    Abstract: An electronic module assembly has a memory module that includes a memory module and an electronic module. The memory module includes a first board having a first board first surface disposed opposite a first board second surface. The electronic module is operatively connected to the memory module. The electronic module includes a mounting plate having a mounting plate first surface that is disposed opposite a mounting plate second surface that faces towards the first board first surface. The mounting plate has a first post and a second post spaced apart from the first post.

    Abstract: An interface for mitigating electromagnetic interference (EMI) on a printed circuit board (PCB) is disclosed. The PCB can contain circuit components and includes one or more signal planes sandwiched between corresponding ground planes. The PCB has a first and second side and an interface region separating the first and second sides that includes a partition wall projecting outward from the interface region, configured for EMI shielding between the first side and second sides, one or more pairs of input and output pads straddling the interface region on respective first and second sides and configured to accommodate an EMI line filter, and a ground barrier within the printed circuit board under the interface region. A method of mitigating EMI using the interface is also disclosed.

    Abstract: Apparatus and associated methods are disclosed that relate to detecting a shaft condition of a gas turbofan engine. Shaft condition is detected based on sensed rotation rates of the shaft at different shaft locations. If the sensed rotations rates of the shaft at the two different shaft locations are indicative of a compromised shaft, such as, for example, a shaft that has sheared, then a fuel cut-off signal is generated. The fuel cut-off signal is then sent to a fuel cut-off valve so as to cut off the fuel supplied to the gas turbofan engine. In some embodiments, shaft condition is determined based on a difference between scaled rotation rates of the shaft at two different shaft locations.

    Abstract: Disclosed is an aircraft sensor fault detection system. The system includes a sensor system having a sensing apparatus to measure a parameter of an environment and a measurement circuit coupled to the sensing apparatus. The system includes a source of alternating current connected to the sensor system. The system further includes an alternating current measurement system that measures alternating current passing through the sensor system and indicates an error when a threshold based on a change in impedance of the sensing apparatus is exceeded.
