摘要： A non-uniformity correction (NUC) calibration method comprises obtaining image data for a plurality of images with an image sensor, wherein each image in the plurality of images is obtained at a different respective global pixel gain setting and global expose in the image sensor; and using the image data for non-uniformity correction calibration to compute pixel NUC values for the pixels in the image sensor. The method can further include storing the pixel NUC values and obtaining further image data corrected by the stored pixel NUC values. In embodiments, the method can include moving a platform based on the further image data. In certain embodiments, the platform can be a guided munition.

摘要： A method is provided for sensing proximity of a target. The method includes sensing inductance associated with a magnetic field, wherein the inductance is affected by the target when the target is proximate the magnetic field. The method further includes providing the sensed inductance for processing. The processing includes determining an inductance value from at least the sensed inductance and estimating a parameter of a gap between a location of sensing the inductance and the target as a function of the inductance value and application of a nonlinear model of a relationship between the gap and inductance.

摘要： A method of identifying a viral compound, which includes modulating a narrow linewidth laser over a range of frequencies to provide a modulated optical signal that includes a single optical sideband, optically focusing the modulated optical signal with the single optical sideband at a viral sample to excite the viral sample and stimulate an emission of photons therefrom, and detecting amplification of the optical sideband emanating from the viral sample indicating an emission of photons at an acoustic resonance of the viral sample.

摘要： A method includes forming a first image of a scene through a static coded aperture onto a sensor with the static coded aperture in a first position relative to the sensor, shifting the coded aperture to a second position relative to the sensor, and forming a second image of the scene through the static coded aperture onto the sensor with the static coded aperture in the second position. Two or more images can be formed in this way. The method includes forming a combined image by deconvolving the two or more images and combining data from the two or more images into the combined image. The combined image can be a more accurate representation of the scene than either of the first and second images.

摘要： A system and method includes a structural body, a plurality of structural health monitoring (SHM) sensors, and first and second computer systems. The structural body includes a plurality of structures. The SHM sensors are configured to sense structural health data for a plurality of zones of the structures. The first computer system is configured to collect the structural health data from the SHM sensors. The second computer system includes a display and is configured to receive the structural health data from the first computer system and groups the zones into a plurality of structural regions, and groups the plurality of structural regions into at least one structural area. The display is configured to provide a visual representation of a structural region health of a first one of the plurality of structural regions based on the structural data for respective ones of the zones within the first one of the plurality of structural regions.

摘要： Apparatus and associated methods relate to generating a frequency spectrum weighting function for use in estimating a rotational frequency of the rotating member. The estimation of the rotational frequency is based on vibrations sensed by an accelerometer remotely located from a rotating member. The frequency spectrum weighting function is generated by a supervised learning method. The method includes receiving a set of test vectors. The test vectors include a rotational frequency value of the rotating member and a vibrational frequency spectrum corresponding to vibrations propagated to the accelerometer. The vibrations include vibrations caused by the rotating member rotating at the rotational frequency. The method includes calculating a test weighting function, and then weighting the vibrational frequency spectra by the test weighting function. The method includes calculating a vector score indicative of whether the weighted vibrational frequency spectra promote the identification of the rotational frequency of the rotating member.
