1. A method of extracting power from a power delivery surface comprised of a plurality of rectangular, parallel contact strips, wherein adjacent contact strips are separated from each other by a non-conductive gap and energized with opposite polarities, comprising the acts of:
- arranging at least three electrically conductive contacts, which have contact surfaces smaller than the non-conductive gap, into a linear contact array;
placing the linear contact array on the power delivery surface in a manner that at least one of the contacts touches a contact strip of one polarity and at least one other of the contacts touches a contact strip of opposite polarity; and
conducting electricity from the contact strips, through the contacts that touch the contact strips, to an electronic circuit that provides a load.

Abstract
A linear contact array comprising three contacts is provided for wire-free electric power extraction from a power delivery pad for mobile electronic devices. The linear contact array is configured to assure effective contact for power transfer from the power delivery pad and the mobile electronic device anywhere on the power delivery surface for a range of angular orientations of the linear array in relation to the power delivery surface.

11. Power receiver apparatus for extracting electric power from a power delivery surface that has a plurality of rectangular, parallel, contact strips, wherein adjacent contact strips are separated from each other by a non-conductive gap and energized with opposite polarities, comprising:
at least three electrically conductive contacts arranged in a linear contact array, wherein each of the three contacts has a contact surface that is smaller than the gap and is spaced a distance from the adjacent contact that provides 100 percent probability of at least one of the three contacts touching a contact strip of the opposite polarity with the linear array of the three contacts positioned at any lateral position on the power delivery surface and oriented within an angular tolerance range of zero to 41 degrees either direction from a line that is perpendicular to the direction of a major axis of the rectangular contact strips. - View Dependent Claims (12, 13, 14, 15, 16)

17. Power receiver apparatus for extracting electric power from a power delivery surface having a plurality of oppositely charged, electrically conductive contact surfaces separated by non-conductive gaps, comprising:
at least three electrically conductive contacts aligned in a linear array, each of which contacts has a contact surface that is smaller than the gap, and wherein each of the contacts is spaced a distance from adjacent contacts that provides 100 percent probability of at least one of the contacts touching a conductive contact surface on the power delivery surface of one polarity and at least another of the contacts touching a conductive contact surface of opposite polarity with the linear array of contacts positioned at any lateral position on the power delivery surface and oriented within an angular tolerance range of zero to 82 degrees.
