Abstract: A ring oscillator circuit is disclosed. The ring oscillator in one embodiment includes an odd number of inverters connected in a loop fashion, a current mirror having a drain of a first transistor connected to the inverters, and a self-biased inverter connected to a drain of a second transistor of the current mirror.

Abstract: Techniques are provided for implementing a portable spectrum analyzer. An example system, according to an embodiment, includes a signal analyzer including an RF receiver to receive RF signals from an antenna, an analog-to-digital converter to generate a sampled signal based on the received RF signals, and a signal analysis co-processor to perform cognitive scanning analysis of the sampled signal. The cognitive scanning analysis includes detection, identification, and characterization of digital/analog signal(s) embedded in the sampled signal. The system may further include a communications interface circuit to provide communication between the signal analyzer and an associated mobile host platform (e.g., smartphone). The communication includes transmitting results of the cognitive scanning analysis to the mobile host and receiving parameters from the mobile host to control the operation of the cognitive scanning analysis. The signal analyzer and mobile host are coupled through a shared enclosure such as a hinged case, sleeve, or wallet.

Abstract: A system and method for cooling electronics with compressed gas cylinders. A small, lightweight, scalable cooling system provides portability and cooling for electronic components in remote areas. In some cases one or more compressed gas cylinders are used with a metering valve and a temperature sensor to release gas into an expansion chamber or channels in thermal contact with a heat sink that is in thermal contact with an electric component.

Abstract: The system and method of implementing a high reliability flash memory recorder comprising warm spare and error code correction bytes across several multi-chip modules. The use of redundant field programmable gate arrays and/or processors for command and control increases redundancy. The system and method has lookup table-based mechanisms combined with programming to determine when to substitute a warm spare byte as well as when to declare a block of memory as “bad” and no longer to be used. The system may use multiple memory banks with power switching per bank to reduce power consumption as well as increase reliability when the array is not being accessed.

Abstract: A battery door assembly for a battery compartment is disclosed. The battery door assembly includes a battery cover, glide track, a spring-loaded button, a locking tab and a set of hinges. The set of hinges is pivotally connected to a chassis of a scope. The locking tab keeps the battery cover from opening. The battery cover can be unlocked by first applying pressure on the spring-loaded button, and then sliding the spring-loaded button and the locking tab from one end of the glide track to another end of the glide track while maintaining the applied pressure on the spring-loaded button.

Abstract: The Quad Cell permits measurement of four quadrant signal powers simultaneously, metrics which are equal when the laser spot is at the desired zero location, at the center of the cell, the origin of the cells' axes. A control action acts upon the Quad Cell signals to move the laser spot toward the origin of the axes bisecting the four quadrants of the cell, moving the laser spot to the origin to achieve a null in the difference between these four signal levels.

Abstract: A method for vision-aided navigation which utilizes an image registration system to update a navigation control system. One exemplary feature of the method includes the use of Enhanced Phase Correlation techniques to create a reference imagery database and register images against the created database. The method may be operated on a non-transitory computer-readable medium storing a plurality of instructions which when executed by one or more processors causes the one or more processors to perform the method for vision-aided navigation which utilizes an image registration system to update a navigation control system.

Abstract: The system and method of guiding an autonomous vehicle and/or mapping a target in 3D space using a digital light processing array and a laser with a wide field of view. The variability of the digital light processing array allows for adjustment of image resolution to account for range, weather conditions, and attitude of the target. Coupled with a learning AI system, an unmanned vehicle can offer superior tactical flexibility in the operational environment.

Abstract: A laser warning receiver system and method having at least four optical components mapped to a photodetector array to provide for omnidirectional detection of incident laser light. In some cases, a fifth optical component is mapped to the central portion of a photodetector array to provide hemispheric detection of laser light. The laser warning receiver system is configured to detect laser light in the NIR, SWIR, MWIR, and/or LWIR range using a single photodetector array and ROIC.
