Abstract: A power supply comprises: a transformer having a secondary winding to produce an alternating current at terminals of the secondary winding responsive to a switching current in a primary winding of the transformer; an output rectifier, coupled to the terminals and to an output node and a return node of the output rectifier to be connected to a load, including at least a first diode to rectify the alternating current and to supply a rectified current to the output node; and a first resistor (R)-inductor (L)-capacitor (C) (RLC) snubber (first RLC snubber) including a first resistor, a first inductor, and a first capacitor connected in series with each other, the first RLC snubber coupled to the output rectifier and the secondary winding to dampen voltage ringing in the output rectifier caused by the switching current.

Abstract: An apparatus comprising: a first circuit and a second circuit of a circuit configured to operate in a first mode and a second mode in which the first circuit dissipates more power than the second circuit and the second circuit dissipates more power than the first circuit, respectively; a coolant conduit with a first port and a second port and along which the first circuit and the second circuit are located nearer the first port and the second port, respectively; and a conduit switch network configured to deliver colder coolant to the first port or the second port, depending on which mode is active, such that the colder coolant flows through the coolant conduit and initially encounters whichever of the first circuit and the second circuit dissipates more power, then encounters whichever of the first circuit and the second circuit is not dissipating more power.

Abstract: A method of controlling a switching power supply comprises: generating a pulse train; applying the pulse train to a switching transistor of the switching power supply to cause switching of the switching transistor on and off to convert an input voltage applied to the switching transistor to an output voltage, which rises while switching the switching transistor on and off and falls while not switching the switching transistor on and off; and performing hysteretic voltage control of the output voltage by first controlling dropping pulses of the pulse train so that the output voltage remains between hysteretic voltage thresholds including an overvoltage threshold and an undervoltage threshold that is less than the overvoltage threshold.

Abstract: Systems and methods for detecting anomalies in aviation data communication systems (e.g., air traffic control surveillance systems), include a processor receiving device status information. A variational autoencoder receives and optimizes the device status information and determines whether it 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 sorting circuit includes: a stack of registers for storing a set of data values from a highest value to a lowest value; a set of comparators for substantially simultaneously comparing an input data value to the set of data values stored in the registers, where the comparators enable registers whose stored data values are less than the input data values to receive a replacement data value; and a set of multiplexers, each associated with a register in the stack to select the replacement data value when the register is enabled. The multiplexer selects the input data value to be the replacement data value if the register is the highest register in the stack currently storing a data value that is less than the input data value. Otherwise, the multiplexer selects the data value stored in the next-highest register in the stack to be the replacement data value.

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: Aspects of the present disclosure relate generally to night-vision systems and more specifically to an integrated flex circuit. One example illustrated herein includes a method of upgrading a night-vision system. The method may include attaching a flex circuit to an intensifier module, in which the flex circuit includes one or more light detectors. The method may include inserting the intensifier module into a housing and folding the flex circuit to expose the one or more light detectors.

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: 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 radio frequency (RF) communications system may include a first RF node that transmits data, including a new frequency of operation, and a sequence of pilot symbols spread with a complex spreading code sequence. A second RF node may receive an incoming signal from the first RF node and perform despreading for N sample offset delays to generate N despreading sequences for the sequence of pilot symbols. The second RF node may perform a cross-correlation to select a desired despreading sequence from the N despreading sequences, determine a phase offset and timing offset, process the incoming signal based upon the desired despreading sequence, phase offset and timing offset, and switch to the new frequency of operation.
