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.

According to an aspect of some embodiments of the present invention there is provided a driving unit for an in-line skate system having roller wheels, the driving unit has a motor configured to generate a driving power, a transmission gear coupled to the motor, and a transmission belt interconnecting the transmission gear and the two or more roller wheels to transfer the driving power to the roller wheel. According to an aspect of some embodiments of the present invention there is provided an in-line skate system, comprising one or more in-line skates and a driving unit.

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 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.

An electronically controlled detachable motorized track system for a snowboard having front and rear baseplates sized to fit in a backpack with right and left motorized tracks having a length extending beyond the front and rear baseplates from proximate the rear of a snowboard to proximate the front of a snowboard and beyond the front and rear baseplates, each adapted for wrapping around drive rollers and freely rotating rear rollers. A hand controller wirelessly controls the tracks.

A stowable motorized skateboard comprising a first board section, a second board section, a power supply section, and support bars. The first board section includes a locking mechanism and first support anchors. The second board section includes a controller, a motor, second support anchors, and power supply anchors. The power supply section is between the first and second board sections, encasing a battery electrically coupled to the controller and the motor, and including a catch receiving the locking mechanism. The power supply section further receives the power supply anchors. The support bars extend from the first board section to the second board section and receive the first support anchors and the second support anchors.

An electronically controlled detachable motorized track system for a snowboard having front and rear baseplates sized to fit in a backpack with right and left motorized tracks having a length extending beyond the front and rear baseplates from proximate the rear of a snowboard to proximate the front of a snowboard and beyond the front and rear baseplates, each adapted for wrapping around drive rollers and freely rotating rear rollers. A hand controller wirelessly controls the tracks.

An electric skateboard includes a frame assembly has a deck with an opening of the deck to house a battery case mounted to a bottom of the deck. The frame has a top plate that covers the opening and forms with the battery case an enclosure. A battery pack is positioned at least partially in the enclosure. Front and a rear truck are mounted to the bottom of the deck. At least one of the first and front and rear trunks are coupled to first and second wheels mounted on axles of the front and rear trucks. The front truck is mounted on the front end and a rear truck mounted on a rear end of the deck. Upper and lower control arms share a single shaft.

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.

Articles of clothing include modules for sensing physical and/or physiological characteristics associated with use of the clothing or for performing other functions. Such clothing systems and methods may use physical or other interaction(s) between the module and the article of clothing for activating and/or deactivating the module and/or sensing devices included with the module, for example, to confirm whether the module and clothing are authorized for use with one another, and/or for automatic data algorithm selection methods. Additionally, such systems may sense interactions between the module and a module securing element of the clothing to activate or deactivate functions of the module.
