A snowboard and/or ski jumping structure configured to be run along a riding direction and made with snow of a ski area; the snowboard and/or ski jumping structure comprising a ramp, in particular made with snow of the ski area, which comprises a transition zone and a take-off zone, wherein the take-off zone is characterized by a take-off angle at a take-off point of the take-off zone; and a landing zone, particularly made with snow of the ski area, comprising a first zone, such as a sweet-spot zone, and a second zone, such as a critical zone; wherein the sweet-spot zone has variable slopes along the riding direction.

A roller board has axles provided with castors and secured at the front and rear ends of a board deck such that a steering movement is transferrable to the axles by a person on the board deck by lateral shifting of weight. Steerability and problem-free operation are improved. Substantially rigid booms, one directed to the front and one directed to the rear, are provided at the front and rear ends of the board deck, respectively. A support arm pointing in the direction of the central axis of the board deck is rigidly fastened to each boom. The support arms are pivotable on the two sides about a pivot axis inclined in the direction of travel by 40° to 50° relative to the plane of the board deck. The axle of a single castor is mounted rotatably in or on each hub, with the pivot joint inside the castor.

Various implementations include a wheel hub configured to be used with an electric vehicle. The wheel hub includes a hollow cylindrical body, a direct drive motor, a hollow axle, a battery, and a tire. The hollow cylindrical body includes a first end surface and a second end surface that is axially opposite and spaced apart from the first end surface. The direct drive motor is disposed within the hollow cylindrical body and is configured to rotate the cylindrical body about a central axis of the motor. The hollow axle has a central axis that is coaxial with the motor central axis and is at least partially disposed within the cylindrical body. The battery is disposed within the hollow cylindrical body and is in electrical communication with the direct drive motor. The tire is fixedly coupled and disposed on an external surface of the hollow cylindrical body.

Fender assemblies are disclosed, each including a rectangular frame defining a central aperture. The perimeter of the central aperture may have a rounded-rectangle shape. A fender arch in the form of an arcuate sheet, e.g., of carbon fiber (CF), terminates on either end at respective first and second flanges extending outward to form a planar base. The arcuate sheet extends through the central aperture to reach above a top side of the frame and the flanges abut a bottom side of the frame. A mud guard is coupled to the rectangular frame through the first flange of the arcuate sheet, such that the mud guard extends from the first flange away from the second side of the frame. The frame and mud guard may be made of plastic, and may be configured to absorb assembly forces to avoid damaging the CF fender arch.

Various implementations include approaches for training a surface detection classifier and detecting characteristics of a surface, along with related micromobility vehicles. Certain implementations include a method including: comparing: i) detected movement of a micromobility (MM) vehicle or a device located with a user at the MM vehicle while operating the MM vehicle, with ii) a surface detection classifier for the MM vehicle; and in response to detecting that the MM vehicle is traveling on a restricted surface type for a threshold period, performing at least one of: a) notifying an operator of the MM vehicle about the travel on the restricted surface type, b) outputting a warning at an interface connected with the MM vehicle or the device, c) limiting a speed of the MM vehicle, or d) disabling operation of the MM vehicle.

Disclosed is a wearable apparatus configured for monitoring a user's environment and items in a user's environment. The wearable apparatus comprises a plurality of communication circuits configured to communicate using a plurality of communication protocols. The wearable device is configured to use sensors to automatically detect organisms in a user's environment and issue and warnings related to a detected organism. The wearable device is configured to communicate with a plurality of health sensors that may be separate modules using a plurality of communication protocols and combine the health reading into user health status data. The user status data may be transmitted along with verification tags to remote devices.

A system for analysis of user gait and to provide correction in form of haptic and visual feedback. This system comprises a motion and force sensors and a haptic actuator embedded in the user shoe insoles in communication with a smart-phone based analysis application, configured to calculate motion and orientation of the user feet in relation to the value, location and distribution of ground reaction forces measured by sensors located in the shoe insoles and after analysis of said forces and motion, to provide haptic feedback to the user foot instructing about the location (and timing) of pressure the user must apply to achieve an optimal gait.

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.
