Title: ELECTROMAGNETICALLY COUPLED BUILDING BLOCKS
Abstract:
A building block is described which has a plurality of faces each with an associated coupling element, such that a first coupling element is adjacent to a first face and a second coupling element is adjacent to a second face, etc. An RF switch in the block is arranged to selectively couple two of the coupling elements together under the control of a processor. The processor controls the RF switch in response to signals received from a transceiver module. A sensing and switching arrangement within the building block selectively connects the processor to one of the coupling elements based on a detected orientation of the block (e.g. so that power harvested from the transceiver module can be used to power the processor). The coupling elements are either all antennas or all electrodes.
