Abstract: There is provided an electrically-powered material-transport vehicle having a vehicle-charging contact on one side of the vehicle, and a second vehicle-charging contact on the opposite side of the vehicle. The vehicle has a load-bearing cap that covers the top of the vehicle, and a cap elevator for raising and lowering the cap. The cap can be raised and lowered to a transit position, a payload-engagement position, a charging position, and a maintenance position. In the transit position and payload-engagement position, the cap covers the vehicle-charging contacts so that they are not exposed. In the charging position, the cap is raised so that the vehicle-charging contacts are exposed. The vehicle can enter a charging-dock with the cap in the charging position in order to recharge the vehicle's battery.

Abstract: Systems and methods for transporting objects using a cart that is driven by human action or self-driving vehicle is disclosed. The cart system and method comprises a chassis portion supporting a payload to be moved by the cart. The cart system further comprises of a first side rail and a second side rail. A first front wheel and first rear wheel is attached to the first side rail and a second front wheel and second rear wheel is attached to the second rail. The handle portion pushes the cart which comprises of a handle bar supported by vertical support members. The brake actuator is used to engage and release the brakes on the rear wheel. A horizontal engagement bar is used which comprises of a plurality of engagement pads. A payload-bearing surface bears payload such that the payload can be transported by the cart.

Abstract: A guard is provided for use with a flexible drive coupling of a vehicle having a swingarm-type suspension, the flexible drive coupling being for coupling a transmission output sprocket to a wheel sprocket. The guard has a drive coupling guard portion; a pivoting end; a wheel end; a wheel end attachment portion for attaching the wheel end of the guard to the vehicle at a first attachment point; and a pivoting end attachment portion for attaching the pivoting end of the guard to the vehicle at a second attachment point such that the guard is pivotable about the second attachment point.

Abstract: A tank for storing a fluid is provided. The tank has an outer shell defining an inner volume for containing the fluid, a filler opening in the outer shell for placing the fluid into the tank, and a partition within the outer shell. The partition divides the inner volume into a first lower portion, a second lower portion, and a common portion. A first drain opening is located in the first lower portion and a second drain opening is located in the second lower portion. The partition separates the first lower portion from the second lower portion such that when the tank is in an operating position the fuel is prevented from passing between the first lower portion and the second lower portion.
