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.

Disclosed is a power-driven shoe. The shoe includes a shoe sole having a plurality of rotatable wheels arranged below the shoe sole in an overlapping fashion. The distance between the rotational axis of the wheels is less than or equal to the diameter of the wheel, such that vertical obstacles can be overcome in both the positive and negative displacement directions for increased ground stability. The shoe sole includes a toe part and a sole part that are connected to each other, via a hinge, in both a rotational and translational configuration, such that at least one front wheel or at least one middle wheel are independently in contact with the ground while maintaining at least one rear wheel in contact with the ground throughout a bi-pedal gait cycle, allowing for comfort during a user's natural range of motion.

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.

Mobilized platforms are disclosed herein. The mobilized platforms can include one or more fork hangers attached to a platform with a cog-hub assembly attached thereto. The fork hangers can be attached to the cog-hub assemblies such that each fork hanger is attached to a cob-hub assembly at both a first cog-hub assembly end and a second cog-hub assembly end opposite said first cog-hub assembly end. The mobilized platforms can include additional features such as baseplates or transom plates. The cog-hub assemblies can also comprise wheel assemblies or connected cog-hub subassemblies. The mobilized platforms can also include a treading connected to the cog-hub assemblies.

An electric skateboard has a frame assembly that includes a deck with an opening of the deck to house a battery case mounted to a bottom of the deck. The frame includes a top plate that covers the opening and forms with the battery case an enclosure. A battery pack is positioned in at least partially in the enclosure. Front and a rear trucks are mounted to the bottom of the deck. At least one of the first and front and rear trunks is coupled to first and second wheels mounted on axles of the front and rear trucks. The front truck is mounted on the front end and a rear truck is mounted on rear end of the deck. First and second wheels are powered by one motor with a differential and a shaft coupled to the first and second wheel. The motor is coupled to the shaft to rotate the first and second wheels. The motor is electrically connected to the battery pack through a rear channel. The motor rotates the first and second wheels in the same directions and propels the electric skateboard forward and backward.

Disclosed is a self-balancing vehicle including a left housing assembly, a right housing assembly, a left wheel train, a right wheel train and a rotation mechanism. The left wheel train is connected with the left housing assembly. The first end of the rotation mechanism is connected with the right wheel train and the right housing assembly, and the second end of the rotation mechanism is inserted into the left housing assembly and rotationally connected with the left housing assembly. The rotation mechanism is just arranged in the right housing assembly, but connected with the right housing assembly and the right wheel train respectively, thus reducing the strength requirements of the self-balancing vehicle on the left housing assembly and simplifying the components of the left housing assembly.

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 subject of the invention is an in-line skate braking system designed to brake in-line skate wheels. This is achieved by an electric motor controlling the action of the brake segment on in-line skate wheels.
