An apparatus, system and method for ski training are disclosed herein for providing feedback to a skier regarding the orientation of their skis. The apparatus, system and method measure various distances between a first ski and a second ski, determine an angle between the first ski and the second ski based on information representative of various distances; and provide an indication of the measured angle.

The present disclosure comprises a novel system that attaches to skis in an alpine touring setup and provides electric, battery powered, motorized traction that assists the skier when traveling uphill or horizontal on snow. In one embodiment, the devices removably attach to the ski near the tail and have a cylindrical traction surface that sits below the ski near the tail. The traction surface is powered by an electric hub motor which engages, either with initiation of forward movement, input from sensors, or a set programmed cadence, thereby assisting the user's moving, unweighted ski forward until the completion of that step. Once arrived at the desired destination, or when downhill travel is warranted, the user removes and stores the devices from each ski and proceeds downhill.

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 ski winter sports device for sliding down a hill. The ski winter sports device includes a first ski, a second ski and a third ski, a standing device on which a user can stand, a holding device, and a frame. The first and second skis are arrangeable on the standing device next to each other in a direction of travel so that the first ski is available for a first foot of the user and the second ski is available for a second foot of the user. The holding device can be held by at least one hand of the user. The frame connects the standing device to the holding device. The frame is connected to the standing device in a relatively movable manner. The frame and the standing device are foldable relative to each other so that a spatial volume of the ski winter sports device is reducible.

A user controlled power assisted device to automate snowboard and wideboard recreational snow devices to make turning easier and more consistent for the user, while viewing the line of travel straight ahead instead of the conventional sideways view.

The user simply presses one foot or the other down to enable the proper edging to effect the desired turn. The user's foot pressing rotates the control shaft, which electronically communicates via the pot, motor controller, battery, and motor. The motor then proportionally rotates the drive shaft accordingly to rotate the device longitudinally which provides proper edging to effect the desired turn. The motor rotates around the control shaft to reduce torque backpressure on the board.

A portable snowboard with detachable parts comprises a first planar section and a second planar section. The first planar section comprises a first member of an interconnecting joint. A second end of the first planar section comprises the first member of the interconnecting joint. The second planar section comprises a second member of the interconnecting joint. The second end of the second planar section comprises a second member of the interconnecting joint. The first member of the interconnecting joint is detachably fastened to the second member of the interconnecting joint to engage the first planar section with the second planar section to form the portable snowboard.

Embodiments of the present disclosure provide a sled having a sled attachment and a runner. The sled attachment may include a control deck and a connector assembly coupled to and positioned below the control deck. The runner may be coupled to the connector assembly and spaced apart from the deck. The runner may extend along a longitudinal axis of the control deck. The runner may comprise a snowboard.

A non-motorized transport device including first and second skis; first front and rear fastening feet fastened on the first ski and second front and rear fastening feet fastened on the second ski; a longitudinal beam; an edging handle fastened to the longitudinal beam; and a connecting system connecting the longitudinal beam to the first and second front and rear fastening feet, the connecting system including first and second front connecting rods each including a middle portion pivotally mounted on the longitudinal beam about a respective front articulation axis and first and second end portions which are respectively connected to the first and second front fastening feet by respective front ball joint connections, and a rear connecting rod including a middle portion pivotally mounted on the longitudinal beam about a rear articulation axis and first and second end portions respectively connected to the first and second rear fastening feet by respective rear ball joint connections.
