Abstract: The system and method for forming an ignition sequencer comprising two inseparable portions (a body and an armature) where an armature is articulable with respect to a body to allow for the existence of no less than two distinct stages of the ignition sequence through the articulating motion of the additively-manufactured armature. The ignition sequencer assembly architecture allows for installation of an internal energetic compound while all components are assembled and interconnected. The ignition sequencer assembly architecture allows for installation into a next higher-level assembly using a single, uniaxial, force.

Abstract: A disclosed apparatus and method reduce the likelihood of multiple bit single event upset (SEU) errors in space-deployed memory devices and memory macros, without requiring novel, specialized memory designs and without significant added cost or performance loss. For each memory, a bit selection layer effectively increases the mux of the memory bit table, thereby reducing the word size while increasing the word capacity, without changing the total memory capacity. As a result, the separation between the physical bit storage locations for each word is increased, thereby reducing the likelihood of multiple bit SEU errors. A buffer can be implemented if the memory lacks individual bit write control. The memory can be implemented in a core IC of an MCM-HIC, and the bit selection layer and/or buffer can be implemented in a chiplet or chiplets of the MCM-HIC.

Abstract: A fuze setter interface for substantially simultaneously and wirelessly transferring power and data between a fuze setter and fuze. The fuze setter interface includes separate power and communications interfaces. In the power interface, an induction coil is provided in each of the fuze setter and fuze. Power is transferred by magnetic field coupling between the induction coils. In the communications interface, a communications member is provided in each of the fuze setter and fuze, along with appropriate functions to generate alternating-current (AC) waveforms, and condition, modulate or demodulate signals. In one example, both communications members are induction coils that transfer data by magnetic field coupling. In another example, both communications members are radio-frequency (RF) transceivers that transfer data by radio signal. The RF transceiver in the fuze may be a Height of Burst (HoB) sensor. In another example, both communications members are optical transceivers that transfer data by optical signal.

Abstract: The system and method of using a debug interface recorder and replay unit for debugging and testing devices of interest such as integrated circuits by using a debug interface buffer controller to receive, record, and replay sequences of instructions to the integrated circuit. This is particularly useful for deployed devices that are difficult or dangerous to access. This is also beneficial for devices that cannot be reached (e.g., after launch). By recording sequences and storing them for later use, and by communicating commands and configuration settings to a device, system maintenance and troubleshooting is accomplished saving valuable time and money without requiring physical access to the device of interest.

Abstract: A light sensing apparatus includes: an arrangement of light sensing pixels, one or more pixels each associated with a noise floor and able to detect a triggering level of incoming light above the noise floor from a corresponding portion of a scene; readout circuitry to process and reset the triggering pixels; and an automatic gain control (AGC) to raise the noise floor of one or more pixels. Sometimes, the light sensing apparatus is part of a seeker that includes control circuitry to dynamically control the AGC to raise the noise floor of one or more pixels by an adjustable amount that varies in relation to the distance between the seeker and an intended target. Sometimes, the control circuitry dynamically controls the AGC in response to a concurrent triggering of two or more triggering pixels. or in response to a gain schedule corresponding to guiding the seeker to the intended target.

Abstract: A system for automatic prediction and generation of a Q-Code based on a text description provided in a NOTAM is provided. The present system may be utilized at a top level to generate a Q-Code from a text description or at a mid-level in the flight planning process to verify and/or confirm a human-generated Q-Code based on the text description in a NOTAM. Further, the present disclosure may allow for higher accuracy in the generation of Q-Codes thereby reducing the number of incorrect suboptimal and/or rejected flight plans produced by automatic flight planning systems.

Abstract: A spectrum sharing system includes an advanced beacon (e.g. a low latency RF link) as part of an information sharing subsystem. The advanced beacon signal carries radar spectrum transmission schedule in an obfuscated way such as not to reveal the geolocation of the radar. The information sharing subsystem directs nodes, such as cell phones, to share spectrum based on spectrum sharing instructions contained in the advanced beacon. The spectrum sharing system permits out-of-band sharing of spectrum white space, as well as sharing of in-band spectrum gray space.

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 tail kit assembly of a guided munition having a tail kit base connected to a trailing end of a projectile body. The tail kit base is rotatable relative to the projectile body. A trimmable rudder has forward and rearward ends. The forward end is pivotally coupled to the tail kit base, such that the trimmable rudder can, relative to the tail kit base, between retracted and extended orientations. An actuator is fixed between the tail kit base and the rearward end of the trimmable rudder. The actuator is electrically coupled to an onboard guidance system that controls actuation of the actuator to pivot the trimmable rudder between the retracted orientation and the extended orientation.

Abstract: Techniques are provided for geolocation of a radar emitting source. A methodology implementing the techniques according to an embodiment includes calculating time difference of arrival (TDOAs) of ground emitter radar pulses, within a dwell period, between two long baseline interferometer (LBI) antennas. The TDOA calculations are based on a precision estimate of the time of arrival of the radar pulses. The method further includes calculating an LBI phase wrap disambiguation factor based on (1) the TDOAs, (2) an average of frequencies of the radar pulses within the dwell period, and (3) an average of phase shifts of the radar pulses between the LBI antennas within the dwell period. The method further includes mapping a curve of points onto the surface of the earth based on an LBI cone angle calculation employing the LBI phase wrap disambiguation factor. The curve of points is associated with a geolocation of the ground emitter.
