Power transfer surface for game pieces, toys, and other devices
First Claim
1. A power transfer system for providing power to electrically powered game pieces, toys, or other devices, comprising:
- a power transfer surface comprising two separate conductive surface sections that are not in electrical contact with each other on a substantially non-conductive substrate so that the two separate conductive surface sections of the power transfer surface can be charged at different voltage levels from each other, wherein one of the two separate conductive surface sections has a header trace portion that forms one marginal edge portion of the power transfer surface and the other separate conductive surface section has a header trace portion that forms an opposite marginal edge portion of the power transfer surface, and wherein each of the two separate conductive surface sections is shaped with a plurality of conductive columns extending in spaced-apart in relation to each other from the respective header trace portion of that respective conductive surface section toward, but not all the way to, the opposite header trace portion of the other conductive surface section such that the columns of one of the conductive surface sections are interdigitated with the columns of the other conductive surface section and with edges of the columns of one of the conductive surface sections are in fitting, but not electrical contacting, relation with edges of the columns of the other conductive surface section to form a continuous surface, and wherein the columns have non-linear edges that alternatively widen and narrow such that individual columns are shaped with a plurality of widened pads connected electrically to adjacent widened pads by narrow connecting portions of the column that extend between adjacent pads; and
a power source, electrically coupled to the two separate conductive surface sections in a manner that applies charges to the respective separate conductive surface sections at different voltage levels or polarities.

Abstract
Various contact systems and methods for manufacturing and using such are disclosed herein. Examples of the contact systems include a surface with one set of pads biased at a first voltage level, and another set of pads biased at a second voltage level. Such a contact system can be used, for example, to transfer power to an electromechanical device disposed thereon. In one particular example, the electromechanical device can include a power storage element and two or more couplings. When one of the couplings contacts a pad biased at the first voltage level, and another of the couplings contacts a pad biased at the second voltage level, a circuit is completed where some derivative of the differential between the first voltage level and the second voltage level is placed across the power storage element. Completion of the circuit causes the power storage element to charge. Power can be drawn from the power storage element to operate the electromechanical device.
