Abstract: A system for inductive power transmission includes at least one interface surface and a plurality of triangular coil elements positioned underneath the interface surface such that at least one edge of the respective triangular coil element is adjacent to an edge of at least one other of the triangular coil elements. Each of the triangular coil elements may be operable to inductively transmit power to at least one coil of at least one electronic device and/or inductively receive power from the coil of the electronic device. Each triangular coil element may be operable to detect the proximity of one or more inductive coils of one or more electronic devices and inductively transmit power upon such detection at different frequencies, power levels, and/or other inductive power transmission characteristics.

Abstract: Methods and systems for improved efficiency when an inductive power transmitter associated with an inductive power transfer system experiences a low-load or no-load condition. More particularly, methods and systems for detecting when an inductive power receiver is absent or poorly connected to an inductive power transmitter. The inductive power transmitter includes, in one example, a current peak monitor coupled to an inductive power transmit coil. The current peak monitor waits for a current peak resulting from spatial displacement of a magnetic field source within the inductive power receiver, indicating to the inductive power transmitter that the inductive power receiver is moving, or has moved, toward the inductive power transmitter. Other examples include one or more Hall effect sensors within the inductive power transmitter to monitor for the magnetic field source of the inductive power receiver.

Abstract: An inductor coil for an inductive energy transfer system includes multiple layers of a single wire having windings that are interlaced within at least two of the multiple layers such that both an input end and an output end of the wire enter and exit the coil on a same side of the coil. The input end and the output end of the wire may abut one another at the location where the input and output wires enter and exit the inductor coil. The wire can include one or more bundles of strands and the strands in each bundle are twisted around an axis extending along a length of the wire, and when there are at least two bundles, the bundles may be twisted around the axis. At least one edge of the inductor coil can be formed into a variety of shapes, such as in a curved shape.

Abstract: A first component is coupled to a second component by one or more joints. Magnetic force between at least a first magnetic and second magnetic unit preloads the joint by placing the joint in compression. The first and second magnetic units may be respectively coupled to the first and second components. The magnetic force acts as a retentive force between coupled components and/or the joint and operates to resist one or more tensile and/or other opposing forces. In some cases, the first magnetic unit may be a shield, such as a direct current shield, that protects one or more components from a magnetic field of the second magnetic unit.

Abstract: An inductor coil includes a wire which is wound in alternating layers such that the surface area of the wire in each winding viewed from above or below the coil is substantially equal in each half of the coil defined by a line bisecting the center point in each layer. The layers are also wound in a serpentine fashion to balance the capacitance between layers. The substantially equal surface area of wire in each half of a coil layer and in adjacent coil layers results in a balanced capacitance of the coil which, in turn, results in reduced common mode noise.
