  • Patent number: 9576853
    Abstract: A magnetic trap is configured to arrange at least one diamagnetic rod. The magnetic trap includes first and second magnets on a substrate that forms the magnetic trap defining a template configured to self-assemble diamagnetic material. Each of the first and second magnets extends along a longitudinal direction to define a magnet length, and contact each other to define a contact line. The first magnet and the second magnet have a diametric magnetization in a direction perpendicular to the contact line and the longitudinal direction so as to generate a longitudinal energy potential that traps the diamagnetic rod along the longitudinal direction.

  • Patent number: 8665042
    Abstract: A wireless switch comprises a mechanical oscillator, a mechanical impulse deliverer, a first array of magnets positioned on a planar surface, a first conductor, and a power management circuit. The mechanical impulse deliverer delivers a mechanical impulse to the mechanical oscillator when the wireless switch is switched. The first array comprises a one dimensional or two dimensional array of magnets. The first conductor comprises a first serpentine conductor. The power management circuit provides DC power as a result of relative motion due to the mechanical oscillator between the first array of magnets and the first conductor.

  • Publication number: 20140055069
    Abstract: Two magnetic poles of a permanent magnet of a permanent magnet switch and the two ends of an iron core wound with an excitation coil are connected to each other with the soft magnet having a salient pole. A motor uses the switch as the basic component of the stator and rotor, with two magnetic salient poles of each component being arranged axially, wherein the salient pole of the stator component and that of the rotor component are arranged in an opposite manner with an air gap, the excitation coil of the stator component and the rotor component at the symmetric axis position is taken as a phase line to access an excitation control power supply after serial connection or parallel connection. Electric excitation is carried out on the combined motor formed by shaft connection and rotation dislocation among single motors and the stator component in a bi-phase way simultaneously.

  • Patent number: 8648720
    Abstract: Improved, magnetic high security switch apparatus is provided for use in detecting relative movement between first and second members such as a door frame and door from a close position, wherein the members are proximal, and an open position, where the members are separated. The switch apparatus includes a magnetic shiftable ball switch assembly having an elongated housing and a shiftable ball therein, which traverses an oblique path of travel between respective switch states in response to relative movement between the first and second members. Preferably, the housing is oriented at an oblique angle relative to the horizontal in order to prevent defeat of the switch apparatus through use of an external defeat magnet.

  • Patent number: 8638185
    Abstract: A magnetically-sensitive switch includes a housing, a metal block, a sling block, a rigid link, a first plate and an electrical switch. The housing includes a top wall, a bottom wall and two opposite sidewalls. A pair of sliding grooves is defined in the opposite sidewalls. The metal block is placed on the bottom wall. The sliding block is slidably connected to the sliding grooves. The rigid link is pivotally interconnected between the metal block and the sliding block. The first plate is attached to the housing. When the metal block is attracted by a magnetic force generated by a magnet placed adjacent to the top wall. The metal block is movable adjacent to the top wall, thereby driving the rigid link to drive the sliding block to slide towards the side opening along the sliding grooves until the sliding block triggers the electrical switch to generate a switching signal.

  • Patent number: 8593241
    Abstract: An enclosed proximity switch assembly includes a top enclosure and a bottom enclosure that are coupled to form an interior volume. A shaft protrusion upwardly extends from a top surface of the top enclosure, and an interior bore portion having an enclosed volume is defined within the shaft protrusion to form a portion of the interior volume. A first end of a vertical shaft is rotatably disposed within the interior bore portion such that the shaft rotates relative to the top and bottom enclosures. A samarium cobalt target magnet is coupled to the shaft, and the target magnet interacts with a samarium cobalt driver magnet within a proximity switch when the target magnet is rotated within a predetermined distance of a top portion of the proximity switch. The interaction causes a switch to move from a first state to a second state, or vice versa.

  • Publication number: 20130300524
    Abstract: Magnetic switches are disclosed herein. An example apparatus includes a mount and a switch actuator assembly coupled to the mount. The switch actuator assembly includes a body, a trigger, and a first magnet oriented to be attracted to a second magnet. Movement of the body from a first position to a second position is to cause relative movement between the first magnet and the second magnet and relative movement between the trigger and a switch.

  • Patent number: 8570130
    Abstract: A multilevel magnetic system described herein includes first and second magnetic structures that produce a net force that transitions from an attract force to a repel force as a separation distance between the first and second magnetic structures increases. The multi-level magnetic system is configured to maintain a minimum separation distance between a transition distance where the net force is zero and a separation distance at which a peak repel force is produced.
