Separable toroidal segments reduce the size of a sensing transformer that can be installed on an electrical conductor while connected to a device.

A power supply system is capable of feeding electric power from a power adapter to a plurality of load devices. The power adapter includes a primary core; and a primary coil wound around the primary core for serving as a output port of the power adapter to output an alternating current. The load devices include secondary cores for simultaneously forming magnetic circuits between the primary core and the load devices; and secondary coils wound around the secondary cores for feeding output power to the load devices. The primary core has two pairs of protrusions, and the secondary cores are arranged on opposite sides of the primary core in such a manner that the primary core lies between the secondary cores to feed electric power simultaneously to the load devices.

A particle (10) of ferromagnetic powder for use in preparation of soft magnetic core components has a core-shell structure. The particle includes a central core (12) and a shell (14) coated on the central core. The central core is made of magnetic material and is used for providing the necessary magnetic property for the magnetic core components made from the ferromagnetic powder. The shell has a higher electrical resistance than the central core so as to reduce an eddy current loss of the magnetic core component. The shell also functions to provide an excellent bonding strength between particles of the powder.

Described herein are improved configurations for a wireless power transfer. Described are methods and designs for implantable electronics and devices. Wireless energy transfer is utilized to eliminate cords and power cables puncturing the skin to power an implantable device. Repeater resonators are employed to improve the power transfer characteristics between the source and the device resonators.

A matrix integrated magnetics (MIM) “Extended E” core in which a plurality of outer legs are disposed on a base and separated along a first outer edge to define windows there between. A center leg is disposed on the top region of the base and separated from the outer legs to define a center window. The center leg is suitably positioned along a second outer edge opposite the first or between outer legs positioned along opposing outer edges. A plate is disposed on the outer legs opposite the base.

An auto-aligning and connecting structure used to connect and align an electronic device and an accessory, wherein a plurality of first magnetic bodies are disposed on a first surface of the electrical device and a plurality of second magnetic bodies are disposed on a second surface of the accessory. The magnetic pole of the first magnetic bodies and the second magnetic bodies are appropriately arranged so the first magnetic bodies and the second magnetic bodies can attract each other when the first surface and the second surface approach each other. Then, the electronic device and the accessories are connected to each other when the first surface and the second surface connect.

A magnetic attachment mechanism and method is described. The magnetic attachment mechanism can be used to releasably attach at least two objects together in a preferred configuration without fasteners and without external intervention. The magnetic attachment mechanism can be used to releasably attach an accessory device to an electronic device. The accessory device can be used to augment the functionality of usefulness of the electronic device.

The lightweight bulletproof metal matrix macrocomposites (MMMC) contain (a) 10-99 vol. % of permeable skeleton structure of titanium, titanium aluminide, Ti-based alloys, and / or mixtures thereof infiltrated with low-melting metal selected from Al, Mg, or their alloys, and (b) 1-90 vol. % of ceramic and / or metal inserts positioned within said skeleton, whereby a normal projection area of each of said inserts is equal to or larger than the cross-section area of a bullet or a projectile body. The MMMC are manufactured as flat or solid-shaped, double-layer, or multi-layer articles containing the same inserts or different inserts in each layer, whereby insert projections of each layer cover spaces between inserts of the underlying layer. The infiltrated metal contains 1-70 wt. % of Al and Mg in the balance, optionally, alloyed with Ti, Si, Zr, Nb, V, as well as with 0-3 wt. % of TiB2, SiC, or Si3N4 sub-micron powders, to promote infiltrating and wetting by Al-containing alloys. The manufacture includes (a) forming the permeable metal powder and inserts into the skeleton-structured preform by positioning inserts in the powder followed by loose sintering in vacuum to provide the average porosity of 20-70%, (b) heating and infiltrating the porous preform with molten infiltrating metal for 10-40 min at 450-750° C., (c) hot isostatic pressing of the infiltrated composite, and (d) re-sintering or diffusion annealing.
