3D-Printable artificial muscles based on microfluidic microcapacitors
(The United States of America, as represented by the Secretary of the Navy, Washington, DC (US), 2024-01-23) Kartalov, Emil Paskalev; Coltelli, Michelangelo; Catterlin, Jeffrey; Research and Sponsored Programs Office (RSPO)
A microcapacitor array for providing artificial muscles is described. The microcapacitor array includes a dielectric body with electrode chambers, positive electrodes in positive electrode chambers, the positive electrodes being connected by a first set of channels in the dielectric frame; negative electrodes in negative electrode chambers, the negative electrodes being connected by a second set of channels in the dielectric frame. The first and second set of channels are arranged so that application of a voltage differential between the positive electrodes and the negative electrodes generates an attractive force between each set of adjacent positive and negative electrodes.
Quantitative Quality Assurance for Mixed Reality
(The United States of America, as represented by the Secretary of the Navy, Washington, DC (US), 2021-10-05) Angelopoulos, Christopher James; Greunke, Larry Clay; Research and Sponsored Programs Office (RSPO)
The invention relates to quantitative quality assurance in a mixed reality environment. In some embodiments, the invention includes using mixed reality sensors embedded in a mixed reality device to detect body positional movements of a user and using an indirect measuring device to determine a target location for the current state of the target equipment and a current subtask of a predefined workflow. The invention further includes using a direct measuring device associated with the target location to detect a user interaction by the user at the target location, determining a confidence value based on the user movements, the current subtask, and the user interaction, and displaying confirmation of the user interaction on a mixed reality display of the user.
Solid State Circuit Breaker with Reduced Clamping Voltage
(The United States of America, as represented by the Secretary of the Navy, Washington, DC (US), 2024-01-30) Zhang, Di; Research and Sponsored Programs Office (RSPO)
A solid state circuit breaker that may include a metal oxide varistor (MOY) that is connected in series to a thyristor, the MOY to clamp voltage of current flowing through the solid state circuit breaker; the thyristor including a gate to control flow of the current to the MOY along a first path to the MOY; a breakover diode to activate at a target voltage level to allow the current to flow to the MOY along a second path; and a Zener diode to close the gate and allow current to flow along the first path in response to the current on the second path.
Spherical Autonomous Underwater Vehicle
(The Government of the United States of America, as represented by the Secretary of the Navy, Washington, DC (US), 2024-07-09) Eldred, Ross Anthony; Lussier, Jonathan; Office of Research and Innovation
The invention relates to an autonomous underwater vehicle (AUV ). The AUV includes a frame and tunnel thrusters for propelling and orientating the AUV, where the tunnel thrusters have inlets and outlets, each of outlets being directed in a different orientation, and are mounted to the frame. The AUV further includes fasteners for connecting the frame to a hull, where the fasteners have an orientation that is substantially parallel to the tunnel thrusters. The hull has a substantially spherical shape and further includes (1) a bottom plate with inlet openings, (2) a top plate with outlet openings, where the top plate and the bottom plate are affixed to the fasteners and hold plate rings of the hull in place, and (3) each of the plate rings that further includes a corresponding retention ring and corresponding central plates.

Method And System for Optimal Trajectory Path Tasking for an Unmanned Aerial Vehicle (UAV)
(The United States of America, as represented by the Secretary of the Navy, Washington, DC (US), 2023-02-07) Ross, Isaac M.; Proulx, Ronald J.; Karpenko, Mark; Research and Sponsored Programs Office (RSPO)
A method and system for generating an optimal trajectory path tasking for an unmanned aerial vehicle (UAV) for collection of data on one or more collection targets by a sensor on the UAV.
Autonomously Deploying Effects on Water Body Bed
(The United States of America, as represented by the Secretary of the Navy, Washington, DC (US), 2024-02-20) Price, Christopher M.; Leary, Paul R.; Bingham, Brian S.; Office of Research and Innovation
The invention relates to a payload frame for deploying a payload underwater. The payload frame includes at least three lead screws, each lead screw connected near a top end of the lead screw to the payload by a corresponding spherical bearing; at least three motors, each motor connected to a bottom end of one of the lead screws, the motor to rotate the lead screw through the corresponding spherical bearing; at least three feet, each foot attached to one of the motors, the feet to support and secure the payload frame on a water body bed; an accelerometer attached to the payload, the accelerometer to measure gravity vectors of the payload; and a microcontroller connected to the accelerometer and the motors. The microcontroller to receive the gravity vectors from the accelerometer and control each of the motors based on the gravity vectors to position the payload in a target orientation.
Systems, methods, and apparatuses for determining the distance between two positions
(The United States of America, as represented by the Secretary of the Navy, Washington, DC (US), 2020-03-10) Romano, Marcello; Restaino, Sergio; Helmboldt, Joseph; Research and Sponsored Programs Office (RSPO)
Systems, methods, and apparatuses for determining the distance between two positions are disclosed. The system includes a correlator, a first receiver, and a second receiver. The first and second receivers each include: an antenna, a steering mechanism, and a processor. The steering mechanism steers the antenna in an azimuthal direction and an elevation direction. The processor is configured to (i) control the steering mechanism, (ii) receive data recorded by the antenna from a plurality of sources, (iii) time-stamp the data recorded by the antenna, and (iv) control the transmission of the time-stamped data to the correlator. The correlator is configured to receive the time-stamped recorded data from the first receiver and the second receiver, and calculate a distance between the first receiver and the second receiver based thereon.
Mems Nanotube Based Thermal Neutron Detector
(The Government of the United States of America, as represented by the Secretary of the Navy, Washington, DC (US), 2024-05-28) Hameed, Zishan; Gats, John; Meyyappan, Meyya; Han, Jin-Woo; Office of Research and Innovation
A MEMS nanotube based radiation sensor that is low cost, low power, compact, reliable and is applicable across many fields and a method for fabricating such a sensor are described. Each sensor may be connected to an array of similar but distinct sensors that leverage different material sand nanotube technology to detect radiation.
Vest Antenna Assembly
(The Government of the United States of America, as represented by the Secretary of the Navy, Washington, DC (US), 2002-03-12) Gainor, Thomas M.; Lebaric, Jovan E.; Research and Sponsored Programs Office (RSPO); Naval Postgraduate School (U.S.)
An antenna is formed on a vest by providing a pair of conducting regions on the outer surface. A non-conducting gap separates the conducting regions. A front conducting strip provides an electrical connection between the first and second electrically conducting portions. A feed conductor is connected to a conducting patch that is connected to one of the conducting regions.
