    Abstract: A communication system includes a laser that generates a laser light and a modulator that includes a modulation element configured to modulate the laser light with an input signal based on a bias voltage to produce an output signal. Control circuitry provides the bias voltage to a bias input of the modulation element and is configured to maintain a bias lock on at least two bias points of the modulation element during operation. The control circuitry is programmed to perform a bias lock operation that includes performing an initial voltage sweep on the modulation element and establish initial bias values for the at least two bias points. The circuit also providing a bias waveform to the bias input of the modulation element that varies over time and contains identifiable dither tones, determines harmonic power at the at least two bias points; and varies the bias waveform to determine harmonic power until the harmonic power is minimized to establish a bias lock with locked bias values.

    CPC classification number: G06N20/20

    Abstract: A method includes obtaining multiple machine learning models, where each machine learning model includes a backbone and a head. The method also includes selecting a first of the machine learning models to retain its backbone. The method further includes back-propagating error terms for synthetic activation data through at least a portion of the backbone of a second of the machine learning models to generate an inception basis set. In addition, the method includes configuring a bridge using the inception basis set, where the bridge is configured to translate features generated by the backbone of the first machine learning model into features for use by the head of the second machine learning model.

    Abstract: A radio frequency (RF) test probe adapter comprises a cable adapter operable for use with a RF test probe and a housing. The cable adapter comprises a cable connector configured to physically couple to a connector of a coaxial cable, a first pin operable to electrically couple a center conductor of the coaxial cable to a first lead of the RF test probe, and a second pin operable to electrically couple an outer conductor of the coaxial cable to a second lead of the test probe. The housing is sized and shaped to secure the RF test probe and the cable adapter in a physically coupled configuration.

    Abstract: An asymmetric ERA box improves the disruption of a shape-charge jet for a high-explosive projectile for a given mass requirement and stand-off distance. Mass is asymmetrically redistributed from the outer plate to the rear plate in the form of increased thickness of the rear plate. This is offset by forming the outer plate of a low-density material that provides an impedance mismatch sufficient to attenuate the shockwave of low velocity projectiles (e.g., 50 caliber bullets) so that they embed in but do not detonate the explosive. The outer plate provides negligible disruption of the shape-charge jet with substantially all the disruption being provided by the thicker high density rear plate. Placement of substantially all the mass toward the front of the shape-charge jet improves overall performance of the ERA. This asymmetric configuration provides the same performance as known symmetric ERA configurations against kinetic-energy projectiles as the total mass in the outer and rear plates remains essentially the same.

    Abstract: A technology for remote object imaging processing. An example of the technology can include calculating geographic coordinates for an object using in part a line-of-sight distance to the object from a camera coupled to a vehicle, calculating an angle of the sun relative to the object using sun position data that corresponds to a time and date and the geographic coordinates for the object, determining a white balance setting based in part on the angle of the sun relative to the object, and applying the white balance setting as a parameter used to process an image of the object captured using the camera coupled to the vehicle.

    Abstract: Devices, systems, and methods for removing non-linearities in an inverse synthetic aperture radar (ISAR) image are provided. A method includes estimating pitch and roll about range and doppler axes of a time series of ISAR images including the ISAR image, interpolating ISAR image data based on the estimated pitch and roll resulting in interpolated ISAR image data, and resampling based on the interpolated ISAR image data and the time series of TSAR images resulting in an enhanced image.
