Abstract: A linear actuator includes a support structure having a first face, and a second face opposite the first face; a first rack secured to the first face; a second rack secured to the second face; a first compound gear and a second compound gear; and a drive gear engaged with the first input gear on a first side of the drive gear, and engaged with an idle gear on a second side of the drive gear, opposite the first side of the drive gear. The first and second compound gears are configured for a simultaneous linear motion in one of two opposing directions.

Abstract: An actuator is provided which includes a stationary frame; an output plate disposed within said stationary frame; a top plate; a stator disposed between said stationary frame and said top plate, said stator describing an annulus; a rotor disposed within the annulus of said stator; a principal bearing disposed between said stationary frame and said output plate; a pinion gear; and a star gear which meshes with said pinion gear.

Abstract: A controller computing system, including a plurality of controllers, each controller configured to i) calculate a respective output based on a current set point and ii) output a timer signal; a cyber security manager (CSM) computing module configured to: output a nominal signal indicating that the current set point is a non-malicious set point when the CSM computing module receives each of the timer signals from each of the plurality of controllers; and output a reset signal indicating that the current set point is a malicious set point when the CSM computing module receives less than each of the timer signals from the plurality of controllers.
