Method and machine for navigation system calibration
First Claim
1. A calibration machine for calibrating sensory controls of an ultrasonic navigation system comprising a wand and a receiver for measuring one of alignment, position, and distance, the calibration machine comprisingan enclosure for containing a paired device group that monitors air temperature and air flow therein;
- one or more holder mechanisms for rigidly mounting each the wand and receiver of the paired device group at a specific orientation;
a rail system for holding the one or more holder mechanisms at a specific location and orientation within the enclosure; and
a computer communicatively coupled to the one or more holder mechanisms forprecisely orienting the paired device group in a predetermined configuration along the rail system;
calibrating sensor characteristics of the wand and receiver as a function of distance and rotation between the wand and the receiver for the predetermined configuration; and
storing tuning parameters associated with the calibrating of sensor characteristics to files recording precise calibration of transducer characteristics of the wand and receiver paired device group with respect to the air temperature and air flow.

Abstract
A method of calibration and a calibration machine is provided for calibrating sensory controls of an ultrasonic navigation system. It can include an enclosure for containing a paired device group to minimize air flow therein, one or more holder mechanisms for rigidly mounting the paired devices at specific and adjustable orientations, and a rail system for holding the one or more holder mechanisms at specific locations within the enclosure. A computer communicatively coupled to the calibration machine can precisely adjust actuators for configuring the distances and orientations of the holding mechanisms and control a transmission and reception of the paired devices for calibrating the paired devices.
