摘要： To prevent the capture and transmission of excluded data, the current pose and motion of a video camera are used to predict a pose and predicted FOV for the video camera over one or more future frames. The predicted pose and predicted FOV are used to generate cues to enforce an alignment condition to an allowed object or to prevent capture of a disallowed object. If the cues fail, an interrupt is generated to prevent capture of disallowed objects in the video signal and perhaps to deactivate the video camera. The predicted FOV prevents excluded data from entering the video signal and reaching circuitry or being processed downstream of the video camera. This can be implemented in real or near real time.

摘要： A synthesizer is provided having a controller configured to receive a first signal. A digital-to-analog converter (DAC) is coupled to the controller and configured to generate a voltage bias based on the first signal. The voltage bias corresponds to a target resonant frequency. A semiconductor laser is coupled to the DAC and configured to receive a second signal tone. The semiconductor laser generates a plurality of tone signals having octave multiples of a base sub-harmonic tone of the second signal tone.

摘要： A control surface restraining system for variably preventing movement of a control surface imparted by a control actuation shaft of a control actuation section of a tactical flight vehicle includes a power take-off shaft operably connected to the control actuation shaft with a power take-off gear train and a control surface restraint. The control surface restraint is configured to variably engage the power take-off shaft, thereby locking the power take-off gear train and preventing the control actuation shaft from imparting the movement of the control surface. The control surface restraint is also configured to variably disengage the power take-off shaft, thereby unlocking power take-off gear train and allowing the control actuation shaft from imparting the movement of the control surface.

摘要： An Array Core Block for an AESA includes a stack of 2*M alternating N- channel RFIC and MMIC Power Amplifier wafers bonded together by a wafer¬ scale direct bond hybrid (DBH) interconnect process. This process forms both metal-to-metal and dielectric hydrogen bonds between bonding surfaces to seal the wafer stack. Each array core block includes an array of through substrate metal vias to distribute DC bias, LO and information signals. Each array core block also includes a cooling system including micro-channels formed on a backside of at least one of the chips in each bonded pair and through substrate via holes formed through the stack that operatively couple the micro-channels for all of the bonded pairs to receive and circulate a fluid through the micro-channels and through substrate via holes to cool the RFIC and MMIC Power Amplifier chips and to extract the heated fluid.

摘要： A guidance system for a missile performs a method for guiding the missile. The guidance system includes a target detector (202) and a window (208) between a target (202) and the target detector. The window including a first pane, a second pane and a channel between the first pane from the second pane. Radiation (210) from the target passes through the window including the first pane, the second pane and the channel to be detected at the target detector. A gas is transported through the channel between the first pane and the second pane to control a temperature of the window.

摘要： A system includes and maintains a machine learning algorithm. The machine learning algorithm is trained to identify non-targets (210,211,212,213) in an environment. The system receives an image of the environment, and identifies the non-targets in the image using the trained machine learning algorithm. The system then generates a firing cut out map for overlaying on the image of the environment based on the identified non-targets (210,211,212,213) in the image of the environment.

摘要： A bulk acoustic wave, BAW,resonator includes a piezoelectric layer oriented so that an N-polar surface forms a frontside surface that faces away from the substrate while a metal-polar surface forms the backside surface and faces toward the substrate. A process for the manufacture of a bulk acoustic wave resonator includes orienting a piezoelectric layer on a substrate so that an N-polar surface forms a frontside surface that faces away from the substrate while a metal-polar surface forms the backside surface and faces toward the substrate; etching a via though the backside of the substrate to the metal-polar surface of the piezoelectric layer; and removing etch residue from a sidewall of the resonator cavity.

摘要： Methods and apparatus for a frequency selective limiter (FSL) having a magnetic material substrate that tapers in thickness and supports a transmission line that has segments and bends. The segments, which differ in width and are substantially parallel to each other, such that each segment traverses the substrate on a constant thickness of the substrate.

摘要： Apparatus and associated methods relate to using a plurality of antennas radially distributed about a rotatable turret to sequentially scan a field of view. Each of the plurality of antennas directs an electromagnetic beam and senses its reflection along a principal direction defined by a roll position of the rotatable turret and an azimuthal beam angle. The principal directions of the antennas have a unique azimuthal beam angle relative to a boresight (i.e., axis of rotation). As the turret rotates, each of these antennas is sequentially turned on at a first roll position and off at a second roll position. This enables electromagnetic beams generated by the antennas to pan a scene both in azimuth and roll. An image processor then determines, based on the reflected signals received by the plurality of antennas, directions to and/or velocities of objects within the scanned field of view.
