Abstract: This disclosure provides systems, methods and apparatus for wireless power transfer. In one aspect the disclosure provides an apparatus for wirelessly communicating power. The apparatus includes a first conductive structure, with a length greater than a width, configured to wirelessly receive power via a magnetic field. The first conductive structure includes two substantially co-planar loops. The first conductive structure has a first edge and a second edge each intersecting a geometric line along the length of the first conductive structure. The apparatus further includes a second conductive structure, with a length greater than width, positioned between the first conductive structure and a magnetic material and configured to wirelessly receive power via the magnetic field. The length of the second conductive structure is substantially equal to at least a distance along the geometric line between the first edge and the second edge of the first conductive structure.

Abstract: An apparatus for detecting a presence of an object can include a plurality of electrically conductive loops arranged in an array. The apparatus includes a sensor circuit configured to determine a characteristic associated with each of the plurality of loops. The apparatus includes a hardware processor configured to, for each loop of the plurality of loops, determine a parameter based on the characteristic associated with the loop and the characteristic associated with at least one adjacent loop. The hardware processor may be further configured to determine the presence of the object based on the parameter. The parameter may comprise a sum of a difference between the characteristic associated with the loop and a reference value for the characteristic, and a difference between the characteristic associated with each of the at least one adjacent loop and the reference value.
