Why do dogs wag their tail or tuck it in?

Under the tail of the dog is a special gland responsible for the individual smell. When meeting dogs, they sniff each other there and remember the smells. Dogs wag their tail when they want to "introduce themselves", show their disposition and spread the scent as much as possible. And when frightened, on the contrary, they tighten their tail.

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. ... >>

MSP430FR5969 - high-performance microcontroller with FRAM memory 02.05.2015

The MSP430FR5969 from Texas Instruments is an innovative microcontroller that uses FRAM instead of FLASH.

FRAM memory has an advantage over traditional FLASH memory for microcontrollers, which determines its reliability and ease of use.

Of the additional advantages, it is worth noting the possibility of using the FRAM-memory area as random access memory, and the size of this area is set by the user. Also, the developer can set the protection of certain areas of memory from different types of access (read / write).

The MSP430FR5969 integrates powerful analog peripherals, including a 12-bit ADC with voltage reference and a 16-input analog comparator. For communication with external devices, the controller provides UART, SPI, I2C interfaces, as well as an IrDA modulator for use in data exchange interfaces using infrared radiation. The UART and I2C interfaces can be used to program or update the controller software using the BSL bootloader. All GPIO pins support CapTouch capacitive sensor technology.

A significant advantage is the presence of the MSP-EXP430FR5969 debug board with the EnergyTrace ++ tool implemented on it.

EnergyTrace++ is the only technology that allows you to track the consumption of the microcontroller, the operating mode of the core and the status of each of the peripheral modules in real time. This allows for maximum optimization of the system's power profile and improves the efficiency of the microcontroller software.

The MSP430FR5969 is ideal for applications that frequently overwrite data in the ROM area and for long battery life applications.
