Methods, devices and computer systems utilize ground penetrating radar (GPR) embedded in or mounted on a ski or other equipment that is in contact with the snow during use device in order to obtain snow profile data from layers of snow or ice. A GPR device may include a trained model capable of deriving snow profile information based on GPR data and may also be capable of uploading GPR data to an online service. The online service can use the received GPR data to derive snow profile information, distribute snow profile information to user devices, and generate and distribute updated trained models. The online service may access online repositories of additional information and refine the snow profile information or the trained model based on such addition information. Generated snow profile information can be used to provide avalanche risk assessments.

A device allowing the control of a pair of skis or a surfboard, in particular for snow, by the combined simple rotation and simple tilting of a single drive member such as a handlebar, simultaneously by lateral inclination and by longitudinal warping. It therefore combines the necessary mechanical functionalities of a pair of conventional fasteners with the ease of use of a bicycle and does not require skis or specific surfboard. It allows you to move freely over the snow by driving with both feet which are retained but not locked, or to use one foot to push on the flat and stabilize. The lever arm offered by the drive body is much greater than that of a pair of conventional fasteners, greatly improving the ease of use and the maximum capabilities of the machine. Finally, it instantly folds back for easy handling and storage.

An accessory holder includes a base portion configured to mount to a mounting surface. The accessory holder further includes an extension extending from the base portion and having a channel defined therein. The channel is configured to receive an accessory. The accessory may be a ski pole where the mounting surface is a snow sport equipment.

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 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.
