Assignee: PENUMBRA, INC.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 4:
5. A method, comprising:
(a) causing, using processing circuitry, a transmitter to generate a magnetic field associated with a first frequency;
(b) causing, using the processing circuitry, a receiver to sense the magnetic field based on the first frequency;
(c) determining, using the processing circuitry, an expected amount of jitter from the magnetic field at the first frequency;
(d) measuring, using the processing circuitry, an actual jitter from the magnetic field at the first frequency;
determining, using the processing circuitry, that there is excessive actual jitter based on a comparison of the expected jitter and the actual jitter;
in response to determining that there is excessive actual jitter, repeating (a) through (d) for a frequency different from the first frequency until it is determined that there is no excessive actual jitter;
providing, using the processing circuitry, an indication of the position and the orientation of the receiver relative to the transmitter based on the magnetic sensor data and based on the frequency at which there is no excessive actual jitter.
