With a total of two patents to his name, Shaw's work is at the forefront of enhancing security measures in various applications.
Latest Patents
Shaw's latest patents focus on systems and methods for contraband detection using nuclear quadrupole resonance (NQR). The first patent describes a system designed to detect target substances within a class of explosives and narcotics that contain quadrupolar nuclei. This system applies an RF signal to a coil to excite the substance under test. If the target material is present, an NQR signal is picked up by the same coil. This signal is then compared with known NQR signals in terms of frequency and amplitude. A signal is displayed appropriately if a threshold value of the NQR signal is equaled or exceeded. The coil is statically tuned by adjusting the location or capacitance values of static tuning capacitors. An auto-tune feature is employed after the specimen is inserted into the coil. Effective RFI shielding is also provided to prevent external contaminating signals from being detected by the coil and to prevent RF signals from escaping from the scanner. The invention includes methods for performing tests with the system.
The second patent mirrors the first in its focus on detecting target substances using NQR technology. It similarly applies an RF signal to a coil and utilizes an auto-tune feature for optimal performance. The effective RFI shielding is a critical aspect of this invention, ensuring accurate detection without interference from external signals.
