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 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 motorized or non-motorized multi-wheeled skateboard assembly including a board deck to support the user, a board having a top side, a bottom side, a flat and a rounded end, linkages, hinges, a steered wheel assembly, an input device and a drive assembly. The steered wheel assembly improves maneuverability, turn radius, and stability. The user steers the skateboard assembly by altering pressure between the top side first end and the top side second end causing the steered wheel to turn, thus manually steering the board. This change in pressure is also altered between the first linkage and second linkage in direct or inverse relation to altering pressure between the top side first end and the top side second end of the board deck.

A method and system for use in the game of football to determine ball placement and position, as well as first down demarcations, is described, with various embodiments configured to track the location of a football to determine its position on the field and to determine and display the first down demarcation on the field. Certain embodiments employ software to assist in performing placement determinations, distance determinations, track movement of the ball, first down markers, as well as light emitting modules along a track that extends parallel to the field.

An electric weight sensing skateboard using one or more strain gauge systems to detect rider-induced strain on one or both trucks, an inertial sensor to detect accelerations and balance position, and wheel speed sensors. Throttle is controlled by rider position, for example, lean forward to increase speed, lean back to slow down. Several drive methods include a driver position detection velocity setpoint control, torque setpoint control, and direct velocity/torque control. A throttle remote is note required. Rider weight activates the motors.

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.

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.

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.
