An auto-balancing transportation device configured for being ridden in a foot forward or sideways standing position. The rider platform has front and rear foot platform areas and two connecting members, located on opposite lateral sides of the device, that couple the front and rear platform areas. Two drive wheels are located under or through the platform. The front and/or rear platform areas are movable or twistable so as to alter the fore-aft tilt of one or more of the connecting members. Position sensors associated with each connecting member are used to drive a corresponding drive wheel. In this manner, differences in fore-aft tilt angle of the two connecting members achieves a turning of the device.

Various powered personal mobility vehicles are disclosed. In some embodiments, the vehicle can include a deck having a forward portion, a rearward portion, and a neck portion. A front swivel wheel assembly and a rear swivel wheel assembly can be connected with the deck. In some embodiments, the front swivel wheel assembly comprises a motor.

Methods and systems are provided for concave footpads for a personal transport device. In one example, the concave footpads may be coupled to the personal transport device, arranged between an operator's feet and an upper surface of the personal transport device, the upper surface including a pressure transducer.

The present specification discloses wheel mounts for personal vehicles, such as skateboards and scooters. Wheel mount embodiments disclosed herein provide for the interchangeable mounting of wheels having differently shaped wheel cores. The present invention allows users to forego the previous limitation of having a specific wheel mount that only provides for the mounting a specific wheel having one specific wheel core geometry. Embodiments can be utilized on motorized personal vehicles, such as motorized skateboards and scooters that utilize various motors, such as direct drive or belt drive motors.

A skateboard with a standing surface for a user and with two wheel axles, on each of which at least two wheels are rotatably mounted, with a mounting for connecting the wheel axles to the standing surface and with steering gears in order to pivot the wheel axles about a vertical axis for steering by tilting the standing surface about its longitudinal axis from a starting position intersecting the longitudinal axis perpendicularly, characterized in that the wheel axles are arranged on the underside of the standing surface.

An apparatus for charge-assisted release of a ski binding includes an explosive material, a battery, an electrical circuit, and a processor. The explosive material is mounted on or in a ski, a ski boot, and/or a ski binding. The apparatus also includes The electrical circuit extends from the explosive material to the battery, the electrical circuit including a switch having a connected state in which the battery and the explosive material are electrically connected through the switch and a disconnected state in which the battery and the explosive material are electrically disconnected. The processor is electrically coupled to the switch and configured to generate an output signal that transitions the switch from the disconnected state to the connected state in response to an input signal from one or more sensors.

An auto-balancing transportation device having a compact form. Left and right foot platform sections are coupled for fore-aft tilt angle movement relative to one another. Left and right wheels are provided under the respective foot platforms. With a rider's weight directed primarily downward onto the wheels and not onto the coupling structure, the coupling structure may have sufficient space to house the battery. In addition, more efficient and lighter weight supports and bearing arrangements may be used in the coupling structure. Various embodiments are disclosed.

An auto-balancing transportation device having a wheel structure and foot platforms that pivot between an in-use and a stowed position. The pivot axis for each platform is provided within the wheel structure so that the force exerted by a rider when stepping on a foot platform is applied to the wheel structure at a point within the wheel structure, as opposed to external to it, which is unstable and may cause the device to tip over.

A self-stabilizing, one-wheeled electric skateboard may include improved features. In some examples, the vehicle includes a status indicator viewable through a slot formed in an upper surface of the board. In some examples, the vehicle includes a convertible carrying handle transitionable between stowed and deployed positions. In some examples, the vehicle includes an interchangeable fender and fender substitute that may be removably coupled to an upper surface of the board. In some examples, a motor controller of the vehicle may operate a field-oriented control (FOC) scheme configured to control the electric motor by manipulating a direct current aligned with a rotating rotor flux angle and a quadrature current defined at ninety degrees from the rotating rotor flux angle. In some examples, the motor controller may be configured to permit intuitive dismounting of the vehicle by tilting and/or moving the vehicle backward.

A device which may include first and second cross skate bodies each having a frame configured to support at least first and second wheels situated inline of each other, each frame having at least one compartment configured to position a corresponding power source of first and second power sources; first and second foot couplers, each foot coupler configured to couple a foot of a user to a corresponding cross skate body of the cross skate bodies; a first traction motor coupled to drive at least one of the first and second wheels of the first cross skate body; a second traction motor coupled to drive at least one of the first and second wheels of the second cross skate body; and a controller which may be configured to: receive a drive signal from a drive controller, and control the first and second traction motors to drive the corresponding wheels in accordance with the drive signal.
