Abstract: A mobile nest for unmanned aerial vehicles (UAVs) includes a cuboid-shaped frame, staging pads, charging electronics, and exterior siding. The cuboid-shaped frame includes vertical supports positioned at corners of the cuboid-shaped frame. The staging pads are adapted for landing, launching, and charging the UAVs. The staging pads are mounted to pivot about two or more of the vertical supports. Each of the staging pads rotates into the cuboid-shaped frame when stowed and rotates out of the cuboid-shaped frame when deployed for launching or landing the corresponding one of the UAVs. The charging electronics are disposed within the cuboid-shaped frame and coupled to the staging pads to charge the UAVs when the UAVs are positioned on the staging pads. The exterior siding is mounted to the cuboid-shaped frame to provide a weather barrier that protects the UAVs from weather when the UAVs are stowed within the mobile housing structure.

Abstract: Systems and methods for assembling Unmanned Autonomous Vehicle (UAV) are disclosed herein. In one embodiment, a method for assembling a UAV includes connecting a wing spar with boom carriers to form an H-frame. The wing spar provides mounting locations for securing horizontal propulsion units, and the boom carriers provide mounting locations for securing vertical propulsion units. The method also includes attaching a fuselage body to the wing spar; attaching a pre-formed wing shell to the H-frame; and attaching pre-formed individual boom shells to their corresponding boom carriers. The H-frame provides structural frame for mounting the wing shell and the boom shells.

Abstract: A coil support with a coil of a trimmer line has a coil core with an outer wall surface and first and second axial ends. At the axial ends securing elements that project past the wall surface of the coil core are provided for positional fixation of the coil wound onto the coil core. A securing element provided at the first axial end is a support plate with a longitudinal center axis. The size of the support plate is provided in the direction of the longitudinal center axis with a greater extension than transverse to the longitudinal center axis such that the support plate in a first radial direction of the coil core is greater than in a second radial direction. The coil core is fixedly connected with the support plate and with the further securing elements that are provided on the second axial end.

Abstract: A protective shield for a cutting tool of a brushcutter or trimmer, wherein in the region of the working end of a guide tube, the cutting tool is mounted so as to be rotatable in a turning circle about an axis of rotation. A radial wall extends radially relative to the axis of rotation and at least partially shields the turning circle in an axial direction. A support channel is formed in the radial wall for receiving the working end of the guide tube. A peripheral wall adjoins the radial wall and at least partially shields the turning circle in a radial direction.
