摘要： A vision-based navigation method that does not depend on GPS signal for landing AAM aircraft. The Vision-Based Approach and Landing System (VALS) uses images captured from a camera for Advanced Air Mobility (AAM) approach and landing in GPS-denied environments, which offers a potential Alternative Position, Navigation, and Timing (APNT) solution. VALS utilizes a computer vision algorithm called Coplanar Pose from Orthography and Scaling with Iterations (COPOSIT) to estimate the position and orientation of the camera based on coplanar features. VALS also includes an extended Kalman filter that uses IMU measurements in a prediction step and the COPOSIT estimation results in a correction element. Combining IMU with vision creates a sensor fusion navigation solution for GPS-denied environments.

摘要： Method of removing or adsorbing a target substance or material, for example a metal, non-metal toxin, dye, or small molecule drug), from solution by functionalizing a substrate with a peptide configured to selectively bind to the target substance or material and to bind to the substrate. Methods herein are useful for example for biomining applications. More specifically, the method employs metal-binding peptides to remove metals from solution, particularly aqueous solution. More specifically, the substrate is fungal mycelium. Fusion peptides and/or proteins containing metal-binding domain sequence and optionally containing substrate-binding domain sequence are provided. Fusion peptides/proteins containing a metal-binding domain and a chitin-binding domain are provided. Also provided are nucleic acids encoding fusion peptides and/or proteins containing metal-binding domain sequence and those further containing a substrate-binding domain, for example a carbohydrate-binding domain, and more specifically a chitin-binding domain.

摘要： A humidity sensitive material includes a lanthanum-doped barium titanate (BaTiO3) co-doped with an alkali hydroxide. A polymeric liquid binder is used as a vehicle to deliver the humidity sensitive material to a substrate or electrode via a 3D-printing process. The humidity sensitive material is highly sensitive to changes in humidity and exhibits rapid and large changes in capacitance and impedance for just a relatively small change in humidity. The humidity sensitive material exhibits significantly large changes in impedance and capacitance over the entire 10-90% RH range. As a result of the high sensitivity of the humidity sensitive material, the log-linear response is significantly easier to calibrate in humidity sensing devices that use the humidity sensitive material.

摘要： A non-aqueous fluidic system for extracting, filtering and concentrating lipid biomarkers from geological samples includes a sample input for receiving a sample, a combined comminution-extraction unit, a filter in fluid communication with the container, and a concentrator operable to receive the solvent phase from the filter and to concentrate lipid extracts for further analysis. The combined comminution-extraction unit has a container into which the received sample is introduced, a port through which one or more organic solvents are introduced into the container for mixing with the sample to thereby extract lipids into an organic phase, and a comminutor configured to rotate in the container to pulverize the sample to a uniform, reduced particle size and comprising a sonicator configured to agitate and disperse the sample into the one or more organic solvents.

摘要： A method of controlling a vehicle utilizing a controller having a vehicle model that corresponds to the vehicle. The method includes utilizing the controller to provide inputs during vehicle operation, and measuring vehicle outputs for a plurality of times while the vehicle is in operation. The method further includes determining modeling parameters of the vehicle model to thereby model vehicle behavior, wherein the modeling parameters are determined based upon the utilized inputs and the measured outputs. Predicted vehicle outputs for the plurality of times are determined, at least in part, by utilizing the determined modeling parameters. The system further includes determining a system error for the plurality of times utilizing a difference between the measured vehicle outputs and the predicted vehicle outputs. The vehicle model is modified to provide adaptive changes while the vehicle is in operation based, at least in part, on the system error.

摘要： A coil-on-plug (COP) exciter includes a COP and a housing configured to be coupled to and positioned at least partially between the COP and an engine. The COP exciter also includes an electrode core positioned at least partially within the housing. The electrode core has a first end and a second end. The first end is configured to be coupled to the COP. The COP exciter also includes an electrode tip configured to be coupled to the second end of the electrode core. A voltage is conducted from the COP, through the electrode core, and to the electrode tip, which generates a spark that is configured to energize a first propellant to start the engine.

摘要： A Rapid Aero Modeling program and process may be applied to computational experiments such as computational fluid dynamics (CFD) programs to obtain aerodynamic models which may be in the form of polynomial equations. The program and process may be utilized to estimate (develop) aerodynamic models appropriate for flight dynamics studies, simulations, and the like. Feedback loops are provided around computational codes to rapidly guide testing toward aerodynamic models that meet user-defined fidelity criteria. A user has the freedom to choose a specific level of fidelity in terms of prediction error, in advance of a CFD test (computation).

摘要： Described herein are highly thermally conductive hybrid carbon fiber composites. The composites are composed of one or more alternating layers of (a) a pyrolytic graphite sheet and (b) carbon fibers impregnated with a resin. The thermal conductivity of the composites is substantially higher when compared independently to the pyrolytic graphite sheet and carbon fibers. In addition to increased thermal conductivity, the composites possess other desirable properties such as increased thermal emissivity and solar absorptivity. The enhanced properties of the composites make them suitable for use in a number of different applications where heat flow is desirable.
