Abstract:
1. An apparatus, comprising: at least one device from a set of devices consisting of: (a) a portable electrical device capable of storing electrical energy and requiring periodic recharging, and (b) a charging device for supplying electrical energy to said portable electrical device during recharging thereof; wherein said portable electrical device and said charging device comprise respective complementary mating surfaces which transmit electrical energy from said charging device to said portable electrical device during recharging of said portable electrical device, each said mating surface having a respective first plane of symmetry bisecting the mating surface, the mating surface being symmetrical about the respective first plane of symmetry, and a respective second plane of symmetry bisecting the mating surface and perpendicular to the respective first plane of symmetry, the mating surface being symmetrical about the respective second plane of symmetry, each said mating surface defining a convex polygon in a plane perpendicular to both its respective first plane of symmetry and its respective second plane of symmetry, said respective complementary mating surfaces being in an aligned configuration opposing each other in which said first planes of symmetry and said second planes of symmetry are substantially coincident during recharging; and wherein said portable electrical device is placed upon said charging device by a user, said portable electrical device aligning its mating surface with respect to the mating surface of the charging device automatically using a gravitational force.
