Dynamic transmitter power control for magnetic tracker
First Claim
1. A computer system for dynamically modifying a transmission strength of a magnetic field signal, the system comprising:
- one or more processors; and
one or more computer-readable media having stored thereon executable instructions that when executed by the one or more processors configure the computer system to perform at least the following;
determine the transmission strength of the magnetic field signal, the magnetic field signal being transmitted from a first magnetic-sensor device to a second magnetic-sensor device;
determine a first projected distance between the first magnetic-sensor device and the second magnetic-sensor device;
based at least in part on the first projected distance, calculate an adjusted transmission strength for the magnetic field signal;
cause the first magnetic-sensor device to transmit an adjusted magnetic field signal, wherein the adjusted magnetic field signal comprises the adjusted transmission strength;
receive, from the second magnetic-field device, the adjusted magnetic field signal; and
based at least in part upon the received adjusted magnetic field signal, compute a first pose of the first magnetic-sensor device in relation to the second magnetic-sensor device.

Abstract
A system determines the transmission strength of the magnetic field signal. The magnetic field signal is transmitted from a first magnetic-sensor device to a second magnetic-sensor device. The system then determines a first projected distance between the first magnetic-sensor device and the second magnetic-sensor device. Based at least in part on the first projected distance, the system calculates an adjusted transmission strength for the magnetic field signal. The system then causes the first magnetic-sensor device to transmit an adjusted magnetic field signal. The adjusted magnetic field signal comprises the adjusted transmission strength. The system receives, from the second magnetic-field device, the adjusted magnetic field signal. Based at least in part upon the received adjusted magnetic field signal, the system, computes a first pose of the first magnetic-sensor device in relation to the second magnetic-sensor device.
