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

Claim 8:
9. A non-transitory computer readable storage medium having embodied thereon instructions for causing a computing device to execute a method, the method comprising:
(a) causing a transmitter to generate a magnetic field associated with a first frequency;
(b) causing a receiver to sense the magnetic field based on the first frequency;
(c) determining an expected amount of jitter from the magnetic field at the first frequency;
(d) measuring an actual jitter from the magnetic field at the first frequency;
determining 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 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.
