Abstract: The disclosure relates to improved friction drive systems, control algorithms for friction drive systems, and automatic traction control for friction drive systems. Embodiments of friction drive systems and methods may improve control over an amount of normal force between a contact surface on a friction drive (e.g., disposed on a drive motor) and a tire or wheel of a wheeled vehicle. Embodiments of friction drive systems and methods may dynamically adjust the normal force between the contact surface and the tire or wheel in response to rapidly changing conditions, such as weather, road surface, and/or tire inflation. Embodiments of an automatic traction control system may adjust the normal force to avoid slippage while minimizing tire wear and maximizing battery efficiency. Embodiments of friction drive systems and methods may allow a user to calibrate or adjust the amount of normal force delivered based on their preferences or based on a selected mode of operation.

Abstract: An improved personal propulsion device that generally imparts thrust directly to the user. The device allows hands free control of thrust magnitude and direction so both hands can grasp and control bicycle handlebars and brakes, watercraft paddles, ski poles or other apparatuses. The device is adjustable vertically, on the users' back, higher to allow sitting in a canoe or wheelchair and lower for standing on skates, skis, kick scooters etc. In one embodiment, the device includes an air compressor that is operatively connected to a cam mechanism engaged with the propulsion mechanism to provide compressed air. In another embodiment, the device includes a gap control mechanism to reduce or increase the size of the air inlet gap between the lip of the propeller shroud and an air horn to decrease noise levels or increase propulsion. The air horn can be gradiently flexible and warpable to allow controlled movement thereof.

Abstract: An improved personal propulsion device that generally imparts thrust directly to the user. The device allows hands free control of thrust magnitude and direction so both hands can grasp and control bicycle handlebars and brakes, watercraft paddles, ski poles or other apparatuses. The device is adjustable vertically, on the users' back, higher to allow sitting in a canoe or wheelchair and lower for standing on skates, skis, kick scooters etc. A user on a bicycle may prefer to lean forward for comfort and aerodynamics, a device adjustment compensates and delivers level thrust. A user on a snowboard or skateboard stands oblique to the direction of travel, a device adjustment allows in line thrust. Both users' hands and arms are free to balance, protect others by pushing off or break a fall. The present invention can be provided as separate modules that allow interchangeability and use with a direct drive mechanism.

Abstract: The present invention is a collapsible two-wheeled vehicle, wherein the vehicle comprises a down tube and a horizontal stay that are pivotably connected to one another at midsections thereof as well as being slidably connected to steering and seat assemblies, respectively. The slightly canted arrangement of the various members and assemblies provides a rigid structure to support an operator during use yet allows the vehicle to be collapsed to a compact size for storage and shipping. The vehicle may be folded or collapsed in the form of an “X”, bringing the wheels into a side-by-side position, to reduce its overall size without compromising its structural rigidity when reopened.
