A self-propelled, one-wheeled vehicle may include a board having two deck portions each having a concave front footpad configured to receive a foot of a rider, and a wheel assembly disposed between the deck portions. The concave front footpad has a rider detection sensor in the form of a membrane switch conforming to the shape of the footpad (e.g., facilitated by one or more slots formed in the membrane switch). A motor assembly drives the vehicle in response to board orientation and rider detection information.

A ski may define a body that defines a tip, a tail opposite the tip, a top sheet, a base extending from the tip to the tail and opposite the top sheet, a core layer positioned between the base and the top sheet, and a reinforcement layer positioned between the top sheet and the base. The reinforcement layer defines an aperture extending through the reinforcement layer and positioned within a first third of a length of the ski, the length defined from the tip to the tail.

A system for control of a mobility device comprising a controller for analyzing data from at least one sensor on the mobility device, wherein the data is used to determine the gait of user. The gait data is then used to provide motion command to an electric motor on the mobility device.

Presented is an apparatus and system for an artificial turf system. The artificial turf system includes a backing layer having a plurality of fibers extending therefrom. The artificial turf system further includes a plurality of impact sensors located at least partially on, in, and/or beneath the backing layer, wherein the plurality of impact sensors are operable to detect a force or pressure applied to the backing layer.

An apparatus for automatically adjusting tension on retention member to hold multiple objects together. Examples include using retention apparatus to obtain optimal fit and use of a human wearable item such as article of footwear. Sensors may be used to sense changes in movement of the article of footwear, of the person wearing it, or of a third object such as a vehicle carrying the person. A retention member may surround at least a portion of the objects, and an actuator may be included that automatically rotates a rotating member such as a gear or pulley that may be coupled to the retention member. The rotating member may be configured to automatically adjust tension on the retention member many times per second based on control signals from control logic responsive to the sensors.

An electric roller skate in the present invention includes a shoe body, a roller frame, a driver, a rotation speed detection device, and a controller. The controller receives rotation speed information of the rotation speed detection device and accordingly controls the driver to start to drive the rollers to rotate. The present invention further provides a control method for the electric roller skate described above. The controller is capable of controlling the driver to start to drive the electric roller skate to slide according to the detected rotation speed information. Through the above arrangement, the solution can help a user to skate in a more labor-saving manner and reduce fatigue of the user. Meanwhile, the driver is started in a mode closer to a conventional sliding mode, is higher in convenience and intelligence, reduces use difficulty and makes user experience better.

A stand-up wheeled vehicle may include an electrically powered wheel and a deck configured to limit a maximum value of an angle of declination of the deck in a forward direction of travel, for example, to less than about 20 degrees, 15 degrees, 10 degrees, or 8 degrees. The deck may be asymmetric, such that a length of a first portion of the deck between the wheel and a first end of the deck is greater than a length of a second portion of the deck between the wheel and a second end of the deck. The deck may include a first surface, an opposing second surface, and a chassis disposed in the second surface. The chassis may have a cavity formed therein configured to receive a stand-up wheeled vehicle. A coupling mechanism may be utilized to removably retain the stand-up wheeled vehicle in the cavity of the chassis.

A motor assembly for a transport vehicle (such as a skateboard) having at least one wheel for rotating about a shaft having an end distal to the wheel and an end proximal to the wheel, the motor assembly comprising a stator fixed to the shaft, and a motor bell surrounding the shaft at the location of the stator, wherein the motor bell comprises a first end being adapted to be attached to the wheel for transferring rotational movement of the motor bell to the wheel, and a second end surrounding the shaft at the location of the end distal to the wheel, wherein the second end of the motor bell is a free end permitting removal of the motor bell during removal of the wheel. The motor bell being adapted to permit airflow therethrough for cooling of the motor assembly.

Disclosed is a power-driven shoe. The shoe includes a shoe sole having a plurality of rotatable wheels arranged below the shoe sole in an overlapping fashion. The distance between the rotational axis of the wheels is less than or equal to the diameter of the wheel, such that vertical obstacles can be overcome in both the positive and negative displacement directions for increased ground stability. The shoe sole includes a toe part and a sole part that are connected to each other, via a hinge, in both a rotational and translational configuration, such that at least one front wheel or at least one middle wheel are independently in contact with the ground while maintaining at least one rear wheel in contact with the ground throughout a bi-pedal gait cycle, allowing for comfort during a user's natural range of motion.

A self-propelled, one-wheeled vehicle may include a suspension system configured to dampen up and down motion of a board relative to the axle of a central wheel assembly when the vehicle encounters obstacles and bumps on a riding surface. Illustrative suspension systems include a shock absorber, a rocker, a pushrod, bell cranks, and/or a swingarm that couple the axle to the board. The suspension system may be disposed completely below a foot deck of the vehicle.
