Astronomy and Electromagnetics

A millimeter-wave fall detection sensor is shown in the image. With the increase in an aging population and the growing demand for in-home care, safety monitoring for the elderly and disabled has become particularly important. Traditional visual monitoring systems present issues of privacy leakage and strong invasiveness in highly private settings such as bathrooms and bedrooms. To solve these problems, I propose a deep-learning-based millimeter-wave fall detector that enables real-time monitoring of behaviors like falls in the home environment. I train this detector as an AI model to accurately detect elderly falls. Given the non-contact and high privacy protection advantages of millimeter-wave radar technology, this system is especially suited for privacy-sensitive home settings.

However, millimeter waves, being an electromagnetic wave in the millimeter range, can be affected by solar eruptions. Solar eruptions emit magnetic fields, leading to magnetic reconnection with the Earth's magnetic field, which then interferes with communication systems and electromagnetic fields. This is how astronomy impacts electromagnetism.
