A sport-boot pressure monitoring system and method of use. The system includes a left boot sensor having a left flexible fluid-containing bladder shaped to fit between a user's left leg and an interior surface of a left boot worn by the user and a left pressure sense element in pressure-sensing communication with the left flexible fluid-containing bladder, a right boot sensor that is similar to the left one, and a controller to provide a pressure alert if pressure between one of the user's legs and the interior surface of the boot worn on that leg violates a predetermined pressure threshold and to provide a proximity alert if a distance between the left and right boots violates a predetermined proximity threshold.

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 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.

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 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.

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 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.
