Abstract: A scannable-latch random access memory (SLRAM) is disclosed. The SLRAM includes two rows of memory cells. The SLRAM includes a functional data input, a scan data input, a first and second functional data outputs, a scan data output, and a scan enable. The functional data input is connected to a first memory cell in a first and second rows of memory cells. The scan data input is connected to the first memory cell in the first or second row of memory cells. The first and second functional data outputs are connected to a last memory cell in the first and second row of memory cells, respectively. The scan data output is connected to the last memory cell in the first or second row of memory cells. The scan enable allows data to be output from the scan data output or the first and second functional data outputs.

Abstract: An F-theta lens provides more than 88 degrees FFOV, F #2.8 or less, length not more than 200 mm, and/or 2.5 μm or better resolution, with color correction from 450 nm to 650 nm. The lens includes three optical groups having positive, negative, and positive optical powers respectively, which can include four, four, and six elements, respectively. Embodiments include an aperture stop in the center of the second optical group. Refractive indices and ray heights are selected to correct for field curvature. Embodiments further include a CMOS detector having pixel pitch of 1.25 microns or less, density of 18 megapixels or more, focal plane diameter of 57.2 mm or more, Nyquist sampling of 400 lines per mm or more and wide pixel field of view of 30° or more. A plurality of CMOS detectors can be arrayed to create a mosaic image.

Abstract: The system and method for accurately determining range-to-go for a time-delayed command detonation of a projectile. Using dual laser and/or radio frequency detectors on the tail and on the nose of a spinning projectile to determine the range-to-go, time-to-go, and/or lateral offset from the projectile to the target. A time to detonation clock is used to determine when a projectile transitions from an exterior to an interior of a structure such that the projectile can more accurately detonate within a fixed structure.

Abstract: A multiple resolution focal plane array, the multiple resolution focal plane array having a plurality of bolometers and a readout integrated circuit connected to the plurality of bolometers, wherein the readout integrated circuit is configured to accumulate signal-induced current collected from each bolometer during an integration interval and then transfer the resultant signal onto output taps for readout. The readout integrated circuit is configured to allow a selection between at least two bolometer configurations, a first configuration where bolometers are combined into pixels comprising N×N series/parallel groupings of bolometers and a second configuration where the bolometers are used individually, forming pixels comprising only a single bolometer.

Abstract: A network defense system can include a sensor alert ingestion framework adapted to monitor network activity and alert detected or suspected anomalies. A network analyzer may be coupled to the sensor alert ingestion framework to analyze the anomalies. A course of action (CoA) simulator may be coupled to the network analyzer adapted to generate a list of decision including courses of action to address the anomalies. There may be a training and feedback unit coupled to the CoA simulator to train the system to improve responses in addressing future anomalies.

Abstract: Techniques are disclosed for providing a secure computational platform that facilitates collaboration of assets from different asset providers without exposure of the assets to threats. The assets may be in the form of tools, models, simulations, and other computational assets, which can be used, for example, to perform trade studies. The secure computational platform provides for integration of the assets in a workflow, while protecting the assets during construction and execution of the workflow. In some instances, each asset in the workflow is executed in an IT infrastructure of the asset provider to which the asset belongs.

Abstract: An optical assembly is part of an optical system such as a laser communication system on a moveable platform that operates in a range of temperature extremes. The optical assembly has a mount with a plurality of supports that couple an optical mirror to a frame or chassis of the optical system. The supports may be selectively heated or cooled in accordance with their respective coefficients of thermal expansion to reduce, minimize, or eliminate angular drift of the mounted optic or mount. The supports expand or contract to correct for misalignments of the beam reflection angle to improve the accuracy and efficiency of the optical system without significantly increasing size, weight, and power of the optical system.

Abstract: Systems and methods for testing or correcting optical pointing systems are disclosed. An optical pointing system may include an imaging sensor including a field-of-view (FOV) carried by the optical pointing system, at least one collecting device for collecting optical photons and directing the optical photons to the imaging sensor, at least one directing device for directing the at least one collecting device to different pointing vectors, and at least one non-transitory computer-readable storage medium carried by the optical pointing system having instructions encoded thereon that when executed by at least one processor operates to test the optical pointing system by, inter alia, determining a pointing error based, at least in part, on a macro image of a targeted object.

Abstract: A wireless receiver and method of wireless communication determines levels of noise, including interference, in communication channels without need of calibration. A digital test signal is digitally added to digitized noise, and a signal-to-noise-and-interference (SNIR) value is determined from a resulting bit error rate and/or message error rate. The level of noise is then determined from the SNIR. The amplitude of the digital test signal is adjusted to cause the SNIR to be sensitive to the noise level, which can require an SNIR between 1 dB and 10 dB. The system can include a digital test signal generator, or the digital test signal can be stored in a memory. The system can further include a channelizer, demodulator, data correlator, decryptor, and message assembler. Noise and interference level determinations can be used to select an optimal communication channel, and to adjust a transmission power and/or rate to suitable values.
