A method for characterizing distortions in the earth’s magnetic field caused by a vehicle having a magnetometer affixed therein is described. The first group of LEDs operates in a non-operating condition, a running condition where each LED of the first array is illuminated at first intensity, and a braking condition where each LED is illuminated at a second, brighter intensity. The shaft includes a viewable region along a length of the shaft and a lumen to slidably receive the endoscope. The customer registers its own authentication and authorization security module with the cloud security service, and that security module is then used to control what persons or entities can access information associated with the deployed application. Each bi-axial linkage includes a first flexure beam configured to flex about a first axis and a second flexure beam attached to the first flexure beam.
