A braking mechanism of a wheeled device is provided, including: a main body, configured to be connected to the wheeled device including at least one wheel; an adjusting member, disposed on the main body and including a rod and a first abutting member adjustably positioned on the rod; a braking member, movably disposed on the main body; and an elastic member, abutted between the first abutting member and the braking member so that the braking member is biased by the force of the elastic member toward the at least one wheel to frictionally contact the at least one wheel.

A roller for a skating device comprising a first material having a minimum elastic modulus of 1 GPa, preferably at least 2 GPa, and more preferably at least 2.9 GPa and/or the maximum elastic modulus of the first material having 10 GPa, preferably at most 5 GPa, and more preferably at most 3.1 GPa.

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.

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 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.
