Latest Patents

One of Hai Dong's latest patents is the "Digital Q-Meter for continuous-wave NMR." This invention describes a method to perform continuous-wave NMR measurements of nuclear magnetization at high magnetic fields, above 2.5 T, without analog down-mixing. An FPGA controls a digital clock pulse that stimulates a resonant circuit and provides a reference signal. An algorithm determines the real portion of a resonant circuit signal near the Larmor frequency of the species of interest using only two measurements of the waveform per cycle. The FPGA automatically alters a variable capacitance to tune the resonant circuit to the Larmor frequency.

Another notable patent is the "Method and apparatus to digitize pulse shapes from radiation detectors." This invention features a field-programmable gate array-based multi-channel flash ADC unit combined with a high-speed multi-lane data communications channel, providing a complete but easily expandable high-speed data acquisition system. This apparatus and method allow for high-speed pulse-shape digitalization, enabling position resolution imaging of particles with a range of energies. It is scalable to efficiently capture coincident data from large electromagnetic detector arrays.
