The proposed innovative design leads to unprecedented power conversion efficiency and improved versatility. A recently developed wirelessly powered 5G relay could accelerate the development of smart factories, report scientists from Tokyo Tech. By adopting a lower operating frequency for wireless power transfer, the proposed relay design solves many of the current limitations, including range and efficiency. In turn, this allows for a more versatile and widespread arrangement of sensors and transceivers in industrial settings.

One of the hallmarks of the Information Age is the transformation of industries towards a greater flow of information. This can be readily seen in high-tech factories and warehouses, where wireless sensors and transceivers are installed in robots, production machinery, and automatic vehicles. In many cases, 5G networks are used to orchestrate operations and communications between these devices.

To avoid relying on cumbersome wired power sources, sensors and transceivers can be energized remotely via wireless power transfer (WPT). However, one problem with conventional WPT designs is that they operate at 24 GHz. At such high frequencies, transmission beams must be extremely narrow to avoid energy losses. Moreover, power can only be transmitted if there is a clear line of sight between the WPT system and the target device. Since 5G relays are often used to extend the range of 5G base stations, WPT needs to reach even further, which is yet another challenge for 24 GHz systems.

Four-legged animals are innately capable of agile and adaptable movements, which allow them to move on a wide range of terrains. Over the past decades, roboticists worldwide have been trying to effectively reproduce these movements in quadrupedal (i.e., four-legged) robots.

Computational models trained via reinforcement learning have been found to achieve particularly promising results for enabling agile locomotion in quadruped robots. However, these models are typically trained in simulated environments and their performance sometimes declines when they are applied to real robots in real-world environments.

Alternative approaches to realizing agile quadruped locomotion utilize footage of moving animals collected by and cameras as demonstrations, which are used to train controllers (i.e., algorithms for executing the movements of robots). This approach, dubbed “imitation learning,” was found to enable the reproduction of animal-like movements in some quadrupedal robots.

There are several ways the industry is addressing this energy crisis. First, computing hardware has gotten substantially more energy efficient over the years in terms of the operations executed per watt consumed. Data centers’ power use efficiency, a metric that shows the ratio of power consumed for computing versus for cooling and other infrastructure, has been reduced to 1.5 on average, and even to an impressive 1.2 in advanced facilities. New data centers have more efficient cooling by using water cooling and external cool air when it’s available.

Unfortunately, efficiency alone is not going to solve the sustainability problem. In fact, Jevons paradox points to how efficiency may result in an increase of energy consumption in the longer run. In addition, hardware efficiency gains have slowed down substantially, as the industry has hit the limits of chip technology scaling.

Small-angle scattering (SAS) is a powerful technique for studying nanoscale samples. So far, however, its use in research has been held back by its inability to operate without some prior knowledge of a sample’s chemical composition. Through new research published in The European Physical Journal E, Eugen Anitas at the Bogoliubov Laboratory of Theoretical Physics in Dubna, Russia, presents a more advanced approach, which integrates SAS with machine learning algorithms.

South Korea is poised to enhance its defense capabilities with the launch of a revolutionary laser-based anti-aircraft weapon. Hanwha Aerospace, a leading South Korean defense firm, has begun production following a contract signed in late June with the Defense Acquisition Program Administration (DAPA). The contract, worth KRW100 billion (USD72.5 million), mandates the delivery of the ‘Laser Based Anti-Aircraft Weapon Block-I’ systems to the Republic of Korea (RoK) Armed Forces starting later in 2024. This advanced weapon system, developed since 2019 with an investment of KRW87.1 billion (approximately USD63 million), is set to bolster South Korea’s defense against emerging threats, particularly from North Korea.

DAPA has described the Block-I system as a new-concept future weapon system that employs a laser generated from an optical fiber to neutralize targets. The weapon is engineered to accurately strike small unmanned aerial vehicles (UAVs) and multicopters at close range. This innovative technology is silent, ammunition-free, and operates solely on electricity, making it a cost-effective solution, with each firing costing about KRW2,000. The laser anti-aircraft weapon (Block-I) represents a significant advancement in our defense capabilities. If the output is improved in the future, it could become a game-changing asset on the battlefield, capable of responding to aircraft and ballistic missiles.

Dubbed the “StarWars Project,” the weapon’s development is a crucial element of South Korea’s strategy to modernize its defense systems amidst North Korea’s increasing weapons advancements. The laser beam emitted by the weapon is invisible to the human eye and produces no sound, adding to its tactical advantages. Upon deployment, South Korea will be the first country to operate this type of advanced laser weapon system, marking a significant milestone in military technology. This strategic development underscores South Korea’s commitment to maintaining a robust and modern defense posture in an increasingly complex security environment.
