Abstract: Trajectory estimate for a sub-sonic projectile can be derived from sampling a wake contribution of an acoustic signal detected at a multi-detector array. The wake contribution is sampled, in time, and the samples are processed to determine a bearing estimate for the projectile from which the acoustic wake derives.

Abstract: Detection of a trajectory of a supersonic projectile is carried out derived from a plurality of acoustic detection signals. From these acoustic detection signals, two or more shockwave-derived trajectory estimates can be derived. Further, a wake derived trajectory bearing estimate can be derived, from which disambiguation of the shockwave-derived trajectory estimates can be effected.

Abstract: The derail warning system may include a solar-powered LED indicator for derail or switch. The derail warning system may also include an orientation sensor that automatically turns on depending on the orientation of the derail (up or down), derail metal flag, or switch indicator flag. The derail warning system may bring more visibility with a 360-degree LED that is solar powered and may detect orientation and turn on based on the position of the derail, switch, or flag. The derail warning system may use a unique acceleration sensor or g-sensor that can detect orientation movement and automatically turn on or off and be fully charged to operate day or night. The derail warning system may also include a data-logging microprocessor to determine a time stamp of position and location.

Abstract: The present disclosure generally relates to a SOT-MRAM cell that has a spin Hall effect layer and a magnetic tunnel junction. The magnetic tunnel junction is disposed at an edge of the spin Hall effect layer. In order to write the cell, current is applied through the spin Hall effect layer to create spin accumulation of z-polarized spins under the free layer due to the spin Hall effect. The spins exert a spin torque on the free layer via spin diffusion. Based upon the design, the SOT-MRAM cell has deterministic switching of the perpendicular free layer with the spin Hall effect layer without application of an external magnetic field.
