Abstract:
1. Electromechanical apparatus, comprising: an electromechanical device, which is powered by electricity and is turnable and moveable in any direction on a support surface, said electromechanical device having a plurality of electric contacts that are spaced apart in relation to each other in positions to make electric contact with the support surface, said electric contacts being electrically connected to a rectifier circuit that is capable of rectifying electric power from said electric contacts whenever at least one of said electric contacts is at a first voltage level and at least another one of said electric contacts is at a second voltage level; a contact system having a plurality of pads that comprise at least part of said support surface, wherein some of said pads are at the first voltage level and others of said pads are at the second voltage level, and further wherein the pads at the first voltage level are interspersed with the pads at the second voltage level in such a manner that movement of the electromechanical device in any direction on the support surface can result in a condition in which at least one of the contacts touches at least one pad at the first voltage level while at least one other of the contacts touches at least one pad at the second voltage level.
