[Global Science and Technology Comprehensive Report] According to news of the US media on June 18, several US technology company CEOs will participate in the founding meeting of the US Science and Technology Commission on June 19, and will meet with President Donald Trump of the United States. Many of these executives have publicly opposed the Trump administration’s immigration and climate change policies in recent months.
Senior executives attending the conference included: Amazon CEO Jeff Bezos, Apple CEO Tim Cook, Microsoft CEO Satya Nadella, IBM CEO Ginni Rometty, Oracle CEO Safra Catz, and Eric Schmidt, the chairman of the alphabet. In addition, according to Axios and Politico reports, the US President’s senior assistant and son-in-law Jared Kushner will also attend. The topics of this meeting will be related to how the federal government can better use information technology to H-1B policies.
The federal government established the U.S. Commission for Science and Technology in May. Its main function is to coordinate the vision, strategy, and direction of the federal government in the use of information technology and digital services, and to consult with policy makers, and to coordinate the federal government’s use of information technology and digital services. process.
President Trump has always been dissatisfied with the government’s lagging computer system and complained that the United States can easily become a target of cyber attacks. He added, "However, computer maintenance costs are a huge expense." Trump signed an executive order in May to strengthen the country's outdated network and critical infrastructure cyber security. One of the key developments is the move to more secure cloud services.

What is a miniature slip ring? Miniature slip rings are rotary electrical connectors that allow power and data to be transferred between a stationary and rotating structure. They are often used in medical, military, and aerospace applications where size and weight are critical factors.
A miniature slip ring typically consists of two parts: a stationary housing and a rotating contact assembly. The contact assembly contains the brushes that make electrical contact with the rotating structure, as well as the rings that conduct current or data.
The housing can be made from any number of materials, including metals, plastics, and composites. It is typically designed to be as small and lightweight as possible while still providing adequate strength and durability.
The contact assembly is made from precious metals such as gold or silver in order to provide good electrical conductivity.
Technology improves with the continuous development of precision machinery. The more sophisticated the equipment, the smaller the volume will be. And the space that can be accommodated for installing the slip ring is also very small. The key parts of some equipment are quite a district. Especially in the high-end military, aerospace and aviation fields. 360-degree rotation is required to transmit current and signals. And the installation space is greatly reduced. It is to make the equipment work more smoothly. Therefore, it is necessary to design the slip ring to be small and exquisite. Otherwise, it won't meet the needs of the installation.
At the same time, we have moved with the continuous development of science and technology. Various high-end precision instruments have been developed. It requires the slip ring to transmit the current amount of general power. Also often undertake the transmission of weak electrical signals and various weak signals. The transmission medium is wider, and the number of loops of the slip ring is increasing.
