When water drops hit the humidity sensors E1 and E2, the resistance between the plates changes, which leads to the start of the generator assembled on the DD1 chip. The signal from the generator is fed to a transistor switch that controls the wiper motor.

The frequency of the windscreen wipers depends on the humidity of the windshield of the car, the more intense the rain, the less resistance between the sensors and the greater the frequency of the pulses generated by the generator.
The humidity sensor is two aluminum foil plates glued to the glass so that the windshield wipers wipe the water between them. Resistors R1 and R2 can be used to regulate the intensity of the windshield wipers. The dimensions and distance between the plates are selected experimentally.

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 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. ... >>
| Random news from the Archive eMMC flash modules
24.02.2015
Samsung has announced the release of embedded drives based on eMMC 5.1 flash memory. The manufacturer emphasizes that the specification was adopted quite recently, and he already has the first products in the industry that meet its requirements.
The line includes models with a capacity of 16, 32 and 64 GB. The drive of the maximum volume in sequential read mode shows speeds up to 250 MB / s, in sequential write mode - up to 125 MB / s. Performance values for random access operations reach 11 IOPS in the case of reading and 000 IOPS in the case of writing.
For comparison, we can recall the performance of 5.0 GB eMCC 64 modules released by Samsung in November 2012. Sequential read and write speeds are 260 and 50 MB/s, and random read and write performance is 5000 and 2000 IOPS. Progress, as they say, is visible to the naked eye.
Compliance with the eMMC 5.1 specification means support for command queuing, a feature first introduced in the eMMC standard, which is useful for multitasking and playing Ultra HD video. In addition, the modules support the Secure Write Protection feature, which restricts access to eMMC protected areas.
