Patent number: 10725124Abstract: A system for magnetic detection includes a nitrogen vacancy (NV) diamond material comprising a plurality of NV centers, a radio frequency (RF) excitation source configured to provide RF excitation to the NV diamond material, an optical excitation source configured to provide optical excitation to the NV diamond material, an optical detector configured to receive an optical signal emitted by the NV diamond material, and a controller. The optical signal is based on hyperfine states of the NV diamond material. The controller is configured to detect a gradient of the optical signal based on the hyperfine states emitted by the NV diamond material.Type: GrantFiled: March 5, 2018Date of Patent: July 28, 2020Assignee: LOCKHEED MARTIN CORPORATIONInventors: Brian P. Boesch, Gregory Scott Bruce, Jeff D. Cammerata, David Nelson Coar, Laird Nicholas Egan, Bryan Neal Fisk, Wilbur Lew, Arul Manickam, Stephen Michael Sekelsky, John B. Stetson, Jr., Peter G.

Patent number: 10277208Abstract: A magnetic waveform generator circuit includes a first switch coupled to a first rectifier element at a first node, a first capacitor coupled, at a second node to the first switch, and to a fourth node, a second capacitor coupled, at a third node to the first rectifier element, and to the fourth node, and an inductor coupled between the first and the fourth nodes. The first switch is operable to be in an ON state during a first time period and in an off state during a second time period. The first switch and the first rectifier element are configured to enable the inductor to generate, during the first and the second time periods, a magnetic field having a waveform resembling a positive half-cycle of a triangular waveform.Type: GrantFiled: March 6, 2017Date of Patent: April 30, 2019Assignee: LOCKHEED MARTIN CORPORATIONInventors: James Michael Krause, James P. Mabry, Elton Pepa
