The disclosure relates to a skateboard and control method thereof. A skateboard deck is fixed on an axle of the skateboard, and a first sensor group and a second sensor group are sequentially arranged on the skateboard deck in a width direction. The method includes acquiring a first pressure value of the first sensor group and a second pressure value of the second sensor group; controlling the skateboard to turn to a first direction when the first pressure value is greater than the second pressure value and a difference value between the first pressure value and the second pressure value is greater than a first threshold, and controlling the skateboard to turn to a second direction when the second pressure value is greater than the first pressure value and a difference value between the second pressure value and the first pressure value is greater than a second threshold.

According to an embodiment, a wheeled vehicle is provided, which includes a frame supporting a rear wheel, a rider's deck, and a steering post lying parallel to a longitudinal axis of the vehicle. A front axle is coupled to the frame and configure to rotate about the steering post while remaining perpendicular to the longitudinal axis. Axle stubs are coupled to respective ends of the axle so as to be pivotable relative to the axle, and front wheels are rotatably coupled to the axle stubs. A steering mechanism is configured to permit a rider to steer the vehicle by leaning on the rider's deck.

A self-balancing board is provided, comprising a primary wheel assembly, a platform, at least one sensor, a controller, a first auxiliary wheel assembly, and a first brake element. The primary wheel assembly comprises a primary wheel and a motor driving the primary wheel. The platform is secured to the primary wheel assembly and has a foot deck. The at least one sensor senses the orientation of the platform. The controller receives data from the at least one sensor and controls the motor in response to the received data. The first auxiliary wheel assembly is secured to the platform distal the primary wheel assembly, and is elevated from contacting a flat surface upon which the primary wheel rests when the foot deck is parallel to the flat surface. The first brake element is manually movable relative to the first auxiliary wheel assembly to engage the first auxiliary wheel assembly to provide resistance to rotation of the first auxiliary wheel assembly.

Devices and methods of transport are disclosed. Various embodiments include structural aspects related to steering and changing the direction of conveyances including features which utilize leaning or shifting of weight as part of turning.

A roller ski adapter system is disclosed. Said roller ski adapter system comprises a ski adapters, a skis, a poles and a brake lines. Said ski adapters comprises a front adapters and a rear adapters. Said poles comprises a shaft, a brake lever assembly, a first end, a second end and a grip. Said brake lever assembly comprises said brake lines, a lever and a cable guide. Said front adapters comprises a squeeze plate assembly, a trucks and a wheels. Said rear adapters comprises a braking system, a rear wheel assembly, a squeeze plate assembly, a trucks and a wheels. Said braking system comprises a braking bar, a brake line, a one or more spring assemblies, a splitter and a brake lines. Said one or more spring assemblies comprises a first end, a second end, a first bracket, a second bracket and a one or more braking bar fasteners.

Systems and methods for intelligent data center power management and energy market disaster recovery comprised of data collection layer, analytics/automation/actions layer, energy markets analysis layer. Plurality of data centers employ the systems and methods comprised of a plurality of Tier 2 data centers that may be running applications, virtual machines and physical computer systems to enable data center and application disaster recovery from utility energy market outages. Systems and methods may be employed to enable application load balancing and data center power load balancing across a plurality of data centers may lead to financial benefits when moving application and power loads from one data center location using power during peak energy hours to another data center location using power during off-peak hours.

A foot-deck-based vehicle, a front wheel support, and at least one accessory therefor are provided. The foot-deck-based vehicle has a foot-deck with a front end, a rear end, and at least one rear wheel proximal to the rear end. The foot-deck-based vehicle has a front wheel support comprising a pair of wheel interfaces, each of which is couplable to a front wheel, a main body extending between the wheel interfaces and coupled to the foot-deck, and at least one recess in the main body. At least one accessory is snugly securable within the at least one recess of the front wheel support to modify a resistance of the main body to bending under a bending load applied to the front wheel support through the foot-deck when the foot-deck supports a person.

A brake assembly for a longboard can include an anchor member coupled to a rear hanger member of a longboard, a brake lever member coupled to a brake pad, and a pedal assembly coupled to the brake lever member via at least one cable. The brake lever member can be pivotably coupled to the anchor member and movable between an applied position wherein the brake pad contacts a wheel of the longboard and an unapplied position. The pedal assembly can selectively move the brake lever between the applied position and the unapplied position when actuated by a user.

A bottom structure of a roller skate includes a sole; a frame secured to the sole and including front and rear supports and two hubs disposed on the front and rear supports respectively; a pivotal member disposed in the hub; two spaced sleeves disposed in the hub wherein the sleeves are further partially disposed in the pivotal member and secured to the pivotal member; a shaft passing through the hub, the pivotal member, and a gap between the sleeves, and rigidly secured to the pivotal member; and two enlargements disposed at two ends of the shaft respectively.
