Wireless medical location tracking

Abstract

To provide a dongle apparatus.SOLUTION: In one embodiment, a dongle apparatus is configured to augment a patient interface unit (PIU) retrofitted with the dongle apparatus, and comprises: a connector configured to be physically connected to an interface of the PIU; at least three load circuits configured to receive at least three corresponding alternating current (AC) signals from the PIU via the connector and mimic a load of at least three corresponding magnetic field generator coils of a location pad; sampling circuitry configured to sample a current amplitude and a phase of the at least three AC signals in the at least three load circuits; and wireless communication circuitry configured to wirelessly send data about the current amplitude and the phase of the at least three AC signals to a driver of the location pad. Additional embodiments are described herein.SELECTED DRAWING: Figure 1
