Latest Patents

Wenhan Li holds a patent for a "Tracing method and apparatus based on electromagnetic field." This novel tracing apparatus includes an electromagnetic transmitting system, a multi-frequency transmitting antenna, electrodes, and a receiver. The electromagnetic transmitting system is positioned at an upstream point and consists of a generator and a transmitter equipped with a capacitor. The transmitting antenna penetrates into a detected aquifer through karst collapse or a drill hole. The electrodes and the receiver are located at a downstream point, featuring two pairs of electrodes that are orthogonally distributed within a cofferdam formed by downstream water. The receivers collect electric signals from the electrodes. This apparatus leverages the good electrical conductivity of water, using electromagnetic signals as tracers for rapid observation. Compared to traditional tracers, electromagnetic signals propagate quickly in water, are stable in their properties, and are free of pollution. This innovation effectively resolves issues associated with traditional tracers, which often suffer from poor timeliness and environmental concerns.
