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.

18. A method of detecting a topology of an assembly of building blocks comprising, at a building block in the assembly:
-
detecting an orientation of the block and based on the detected orientation, connecting a processor in the block to one of a plurality of coupling elements in the block, each coupling element being positioned adjacent to a different face of the block and the plurality of coupling elements comprising a plurality of antennas or a plurality of electrodes; transmitting, in response to a request received from a transceiver module, an identifier for the block from the processor to the transceiver module via the coupling element connected to the processor; in response to receiving a close signal from the transceiver module, sending a control signal from the processor to an RF switch in the block, the control signal indicating an additional coupling element of the plurality of coupling elements in the block; and causing, by the processor, the RF switch to selectively connect the processor to the additional coupling element of the plurality of coupling elements by closing the RF switch in the block. - View Dependent Claims (19, 20)
