Latest Patents

Lucas's latest patents showcase his expertise and ingenuity in dynamic nuclear polarization and well logging techniques.

1. **Method of Carrying Out Dynamic Nuclear Polarization**: This patent describes a sophisticated approach to hyperpolarizing a sample with a molecular structure comprising at least two J-coupled non-integer spin nuclear species. The method involves cooling the sample to a solid form while exposing it to a homogeneous magnetic field. Following this, the hyperpolarized sample is dissolved or melted, and a polarization holding RF pulse sequence is applied, redistributing the nuclear spin populations in a non-equilibrium state. This innovative process ensures that the nuclear spins transfer adiabatically to stable equilibrium levels within the specified relaxation time constants.

2. **Nuclear Magnetic Resonance Measurements in Well Logging Using Motion Triggered Pulsing**: This patent introduces a pulsed NMR tool design, featuring a magnet arrangement that creates a static magnetic field of uniform strength in the formation surrounding a borehole. The tool utilizes an RF coil to generate pulsed RF fields, allowing for precise control over the alignment and precession of nuclear spins. Motion sensors integrated into the tool produce signals that inform a processor to time the tipping pulse accurately, ensuring optimal performance even in dynamic conditions.
