Latest Patents

David H. Herlihy holds a patent for a Nuclear Quadrupole Resonance (NQR) system. This system and method are designed for detecting at least one material under test (MUT). The NQR measurement system includes a waveform generator that generates a continuous wave (CW) input signal comprising one or more frequencies. An RF shielded chamber is utilized to receive the MUT, which can be carried by a person walking through the chamber. A probe within the chamber illuminates the MUT with the CW signal while simultaneously receiving possible NQR emissions from the MUT. A bridge circuit is employed to cancel the strong excitation CW signal from the generator, which would otherwise mask the weak NQR emissions from the MUT. A detector can then identify the MUT based on the resonance signal.
