A magnetic force sensor assembly for a workholding fixture includes a magnetic force switch operatively supported by a base of a component disposed on the workholding fixture. This aircraft data can be used to perform additional monitoring of aircraft sub-systems to detect an abnormal condition, andor to identify one or more sources that are causing the abnormal condition. The light is introduced into the cavity in an off-axis alignment to systematically eliminate cavity resonances, while preserving the absorption signal amplifying properties of such cavities. A first LUT output terminal is non-programmably coupled to the interconnect structure via a first output terminal of the logic block.
