32Gbps transceiver from Altera

14.04.2013

The industry's first 32 Gbps transceiver implemented using programmable logic was introduced by Altera. According to the developers, this is an important milestone in the development of transceiver technology. The demonstration sample was based on an FPGA chip manufactured using the 20nm TSMC 20SoC process technology.

According to Altera, the expectations of customers participating in the early adopter program who are interested in using the next generation of Altera field-programmable gate arrays in high-throughput products are confirmed in practice. The company is said to be the only manufacturer to mass-ship 28nm FPGAs with integrated transceivers that support 28Gbps.

The transceiver in the demo showed random jitter values ​​of 240 fs and a total jitter of about 9 ps. These parameters are well within the requirements that will be required in next-generation systems with a throughput of 100 Gbps.

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. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

Ultra-Flash CSFB Technology 09.07.2014

Huawei, a global ICT solutions provider, has demonstrated its Ultra-Flash Circuit Switched Fallback (Ultra-Flash CSFB) technology for LTE TDD technology on its flagship Huawei Ascend P7 smartphone.

Huawei's Ultra-Flash CSFB technology reduces connection setup time (up to 50%) compared to 3GPP R8's CSFB technology, Huawei said to CNews, allowing LTE users to access advanced end-to-end voice services in as little as three seconds. Ultra-Flash CSFB technology was first introduced a year ago and is now available for commercial use.

“While operators strive to commercialize VoLTE in their networks, LTE voice services remain an area where there are unsolved problems,” Huawei noted. “For example, subscribers have to wait at least seven seconds for a voice call to establish a connection. "This is a record for CSFB technology in the telecom industry. This is an impressive result for 4G voice services."

To implement Ultra-Flash CSFB, operators do not need to rebuild their networks. According to Huawei, the technology is simple, cost-effective, and, most importantly, supports seamless upgrades to VoLTE in the future. The company is currently in talks with several operators to test Ultra-Flash CSFB.
