➀ MO Valve Company shifts focus to industrial solid-state devices up to 6000 Mc/s, prioritizing communication bandwidth over high-power applications;

➁ An export division is established, with microwave equipment attracting attention in Paris, aiming for a 40% export share including indirect quotas;

➂ The company abandons domestic market products (e.g., color TVs) and concentrates on industrial valves, thyratrons, and cathode ray tubes, affirming valves' continued relevance.

➀ Microsoft has announced the shutdown of Skype, with users having until May 5, 2025, to transfer their chats and contacts to Microsoft Teams.

➁ Skype, launched in August 2003, has been a key player in online messaging, especially during the recent pandemic.

➂ Despite its decline, Skype's legacy continues through Microsoft Teams, reflecting the evolution of communication technology.

Fraunhofer Heinrich-Hertz-Institut (HHI) has initiated the SUSTAINET project, a €30 million research effort to develop sustainable and resilient network technologies. The project, running from January 2025 to December 2027, aims to integrate fiber optics, radio, and mobile networks to improve network availability and sustainability. It is divided into three sub-projects focusing on advanced technologies, intelligent solutions, and sustainable network architectures.

➀ Researchers from Tohoku University have identified a new acoustic wave propagation phenomenon with potential applications in communication technology;

➁ The study involves the use of a nano-patterned array of ferromagnets to achieve a nonreciprocal diffraction pattern;

➂ This finding could lead to the development of next-generation acoustic components for communication systems.
