Embodiments herein are directed to a system and a method of selectively manipulating magnetically-barcoded materials from background magnetic materials. Magnetic barcodes include layers of magnetic anisotropy. These are then manipulated by a magnetic system that can drive spatio-temporal magnetic fields that can “match” a barcode to drive a specific interaction, thereby providing a “lock-key” interaction. This technique is able to selectively manipulate magnetically-barcoded materials, and can have applications across a variety of magnetic systems such as cell separation, drug delivery, valves, and motors.

The present disclosure is directed to a magnetic coupling system to improve stability at low magnetic docking forces, such as docking between a hand held device (102) and its base (104), where the hand held device and the base each contain a magnet (112, 108) with the same direction of polarity, arranged so that the two magnets attract each other when the hand held device is docked to the base. An auxiliary magnet (114) is included in the magnetic coupling system. In one example, the auxiliary magnet may be arranged within the hand held device at a predetermined distance from the other magnet within the hand held device and is arranged with polarity in the opposite directions as the other two magnets. In another example, the auxiliary magnet may be arranged within the base at a predetermined distance from the other magnet within the base and is arranged with polarity in the opposite direction as the other two magnets.

A device to attract and hold microscopic items such as micro LEDs magnetically rather than by static electricity includes a substrate and a plurality of magnetic units on a surface of the substrate. The magnetic units are spaced apart from each other and are constrained in the size and direction of their individual magnetic fields. Each of the magnetic units includes a magnet and a cladding layer partially covering the magnet. The cladding layer is made of a magnetic material. A side of the magnet away from the substrate is exposed from the cladding layer to attract and hold one micro LED.

A device for conveying a biological material includes a body including an aperture configured to enable connection with an outside of the body and a chamber configured to store a biological material, a plurality of conveyors accommodated in the body and configured to convey the material, and a driver configured to select one of the plurality of conveyors, align the selected conveyor with the aperture, and move the selected conveyor to the outside of the body through the aperture.

An embodiment of a barrier assembly includes a housing having an aperture and a magnet at least partially disposed within the housing. A first surface of the magnet is exposed. The barrier assembly also includes a light-emitting component disposed within the aperture. Another embodiment of a barrier assembly includes a housing having a plurality of apertures formed about a perimeter of the housing. The barrier assembly also includes a magnet at least partially embedded within the housing and the magnet includes an opening formed through a center of the magnet and a plurality of light-emitting components, each light-emitting component at least partially disposed within a corresponding aperture of the plurality of apertures.

A magnetic alignment assembly can be incorporated into an electronic device to facilitate alignment with another device. The magnetic alignment assembly can include a main magnet (e.g., a square or rectangular magnet) having a magnetic dipole in an axial direction and a ring magnet coaxial with the main magnet. The ring magnet can be smaller than the main magnet. The ring magnet can be positioned between the main magnet and an interface surface.

A substrate transfer device is provided with: a movement tile provided in a substrate transfer region and including first magnets for changing a state of a magnetic field and a movement surface; a substrate transfer module including a second magnet that receives a magnetic force and configured to move along the movement surface while being floated from the movement surface by the magnetic force; a transfer controller for controlling the magnetic field formed by the first magnets to move the substrate transfer module along a preset route; a detector for detecting an index value corresponding to a magnitude of a deviation, from the preset route, of an actual movement path of the substrate transfer module moving along the movement surface; and a correction parameter calculation part for calculating a correction parameter for correcting the magnetic force acting on the second magnet based on the index value.

Described are systems and methods for magnetically assisted boom refueling. In certain examples, a magnetic refueling receiver is disclosed that includes a refueling receptacle configured to receive a portion of a refueling boom and a receptacle magnet disposed around at least a portion of a perimeter of the refueling receptacle. In another example, a magnetic refueling boom is disclosed that includes a refueling boom structure that includes a first end configured to be inserted into a refueling receiver and a pipe magnet disposed around at least a portion of a perimeter of the refueling boom structure.

A power reception device includes: a housing including a first surface facing in a first direction, a second surface facing in a second direction opposite to the first direction, and a side surface surrounding a space between the first surface and the second surface; a coil antenna wound in a circle; a shielding sheet disposed over the coil antenna; and a first magnet and a second magnet adjacent to an outermost coil of the coil antenna and disposed to be spaced apart from the outermost coil. The first magnet is disposed so that a portion of magnetism induced by the first magnet is formed in the first direction. The second magnet is disposed so that a portion of the magnetism induced by the second magnet is formed in a third direction that is an outside direction from a center of the coil antenna.

A power transmitter is configured for transmission of wireless power, to a wireless receiver, at extended ranges, including a separation gap greater than 8 millimeters (mm). The power transmitter further includes a coil configured to transmit the power signal to a power receiver, the coil formed of wound Litz wire and including at least one layer, the coil defining, at least, a top face. The power transmitter further includes a shielding comprising a ferrite core and defining a cavity, the cavity configured such that the ferrite core substantially surrounds all but the top face of the coil. The power transmitter includes at least one magnet, the at least one magnet configured to attract at least one receiver magnet when a power receiver is proximate to a surface associated with the power transmitter.
