A system for analysis of user gait and foot disorder intended to minimize risks ulceration and limb amputation associated with the uncontrolled increase of the foot temperature in persons with diabetes. This system comprises a motion, force and temperature sensors and a processing element configured to process motion algorithms, measure ground reaction force (GRF) and changes in foot temperature embedded in the footwear insoles in communication with a smartphone based analysis application using wireless radio interface. The analysis application processes data received from the footwear sensors, compares the results with set of criteria and rules, and if any of the predefined criteria is exceeded, provides alerts to the user and the remote medical supervisor. Additionally, the insoles may be equipped with a haptic actuators configured to determine the level of the user neuropathy by measuring vibration perception threshold (VPT) level.

A caster board can include a front platform, a rear platform, and at least two neck sections extending between the front platform and the rear platform. The neck sections can serve as a torsion element allowing twisting of the front platform relative to the rear platform. An aperture between the neck sections can be configured to receive an insert. The insert can alter a structural characteristic of the caster board, such as the torsional stiffness of the caster board.

A flyboard comprising a base element and an upper element in communication with each other by magnetic fields having the same polarity and magnetic fields having opposite polarities to permit floatation of the upper element over the lower element while a user is standing on the upper element.

Continuous or discontinuous steering responses for a lean-to-steer device can be provided by controlling the steering angle of at least one wheel by a steering motor that is operated by a controller. The controller receives signals from a tilt sensor to calculate an appropriate steering angle for the at least one wheel. When a speed sensor is also provided, the controller can calculate a steering angle to match the curve radius of motion to the pendulum angle corresponding to the indicated speed and tilt.

The subject of the invention is an in-line skate braking system designed to brake in-line skate wheels. This is achieved by an electric motor controlling the action of the brake segment on in-line skate wheels.

The present invention relates to motorized platforms wearable by a user, for enhancing the speed of walking while maintaining stability and reducing overall weight, due to a simplified structure and relatively modest number of components.

A sport board system is provided, the system having a sport board deck having a bottom surface, a front end and a rear end, a rear wheel assembly fixed to the bottom surface adjacent the rear end, and a fixation structure for a wheel assembly at the front end. The fixation structure has a notch passing through a thickness of the sport board deck, fixation rails parallel to a length of the sport board deck, and a locking mechanism at an end of the notch. Also provided is a method for transforming a sport board system from a skateboard configuration to a scooter configuration.

A system for analysis of the performance in use of a sliding board includes a database storing baseline performance; a sensor sensitive to the deformations of said sliding board; and a monitoring body. The monitoring body determines the performance in use based on measurements from the sensor; and compares the performance in use with the baseline performance. The sensor is secured to the sliding board and has at least one piezoelectric element secured to the sliding board and configured to generate electric energy during the deformations of the sliding board; and an electronic processing circuit, powered exclusively by the electric energy generated by the at least one piezoelectric element.

A device for setting the orientation of a boot binding on a snowboard includes a disk fixable to the board, the binding being mounted to be able to rotate in relation to the disk about a vertical axis of rotation, at least one locking method mounted adjustably between a locked position where it immobilizes the binding in relation to the disk, and an unlocked position where it allows the rotation of the binding around the axis of rotation for an angular adjustment of the binding in relation to the board, the displacement of the locking method is ensured by an actuator, that is remotely controllable, and a locking method and an actuator that are installed in the disk so that: the actuator can be actuated when the boot is retained in the binding and, the locking method is movable by the actuator when the boot is retained in the binding.

A motorized vehicle assembly includes an axle comprising a channel extending along a central axis of the axle, a socket positioned within the channel of the axle, and a motorized wheel configured to be mounted on an end the axle. The motorized wheel includes a boss configured to engage the end of the axle when the motorized wheel is mounted on the axle, an electric motor, a tire mounted on the rotor, and a plug positioned within the boss, the plug configured to engage with the socket when the motorized wheel is mounted on the axle. The electric motor includes a stator fixed to the boss and a rotor surrounding the stator, the rotor configured to rotate relative to the stator. The electric motor is configured to cause the rotor to rotate relative to the stator to cause the tire to rotate.
