Latest Patents
One of his 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 significant patent is the "Remote vacuum or pressure sealing device and method for critical isolated systems." This invention provides a remote vacuum or pressure sealing apparatus and method for creating a radiation-tolerant, remotely prepared seal that maintains a vacuum or pressure-tight seal throughout a wide temperature range. The apparatus includes a fixed threaded sealing surface on an isolated system, a gasket, and an insert consisting of a plug with a protruding sample holder. The insert coupling device is designed for inserting samples within the isolated system and includes various features for effective operation.
