Using Magnetic Flux Patents (Class 188/267)
  • Patent number: 11437903
    Abstract: Described herein are latching devices where relative speed of movement between members is in part controlled or reduced via eddy current formation and in part controlled or relative motion stopped via a latch arrangement. Various embodiments are described, one being use of a conductive member; at least one magnetic field and a latch member that, prior to latching, moves independently to the at least one conductive member. A kinematic relationship exists between the conductive member and at least one magnetic field that enables the conductive member to move at a different speed relative to the magnetic field on application of an energizing force, thereby inducing an eddy current drag force by relative movement of the conductive member in the magnetic field. The eddy current drag force resulting causes movement of the conductive member causing the conductive member to engage the latch member thereby halting movement between the at least one conductive member and the at least one latch member.

  • Patent number: 10974822
    Abstract: An anti-tail buffet device leverages existing rotorcraft components to attenuate a tailboom's lateral “ringing” from air buffeting. Anti-buffet masses are tuned to the tailboom's lateral-bending or torsional natural frequency such that when lateral motion occurs, the response at this frequency is cancelled by the anti-buffet system, preventing this vibration from entering into the tailboom structure. Motion stops prevent over-travel. The mass of the tail rotor actuator is soft-mounted, such that its natural frequency is equal to the tailboom's lateral-bending or torsional natural frequency. When lateral loading occurs on the tail rotor disk, the lateral response at this frequency is attenuated by the soft-mounted tail rotor actuator, thereby preventing the vibration in the tailboom structure.

  • Patent number: 10337134
    Abstract: A laundry device comprises an outer tub, an inner tub, an inner magnetic ring and an outer magnetic ring. One of the inner magnetic ring and the outer magnetic ring is directly or indirectly fixed on a bottom wall of the inner tub and positioned at the outer side of the bottom wall of the inner tub, and the other one is directly or indirectly fixed on a bottom wall of the outer tub and positioned at the inner side of the bottom wall of the outer tub. An upper end face and a lower end face of the inner magnetic ring have the same polarity as the upper end face and the lower end face of the outer magnetic ring so that a radial repulsion between the inner magnetic ring and the outer magnetic ring is used to suppress vibration of the inner tub and/or the outer tub.

  • Patent number: 10316450
    Abstract: A washing machine comprises: an outer drum; an inner drum rotatably disposed in the outer drum; and a rotation mechanism for driving the inner drum to rotate. A rotation shaft of the rotation mechanism extends upwardly from the bottom of the outer drum to a bottom wall of the inner drum to drive the inner drum to rotate. The washing machine further comprises: at least one pair of magnets including an outer ring-shaped magnet and an inner ring-shaped magnet which is disposed at a radial inner side of the outer ring-shaped magnet and opposite to the outer ring-shaped magnet. The inner ring-shaped magnet is disposed on the rotation shaft, and the outer ring-shaped magnet is disposed at the bottom wall of the inner drum or the outer drum, so that a magnetic force between them can reduce a magnitude of vibration of the inner drum or the outer drum.

  • Patent number: 10280663
    Abstract: An exemplary assembly includes a cylinder, a piston, and a lock. The lock is transitionable between an unlocked position that permits extension and retraction of the piston relative to the cylinder, and a locked position that limits retraction of the piston relative to the cylinder. The lock is blocked from transitioning from the locked to the unlocked position when a load supported by the piston exceeds a threshold load. An exemplary method includes transitioning a lock from an unlocked to a locked position. The lock in the unlocked position permits extension and retraction of a piston relative to a cylinder. The lock in the locked position limits retraction of the piston relative to the cylinder. The method further includes holding the lock in the locked position using a load supported by the piston that exceeds a threshold load.

  • Patent number: 10267373
    Abstract: To solve a problem, for example, in which holding a movable mass becomes difficult because the spring characteristics of a rubber constituting a basis are set low in order to set the characteristic value at a low value. In a first dynamic vibration absorber including a movable mass that is coupled to a vibration damping target member via an MRE as a first elastic member having elastic characteristics variable with a magnetic field, and being capable of varying a vibration characteristic value of the movable mass by controlling the magnetic field, the dynamic vibration absorber has a second elastic member different from the MRE, and the vibration damping target member and the movable mass are elastically-coupled to each other via the second elastic member.

  • Patent number: 10024379
    Abstract: A hydraulic shock absorber having an inner housing portion slidably coupled to an outer housing portion to define a variable size chamber for containing shock absorber fluid. The region where the inner and outer housing portions overlap defines an annulus between adjacent surfaces of the inner and outer housing portions which varies in size in accordance with the extension state of the shock absorber. A dynamic seal is coupled to a surface of the shock absorber within the annulus for confining shock absorber fluid to the chamber. The shock absorber fluid is an electro-rheological or magneto-rheological fluid and the shock absorber includes a device for generating a magnetic or electric control field within the chamber at a region adjacent dynamic seal in order to increase the viscosity of the shock absorber fluid adjacent to the dynamic seal to inhibit passage of the shock absorber fluid beyond the dynamic seal.
