  • Patent number: 11443834
    Abstract: The invention relates to an automatic conformation analysis method for quasi-drug organic molecules. The method includes: extracting a group of fragments from an input molecule, wherein there are primarily three types of fragments: a flexible bond fragment, a ring isomerism fragment and a conformation isomerism fragment; carrying out knowledge-based conformation recommendation; carrying out conformation recommendation based on force field scanning; verifying, by QM, the generated conformations, wherein if the verification succeeds, it indicates that the recommended conformations are valid; or otherwise, the force field is corrected; collecting conformation lists of the fragments; and combining and optimizing conformation parameters of the fragments through a genetic algorithm, and finding out a set of optimal conformations. The invention integrates the advantages of a knowledge-based method and the advantages of a computation method, so that accurate conformation recommendations can be acquired.

  • Patent number: 11440315
    Abstract: There is provided an ink jet recording apparatus including an ink jet head and a drive circuit. The ink jet head forms an image on a recording medium in response to a drive signal applied to multiple piezoelectric elements. The drive signal causes multiple pressure chambers corresponding to the multiple piezoelectric elements to expand or to contract in volume and causes ink in the multiple pressure chambers to be discharged from multiple nozzles. The drive circuit generates a drive signal for discharging multiple liquid droplets to one pixel for combining the multiple liquid droplets together and applies the drive signal to each of the multiple piezoelectric elements of the ink jet head. The drive signal includes multiple discharge pulses which make velocities of tips of respective liquid columns substantially same after a predetermined time from starting of ink discharge from the nozzles.

  • Patent number: 11413891
    Abstract: Embodiments provide for a conveying system to move multiple articles from one location to another. The conveying system may use a transport device to grasp each article from an initial location, rotate the articles away from the initial locations, move the articles linearly, and rotate the articles to destination locations. Rather than moving each article one-by-one, in the embodiments described herein, the conveying system can move multiple articles simultaneously to various locations where each location may contain a different process to perform on the article. Moving multiple articles simultaneously shortens the time required to process the articles.

  • Patent number: 11391567
    Abstract: Measurement approaches and data analysis methods are disclosed for combining 3D topographic data with spatially-registered gas concentration data to increase the efficiency of gas monitoring and leak detection tasks. Here, the metric for efficiency is defined as reducing the measurement time required to achieve the detection, or non-detection, of a gas leak with a desired confidence level. Methods are presented for localizing and quantifying detected gas leaks. Particular attention is paid to the combination of 3D spatial data with path-integrated gas concentration measurements acquired using remote gas sensing technologies, as this data can be used to determine the path-averaged gas concentration between the sensor and points in the measurement scene.
