Abstract: There is disclosed in one example a ransomware mitigation engine, including: a processor; a convolutional neural network configured to provide file type identification (FTI) services including: identifying an access operation of a file as a write to the file or newly creating the file; computing a byte correlation factor for the file; classifying the file as belonging to a file type; determining with a screening confidence that the file type is correct for the file; determining that the screening confidence is below a screening confidence threshold; and circuitry and logic to provide heuristic analysis including: receiving notification that the confidence is below the confidence threshold; performing a statistical analysis of the file to determine a difference between an expected value and a computed value; determining from the difference, with a detection confidence, that the file has been compromised; and identifying the file as having been compromised by a ransomware attack.

Abstract: An opposed conical elastomeric bearing assembly includes a first conical elastomeric bearing with a first inner race and a first outer race, and a second conical elastomeric bearing with a second inner race and a second outer race. Assembling the opposed conical elastomeric bearing assembly may include positioning an outer surface of the second outer race in contact with an inner surface of the first outer race. Assembling the opposed conical elastomeric bearing assembly further includes applying an axial force to urge the first conical elastomeric bearing and the second conical elastomeric bearing together such that a leading edge of the second inner race contacts a shoulder of the first inner race, and, while applying the axial force, deforming a projecting portion of the first inner race such that an outer diameter of the projecting portion is expanded to frictionally engage an inner surface of the second inner race.

Abstract: An apparatus that includes a first member pivotably connected to a second member that is pivotably connected to a third member. The second member pivots about a first axis with respect to the first member and the third member pivots about a second axis with respect to the second member. The apparatus includes a first encoder configured to determine a first angle of rotation between the first member and the second member and a second encoder configured to determine a second angle of rotation between the second member and the third member. The first and second axes may be transverse to each other. The apparatus may be connected to a rotary aircraft with an object connected to the third member via a cable. The encoders may communicate with a display and/or a processor to display the location and/or movement of the object with respect to the rotary aircraft.
