  • Patent number: 11757669
    Abstract: Generating an agenda for a meeting includes creating a content repository that includes content corresponding to feedback from previous targeted meetings and/or information corresponding to ongoing discussions between potential attendees of the meeting, automatically creating a prioritized list of discussion topics, and at least one expert providing gestures to a computer screen to create an assessment for the discussion topics, display additional data for the prioritized list of the discussion topics, and/or transfer one or more of the discussion topics of the prioritized list of the discussion topics to either a list of dropped discussion topics or to an ordered list of selected discussion topics. An agenda is automatically generated based on the ordered list of selected discussion topics and on weights assigned to the at least one expert according to relative expertise. An order of agenda items is based in part on the weights.

  • Patent number: 11635527
    Abstract: It is provided a joint receiver and receiving method for navigation signals located at adjacent frequencies. The joint receiving method includes: receiving a first navigation signal and a second navigation signal which are located at adjacent frequencies (S1); and calculating a frequency estimation of a virtual wideband navigation signal constructed based on the first navigation signal and the second navigation signal (S2), wherein the virtual wideband navigation signal is an asymmetric BOC-like navigation signal having a virtual carrier and a virtual sub-carrier. With the joint receiver and joint receiving method, not only power gain but also bandwidth gain can be obtained, and the ranging precision can be significantly improved.

  • Patent number: 11204296
    Abstract: The present invention provides a horizontal instrument, a supporting device and a method for adjusting the bearing surface of the supporting device to be horizontal. The horizontal instrument in the present invention is used for maintaining a bearing surface parallel to a horizontal plane, wherein the horizontal instrument comprises a slide-swing assembly, and a monitoring assembly, when the monitoring assembly detects that the bearing surface is not parallel to the horizontal plane, the controller instructs the driving unit to drive the slider to slide, which leads the lower end of the swinging rod to slide, and then drives the swinging rod to swing, thereby, the upper end of the swinging rod drives the bearing surface to rotate for an angle so that the bearing surface is maintained parallel to the horizontal plane.
