A remote access system for ski equipment rental with remote multi-factor authentication ski binding release settings (DINS), calculation, verification and acknowledgement. An integral server connected lockable device interlink application provides for remote rental and binding visual release indicator setting resolved with user verification for access. Skier informational input via remote app is required for binding DIN setting by a qualified technician before placement in the server connected lockable device. Remote verification of visual release indicator setting (DINS) and acknowledgement by the skier is required before release from the server connected lockable device by a server-based recognition and authentication application software, such as a smart locker with a mobile and/or web application for skier information required for a multi-factor authentication ski binding release settings (DINS), calculation, verification and acknowledgement to release ski equipment from connected smart lockers or similar device.

An apparatus for automatically adjusting tension on retention member to hold multiple objects together. Examples include using retention apparatus to obtain optimal fit and use of a human wearable item such as article of footwear. Sensors may be used to sense changes in movement of the article of footwear, of the person wearing it, or of a third object such as a vehicle carrying the person. A retention member may surround at least a portion of the objects, and an actuator may be included that automatically rotates a rotating member such as a gear or pulley that may be coupled to the retention member. The rotating member may be configured to automatically adjust tension on the retention member many times per second based on control signals from control logic responsive to the sensors.

Novel side rails for self-stabilizing, one-wheeled electric skateboards and related products are disclosed. The angled frame rails of this invention and disclosure lower the center of gravity at the contact points—i.e. a rider's feet on the footpads—by as much as possible without losing any clearance at the front and rear bumpers, and tilt the gyroscope to change the zero-degree level default position. In order to achieve this, the inventive rails herein change to a downward tilt as soon as possible after the axle bolt connection points, then tilt back up before the footpad decks and continue through the front and rear of the vehicle. In one embodiment, a five-degree downward tilt of the rails allows for an approximately one-half inch drop in the center of gravity of the vehicle, thus increasing speed, stability, and safety.

Various implementations include a skateboard truck including a baseplate, a hanger, and a kingpin. The baseplate defines has a mounting surface. The hanger includes a main portion, a pivot pin, a first branch, and a second branch. The pivot pin is disposed within a pivot cup of the baseplate. The kingpin is disposed within openings in the baseplate and hanger. The branches each have curved longitudinal axes, a first portion coupled to the main portion, and a middle portion coupling the first and second portions. The second portion of each of the branches defines an axle opening. The first portion extends from the main portion toward the middle portion in a direction away from a mounting surface plane. The second portion extends from the middle portion in a direction toward the mounting surface plane. The first portions are closer to each other than the second portions are to each other.

Methods and systems are provided for concave footpads for a personal transport device. In one example, the concave footpads may be coupled to the personal transport device, arranged between an operator's feet and an upper surface of the personal transport device, the upper surface including a pressure transducer.

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 system for adjusting physical properties of a ski or snowboard, through use of one or more specially shaped components applied upon or embedded within the ski or snowboard, wherein the components may be comprised of a thermally responsive material that includes nitinol, and wherein the nitinol components may themselves be treated using a specific method in order to achieve desired transformation results that adjust stiffness, rocker, and in some cases camber angle of a ski.

A self-balancing vehicle includes a vehicle body having a housing with left and right sides which are independently moveable. A unitary support bar is disposed within the housing, and a left drive wheel and an opposed right drive wheel are each coupled to the support bar. A bracket encircles the support bar; the bracket has a cylindrical body formed with a slot through the body. A set screw is fixed to the support bar and is received within the slot to limit rotational movement of the support bar with respect to the bracket.

The present invention relates to a drifting electric scooter and, more specifically, to a drifting electric scooter, wherein: a sensor unit is installed at a controller and the movement of a scooter is controlled according to the moving direction and angle of the controller, and thus a short control section for acceleration and stopping of a conventional electric scooter is widened, so that the problems, such as abrupt start and abrupt stop, of the conventional electric scooter can be solved; the drifting electric scooter allows riders to more precisely control the speed and enjoy riding such that the riders can easily and safely control acceleration and stopping by simple upward/downward movement of the controller; a human body detection sensor is attached to a handle portion of the controller, and thus the scooter stops to prevent malfunction of the scooter when the controller is separated from a user's hand, so that safety is ensured and thus safe riding is possible; and multiple switches for selecting various riding modes are installed at the controller, so that more pleasant and interesting riding than in conventional scooter riding is possible.
