Abstract: A fore-aft self-balancing transportation device, typically in a pair, one for the right foot and the other for the left foot of a rider. The platform is limited in size and positioned with a top surface wholly above the drive wheel, such that the platform straddles the axis of rotation of the drive wheel. The wheel may extend laterally to enhance side-to-side stability. The devices are configured for hands-free control, a device being driven forward or backward in response to the fore-aft tilt angle of a rider's foot on the platform (and hence, the fore-aft tilt angle of that platform). Various embodiments and features are disclosed.

Abstract: A foot-controlled personal transportation device having a drive wheel and a foot platform, with the drive wheel preferably located below the platform. Device driving may be controlled by a position sensor and a control circuit that drives the device toward auto-balancing. The device can be detachably coupled to various accessories to change or expand the function of the device. The device can also exist as a permanently attached drive unit in a complete non-auto-balancing vehicle such as a skateboard or scooter.

Abstract: A water shield structure for a transportation device and the transportation device having such a water shield structure. The transportation device is preferably a self-balancing device and may include a friction drive motor. The water shield structure helps reduce the entry of moisture from a riding surface into the wheel envelope or drive mechanism of the device. The water shield structure may extend laterally from a wheel and be enclosed, at least in part, in a housing.

Abstract: A two-wheel, self-balancing transportation device having a foot platform zone associated with each wheel. Various sensor or control arrangements are disclosed. In one embodiment, torsion sensing is used to determine a rider's fore-aft weight distribution on one foot platform zone relative to the other. The torsion-based sensing is preferably combined with fore-aft platform position sensing to achieve a driving and turning of the device. In another embodiment, pressure sensors are used to determine a rider's fore-aft weight distribution on one foot platform zone relative to the other. In yet another embodiment, a relative position sensor is used to determine the relative position of movable platforms sections. Other features and embodiments are also disclosed.

Abstract: A leg scooter device having a platform to receive the foot of a user that is positioned between forward and aft wheels. An ascending member extends above the platform and contacts the lower leg of a user during use. It is through the lower leg's contact with the ascending member and the placement of one or both of the user's feet on the platform that the user “senses” the devices and controls it. The ascending member may be movable and/or configured to be biased toward contact with the user. Various embodiments are disclosed.
Abstract translation: 具有平台以接收位于前轮与后轮之间的使用者的脚的腿踏板车装置。 升降构件在平台的上方延伸，并在使用过程中与使用者的小腿接触。 通过小腿与上升构件的接触以及将用户脚中的一个或两个脚放置在平台上，使用户“感测”设备并对其进行控制。 上升构件可以是可移动的和/或构造成偏向于与使用者接触。 公开了各种实施例。
