A system and method for integrating a magnetic component within a power converter includes a coil integrated on a PCB. The PCB includes multiple layers and traces on each layer to form a single coil or to form multiple coils on the magnetic component. The PCB further includes at least one opening in the PCB through which a core component may pass, such that the magnetic component is defined by the coils and the core material. To reduce eddy currents built up within the traces, the dimensions of traces on a layer are varied and the position of traces between layers of the PCB are varied. The widths and locations of individual traces are selected to reduce coupling of the trace to leakage fluxes within the magnetic component. A floating conductive layer may also be provided to still further reduce the magnitude of eddy currents induced within the coil.

A connection structure according to an embodiment disclosed in the present disclosure includes: a first connection part provided on a surface of a first member, the first member including at least one conductor pattern; and a second connection part provided on a surface of a second member, the second member having at least one conductive pad formed on a surface thereof and configured to be coupled to a surface of the first connection part by a magnetic force so that at least one conductor pattern and at least one conductive pad are electrically connected to each other.

A soft neural interface connector apparatus includes a PCB having a two-dimensional array of solder balls, a transparent top board, a cushioning layer on one side of the transparent top board, and a soft neural interface including a flexible and/or stretchable microelectrode array (MEA) through which neural signals are obtained or delivered. The MEA includes a two-dimensional array of contact pads corresponding to the array of solder balls. The PCB, the transparent top board, the cushioning layer, and the MEA are stacked together such that the MEA is between the cushioning layer and the PCB, and the contact pads are aligned with and in electrical contact with associated solder balls. A magnetic connector system having at least one magnetic connector component on the transparent top board is magnetically connected with at least one magnetic connector component on the PCB to press the contact pads and associated solder balls together.

A contactless connector includes: a circuit board; a light emitter arranged on the circuit board and capable of converting electrical signals into optical signals; a light emitter control chip arranged on the circuit board for controlling the operation of the light emitter; and a light-transmitting member at least partially covering the circuit board, the light emitter, and the light emitter control chip.

A polyhedral LED display screen is provided and includes multiple cabinet main frames. Each the cabinet main frame is formed with an accommodating cavity. A side of each cabinet main frame is provided with a flexible PCB, an outer side of the flexible PCB facing away from the cabinet main frame is disposed with LED lamp beads, an inner side of the flexible PCB facing towards the cabinet main frame is magnetically connected to the cabinet main frame, and the cabinet main frames are connected to each other to form a regular dodecahedron sphere. The multiple cabinet main frames can be completely covered by the flexible PCBs, a missing display at an end point in the prior art is eliminated, design numbers and complexities of the cabinet main frames and the flexible PCBs are reduced, and an installation of the cabinet main frames becomes more convenient.

An icosahedral LED display screen belongs to the field of display screens and includes multiple cabinet main frames. Each cabinet main frame is formed with an accommodating cavity. A side of each cabinet main frame is provided with a flexible PCB, an outer side of the flexible PCB is disposed with LEDs, and an inner side of the flexible PCB is provided with a magnet fixedly therewith. The multiple e.g., twenty cabinet main frames are mutually connected to form an icosahedral sphere which has no end point similar to a football, and polygons that make up the sphere are the same, and therefore the cabinet main frames can be completely covered by the flexible PCBs to eliminate a missing of display at an endpoint and reduce design numbers and complexities of the cabinet main frames and the flexible PCBs. An installation of the LED display screen becomes more convenient.

An improved distributed-output multi-cell-element power converter utilizes a multiplicity of magnetic core elements, switching elements, capacitor elements and terminal connections in a step and repeat pattern. Stepped secondary-winding elements reduce converter output resistance and improve converter efficiency and scalability to support the high current requirements of very large scale integrated (“VLSI”) circuits.

An electronic component module includes a board, an electronic component, a sealing portion, a metal layer, and a magnetic layer. The board has a first main surface. The electronic component is provided on a first main surface of the board. The sealing portion seals the electronic component. The metal layer covers the sealing portion. The magnetic layer is provided between the sealing portion and the metal layer. The magnetic layer has a magnetic main body and a first cover sheet. The first cover sheet is provided between the magnetic main body and the metal layer. The first cover sheet has a first main surface and a second main surface. The first main surface faces the magnetic main body. The second main surface faces the metal layer. The second outer peripheral end of the second main surface is located inside the first outer peripheral end of the first main surface.
