A method and apparatus for monitoring grounding of personnel and equipment in electrostatic discharge sensitive areas. The engine duct and the generator duct can be formed in one body as an exhaust duct. A processor receives measured non-gravity forces from the accelerometer, estimates the contributions of the measured non-gravity forces to the movement of the satellite, and predicts the orbit of the satellite based on the estimated contributions of the non-gravity forces to the movement of the satellite. Additionally, the recess is configured and arranged to permit removal of the Type III PC card from the Type III PC card slot, without also necessitating removal of the wireless PC card. The target input mechanism is configured to receive a user indication of the presence of an object of interest to generate location data from the GPS receiver for the object of interest. The vacuum deposited dielectric thin film is patterned using sacrificial structures formed by shadow mask techniques.
