Abstract: An automated window shutter assembly includes a pair of shutters that is each movably positioned on an exterior wall of a building. Each of the shutters is positionable in an open position or a closed position. A housing is coupled to the exterior wall of the building and the housing is positioned above the window. A pair of screws is each rotatably positioned within the housing and each of the screws is rotatable in a closing direction or an opening direction. A drive unit is positioned within the housing and the drive unit engages each of the screws. The drive unit is turned on to rotate each of the screws in the closing direction or the opening direction. A plurality of engagements each threadably engages a respective one of the screws. Each of the engagements is coupled to a respective one of the shutters for opening and closing the shutters.

Abstract: An air foil structure attachable to a semi-trailer of a tractor-trailer rig is herein disclosed, intended to produce various aerodynamic affects such as reducing turbulence, creating lift, and creating down force. The air foil apparatus is mounted to a trailer chassis and extends upwardly to a height approximately that of the cab portion of the tractor. The air foil apparatus comprises a stationary pedestal structure having a pair of attached vertical hydraulic cylinders which connect to the air foil wing portion. The hydraulic cylinders enable height adjustment of the air foil wing by an operator during transit via a remote controller within the cab area. The angle of the wing may be manually adjusted and secured in position via pivoting trunnion mounts. The current height of the air foil wing is displayed upon the remote controller allowing an operator to effectively lower the air foil wing during transit when approaching height-restricting objects.
