For most of us who are not astronomers, the image that comes to mind when describing a reflecting telescope is of a huge instrument in its own domed-roof building on a mountain top. But a ...

Abstract: This paper presents and experimentally validates various topologies of one-port reflective-mode phase-variation permittivity sensors based on weakly coupled step impedance resonators (SIRs), ...

There are a lot of options for local weather stations; most of them, however, are sensors tied to a base station, often requiring an internet connection to access all features. [Vinnie] over at ...

Abstract: This study introduces a novel algorithm that combines a custom-developed capacitive proximity sensor with LiDAR. This integration targets the limitations of using single-sensor systems for ...
