Abstract: Described is a system for adaptable neurostimulation intervention. The system monitors a set of neurophysiological signals in real-time and updates a physiological and behavioral model. The set of neurophysiological signals are classified in real-time based on the physiological and behavioral model. A neurostimulation intervention schedule is generated based on the classified set of neurophysiological signals. The system activates electrodes via a neurostimulation intervention system to cause a timed neurostimulation intervention to be administered based on the neurostimulation intervention schedule. The neurostimulation intervention schedule and timed neurostimulation intervention are refined based on new sets of neurophysiological signals.

Abstract: Described is neuromorphic system for authorized user detection. The system includes a client device comprising a plurality of sensor types providing streaming sensor data and one or more processors. The one or more processors include an input processing component and an output processing component. A neuromorphic electronic component is embedded in or on the client device for continuously monitoring the streaming sensor data and generating out-spikes based on the streaming sensor data. Further, the output processing component classifies the streaming sensor data based on the out-spikes to detect an anomalous signal and classify the anomalous signal.

Abstract: Described is a system for co-adaptation of robot control to human biomechanics. During operation, the system receives joint angle and joint velocity of a human and co-robot and generates estimated internal states of the human. A task space motion plan is then generated for the co-robot based on a specified cooperative task and estimated internal states and joint angle and joint velocity of the human. Joint torque commands are then generated based on the task space motion plan and joint angle and joint velocity of the human and co-robot. Motion of the co-robot is then controlled, such as causing the co-robot to actuate one or more actuators to move based on the joint torque commands.

Abstract: The invention provides a highly durable surface coating intended to inhibit the formation of ice at sub-0° C. temperatures as well as reduce the accumulation of dirt and insect debris to a vehicle surface upon impact. A continuous, durable matrix surrounds both low-surface-energy (low-adhesion) material inclusions as well as hygroscopic material inclusions. Some variations provide a low-friction, low-adhesion material comprising: a durable continuous matrix; a plurality of first inclusions, dispersed within the matrix, each comprising a low-surface-energy polymer; and a plurality of second inclusions, dispersed within the matrix, each comprising a hygroscopic material. The matrix and the first and second inclusions form a lubricating surface layer in the presence of humidity. Other variations employ a durable continuous matrix and a plurality of inclusions, dispersed within the matrix, each comprising a low-surface-energy polymer surrounding a hygroscopic material. Coating precursors and methods of forming final coatings are also described.

Abstract: A sacrificial substrate for use in stereolithography, having a first surface configured to be attached to a build platform, and a second surface of the sacrificial substrate configured to be attached to a photopolymer part. The sacrificial substrate physically separates the build platform and the photopolymer part, and serves as the deposition surface for the photopolymer part in place of the build platform. The sacrificial substrate may be separated from the build platform and then separated from the photopolymer part via pyrolysis, oxidation, or etching to thereby yield the free photopolymer part without subjecting the part to excess physical force or damage.

Abstract: Described is a system for anonymous job allocation and majority voting in a cloud computing environment. The system broadcasts a job to physical nodes, each of the physical nodes having a control operations plane (COP) node and one or more service nodes associated with the COP node. A set of redundant job assignments is distributed to individual COP nodes pursuant to a private job assignment schedule, such that each individual COP node is only aware of its own assignment and corresponding job. The service nodes execute the job assigned to the COP nodes such that the service nodes each complete a task associated with the job and forward an individual result to their associated COP node. A privacy-preserving result checking protocol is performed amongst the COP nodes such that secret shares of a majority result are obtained and the majority result is provided to a client.

Abstract: A metal microparticle coated with metal hydride nanoparticles is disclosed. Some variations provide a material comprising a plurality of microparticles (1 micron to 1 millimeter) containing a metal or metal alloy and coated with a plurality of nanoparticles (less than 1 micron) containing a metal hydride or metal alloy hydride. The invention eliminates non-uniform distribution of sintering aids by attaching them directly to the surface of the microparticles. No method is previously known to exist which can assemble nanoparticle metal hydrides onto the surface of a metal microparticle. Some variations provide a solid article comprising a material with a metal or metal alloy microparticles coated with metal hydride or metal alloy hydride nanoparticles, wherein the nanoparticles form continuous or periodic inclusions at or near grain boundaries within the microparticles.

Abstract: Described is a learning system for multi-agent applications. In operation, the system initializes a plurality of learning agents. The learning agents include both tactical agents and strategic agents. The strategic agents take an observation from an environment and select one or more of the tactical agents to produce an action that is used to control a platform's actuators or simulated movements in the environment to complete a task. Alternatively, the tactical agents produce the action corresponding to a learned low-level behavior to control the platform's actuators or simulated movements in the environment to complete the task.
