Some aspects include a ski binding system using controllable electromagnets, alone or in combination with permanent magnets, as means of attaching or releasing a ski boot to a ski during use. Some aspects include a ski binding system using a controllable solenoid. In some aspects, microprocessor-based control releases binding electronically based on input from sensors located in binding, ski and/or boot, as well as in other equipment or clothing connected to them or to skier, or binding releases when a mechanical threshold is overcome. In some aspects, sensor data are recorded for analysis of system performance and for adjustment and improvement of system parameters based on data analytics.

A blade measuring apparatus (21) to measure the radius and bend of skate blades along the longitudinal plane of the skate blade runner features a one-piece frame (1), thermally non-conductive handles (5), and adjustable, replaceable, and interchangeable magnetic force application components (9, 10) and assemblies.

An electric skateboard comprising: a deck; a front truck and a rear truck; a pair of wheels rotatably connected to each truck, wherein one or both pairs of wheels are driven by sensored motors; a communications module configured to receive control instructions from a wireless remote control and to transmit data to one or more external devices; a controller in communication with the communication module and the motors; and a battery supplying power to the motors, communications module and controller.

In an aspect, a powered vehicle is provided, and includes a body to support a rider. At least one wheel is rotatably coupled to the body to enable travel of the body over a travel surface. At least one motor is coupled to at least one of the at least one wheel to drive rotation thereof. A power source is coupled to the at least one motor to power the at least one motor. A remote sensor unit is wearable by the rider and configured to detect at least one of an orientation, a position, and movement of the rider and transmit sensor data generated therefrom. A motor control unit is coupled to the at least one motor and is configured to receive the sensor data and control the operation of the at least one motor based at least in part on the sensor data.

Mounts (10) for securing a device (12) to an article (14) comprise a housing (16) having an internal volume (18) configured to selectively receive and retain the device (12) in the housing (16); and a coupler (20) attached to the housing (16) and configured to be operatively attached to the article (14).

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.

An ice-skating measuring apparatus includes an ice-skate blade holder and an ice-skate blade. The blade holder has a front beam column and a rear beam column. The blade includes at least one sensor configured to measure forces acting on the blade, and the blade is detachable from the blade holder.

A personal conveyance including a flexible substrate, a wheel and an electric motor mounted to a first wheel assembly, the wheel rotatably supported by the first wheel assembly and the electric motor configured to drive the wheel, wherein the first wheel assembly is mounted to the flexible substrate, a battery mounted to the flexible substrate and configured to power the electric motor, and a processor configured to control operation of the electric motor.

The disclosure relates to a skateboard and control method thereof. A skateboard deck is fixed on an axle of the skateboard, and a first sensor group and a second sensor group are sequentially arranged on the skateboard deck in a width direction. The method includes acquiring a first pressure value of the first sensor group and a second pressure value of the second sensor group; controlling the skateboard to turn to a first direction when the first pressure value is greater than the second pressure value and a difference value between the first pressure value and the second pressure value is greater than a first threshold, and controlling the skateboard to turn to a second direction when the second pressure value is greater than the first pressure value and a difference value between the second pressure value and the first pressure value is greater than a second threshold.
