  • Patent number: 11557216
    Abstract: An anatomical feature simulation unit is a physical device designed to help simulate an anatomical feature (e.g., a wound) on an object (e.g., a human being or human surrogate such as a medical manikin) for instructing a trainee to learn or practice treatment skills. For the trainee, the simulation looks like a real body part when viewed using an Augmented Reality (AR) system. Responsive to a change in the anatomic state of the object (e.g., bending a knee or raising of an arm) not only the spatial location and orientation of the anatomical feature stays locked on the object in the AR system, but the characteristics of the anatomical feature change based on the physiologic logic of changing said anatomical state (e.g., greater or less blood flow, opening or closing of a wound).

  • Patent number: 11547117
    Abstract: Disclosed herein is a nano-coating platform that is designed to ‘capture’ and ‘kill’ (i.e. inactivate) virus species to prevent surface to surface contamination/transmission and thereby the spread of novel viruses. The platform is comprised of alternating layers of charged polymers (producing a multi-layer coating). The cationic layer may be grafted with oligomeric species, chosen to bind strongly to unique/specific virus surface features, thereby mediating capture of the virus (with the choice of oligomeric species allowing generalization to a given virus). Natural light (excitation) to UV (local emission) up-converting nanoparticles are seeded into the anionic layer and mediate the inactivation (‘killing’) of the bound virus species.

  • Patent number: 11551344
    Abstract: A smart, human-centered technique that uses artificial intelligence and mixed reality to accelerate essential tasks of the inspectors such as defect measurement, condition assessment and data processing. For example, a bridge inspector can analyze some remote cracks located on a concrete pier, estimate their dimensional properties and perform condition assessment in real-time. The inspector can intervene in any step of the analysis/assessment and correct the operations of the artificial intelligence. Thereby, the inspector and the artificial intelligence will collaborate/communicate for improved visual inspection. This collective intelligence framework can be integrated in a mixed reality supported see-through headset or a hand-held device with the availability of sufficient hardware and sensors. Consequently, the methods reduce the inspection time and associated labor costs while ensuring reliable and objective infrastructure evaluation.

  • Patent number: 11538362
    Abstract: A tactile display device including a nodule having variable stiffness under a surface to provide a near-real feeling of palpation for a physician. The device utilizes granular jamming technology using pneumatic actuation to control a nodule that maintains its shape while allowing the modulation in stiffness. The nodule includes two hemispheres, a contact portion and an actuation portion, forming a sphere. The contact portion and the actuation portion include different thicknesses and/or materials, while the dimensions of the dimensions of the nodule are maintained. As such, a physician can utilize the device to identify the difference between a normal lump and an affected lump even if the shape of each lump appears to be the same. With the tactile display device, due to the different levels of stiffness, a physician can detect the severity of the lump.

  • Patent number: 11535261
    Abstract: Virtual humans exhibit behaviors associated with inputs and outputs of an autonomous control system for medical monitoring of patients. To foster the awareness and trust, the virtual humans exhibit situational awareness via apparent (e.g., rendered) behaviors based on inputs such as physiological vital signs. The virtual humans also exhibit situational control via apparent behaviors associated with outputs such as direct control of devices, functions of control, actions based on high-level goals, and the optional use of virtual versions of conventional physical controls. A dynamic virtual human who continually exhibits awareness of the system state and relevant contextual circumstances, along with the ability to directly control the system, is used to reduce negative feelings associated with the system such as uncertainty, concern, stress, or anxiety on the part of real human patients.

  • Patent number: 11538989
    Abstract: An in-memory computing architecture is disclosed that can evaluate the transitive closure of graphs using the natural parallel flow of information in 3-D nanoscale crossbars. The architecture can be implemented using 3-D crossbar architectures with as few as two layers of 1-diode 1-resistor (1D1R) interconnects. The architecture avoids memory-processor bottlenecks and can hence scale to large graphs. The approach leads to a runtime complexity of O(n2) using O(n2) memristor devices. This compares favorably to conventional algorithms with a time complexity of O((n3)/p+(n2) log p) on p processors. The approach takes advantage of the dynamics of 3-D crossbars not available on 2-D crossbars.

  • Patent number: 11517531
    Abstract: Cerium oxide nanoparticles (CNPs) have been proven to exhibit antioxidant properties attributed to its surface oxidation states (Ce4+ to Ce3+ and vice versa) mediated at the oxygen vacancies on the surface of CNPs. Different anions in precursor cerium salts were used to prepare CNPs resulting in disclosed CNPs with varying physicochemical properties such as dispersion stability, hydrodynamic size, and the signature surface chemistry. The antioxidant catalytic activity and oxidation potentials of different CNPs have been significantly altered with the change of anions in the precursor salts. For one, CNPs prepared using precursor salts containing NO3? and Cl? ions exhibited increased antioxidant activity than previously thought possible. The change in oxidation potentials of CNPs with the change in concentration of the nitrate and chloride ions indicates the disclosed CNP's have different surface chemistry and antioxidant properties. These compositions and methods of their synthesis are disclosed.

  • Patent number: 11522195
    Abstract: Enabling the use of lithium metal as an anode electrode is a key for developing next generation energy storage device beyond current lithium ion battery technology. However, there are major obstacles that need to be overcome before it can be used in commercial applications; specifically, dendrite formation can short the cell, and electrolyte decomposition contributes to decreased battery lifetimes. Each obstacle can be overcome by coating a lithium metal anode with a liquid metal buffer that enables uniform deposition of lithium ions thereon, preventing dendritic growth and forming a stable solid electrolyte interface to separate the lithium metal anode from the electrolyte within a battery cell. The liquid metal buffer becomes a semi-liquid buffer when contributing to forming a solid electrolyte interface, and can regain its liquid state when the lithium ions flow to the cathode of the battery cell.

  • Patent number: 11514579
    Abstract: An improved method of performing object segmentation and classification that reduces the memory required to perform these tasks, while increasing predictive accuracy. The improved method utilizes a capsule network with dynamic routing. Capsule networks allow for the preservation of information about the input by replacing max-pooling layers with convolutional strides and dynamic routing, allowing for the reconstruction of an input image from output capsule vectors. The present invention expands the use of capsule networks to the task of object segmentation and medical image-based cancer diagnosis for the first time in the literature; extends the idea of convolutional capsules with locally-connected routing and propose the concept of deconvolutional capsules; extends the masked reconstruction to reconstruct the positive input class; and proposes a capsule-based pooling operation for diagnosis.

  • Patent number: 11512099
    Abstract: Covalent organic frameworks (COFs) usually crystallize as insoluble powders and their processing for suitable devices has been thought to be limited. Here, it is demonstrated that COFs can be mechanically pressed into shaped objects having anisotropic ordering with preferred orientation between the hk0 and 00/ crystallographic planes. Pellets prepared from bulk COF powders impregnated with LiClO4 displayed room temperature conductivity up to 0.26 mS cm?1 and stability up to 10.0 V (vs. Li+/Li0). This outcome portends use of COFs as solid-state electrolytes in batteries.
