Abstract

An electronic device that includes a field-emitting device that emits electric, magnetic and/or electromagnetic signals. The electronic device is associated with includes one or more sensors that are capable of detecting the proximity of a transportation vessel. Upon detection of the proximity of a transportation vessel, the electronic device deactivates and/or decouples power to the field-emitting device and/or other systems of the electronic device so that the components of the electronic device can no longer emit signals that may interfere with the transportation vessel systems. The electronic device may reactivate and/or re-couple power to the field-emitting device if the sensor(s) no longer detects the proximity of a transportation vessel. The electronic device may also perform the reactivation and deactivation procedure if the electronic device detects a hazardous area.
