Publication number: 20180275223Abstract: Some methods and configurations are disclosed for high bandwidth acquisition of magnetometer data with increased sensitivity. Some embodiments provide for increased bandwidth and sensitivity of the magnetometer by eliminating a reference signal for full repolarization of the magneto-optical defect center material prior to acquisition. Elimination of the reference signal eliminates the time needed to repolarize the magneto-optical defect center material and the acquisition time for the reference signal. Some implementations can include activating a radiofrequency (RF) pulse sequence to apply an RF field to the magneto-optical defect center material and acquiring a magnetic field measurement using the magneto-optical defect center material. The magnetic field measurement may be acquired independent of a reference magnetic field measurement.Type: ApplicationFiled: March 24, 2017Publication date: September 27, 2018Applicant: Lockheed Martin CorporationInventors: Gregory Scott Bruce, Peter G.

Patent number: 10082376Abstract: A projectile has a liner forming an interior void, and a core disposed in a first region of the void proximal to a trailing end portion of the liner, with a portion of the void disposed forward with respect to the core. An outer jacket covers a leading end portion of the liner to enclose the interior void. When the projectile impacts a target object, the core travels in a direction of flight through the leading end portion of the liner to impact the object. When the projectile impacts a target surface at a non-zero angle of approach with respect to the normal of the target surface, the projectile creates a deformation in the target surface immediately before the core travels through the leading end portion of the liner to impact the target. This deformation reduces the probability that the core will ricochet off the deformed portion of the surface.Type: GrantFiled: April 8, 2016Date of Patent: September 25, 2018Assignee: Lockheed Martin CorporationInventors: Toby D.
