Abstract: A grasp assist system includes a glove, finger saddles attached to a respective glove finger, one or more tendon actuators, and artificial tendons. The saddles have a rectangular body partially circumscribing a respective glove finger. Each saddle includes end lobes at opposite distal ends of the body. A first end of each tendon is secured to one of the tendon actuators. A second end forms a triple Brummel loop defining a main loop and two anchor loops. The anchor loops are disposed around the lobes. The saddles may form a rounded, double-headed arrow shape that is at least double the thickness of the body. The finger saddles are anisotropic, with different bending strengths depending on the axis, and may be constructed of thermoplastic polyurethane-coated nylon. Flexion and/or contact sensors and a controller may be used. A method of connecting the tendon actuator to the finger is also disclosed.

Abstract: A radio-frequency identification (RFID) antenna assembly, per an implementation, includes a number of multiplexer modules coupled with one another. Radio frequency (RF) signals are received from an RFID reader. One or more of the multiplexer modules has a switch with multiple output ports. An antenna connects with one of the output ports and, per an implementation, an encoder connects with another of the output ports. The multiplexer module(s) may also have a first rectifier for rapid self-powering capabilities, and a second rectifier for more robust self-powering capabilities.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
