A support assembly for use with snow sports boards includes a base configured to be attached to the snow sports board. A frame has a first portion extending downward and a second portion extending rearward from the first portion. A seat is mounted on the second portion of the frame. A shock absorber extends between the base and the first portion of the frame. During use, the support assembly is configured to support a rider sitting on the seat in a face-forward position with the rider's knees vertically below and forward of the rider's hips.

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.

Disclosed is a support and suspension assembly for a snow sports board. The assembly includes a base configured to be attached to a snow sports board and a frame above the base. The frame includes a first portion extending vertically upward or upward and forward to an upper end. The frame further includes a second portion extending generally rearward from the upper end of the first portion. A seat is on the second portion of the frame. A shock absorber is connected between the base and the frame. A linkage assembly is pivotably connected between the base and the first portion of the frame.

A recreational and/or sports type transport (board) having an object detection and proximity warning system. The board uses sensors and calculates the distance from object, and then warns the user of the proximity of same through tactile and/or audio feedback.

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.

An exoskeleton system having an actuator unit configured to be coupled to a leg of a user. The actuator unit includes an upper arm and a lower arm that are rotatably coupled via a joint, the joint positioned at a knee of the user with the upper arm coupled about an upper leg portion of the user above the knee and with the lower arm coupled about a lower leg portion of the user below the knee; a fluidic actuator that extends between the upper arm and lower arm; and one or more fluid lines coupled to the fluidic actuator to introduce fluid to the fluidic actuator that causes force to be applied to the upper arm and lower arm.

A method of operating an exoskeleton system that includes obtaining a first set of sensor data from one or more sensors associated with one or more leg actuator units of an exoskeleton system during a user activity, the first set of sensor data indicating a first configuration state of the one or more actuator units; determining, based at least in part on the first set of obtained sensor data, to change configuration of the one or more leg actuator units to a second configuration state to support a user during the user activity; and introducing fluid to one or more fluidic actuators of the one or more leg actuator units to generate the second configuration state by causing the one or more fluidic actuators to apply force at the one or more actuator units.
