41A-M and KIPD41B-M LEDs corresponds to the connection of their output 1 with a positive power wire, and output 2 with a negative one. When the supply voltage is reversed, the color of the glow changes to green.

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 ... >>

Random news from the Archive KnuPath - neuromorphic military processor 10.06.2016 KnuEdge has announced a chip called KnuPath, a custom neuromorphic processor designed for speech recognition and other machine learning applications. The chip is already being produced and even used by the company's customers. The KnuVerse speech recognition software package and its accompanying cloud APIs were also announced, but as it turned out, it has been supplied to the military for five years. Codenamed Hermosa, KnuPath uses LambdaFabric connector technology and can be used in large data centers, for example, because the processor is highly scalable. The LambdaFabric bus allows you to combine up to 512 thousand processors into a single system and has a rack-to-rack latency of around 400 nanoseconds. Each chip has 72MB of high-speed onboard memory, 256 DSP cores, 64 programmable DMA engines, and a built-in 32-port L1 router with a throughput of 1TB/s. The performance of each chip on floating point operations is estimated at 256 Gflops / s. The bandwidth of the RAM subsystem is 3,702 GB / s. KnuPath also has 16 bidirectional I/O channels providing 320 Gb/s throughput per processor. Consumes Hermosa 34 watts, which is about 100 watts in terms of teraflops. In key tests such as FFT, Sparse Matrix-Vector Multiply and k-menas Clustering, the new KnuEdge chip outperforms the best graphics accelerators by 2,7-8,1 times. This is a very significant gap, especially given the relatively low power consumption. This processor promises to make speech recognition technologies even more advanced, especially since they have become much more in demand over the past few years.
