Claim Text:
1. A proximity sensing system, the system comprising: a plurality of antenna arrangements, each comprising an electrode and a shield electrode; a plurality of spaced apart integrated circuit devices comprising proximity sensing circuits associated with the plurality of antenna arrangements, wherein each integrated circuit device comprises: a coordinating circuit, wherein the coordinating circuit is coupled to each of the plurality of proximity sensing circuits, wherein the coordinating circuit comprises logic configured to: set one of the plurality of proximity sensing circuits into the first mode and remaining ones of the plurality of proximity sensing circuits into the second mode; wherein the one of the plurality of proximity sensing circuits which is set into the first mode operates only as a transmitter while in the first mode, and the remaining ones of the plurality of proximity sensing circuits operate only as receivers while in the second mode and receive through capacitive coupling an electric field emitted by the one of the plurality of proximity sensing circuits which is set into the first mode.
