  • Patent number: 10691282
    Abstract: Described is a high-assurance network gateway generator that generates and encodes network gateway code on a computer readable medium. In operation, the network gateway generator receives input artifacts, which are translated into corresponding formats as translated data. The translated data is distributed to an OS code generator, a glue code generator, and a communications code generator. The OS code generator then generates OS code based on the translated data. The communications code generator proceeds to generate deserialization and filtering code based on the translated data. Further, a glue code generator generates glue code based on the OS code and translated data. An executable network gateway code is then generated by combining the glue code, deserialization code, and filtering code. Finally, the executable network gateway code is then encoded on a computer readable medium.

  • Patent number: 10691972
    Abstract: Described is a system for discriminant localization of objects. During operation, the system causes one or more processors to perform an operation of identifying an object in an image using a multi-layer network. Features of the object are derived from the activations of two or more layers of the multi-layer network. The image is then classified to contain one or more object classes, and the desired object class is localized. A device can then be controlled based on localization of the object in the image. For example, a robotic arm can be controlled to reach for the object.

  • Patent number: 10691754
    Abstract: Described is a system for secure database searching. The system comprises a client-server architecture which allows a client to securely search a database of records possessed by a server. A database query is generated by the client and transmitted to the server. The database query is processed by the server using a privacy-preserving search protocol. An encrypted match result is produced by the server without decrypting the database query. The encrypted match result is sent to the client, and the client decrypts the encrypted match result to obtain a set of block identifiers representing blocks of records in the database that match the database query. The client obtains a block of encrypted records containing match results using only the set of block identifiers. The match results are decrypted by the client using a key obtained from the server. The unencrypted match results to the database query are then output.

  • Patent number: 10683400
    Abstract: This invention provides compositions and methods for reversible ionic crosslinking in polymers, providing tunability of polymer mechanical properties. Some variations provide a polymer composition comprising: a polymer containing a plurality of ionic species disposed along the chain backbone of the polymer, wherein the plurality of ionic species has an ionic charge polarity that is negative or positive; a redox reagent; and a reversible crosslinking agent capable of changing from a first oxidation state to a second oxidation state when in the presence of the redox reagent. The different oxidation states are associated with different coordination numbers between the reversible crosslinking agent and the ionic species contained in the polymer. This difference provides reversible ionic crosslinking. The polymer may be selected from polyurethanes (including segmented and non-segmented polyurethanes), polyacrylates, or polyamides, for example.

  • Patent number: 10679355
    Abstract: Described is a system for detecting moving objects. During operation, the system obtains ego-motion velocity data of a moving platform and generates a predicted image of a scene proximate the moving platform by projecting three-dimensional (3D) data into an image plane based on pixel values of the scene. A contrast image is generated based on a difference between the predicted image and an actual image taken at a next step in time. Next, an actionable prediction map is then generated based on the contrast mage. Finally, one or more moving objects may be detected based on the actionable prediction map.

  • Patent number: 10676083
    Abstract: Described is a system for prediction and active compensation of occupant motor response in a vehicle accident. The system uses a spinal reflex model to generate a stimulus based on an accident scenario of an occupant in a vehicle, the stimulus being a set of proprioceptive signals induced by the accident scenario. A neuromuscular model then determines activation and contraction dynamics based on the stimulus. The activation and contraction dynamics represent muscle contraction forces spanning a skeletal system of the occupant. A musculoskeletal model then generates a predicted motor response of the occupant based on the activation and contraction dynamics. The predicted motor response can be used for a variety of purposes, such as initiating active compensation in a vehicle or modifying airline cabin design parameters to decrease the likelihood of injury to the occupant.

  • Patent number: 10673074
    Abstract: The present invention provides a battery electrode comprising an active battery material enclosed in the pores of a conductive nanoporous scaffold. The pores in the scaffold constrain the dimensions for the active battery material and inhibit sintering, which results in better cycling stability, longer battery lifetime, and greater power through less agglomeration. Additionally, the scaffold forms electrically conducting pathways to the active battery nanoparticles that are dispersed. In some variations, a battery electrode of the invention includes an electrically conductive scaffold material with pores having at least one length dimension selected from about 0.5 nm to about 100 nm, and an oxide material contained within the pores, wherein the oxide material is electrochemically active.

  • Patent number: 10666248
    Abstract: A circuit biases an input transistor by using a voltage on a reference transistor having open gate connection and operating at the same current density as the input transistor to null current leakage at the gate of the input transistor. The input transistor is biased based on the voltage on the zero-gate-current reference transistor. The bias condition for the input transistor to operate at a zero gate current is determined by leaving the gate terminal of the reference transistor open-circuited, thus zero gate current, forcing a desired current through the reference transistor, and measuring a drain-source voltage of the reference transistor. When the input terminal of the input transistor has an ancillary circuitry that may contribute gate leakage current, the same ancillary circuitry can be coupled to the gate of the reference transistor.
