Abstract: The propulsion unit including a casing having an inner curved surface and an outer curved surface, at least one tire disposed within the casing within a duct defined by the inner curved surface and the outer curved surface, a first propeller and a second propeller having a plurality of blades extending from within the casing toward a center axis of the casing, and one or more motors housed within the casing, the one or motor being configured to operate the at least one tire, the first propeller, and the second propeller independently of one another. There is also provided a vehicle with one or more propulsion units of the present disclosure.

Abstract: The present disclosure discusses a transportation vehicle configured for transforming between a drive mode and a flight mode. The vehicle includes a chassis with a body coupled thereto and a plurality of fenders coupled to the body. Each of the fenders includes a rim comprising spokes and a tire configured to rotate during drive mode and a suspension configured to pivot the plurality of fenders from a substantially vertical orientation during drive mode to a substantially horizontal orientation during flight mode. Each of the fender also includes a propulsion mechanism configured to rotate independently of the rim to generate lift during flight mode and a motor configured to independently provide rotational force to the tire built into the rim during drive mode and rotational force to the propulsion mechanism during flight mode.

Abstract: A bag reloading garbage unit includes a base with a compartment therein for containing a plurality of separably interconnected garbage bags. The base includes a slot through which the garbage bags can be pulled into position for use. The base includes at least two articulable guide arms with guide channels therein for engaging with a garbage bag being pulled into position. When the garbage bag top arrives at the top of each articulable guide arm, the top of the garbage bag is secured in position within the unit. The guide arms operate to open and close the garbage bag. When the garbage bag is full, it is closed and removed by pulling upward and pulling with it a connected garbage bag into position in the garbage unit.
