ABSTRACT:
An apparatus for facilitating calibration of sensors embedded within an object includes: a foundation; a force generator mounted on the foundation configured to generate a force in a first direction; a load cell connected with the force generator that detects the magnitude of force applied by the force generator; a roller mounting assembly pivotally interconnected with the foundation and pivotable about a first axis of rotation, the first axis of rotation being generally perpendicular to the first direction; and a roller rotatably mounted on the roller mounting assembly for rotation about a second axis of rotation, the second axis of rotation being generally perpendicular to the first direction, the roller protruding in the first direction sufficiently to apply a force to the object. This apparatus can enable force applied to the sensor to be calibrated with sensor output.
