Multipole elastomeric magnet with magnetic-field shunt
A multipole permanent magnet may be provided with a magnetic-field shunt. The multipole permanent magnet may be formed from compression-molded magnetic particles such as magnetically anisotropic rare-earth particles in an elastomeric polymer. The magnetic-field shunt may be formed from magnetic members in a polymer binder that are separated by gaps to allow the shunt to flex or from magnetic particles in a polymer binder. The magnetic particles in the polymer binder may be ferrite particles or other magnetic particles. The polymer binder may be formed from an elastomeric material and may be integral with the elastomeric polymer of the multipole permanent magnet or separated from the elastomeric polymer of the multipole permanent magnet by a polymer separator layer. Conductive particles may be formed in polymer such as the elastomeric polymer with the magnetic particles. The conductive particles may be configured to form electrical connector contacts and other signal paths.
Nonreciprocal Circuit Element and Method of Manufacturing the Same
A cavity is formed in a surface of a dielectric component on the permanent magnet side. The cavity has a bottom surface extending in a direction along one main surface and a side surface extending in a thickness direction crossing the bottom surface. At least a part of the permanent magnet is disposed in the cavity. A surface of at least a part of the permanent magnet disposed in the cavity is fixed to both of the bottom surface and the side surface through an adhesive.
Flexible magnetic fastening apparatus
A flexible magnetic fastening apparatus with enhanced strength and reduced noise during use is provided. The magnetic fastening apparatus includes an upper fastener detachably coupled to a lower fastener. Each fastener in the upper and lower fasteners has a fabric layer that encapsulates a magnetic member. The magnetic member in each fastener has a positive magnetic pole at the bottom surface of the fabric layer and a negative magnetic pole at the top surface of the fabric layer. The negative magnetic pole of the magnetic member in the lower fastener attracts the positive magnetic pole of the magnetic member in the upper fastener, thereby coupling the bottom surface of the upper fastener to the top surface of the lower fastener.
Data line convenient for storage
A data line convenient for storage includes a data line body (1); a plurality of magnetic rings (2) sleeve on the data line body (1); and a plurality of limit tube (3). Each limit tube (3) is arranged between each two adjacent magnetic rings (2). Two opposite ends of each limit tube (3) respectively abuts against the two adjacent magnetic rings (2). When the data line is coiled and stacked into a multiple-layer structure, the magnetic rings (2) located at two adjacent layers attract each other. The magnetic rings (2) at two adjacent layers can attract each other to fix the adjacent layers tightly for storage. The data line is simple in structure, each to use and properly designed to improve user experience.
Magnetic holding system with enhanced magnetic strength
A magnetic holding system for securely affixing an object to a wall surface including a first magnetic sheet layer having specific polarity line spacing, a second layer having magnetic receptive properties, and finally an object with a mounting surface designed to abut the second layer, the mounting surface including a magnetic material having specific polarity line spacing that is substantially the same as the specific polarity line spacing of the first layer and a sheet of steel, such that, when the object polarity line spacing is aligned with the first layer polarity line spacing, the object is securely held to the wall.
Wearable device
A wrist-worn device having the form of a continuous loop. The device comprises a plurality of elongate links, each link comprising at least one magnet, the links being connected to form a chain with neighbouring links being pivotable with respect to one another about a pivot axis that is substantially radial with respect to said loop. The magnets of neighbouring links have a respective positioning and polarity to provide an attractive force between the pair of neighbouring links when the pair of neighbouring links are in a side-by-side arrangement, whereby the chain of links has a first configuration in which the links are retained by the attractive force in the side-by-side arrangement, and a second configuration of greater length than the first configuration.
MAGNET ALTERNATING POLE ARRAY MAGNETIZED BY ONE SIDE MAGNETIZATION TO BOOST MAGNETIC ATTRACTION FORCE
A flexible magnetic component can include a magnetizable powder including a rare earth element. The flexible magnetic component can also include a polymer binder. The flexible magnetic component can define a first surface and a second surface opposite the first surface. A first magnetic field adjacent to the first surface can have a field strength at least 3 times greater than a field strength of a second magnetic field adjacent to the second surface, and the flexible magnetic component can elongate greater than 20% before a permanent deformation occurs.

Immunity from magnetic disturbance for a magnetic location tracker
Apparatus, including a ferromagnetic sheet and at least one radiator, mounted in proximity to the ferromagnetic sheet and configured to radiate a magnetic field into a region in proximity thereto. The apparatus further includes a solid sheet of thermal insulation, mounted between the ferromagnetic sheet and the at least one radiator so as to prevent transfer of thermal energy from the at least one radiator to the ferromagnetic sheet.
MAGNETIC MOUNT FOR ELECTRONIC DEVICES
An electronic device mount includes a rigid cover, a flexible cover, and a frame positioned between the rigid cover and the flexible cover. The frame has a plurality of openings. The electronic device mount further includes a plurality of rocker arms coupled within correspond openings of the frame, and to the flexible cover. The plurality of rocker arms are configured to pivot within the plurality of openings to deflect the flexible cover relative to the frame to define a curved outer surface of the flexible cover. The electronic device mount also includes a plurality of magnets coupled to one of the frame or the flexible cover. The deflection of the flexible cover is self-adjusting to allow for easy mounting of an electronic device to a curved metal surface.
