Abstract: A guided projectile including a precision guidance munition assembly utilizes angular rate sensors to sample a first angular velocity of the precision guidance munition assembly from the first angular rate sensor at a first time, sample a second angular velocity of the precision guidance munition assembly from the second angular rate sensor at the first time, generate a coning command based, at least in part, on the first angular velocity and the second angular velocity, and apply the coning command to the canard assembly. The range may be decreased or increased based on the coning commands.

Abstract: A battery mounting mechanism that allows for one or more battery assemblies to be mounted in various positions within a vehicle via a securely attached mounting assembly that may allow for quick and easy adjustment of the position of the battery assemblies while further preventing rotation of the battery assemblies. Further provided herein is a mechanism for connecting multiple battery assemblies into a single battery unit while still allowing these battery assemblies to take advantage of the battery mounting mechanism provided herein.

Abstract: A system for a synchronous high speed shutter for sensor protection comprising a shutter disk having a rotational axis; wherein the rotational axis of the shutter disk is perpendicular to an optical axis of the sensor. A plurality of paired reflecting elements on the shutter disk, perpendicular to a surface of the shutter disk, wherein a polished surface of each of the plurality of paired reflecting elements is figured to match an angle (f #) of an incoming ray bundle; whereby incoming radiation is directed back out collecting optics; wherein the sensor comprises a single photon Geiger mode detector, and whereby the sensor is protected from damage by over-current due to a flood of photons.

Abstract: The system and method for hyperspectral target identification provides for sue of a sensor array such that for a 2 by 2 pixel, each pixel is set to a different wavelength by employing a band pass filter, so that one can determine whether a cluster set is of a natural object or a man-made object. Using ratios of the collected energy within the partitioned sub-bands one can make near real-time declarations about targets and in some cases, friend or foe determinations.

Abstract: A storage system is configured to facilitate memory operations with the memory that avoid the need for defragmentation. The system includes one or more memory devices and a memory interface operatively coupled with the one or more memory devices. The memory interface includes a start page module that provides a start page table having a page number that includes a first part of a corresponding dataset. A link page module of the memory interface provides a link page table that indicates an address for a current page of a given dataset and an address for a next page of the given dataset. Write/read page modules of the memory interface provide write/read page tables that include sub-addresses of a page where a portion of a corresponding dataset is being written/read. The memory interface executes data read, write, and erase operations that are tracked using the tables provided by the various modules.

Abstract: Techniques are provided for tracking of signals. A methodology implementing the techniques according to an embodiment includes filtering a first segment of an input signal, associated with a first time interval, into a first plurality of frequency bins. The method also includes detecting a signal of interest (SOI) in one of the first plurality of frequency bins. The method further includes filtering a second segment of the input signal, associated with a second time interval, into a second plurality of frequency bins. The method further includes determining movement of the SOI from a first frequency bin, of the first plurality of frequency bins, to a second frequency bin, of the second plurality of frequency bins. The method further includes tracking the SOI based on the movement determination. In some cases, the method further includes creating a composite signal based on the tracking over multiple frequency bins and multiple time intervals.

Abstract: Techniques are provided for tuning over a broad radio frequency (RF) bandwidth. A tuner implementing the techniques according to an embodiment includes an input module compromising a single-conversion superheterodyne receiver to convert a first RF signal to a processed RF signal by frequency translating from a first frequency range to a lower second frequency range. The input module is also configured to receive a second RF signal occupying the second frequency range and provide the second RF signal as a pass-through RF signal. The tuner also includes a down-conversion module to convert the processed RF signal to a first intermediate frequency (IF) signal by frequency translating the processed RF signal from the second frequency range to a lower third frequency range, and to convert the pass-through RF signal to a second IF signal by frequency translating the pass-through RF signal from the second frequency range to the third frequency range.
