  • Patent number: 11370124
    Abstract: A system and method for predicting the location at which a feature that is being tracked during a robotic assembly operation will be located within one or more images captured by a vision device. A vision device can be mounted to a robot such that the location of the vision device as the robot moves can be known or determined. In the event of an interruption of the tracking of the feature by the vision device as the corresponding workpiece is moving, the location of the feature relative to a vision device can be predicted, such as, via use of current or past historical movement information for the feature and/or the associated workpiece. Using the predicted location of the feature and the known location of the vision device, the location at which the feature will be located in an image(s) captured by the vision device can be predicted.

  • Publication number: 20220192180
    Abstract: A thawing solution has 0.1-50 g of a biomimetic material for controlling ice, 0-1.0 mol L?1 of a water-soluble sugar, and balance of a buffer solution. The biomimetic material for controlling ice is a material for controlling ice having an ice-philic group and a hydrophilic group. The hydrophilic group is a functional group that can form a non-covalent interaction with water molecules, and the ice-philic group is a functional group that can form a non-covalent interaction with ice. Using the thawing solution and the thawing reagent prepared from the biomimetic material for controlling ice, which material has ice-philic and hydrophilic properties, the growth and recrystallization of ice crystals can be effectively controlled, and damage to cells or tissue caused by uncontrolled growth of the ice crystals during recovery can be significantly ameliorated.

  • Patent number: 11366450
    Abstract: Apparatus and method is disclosed for determining position of a robot relative to objects in a workspace which includes the use of a camera, scanner, or other suitable device in conjunction with object recognition. The camera, etc is used to receive information from which a point cloud can be developed about the scene that is viewed by the camera. The point cloud will be appreciated to be in a camera centric frame of reference. Information about a known datum is used and compared to the point cloud through object recognition. For example, a link from a robot could be the identified datum so that, when recognized, the coordinates of the point cloud can be converted to a robot centric frame of reference since the position of the datum would be known relative to the robot.

  • Publication number: 20220167610
    Abstract: A cryopreservation solution contains 0.01-50.0 g of bionic ice control materials, 5.0-30 mL of polyols, 1-30 g of water-soluble sugar, and 0-30 mL of serum, and a buffer in every 100 mL of the cryopreservation solution. It does not contain DMSO. When being used for the cryopreservation of mouse oocytes and embryos, the solution may achieve the same or an even higher cell and tissue survival rate and functional expression stability as or than a commercial cryopreservation solution (containing 15% DMSO), and has high preservation efficiency. The cryopreservation solution without DMSO or serum reduces parasitic biological contaminants in the commercial cryopreservation solution containing serum currently used in clinical practice.

  • Publication number: 20210339387
    Abstract: A robotic system is provided for assembling parts together. In the assembly process, both parts are moving separately with one part moving on an assembly base and another part moving on a moveable arm of a robot base. Motion data is measured by an inertial measurement (IMU) sensor. Movement of the robot base or moveable arm is then compensated based on the measured motion to align the first and second parts with each other and assemble the parts together.

    Abstract: A robotic assembly operation is provided for assembling a second part to a first part. During setup of the assembly operation, control parameters and a control scheme are set and changed by simulating the operation and testing whether performance requirements are met. A dry run may be performed thereafter, and test data may be collected after running the simulation to determine if the performance requirements are satisfied during the dry run. During production, production data may also be collected and control parameters may be tuned when changes occur during production in order to maintain stable assembly.

  • Patent number: 11154584
    Abstract: A protein transduction method for efficiently delivery of exogenous proteins into mammalian cells is invented, which has the capability of targeting different cellular compartments and protection from degradation of the delivered proteins from cellular proteases. A composition for treat proteins has cation reagents, lipids and enhancers in a carrier. The method can be used in a number of ways including: production of large quantities of properly folded, post-translationally modified proteins using mammalian cell machinery a in-cell fluorescence spectroscopy and imaging using small molecule fluorophores and a in-cell NMR spectroscopy using living mammalian cells. The method permits cell biology at atomic resolution that is physiologically and pathological relevant and permits protein therapy to treat human diseases. The method can also be used to deliver exogenous protein inside mammalian cells, wherein the exogenous proteins follow a similar secretion pathway as that of the endogenous protein.

  • Publication number: 20210323158
    Abstract: A system and method for automatic recovery from a failure in a robotic assembly operation using multiple sensor input. Moreover, following detection of an error in an assembly operation from data provided by a first sensor, a recovery plan can be executed, and, if successful, a reattempt at the failed assembly operation can commence. The assembly stage during which the error occurred can be detected by a second sensor that is different from the first sensor. Identification of the assembly stage can assist with determining the recovery plan, as well as identifying the assembly operation that is to be reattempted. The failure can be detected by comparing information obtained from a sensor, such as, for example, a force signature, with corresponding historical information, including historical information obtained at the identified assembly stage for prior workpieces.

  • Publication number: 20210323164
    Abstract: A system and method that automatically resolves conflicts among sensor information in a sensor fusion robot system. Such methods can accommodate converging ambiguous and divergent sensor information in a manner that can allow continued, and relatively accurate, robotic operations. The processes can include handling sensor conflict via sensor prioritization, including, but not limited, prioritization based on the particular stage or segment of the assembly operation when the conflict occurs, overriding sensor data that exceeds a threshold value, and/or prioritization based on evaluations of recent sensor performance, predictions, system configuration, and/or historical information. The processes can include responding to sensor conflicts through comparisons of the accuracy of workpiece location predictions from different sensors during different assembly stages in connection with arriving at a determination of which sensor(s) is providing accurate and reliable predictions.
