摘要： Method and systems are disclosed for training state-classifiers for classification of cognitive state. A set of multimodal signals indicating physiological responses of an operator are sampled over a time period. A depiction of operation by the operator during the time period is displayed. In response to user input selecting a cognitive state for a portion of the time period, the one or more state-classifiers are trained. In training the state-classifiers, the set of multimodal signals sampled in the portion of the time period are used as input to the one or more state-classifiers and the selected one of the set of cognitive states is used as a target result to be indicated by the one or more state-classifiers.

摘要： A method for recognizing infrasound events includes detecting infrasonic source using one or more microphone arrays each having three equally-spaced infrasound microphones. The method includes identifying, via a data acquisition system (DAS), a level of coherence of the detected infrasonic acoustic signals from each possible pair of microphones and recognizing the infrasound source using the coherence and a time history of the detected signals. The method may include estimating source properties via the DAS, including a magnitude, azimuth angle, and elevation angle, and executing a control action in response to the estimated properties. A system includes the array and the DAS. The array may be positioned above or below ground, and may be connected to one or more aircraft in some embodiments.

摘要： Methods and systems are disclosed for deriving quantitative measurements of an imaged material using plenoptic imaging. In one or more embodiments, image data is generated by a plenoptic camera having a filter configured to transmit a plurality of different spectra in different regions of the filter. A set of plenoptic image data is produced by determining respective sets of pixels in the image data corresponding to the different regions of the filter and determining light intensities of the plurality of different spectra for respective super-pixel groups of the pixels in the image data. One or more additional quantitative measurements of an imaged material are then derived from a comparison of the determined light intensities of two or more of the plurality of different spectra.

摘要： A stretchable mesh material extends across the opening of a cavity of the landing gear of an aircraft when the landing gear is in the deployed position. The mesh material alters the flow of air across the opening of the landing gear cavity and significantly reduces the amount of noise produced by the wheel well at low-to-mid frequencies.

摘要： An optical device with a light source and a detector is provided. A digital micromirror device positioned between the detector and the light source may deflect light beams projected from the light source. An aperture in front of the detector may block an incoming light beam from the detector when the incoming light beam is incident on the detector outside of a passable incident range and including an aperture opening configured to pass the incoming light beam to the detector when the incoming light beam is incident on the detector within a passable incident range. The digital micromirror device may rotate between a first position causing the light beam to pass through the aperture opening and a second position causing the light beam to be blocked by the aperture. The optical device may be configured to operate as a shutter, chopper, modulator and/or deflector.

摘要： A method of monitoring a curing process for fiber reinforced composite materials that includes positioning an actuator on uncured composite material at a first location. At least one sensor is positioned at a second location that is spaced apart from the first location. The actuator excites waves in the composite part at the first location. At least one sensor is positioned at a second location that is spaced apart from the first location. The actuator excites waves in the composite part at the first location. The waves propagate through the composite part due to internal reflection. At least one wave metric is measured at the second location utilizing the sensor. At least one parameter of the curing process may be adjusted based, at least in part, on a wave metric measured by the sensor.
