A self-balancing board is provided, comprising a platform having a first foot deck portion to substantially support a first foot of a rider, and a second foot deck portion to substantially support a second foot of the rider. A wheel assembly is positioned between the first foot deck portion and the second foot deck portion along a longitudinal axis of the platform, and comprises a wheel having a rotation axis that is generally orthogonal to the longitudinal axis of the platform, and a motor unit driving the wheel. An orientation sensor senses the orientation of the platform. A controller receives data from the orientation sensor and controls the motor unit in response to the received data. At least one suspension interface between the platform and the wheel assembly has a single degree of freedom generally orthogonal to the rotation axis of the wheel and to the longitudinal axis of the platform, and biases the platform towards a rest position.

An active footwear suspension system is disclosed. The footwear system provides dynamic suspension using at least one or more variable resistance beams. At least one or more VRB extends from a heel section and/or a front section to a force plate or platform section of the footwear, thus providing selectable suspension to the wearer. The selected rotation of the VRBs from a first position to a second position provides customized suspension between a minimum resistance to a maximum resistance per zone.

An active suspension orthotic support system is disclosed. The suspension orthotic support system comprises at least one variable resistance beam extending from a heel section to a mid-arch section of the footwear, wherein rotation of the variable resistance beam from a first position to a second position causes a resistance provided by the variable resistance beam to vary between a minimum resistance to a maximum resistance.

A shock absorbing device designed to be mounted to a sliding board, includes a mobile device connected to a mechanism transmitting the forces generated during the deformation of the board and including a part of a deformable viscoelastic material, such that the part is shaped in such a way that its transversal section varies longitudinally in an increasing and decreasing manner, to form hollows and ridges, wherein the distance between the hollows and/or the distance between the ridges varies during the deformation of the part.

A parkour wheeled boot for increasing moving speed, having self-balancing function, wearable on a respective leg of a user. Each boot has a wearing mechanism, a shock reduction mechanism, a drive mechanism, a motion transmission mechanism, a power mechanism and a control mechanism. The wearable mechanism has a pedal, a pedal fixation rack, calf supporting plates, and magnetic pieces or belt and buckle. The shock reduction mechanism has a spring seat, springs and a cover. The drive mechanism has a motor having a hollowed center, and also an inner wall of a bearing. The motion transmission mechanism has an outer wall of the bearing, a wheel hub, and a rubber tire. The power mechanism has batteries, battery smart protection control board, ports and connection wires. The control mechanism is a single board unit with microprocessor, angular speed sensor, acceleration sensor, pressure sensor and relevant electronic components.

A blade arrangement for an ice skate boot, the blade arrangement comprising a support for an ice skate boot with a blade runner mounted to the support and a suspension structure arranged between the support and the blade runner.

The present invention is related to a roller ski with an adapted shock absorber device arrangeable inside a hollow backend of the roller ski body (16), wherein a first member (11) of the shock absorber device is supporting a backend wheel of the roller ski, a second member (14) is attachable to an inside surface of the hollow backend of the roller ski body (16), wherein a material strip (13) of a stretchable and compressible material is arranged in between the first and second member (11, 14).

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.

The present invention provides a bidirectional energy-transfer system comprising: a thermally and/or electrically conductive concrete, disposed in a structural object; a location of energy supply or demand that is physically isolated from, but in thermodynamic and/or electromagnetic communication with, the thermally and/or electrically conductive concrete; and a means of transferring energy between the structural object and the location of energy supply or demand. The system can be a single node in a neural network. The thermally and/or electrically conductive concrete includes a conductive, shock-absorbing material, such as graphite. Preferred compositions are disclosed for the thermally and/or electrically conductive concrete. The bidirectional energy-transfer system may be present in a solar-energy collection system, a grade beam, an indoor radiant flooring system, a structural wall or ceiling, a bridge, a roadway, a driveway, a parking lot, a commercial aviation runway, a military runway, a grain silo, or pavers, for example.

Disclosed is a configurable modular damping ice-skating blade assembly including a frame with a blade runner extending along a longitudinal axis and being removably mounted in relation to the frame. The modular damping ice-skating blade assembly is configurable with the use of modified blade runners so as to allow one or more configurations for damping the frame in relation to the blade runner.
