Abstract

Apparatus for remote interaction with an object of interest includes a remote station for obtaining information from the object of interest, a base station for transmitting energy in space to and communicating with the remote station and the remote station having conversion means for energizing the remote station responsive to receipt of the transmitted energy. The energy may be of any suitable type including RF power, light, acoustic, magnetic energy or other form of space transmitted or “radiant” energy. The remote station does not have to contain a source of stored energy or a wired connection to a source of energy. The remote station receives the energy transmission and data transmission from the base station and transmits data to the base station. Microprocessor controllers may be provided for the base station and the remote station The remote station may receive information from sensors and through one or more transponders sequentially communicate information to the base station An associated method is provided. In other embodiments which are suited for use in miniaturized electronic chip systems, power enhancement and increased effective antenna size are provided.
