    Abstract: Techniques are provided for a multi-frequency sampling system. A system implementing the techniques according to an embodiment includes a first bandpass filter to filter a radio frequency (RF) signal to generate a first filtered signal in a first frequency band, and a second bandpass filter to filter the RF signal to generate a second filtered signal in a second frequency band. The system also includes a first analog to digital converter (ADC) operating at a first sampling frequency to convert the first filtered signal to a first digital signal and a second ADC operating at a second sampling frequency to convert the second filtered signal to a second digital signal. The first frequency band is selected to avoid a first Nyquist boundary zone associated with the first sampling frequency and the second frequency band is selected to avoid a second Nyquist boundary zone associated with the second sampling frequency.

    Abstract: The present disclosure provides a system and method for determining a range to an object in a fluid. The system includes a polarized light source directed to the object in the fluid, a first imaging sensor, a second imaging sensor, and at least one processor. The at least one processor characterizes a depolarization rate of the fluid and determines the range to the object. The method includes generating polarized light via a polarized light source, polarizing an imager relative to the polarized light, transmitting the polarized light from the polarized light source into the fluid, receiving reflected light from the object, characterizing a depolarization rate of the fluid, based, at least in part, on the reflected light, and determining the range to the object, based, at least in part, on the depolarization rate of the fluid.

    Abstract: Nosecone and tailfin designs for aerodynamic systems are disclosed. The designs increase the usable volume within the fuselage of the aerodynamic system while still maintaining the same length for the aerodynamic system. In an example, the nosecone is truncated and includes a blunted tip compared to standard nosecone designs, which allows for more useable space along the length of the aerodynamic system. A tailfin structure is fabricated as a separate piece (separate from the fuselage of the aerodynamic system) and slips over a portion of one end of the fuselage, thus allowing useable volume within the fuselage beneath the tailfin structure. The tailfin structure also includes a hollow cavity for holding componentry (e.g., an RF transmitter, receiver, or transceiver device) with wires that feed through the tailfin structure and into the fuselage of the aerodynamic system.

    Abstract: A dynamic controlling framework that is adapted to dynamically optimize existing routing decisions in an optimized link state routing (OLSR) platform to favor higher-bandwidth, lower-latency links in the active link database. The dynamic controlling framework includes a link probing tool that is in communication with OLSR platform where the link probing tool is adapted to dynamically measure estimated bandwidth, latency scores, or both estimated bandwidth and latency scores of active links in the active link database of the OLSR platform. The dynamic controlling framework includes a plug-in framework that is in communication with the OLSR platform and the link probing tool where the plugin framework is adapted to receive at least one link quality multiplier (LQM) metric computed by the link probing tool and to combine the at least one LQM metric with the OLSR platform's existing link quality (LQ) metric for enhancing route selection by the OLSR platform.

    Abstract: The system and method of a steering a moving object using a control plate-based control actuation system on the moving object. The control plate-based control actuation system having a control plate with at least four fin linkages for connecting at least four fins to the control plate; and three actuators configured to move the control plate to produce movement in two or more of the at least four fins. The system produces roll, pitch, and yaw moments for the moving object using three actuators acting on the control plate and thus moving two or more of the at least four fins all with no loss of performance as compared to systems with four actuators.
