摘要： A skateboard includes a motorized drive assembly and a motorized brake assembly, both operable with a wireless remote control to be carried by a rider. The drive assembly is free-wheeling permitting normal use of the skateboard in the event of battery depletion. The brake system includes a motor operable through a simple machine structure to move a brake pad against a brake disk mounted against a wheel. A self-adjustment mechanism presets the brake pad a predetermined distance from the disk prior to brake application. Motor enertia is relied on to store potential energy in a wheel axel in accordance with an associated method of operation.

摘要： A system for distributing fluid to a plurality of wellbores drilled from a common pad includes at least two fluid conduits extending between the wellbores. The fluid conduits are configured to couple at one end to a fluid pump. At least one remotely operable valve is hydraulically connected to each fluid conduit proximate each wellbore. At least one flow line hydraulically connects each remotely operable valve to each wellbore such that fluid moved through the flow line enters the wellbore. A control unit is disposed proximate the pad and is configured to operate the remotely operable valves.
