Abstract: Methods and apparatuses for performing ground-based flammable fluid drainage testing are provided. An apparatus for performing flammable fluid drainage testing on a test article includes a spine configured to receive a coupon; a first wall structure configured to engage the spine to form a first chamber; a second wall structure configured to engage the spine to form a second chamber opposite the first chamber; a nozzle device configured to spray a fluid into the first chamber and onto the coupon; a vacuum device configured to create a pressure differential between the first chamber and the second chamber; a leg mounting the spine to a base; and a shaker platform configured to apply an excitation input to the coupon.

Abstract: A cellular communication device uses manually operated airgap switches that selectively enable or disable various functions of the communication device. The airgap switches physically disconnect conductors associated with power or signal transmission so that the operator is assured that the disabled function is not vulnerable to software-based intrusions. The various functions may include GPS, NFC, Bluetooth, WiFi, and cellular wireless devices. The functions may also include transducers such as a camera or microphone. In other cases, the disabled functions may include sensors such as an accelerometer, gyroscope, or compass that may be used to create a dead-reckoning trail.
