  • Publication number: 20150141817
    Abstract: Various methods of performing ultrasound contrast assisted therapy are provided. One such method includes delivering a plurality of microbubble-based ultrasound contrast agents to a target area and disrupting the microbubble-based ultrasound contrast agents by delivering tone bursts of ultrasound to the target area. The oscillation of the microbubble-based ultrasound contrast agents can be achieved by delivering ultrasound tone bursts of greater than 5 acoustic cycles with a pulse repetition frequency of between 0.01 and 20 Hz, with pressure greater than 0.3 MPa.

  • Patent number: 9008836
    Abstract: A method and system to optimize the parameters of a robot used in an assembly process. The assembly process is categorized based on its nature which may be cylindrical, radial and multi-stage insertion. The search pattern and search parameters are specified. The parameters are optimized and the optimized parameter set are verified and when a predetermined criteria such as assembly cycle time set and/or success rate is met the optimization process stops. When the optimization stops the verified parameters are used to cause the robot to perform the categorized assembly process. If the parameters do not meet the predetermined criteria, another round of optimization using the same or other parameters can be performed.

  • Patent number: 8940277
    Abstract: This invention addresses the clinical problem of how to optimize biological cell based therapies, such as stem cell therapy. Currently, cell therapies administered by intravenous, intra-arterial, and/or direct tissue injection are limited by the lack of clinically available imaging methods to detect the in vivo fate of the administered cells. There are many efforts underway to develop imaging strategies for stem cells in vivo, including radionuclide and MRI-based approaches. However, these approaches are limited by potential safety issues (e.g. radioactive exposure of stem cells, toxicity of iron particles used for MRI) and difficulty in serial tracking due to complex instrumentation and/or the requirement for repetitive radiation exposure.

  • Publication number: 20140342389
    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: 20140156073
    Abstract: A teleoperated robot system has a watchdog to determine if the rate of data transmission from a computing device such as a robot controller located in the station used by the operator of the teleoperated robot to the remotely located industrial robot has fallen below a minimum data rate or the time for transmission of data has exceeded a maximum time. Upon the occurrence of either or both of the foregoing, one or more types of corrective action are undertaken to bring the teleoperated robot and the processes performed by the robot.

  • Publication number: 20130204166
    Abstract: The invention pertains to a lipid-based microbubble stably binding a plurality of nucleic acids, and a method of delivering the microbubble and nucleic acids to a specific target site using ultrasound. The delivered nucleic acids create transgenic cells (i.e., for example, a transgenic tumor cell), wherein the transgenic cell expresses the proteins encoded by the delivered nucleic acids. This technology provides a significant improvement for microbubble-drug delivery platforms as known microbubble do not efficiently bind nucleic acids. The improvements described herein include but are not limited to identifying proper lipid proportionality ratios and/or cationic surfactant layers that provide an optimum mechanical index compatible with ultrasonics. Microbubble perfusion and/or nucleic acid delivery may be performed by a combination of imaging and ultrasound/microbubble targeted delivery to simultaneously perform low power two-dimensional imaging and high power microbubble destruction.

  • Publication number: 20130147944
    Abstract: A vision-guided alignment system to align a plurality of components includes a robotic gripper configured to move one component relative to another component and a camera coupled to a processor that generates an image of the components. A simulated robotic work cell generated by the processor calculates initial calibration positions that define the movement of the robotic gripper such that position errors between the actual position of the robotic gripper and the calibration positions are compensated by a camera space manipulation based control algorithm executed by the processor to control the robotic gripper to move one component into alignment with another component based on the image of the components.

  • Patent number: 8460269
    Abstract: The disclosed technology describes compositions and methods useful for providing cell based therapy. For example, one embodiment of cell based therapy involves the regeneration of injured tissue and/or promoting wound healing. Certain embodiments provide improved therapeutic compositions using microbubbles by delivering biological progenitor cells to the injured tissues. The administration of the microbubbles is directed by acoustic radiation forces that interact with embodiments of microbubbles comprising an acoustically active gas. As such, a high efficiency of progenitor cell delivery to injured tissue is realized. One advantage of this technique over targeted delivery of pharmaceutical compounds, is that the delivered progenitors cells may be derived from the patient (i.e., personalized therapy), thereby avoiding side effects, allergic reactions, and overall problems associated with refractive drug responses.
