Solution Approach 1:

The patent implements universality by designing a sensing apparatus that can perform multiple sensing functions using primarily radio waves. The system achieves multi-functional capability through signal processing techniques that enable detection of various physical quantities (distance, velocity, temperature) using a single integrated platform, thereby improving sensing accuracy without proportionally increasing device complexity.
