Latest Patents

Smith holds a patent for a "Method of and apparatus for nuclear quadrupole resonance testing a sample." This innovative method involves applying excitation to a sample in a way that allows for the extraction of both phase and amplitude information from the response signal. The technique resolves the signal into two components, which is particularly useful when parameters such as radio-frequency field strength vary with position. This capability can indicate the distribution of nuclei within the sample, especially through the phase of the response signal. Additionally, positional information can be gathered by measuring from two or more reference points, which may be employed in imaging. The phase information enhances the signal-to-noise ratio in other methods that previously relied solely on amplitude information, aiding in distinguishing genuine NQR response signals from spurious ones.
