  • Patent number: 11318225
    Abstract: Thin parylene C membranes having smooth front sides and ultrathin regions (e.g., 0.01 ?m to 5 ?m thick) interspersed with thicker regions are disclosed. The back sides of the membranes can be rough compared with the smooth front sides. The membranes can be used in vitro to grow monolayers of cells in a laboratory or in vivo as surgically implantable growth layers, such as to replace the Bruch's membrane in the eye. The thin regions of parylene are semipermeable to allow for proteins in serum to pass through, and the thick regions give mechanical support for handling by a surgeon. The smooth front side allows for monolayer cell growth, and the rough back side helps prevents cells from attaching there.

  • Patent number: 11313696
    Abstract: A vehicle is described, and includes an on-board controller, an extra-vehicle communication system, a GPS sensor, a spatial monitoring system, and a navigation system that employs an on-vehicle navigation map. Operation includes capturing a 3D sensor representation of a field of view and an associated GPS location, executing a feature extraction routine, executing a semantic segmentation of the extracted features, executing a simultaneous location and mapping (SLAM) of the extracted features, executing a context extraction from the simultaneous location and mapping of the extracted features, and updating the on-vehicle navigation map based thereon. A parsimonious map representation is generated based upon the updated on-vehicle navigation map, and is communicated to a second, off-board controller. The second controller executes a sparse map stitching to update a base navigation map based upon the parsimonious map representation. The on-vehicle navigation map is updated based upon the off-board navigation map.

  • Patent number: 11308400
    Abstract: An optimally stopped heuristic optimizer includes a processor. The processor heuristically generates a sequence of proposed solutions for solving a discrete optimization problem associated with an objective function, and for each additional proposed solution of the sequence, derives an estimate of a quality distribution that is based on the sequence including the additional proposed solution. The quality distribution assigns a probability to each of the proposed solutions according to quality of the proposed solution. The processor further, responsive to a most recent additional proposed solution of the sequence having quality better than a quality threshold that is defined by the estimate corresponding to the sequence including the most recent additional proposed solution, commands a stop such that further proposed solutions to the discrete optimization problem are no longer generated, and identifies and outputs a selected one of the sequence having best quality.

  • Patent number: 11303281
    Abstract: An SFQ circuit system includes at least one SFQ block having a plurality of SFQ logic gates. Characteristically, at least a portion of the SFQ logic gates are arranged in series. The SFQ circuit system includes a timing system configured to provide a first set of inputs and collect a first set of outputs of the at least one SFQ block at a rate defined by a slow clock frequency while the SFQ logic gates are clocked at a fast clock frequency. Advantageously, the rate is sufficiently slow to allow the first set of inputs to propagate through all levels of the SFQ logic gates to produce the first set of outputs of the at least one SFQ block without colliding with a second set of inputs to the at least one SFQ block.

  • Patent number: 11278226
    Abstract: A fully-implantable brain-computer interface cyber-physical system capable of acquiring and analyzing electrocorticogram (“ECoG”) signals, recorded directly from the subdural space of the brain, to enable direct brain control of a prosthetic (e.g., a robotic gait exoskeleton or a functional electrical stimulation (“FES”) system) is disclosed. The present system comprises a plurality of electrodes, for acquiring the ECoG signals, and a digital signal processor (“DSP”) for deriving a plurality of real-time commands from the ECoG signals. These real-time commands may then be wirelessly transmitted to the prosthetic for execution. Further, to avoid wireless data transmission of the ECoG signals from the plurality of electrodes to the DSP, which would expose the brain, skull, and scalp tissue to potentially harmful radio frequencies, a subcutaneous tunneling cable operatively couples the plurality of electrodes and the DSP.

  • Publication number: 20220064672
    Abstract: Oncolytic viruses offer an in situ vaccination approach to activate tumor-specific T cell responses. However, the upregulation of PD-L1 expression on tumor cells and immune cells leads to tumor resistance to oncolytic immunotherapy. Herein, we generate an engineered oncolytic virus that coexpresses a PD-L1 inhibitor and GM-CSF. This oncolytic virus is capable of secreting the PD-L1 inhibitor that systemically binds and inhibits PD-L1 on tumor cells and immune cells. The intratumoral injection with the oncolytic virus overcomes PD-L1-mediated immunosuppression during both the priming and effector phases, provokes systemic T cell responses against dominant and subdominant neoantigen epitopes derived from mutations, and leads to an effective rejection of both virus-injected and distant tumors.

  • Patent number: 11256982
    Abstract: A learning computer system may include a data processing system and a hardware processor and may estimate parameters and states of a stochastic or uncertain system. The system may receive data from a user or other source. Parameters and states of the stochastic or uncertain system are estimated using the received data, numerical perturbations, and previous parameters and states of the stochastic or uncertain system. It is determined whether the generated numerical perturbations satisfy a condition. If the numerical perturbations satisfy the condition, the numerical perturbations are injected into the estimated parameters or states, the received data, the processed data, the masked or filtered data, or the processing units.

  • Patent number: 11250601
    Abstract: A Convolutional Neural Network (CNN) assisted dielectric imaging method is provided. The method used CNN to incorporate the abundant image information from Magnetic Resonance (MR) images into the inverse scattering model-based microwave imaging process and generate high-fidelity dielectric images. A CNN is designed and trained to learn the complex mapping function from MR T1 images to dielectric images. Once trained, the new patients' MR T1 images are fed into the CNN to generate predicted dielectric images, which are used as the starting image for the microwave inverse scattering imaging. The CNN-predicted dielectric image significantly reduces the non-linearity and ill-posedness of the inverse scattering problem. The application of the proposed method to recover human brain dielectric images at 4 mm and 2 mm resolution with single-frequency and multi-frequency microwave measurements is provided.
