A ski may define a body that defines a tip, a tail opposite the tip, a top sheet, a base extending from the tip to the tail and opposite the top sheet, a core layer positioned between the base and the top sheet, and a reinforcement layer positioned between the top sheet and the base. The reinforcement layer defines an aperture extending through the reinforcement layer and positioned within a first third of a length of the ski, the length defined from the tip to the tail.

A downhill snow ski sound system comprises a speaker coupled to a binding of a snowboard or ski. An orifice is located at a perimeter of the binding and a strap is coupled to and extends from the orifice. The speaker is releasably coupled to the binding by the strap. The speaker is positioned adjacent the binding with less than an inch between the speaker and the binding. The speaker is also positioned directly on and contacting the ski-board.

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.

A system for analysis of user gait and foot disorder intended to minimize risks ulceration and limb amputation associated with the uncontrolled increase of the foot temperature in persons with diabetes. This system comprises a motion, force and temperature sensors and a processing element configured to process motion algorithms, measure ground reaction force (GRF) and changes in foot temperature embedded in the footwear insoles in communication with a smartphone based analysis application using wireless radio interface. The analysis application processes data received from the footwear sensors, compares the results with set of criteria and rules, and if any of the predefined criteria is exceeded, provides alerts to the user and the remote medical supervisor. Additionally, the insoles may be equipped with a haptic actuators configured to determine the level of the user neuropathy by measuring vibration perception threshold (VPT) level.

A sports board apparatus includes a sports board and a sound module. The sports board includes a lower face for sliding and an upper face for supporting a user. The sound module is connected to the sports board, and includes a power supply and a circuit electrically connected to the power supply. The circuit comprises a vibration sensor, an audio controller electrically connected to the vibration sensor, and a speaker electrically connected to the audio controller. The audio controller actuates the speaker to provide sound like that from a vehicle in operation when the vibration sensor senses vibration.

A sporting equipment is disclosed. The sporting equipment may include a harness, and a protective plate. The protective plate may be integrally formed with the harness from a plurality of fibers that are continuous from the harness into the protective plate.

A system for analysis of use of a sliding board comprising at least one piezoelectric element configured to be secured to the sliding board and generate electric energy during deformations of the sliding board; and an electronic processing circuit configured for estimating at least one parameter of use of the sliding board and configured to be connected to the sliding board. The electronic processing circuit is powered by the electric energy generated by the at least one piezoelectric element.

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.

A method for the continuous ranking of a competitor during a race of a slalom skiing type sports discipline includes the following iterative steps: a step of measuring the variation in the lateral angle of the gliding board about a predefined axis, a step of detecting the moment when the angle passes through a predefined value, a step of recording the competitor's run time corresponding to the detected moment, a step of comparing the stored run time with those of the preceding competitors for the corresponding detected moment, and a step of ranking the competitor with respect to the preceding competitors as a function of the run time of each competitor. A ranking system implements the method.
