  • Patent number: 11486223
    Abstract: Embodiments of the disclosure include swellable smart gel sealants and methods of using smart gel sealants. In certain embodiments, the smart gel sealants reversibly swell when exposed to a certain trigger, such as temperature or pH. In specific embodiments, the smart gel is disposed within voids in a well and triggered to swell in order to seal the voids. One application of the smart gel sealant is to seal the casing of a well against the leakage of gas, such as H2S.

  • Patent number: 11176718
    Abstract: The disclosed examples relate to arranging graph data for display on a display device. One example provides, on a computing device, a method comprising determining one or more connected groups of nodes in directed acyclic graph data, for each connected group of nodes, determining a reachability from each node with no inputs to each of one or more nodes with no outputs to determine a plurality of initial node/terminal node pairs, and for each initial node/terminal node pair, determining a path from the initial node to the terminal node. The method further comprises initializing a grid based upon the determined paths, placing each node at a corresponding initial grid location, and placing edges between nodes based upon the determined paths to form an initial grid representation, modifying the initial grid representation via a cost function to form a modified grid representation, and outputting the modified grid representation for display.

  • Patent number: 11144535
    Abstract: An on-board recording system for a vehicle is disclosed. The on-board recording system is configured to monitor data for errors. The on-board recording system includes one or more processors and a memory coupled to the one or more processors. The memory stores data comprising a database and program code that, when executed by the processors, causes the on-board recording system to receive as input a data sequence including a plurality of frames. The frames are received and recorded by the on-board recorder at a corresponding assigned time offset and include a corresponding assigned message. The on-board recording system is further caused to determine a missing assigned message that has not been received at the corresponding assigned time offset. In response to determining the missing assigned message, the on-board recording system calculates a total length of time based on a number of missing assigned messages stored in the memory.

  • Patent number: 11084794
    Abstract: The present disclosure provides improved methods for controlled cyclization of peptoid dimers to form N,N?-2,5-diketopiperazines (N,N?-2,5-DKPs) with significant selectivity. In at least some examples, selectivity is based on a serendipitous conglomeration of slow exchange of amide rotamers, steric repulsion from the degree of ?-substitution, and the geometric bulk of an amine nucleophile. By varying reaction conditions, the selectivity of the reaction and formation of a particular N,N?-2,5-DKP can be switched. The cyclization works in the presence of a variety of protection groups and diverse functionalities. The teachings herein provide techniques for synthesizing N,N?-2,5-DKPs that can be readily docked with drug candidates for shuttling across the blood brain barrier. This method provides a facile way to produce substituted DKPs containing groups ready for post-modification to include docking drug candidates.

  • Patent number: 10760597
    Abstract: A material-mapped actuator useful as, or as part of, a soft robot along with automated methods of design and manufacture. The actuator exhibits mechanical properties that spatially vary along a coordinate system of the actuator. The actuator body has an initial shape with a corresponding initial map of mechanical attributes consisting of locally-varying stiffness at each point in a volume of the actuator body. The actuator is configured to change to a different shape or distribution of mechanical properties upon being activated by an actuation medium. The map of mechanical attributes influences and determines the new shape or distribution. The material-mapped actuator can incorporate a spatially-varying distribution of mechanical properties that dictates multiple desired shapes as the actuation medium is applied, including an actuation sequence in which the actuator transitions from a first shape to a desired intermediate shape(s), and from the intermediate shape to a desired final shape.

  • Patent number: 7834319
    Abstract: An improved nanophosphor composite comprises surface modified nanophosphor particles in a solid matrix. The nanophosphor particle surface is modified with an organic ligand, or by covalently bonding a polymeric or polymeric precursor material. The surface modified nanophosphor particle is essentially charge neutral, thereby preventing agglomeration of the nanophosphor particles during formation of the composite material. The improved nanophosphor composite may be used in any conventional scintillator application, including in a radiation detector.

  • Publication number: 20050102283
    Abstract: An interactive, graphical depiction of a form (e.g., a tax, banking, insurance or other form) is presented through a computer network. A request is received through the network for information relating to a location on the form selected by a user, where the selection is made through interaction with the graphical depiction of the form. Information is delivered to the user through the network in response to the request. The delivered information may include one or more of the following relating to the selected form location: planning information, consulting materials, research and compliance information. An interactive depiction of a map or series of maps also may be presented through the network. The user may interact with the map to obtain jurisdiction-specific information on a topic that relates to the subject matter of the graphical, interactive form. The jurisdiction-specific information also may be delivered to the user through the network.
