Abstract: A rotary machine, such as a turbomachine of a gas turbine engine, for example, including a rotor and a rotor seal assembly. The rotor is rotatable about a rotational axis and has a rotor seal face. The rotor seal assembly includes a seal body, one or more primary fluid conduits formed in the seal body, and a retraction assembly. The seal body has a seal face and is positionable to form a fluid-bearing gap between the seal face of the seal body and the rotor seal face. The one or more primary fluid conduits are fluidly connected to the fluid-bearing gap to supply a fluid to the fluid-bearing gap. The retraction assembly is connected to the seal body to move the seal body in a retraction direction away from the rotor seal face.

Abstract: An apparatus for detecting a condition or authenticity of one or more electronic devices includes an enclosure having an antenna integrated therewithin, a fixture mounted within a hollow interior of the enclosure, the fixture being configured to receive the one or more electronic devices and connect one or more signals to each of the one or more electronic devices and a sensor and controller assembly connected to the antenna and configured to process a signature of an emission of a radiofrequency (RF) energy from of one or more electronic devices having the one or more signals connected thereto.

Abstract: A device and method to test microelectronic parts to determine whether the parts are compromised by active illumination in a testing fixture within a shielded enclosure by analysis of emission metrics. The testing fixture can include a first layer with a capacitive member and a second layer with a cavity to receive a microelectronic part. A filter in a transmission chain can pass a high power signal to the fixture. A filter in a receving chain can pass a low power signal to the analysis unit.

Abstract: An apparatus for testing, inspecting or screening an electrically powered device for modified or unmodified hardware, firmware or software modifications including Malware, Trojans, adware, improper versioning, worms, or virus and the like, includes an antenna positioned at a distance from the electrically powered device and a signal receiver or sensor for examining a signal from the electrically powered device. The receiver or sensor collects unintended RF energy components emitted by the electrically powered device and includes one or more processors and executable instructions that perform analysis in a response to the acquired signal input while the electrically powered device is active or powered. The characteristics of the collected RF energy may be compared with RF energy characteristics of an unmodified device. The comparison determines one of a modified, unmodified or score of certainty of modified condition of the electrically powered device.
