  • Publication number: 20190047621
    Abstract: A lane keeping assist method and system may include determining a driving state of a vehicle according to a state of a lane change in which an intention of a driver is reflected after a turn signal is applied, adjusting a criterion for driver override depending on an error between a driving path of the vehicle and a target path according to the driving state of the vehicle, comparing a steering torque of the driver with the adjusted criterion to determine activation or cancellation of the driver override, minimizing the driver's discomfort in the steering operation when the driver intentionally changes the lane.

  • Publication number: 20160206561
    Abstract: A complex coacervate delivery system is provided which encapsulates lipophilic nutrients such as, for example, fish oils high in omega-3 fatty acids. The complex coacervate delivery system protects the lipophilic nutrient from degradation, e.g., oxidation and hydrolysis, and also reduces or eliminates the unpleasant taste and odor of the lipophilic nutrient. The complex coacervate delivery system upon ingestion is operative to substantially release the lipophilic nutrient in the lower gastrointestinal tract in a pH-controlled manner. The complex coacervate delivery system may be included in a food or beverage product having a pH value within the range of about 1.5 to about 5.0.

  • Publication number: 20110212163
    Abstract: The present invention generally relates to systems and methods for releasing a compound from an article using an external trigger, for example, magnetic fields. One aspect of the invention is generally directed to an article containing a magnetically-susceptible material. Exposure of the magnetically-susceptible material to a magnetic field, such as an oscillating magnetic field, may cause the magnetically-susceptible material to increase in temperature. This increase in temperature may be used, in some embodiments, to cause the release of a drug or other releasable material from the article. For instance, the drug may be contained in a heat-sensitive material in thermal communication with the magnetically-susceptible material, or the drug may be contained within an enclosure that is isolated, at least in part, by a heat-sensitive material in thermal communication with the magnetically-susceptible material. Other aspects of the invention are directed to systems and methods of making or using such articles, e.

  • Publication number: 20080069857
    Abstract: The present invention provides compositions and methods for inhibiting adhesions. The methods involve administering solutions containing hydrogel precursors such as polysaccharide derivatives, e.g., derivatives of hyaluronic acid, cellulose, or dextran, to a subject at a site where adhesions may form, e.g., as a consequence of surgery, injury, or infection. The hydrogel precursors, e.g., polysaccharide derivatives, become crosslinked following their administration to form a hydrogel that maintains tissue separation. In certain embodiments of the invention one or both solutions contains particles, e.g., polymeric nanoparticles or microparticles, so that a composite hydrogel containing the particles is formed. The solution(s), particle(s), or both, may contain a biologically active agent such as an agent that contributes to inhibiting adhesions. The biologically active agent may be covalently attached to a hydrogel precursor.

  • Patent number: 6767637
    Abstract: A method for generating a plurality of drug-containing microcapsules employs one or more atomizers to form the microcapsules by the phenomenon of solvent exchange. A plurality of microdroplets of an aqueous solution is contacted with a plurality of microdroplets containing a polymer dissolved in a hydrophilic solvent under conditions whereby the polymer solution envelops the aqueous microdroplet. Exchange of solvent molecules between the aqueous core and its polymer-containing shell deposits the polymer as a membrane around the aqueous core. A preferred atomizer is a coaxial ultrasonic atomizer. Microcapsules can be generated in air as well as when submersed in a collection bath. Desired properties of the microcapsules, e.g., controlled release, can be achieved by providing protective excipients within the aqueous core, providing a hydrophilic polymer capable of undergoing a sol-to-gel transition within the aqueous core, optimizing selection of the polymer solvent, adjusting relative flow rates, and the like.
