A cleaning device for a surface, such as a windshield of a vehicle, includes an active positioning system and a cleaning head. The active positioning system is configured to deploy from a storage position hidden from view within a covered storage space and to position the cleaning head upon the windshield. The active positioning system includes a first extension member and a second extension member that move relative to one another to position the cleaning head, and also move the cleaning head across the windshield along a path. The cleaning head can have a brush portion configured to agitate debris from the window, and a drying portion configured to dry the window after cleaning. The cleaning device can be controlled via a touch-screen display in the vehicle, enabling a user to direct that specific portions of the windshield be cleaned as desired.

A vehicle assembly according to an exemplary aspect of the present disclosure includes, among other things, a cargo bed of a vehicle and a crossbar spanning the cargo bed. The crossbar is slidable relative to the cargo bed. A lift assist device is mounted to the crossbar. The assembly can include a passenger side rail mounted to a passenger side wall assembly of the cargo bed, and a driver side rail mounted to a driver side wall assembly of the cargo bed. The crossbar can be slidably coupled to both the driver side rail and the passenger side rail.

Drones with propulsions systems supported in a housing are provided where the orientation of the housing is independent from the orientation of the propulsion system. Drones are provided where a propulsion system is rotatable about a first axis and a second axis that is perpendicular to the first axis, permitting the propulsion system to assume substantially any position with a sphere. Drones are provided where a bladeless inner tube is rotatable about a first axis and a second axis that is perpendicular to the first axis, permitting the inner tube to assume substantially any position within a sphere. Drone systems are provided with connectable unit drones. An unmanned land vehicle is provided having a wheel assembly that is rotatable about a first axis and a second axis that is perpendicular to the first axis, permitting the wheel assembly to assume substantially any position with a sphere.

A magnetorheological damper, wherein the damper comprises a housing that is at least partially filed with a magnetorheological fluid, and a magnetorheological valve disposed within the housing. The valve includes a magnetically permeable core having at least one coil reservoir formed therein, and at least one conductor coil, wherein each conductor coil is disposed around a portion of the core within a respective one of the coil reservoir(s). The valve additionally includes a fluid flow path adjacent the conductor coil(s). The fluid flow path is structured and operable to allow the magnetorheological fluid to flow adjacent the conductor coil(s). The valve further includes at least one coil cover, wherein each coil cover is disposed over a respective one of the coil(s) such that the respective coil is protected from exposure to magnetorheological fluid flowing through the fluid flow path.

A flagpole adapter for a gooseneck hitch is provided. The flagpole adapter can include a shank that is configured to insert into the receiver of a gooseneck hitch. The flagpole adapter can also include a tube that extends upwardly from the shank and that is configured to receive a flagpole. The flagpole adapter can further include a flagpole securing assembly for securing a flagpole that is inserted into the tube. Because the flagpole adapter is inserted into the receiver of a gooseneck hitch, flags flown using the flagpole adapter will be positioned centrally within the bed of the truck.
