摘要： Systems and associated methods for utilizing an artificial hair sensor to gather fluid flow data sensed on a surface. The artificial hair sensors are disposed on a surface to acquire flow sensory data in approximately real-time and for a plurality of dynamic flow parameters on the surface. The sensory data is based on a quantity of the artificial hair sensors that can be configured in an array of sensors. A mapping module, such as a neural network, is operatively coupled to the artificial hair sensor array and receives the sensory data acquired by the artificial hair sensors and generates a time-varying signal, which is based on the quantity of dynamic parameters. A real-time representation of the time-varying signal is generated.

摘要： A method for automatically identifying the source of fluctuations in a trans-ionospheric radio signal, by acquiring a portion of the radio signal and computing statistics on it, including mean, standard deviation, scintillation index, skew, kurtosis, decorrelation time, and spectral slope. The scintillation index, skew, kurtosis, decorrelation time, and spectral slope are compared to thresholds, and based at least in part upon the comparisons, at least one condition present in the portion of the radio signal is selectively indicated to an operator, where the condition is selected from the group of no signal fluctuations, RF interference, multipath interference, noise, and ionospheric scintillation.

摘要： A broad area quantum cascade laser includes an optical cavity disposed between two sidewalls, the optical cavity including an active region for producing photons when a current is applied thereto, where the optical cavity is subject to a presence of at least one high order transverse optical mode due to its broad area geometry. The broad area quantum cascade laser may also include an optically lossy material disposed on at least a first portion of one or more of the two sidewalls.

摘要： Systems and methods of embodiments provide a feasible approach to implementing Far-Field Radiated Emission Design (FFRED) techniques suitable for simultaneous transmission of radar and communication signals. A set of signals for transmission and a transmission direction for each signal of the set of signals may be determined. The set of signals includes at least a first signal associated with a first transmission direction and a second signal associated with a second transmission direction that is different from the first direction. An optimization problem is configured based on characteristics of an antenna array and the set of signals and then solved to identify a set of waveforms suitable for transmitting the signals. The set of waveforms may include at least two waveforms, each of the at least two waveforms configured for transmission by a different antenna element of the antenna array. The determined waveforms may be coherent in the far-field and suitable for power efficient transmission.

摘要： A method of making a reconfigurable antenna comprises the steps of applying one or more first layers of a prepreg laminate fabric to a form having a desired contour; applying a pattern corresponding to an antenna shape to the first layers of prepreg fabric; applying one or more second layers of the prepreg laminate fabric atop the pattern to form a laminate stack; curing the laminate stack; and removing the pattern to form channels in the antenna shape. The desired contour may be an aircraft skin panel or an airfoil panel. The pattern may be a polymer sheet with an applied cPLA antenna design. The curing step may be performed in a vacuum bag under the application of vacuum and heat. The removing step may be performed by heating the cured laminate stack to remove the pattern.

摘要： A countersink go/no-go gauge is configured to aid a determination of whether a countersink aperture for a rivet is formed to a desired depth. The countersink go/no-go gauge includes a head having a depth defined between a top surface and a bottom surface and a shaft extending from the top surface of the head. The depth of the head is substantially equal to a desired depth of a countersink aperture. In some embodiments the go/no-go gauge includes tolerance features to provide a range for an acceptable countersink depth.
