Patent Number Title Of Patent Date Issued
8121812 AC magnetic tracking with phase disambiguation February 21, 2012
A method and system for magnetic locating resolves phase ambiguity. The system uses time-division multiplexed magnetic fields emitted from plural transmit coils. The magnetic fields are alternating fields at a carrier frequency, and the fields emitted from different coils in different
8013595 AC magnetic tracking system with phase locking September 6, 2011
Plural transmitter coils of a magnetic locating system are driven with widely-separated main frequencies. One of the transmitter coils is also driven with a marker frequency close to the main frequency applied to that coil. The receiver determines a phase relationship with the transm
