Abstract: Selecting a control channel set in a communication system involves monitoring received signals to identify a plurality of nodes of interest (NOI) and determining Eb/N0 values for a plurality of control channels. For this purpose, a data metric and spectral data can be provided to the communication device by the respective NOI for which Eb/N0 values are being determined. A comparison is made of the Eb/N0 values for all NOI to select an optimal control channel set. The optimal control channel set is then used by the communication device to transmit the control channel information to the plurality of NOI.

Abstract: A method for mitigating interference in a frequency hopping channel system based on codeword metrics obtained during decoding of codewords. The method includes decoding a plurality of codewords using a particular error control coding method. Each of the plurality of codewords includes portions received from plurality of channels in the frequency hopping channel system. For each decoded codeword, one or more codeword metrics are obtained based on the cost of correcting errors during decoding of the plurality of codewords. Based on the codeword metrics, one or more channel metrics are inferred. Based on the inferred one or more channel metrics, a reliability metric of a particular channel is reduced, or incoming symbols received from the particular channel are ignored during decoding.

Abstract: A device, system, and/or method may be used to provide an adaptive alignment. A first video data may be received. The first video data may comprise a first video frame and a second video frame. Sensor pose data may be determined. The pose data may be associated with the first video frame and the second video frame. An adjusted video frame may be determined based on the first video frame and a motion indicated by the pose data. A frame adjustment value may be determined by comparing a first pixel from the adjusted video frame to a second pixel from the second video frame. The frame adjustment value may correlate the pose data to the first video data. A second video data may be determined by applying the frame adjustment value.

Abstract: An optical resonator may be provided. The optical resonator may comprise a laser system with an adjustable optical path length. The optical resonator may include a back mirror. The back mirror may include a first back mirror surface and a second back mirror surface. The first back mirror surface and may provide a first optical path length for the optical resonator if the first back mirror surface may be included in the optical path. The second back mirror may provide a second optical path length for the optical resonator if the second back mirror surface is included in the optical path.

Abstract: Network security anomaly detection systems and methods include a processor, in communication with the network, receiving network device status information. A variational autoencoder receives the device status information, optimizes the device status information, and determines whether the device status information qualifies as an anomaly. Optimized device status information is compared to either non-anomalous or anomalous device status data in a latent space of the variational autoencoder. The latent space preferably includes an n-D point scatter plot and hidden vector values. The processor optimizes the device status information by generating a plurality of probabilistic models of the device status information and determining which of the plurality of models is optimal. A game theoretic optimization is applied to the plurality of models, and the best model is used to generate the n-D point scatter plot in latent space. An image gradient sobel edge detector preprocesses the device status information prior to optimization.

Abstract: A radio frequency (RF) communication system may include a first radio and a second radio being relatively movable. The first radio may include an RF transceiver configured to operate on a selected RF channel from among a plurality of different RF channels, and a controller coupled to the RF transceiver. The controller may be configured to obtain historical RF spectral data over time, position and RF channel, as the first and second radios move relative to one another, determine at least one power null from the historical RF spectral data, and dynamically select an RF channel from among the plurality thereof based upon the at least one power null.

Abstract: An apparatus and method are provided for a night vision system that integrates functions of detecting an intensified image and transmitting the intensified image superimposed with a heads-up display. The night vision system includes an optical device having a transparent display configured with pixels emitting display light (i.e., the heads-up display), and the transparent display has transmission regions arranged among the pixels for transmitting light representing an intensified image (e.g., luminescent light from a phosphor screen). Light rays passing through the transmission regions also pass through detectors, which detect light outside of the visible spectrum (e.g., UV light). By detecting light outside of the visible spectrum, the detectors detect the intensified image without degrading the image in the visible spectrum that is provided to users.

Abstract: An apparatus and method are provided for a night vision system including a transparent overlay display that transmit direct-view light representing an intensified image and emits display light representing a display image. The overlay display includes photodetectors arranged to detect an intensity the incoming direct-view light, and an intensity of the display light depends on the detected intensity. In some embodiments, the intensity of the display light is spatially modulated using an amplitude or envelope of the intensity that is based on the detected local intensity of the direct-view light. In some embodiments, the intensity of the display light is adjusted to correct for loss of the direct-view light. The intensity of the display light may be controlled using control circuitry that receives signals from the photodetectors, and the control circuitry may be located on the same semiconductor chip as the overlay display.

Abstract: Methods and systems for non-contact temperature measurement of an object on which is attached or etched a diffraction grating. The diffraction grating expands and contracts as the object expands and contracts upon there being a change in temperature of the object. Upon a light beam being received on the diffraction grating, the diffraction grating produces a pair of complementary light beams and one of the light beams is reflected back onto the diffraction grating and then onto the other light beam in a manner that causes the reflected light beam to propagate alongside and non-parallel to the other light beam. The resultant two light beams are thereafter impinged onto a camera at respective first and second impingement locations. The temperature of the object is then determined based on the separation distance between the first and second impingement locations.

Abstract: Systems and methods for operating a communication device. The methods comprise: receiving a carrier signal modulated with a modulation signal comprising a symbol conveyed in a symbol timing window; determining an energy value for each timeslot in the symbol timing window; combining the energy values to determine a combined energy value for each bit of the symbol in a manner in which the combined energy value is penalized if more than one timeslot of the symbol timing window comprises energy contained in the carrier signal; and generating a soft value for each bit of the sequence of bits by combining the combined energy value with a weight value, where the weight value is selected from a plurality of weight values based on a number of timeslots in the symbol timing window which comprises energy contained in the carrier signal.
