A high current and RPM-capable slip ring assembly for use in a selected application for transferring electricity between an exterior environment and an interior environment that includes a non-rotating electrical power member with concentric electrically conducting power transmission bands with wiring and a rotating electrical power member with concentric electrically conducting power transmission bands with wiring and a housing that surrounds both the non-rotating electrical power member and rotating electrical power member to align the first set of concentric electrically conducting power transmission bands and the second set of concentric electrically conducting power transmission bands to slide on one another during rotationally operation of the slip ring assembly.

There is provided a current transferring device for an electric machine comprising a rotary bearing member fixed in a rotor shaft and rotating with it and a non-rotary component. The rotary bearing member includes a first compartment filled with a conducting fluid and having a first opening and a rotor positive connector that is in electrical contact with the conducting fluid therein and electrically connected to a rotor positive pole, and a second compartment filled with a conducting fluid and electrically insulated from the first compartment and having a second opening and a rotor negative connector that is in electrical contact with the conducting fluid therein and electrically connected to a rotor negative pole. The non-rotary component closes the first and second openings.

A slip ring for transferring electrical signals between rotating and static elements of a device includes a rotating element, a static element, an electrical contact assembly, including a plurality of subassemblies, contacting the rotating element and static element, one subassembly including a deformable PCB, and a spring element positioned to supply an axially aligned force to a face of the PCB to facilitate electrical contact between the PCB and other electrical contacts elements on another subassembly.

A method for making contact wires for sliprings comprising the steps of: coating and/or plating a wire with a first metal of the group of nickel, chrome or a combination thereof; coating and/or plating the wire with a second metal of the group of gold, silver, or a combination thereof; delivering laser radiation and generating an interference pattern of the laser radiation to the surface of the wire; heating the surface selectively as defined by the interference pattern, modifying of the crystal structure and/or providing protrusions and/or recesses due to melting and/or evaporation of the surface material.

A flexible electronic apparatus is provided. The flexible electronic apparatus includes a housing, a roller received in the housing, a main body wound around the roller, a control module, an end cover, and a rotating shaft. The roller rotates relative to the end cover by the rotating shaft. The end cover is provided with a functional module. The control module is disposed in the roller. A wire is electrically coupled to the control module and the functional module. When the main body is retracted, the wire is wound around the rotating shaft in a first direction. When the main body is extended, the wire is wound around the shaft in a second direction opposite to the first direction.
