A passive heave compensator having: a main hydraulic cylinder, including a moveable piston having a piston rod extendible through the main hydraulic cylinder and a piston head to divide the main hydraulic cylinder between a gas phase above the piston head, and oil phase below the piston head; an upper connection point associated with the main hydraulic cylinder and a lower connection point associated with the piston rod; and an accumulator having a moveable separator to divide the accumulator between a gas phase above the separator, and an oil phase below the separator and being in communication with the oil phase in the main hydraulic cylinder; wherein an oil phase includes a magnetorheological substance, and that the passive heave compensator includes one or more electromagnetic controllers. In this way, operation of the one or more electromagnetic controllers can magnetize the magnetorheological substance to vary the viscosity of the oil phase, thus changing the degree of damping that can be provided by the passive heave compensator.

In a window covering system and a window covering control apparatus thereof, the window covering control apparatus comprises a driving module, a damping output module, and a damping control module. The damping output module and the driving module are configured to operate simultaneously. The driving module may drive the damping output module to provide damping to the driving module. The damping control module comprises a control detecting unit and a fitting unit. The control detecting unit comprises a detecting portion and a stopper portion, which are detachably engaged. During an expansion of a covering material, the driving module drives the damping output module to provide damping to the driving module; when the stopper portion is driven apart by the detecting portion from the fitting unit, the driving module operates independently of the damping output module to stop the damping output module from providing damping.

A balancing weight (10;20;30;40;51,52,53;60;70;71) for balancing a wheel of a vehicle has a body of non-ferromagnetic material providing a major portion of the balancing weight's mass and a ferromagnetic inlay (14,15;54,55,56;65;75) for holding the balancing weight by magnetic force. The ferromagnetic inlay provides a minor portion of the balancing weight's mass. A weight applicator (80) has a magnet (82) for interacting with the ferromagnetic inlay of the balancing weight and holding the balancing weight.

An energy storage system comprises a housing and a flywheel having a drive shaft portion attached to a cylindrical ferromagnetic rotor portion. The drive shaft portion defines a substantially vertical axis about which the rotor portion is mounted for rotation. A magnetic bearing assembly comprised of an annular permanent magnet having no electromagnetic components is mounted on the housing in stationary centered relation about the vertical axis above the rotor portion so as to attract the rotor portion axially upwardly towards a lower face of permanent magnet, thereby supporting a significantly high portion of the weight of the flywheel. At least one low friction mechanical bearing assembly is mounted within the housing about the drive shaft portion to provide radial positioning of the rotor portion and to limit at least upward axial movement of the rotor portion in relation to the lower face. The annular permanent magnet overlies a portion of the end face of the rotor with the balance providing a return path for magnetic flux.

A device and method for efficiently rotating a rotating body in a layer structure consisting of a plurality of rotating plates arranged in layers and intends to provide a device for and method of rotation capable of efficiently converting sequentially input rotative driving power into the rotational energy of the whole of the rotating body in a layer structure. A rotating device of this invention comprises a layered rotating body composed of a plurality of rotating plates (11 to 17) arranged in layers with distances therebetween and their rotating axes (3) aligned, in which, on each of said layered rotating plates (11 to 17) of the rotating body, groups of magnetic poles (31 to 37) are provided on the respective surfaces of the plates facing neighboring layers, said groups of magnetic poles (31 to 37) are made equal in polarity to those (31 to 37) on the opposing rotating plate (11 to 17) surfaces in the neighboring layers, and each magnetic pole in said groups (31 to 37) is arranged so as to be alternately opposite in the rotational direction to each one in groups (31 to 37) on opposing plates (11 to 17) in neighboring layers. Such a rotating device as above can be used as for example, a flywheel energy storage system when the rotating plates are used as flywheel disks and rotated at high speed to store rotational energy of the flywheel disks.
