  • Patent number: 11809203
    Abstract: Provided is a vertical take-off/landing aircraft controlling a tilt angle of a main rotor, based on a vertical posture control signal during low-speed flight, wherein, when an aircraft steering signal including a vertical posture control signal for changing the pitch posture angle of the vertical take-off/landing aircraft by a first pitch posture angle is obtained, a flight controller determines a tilt angle of the main rotor with reference to the first pitch posture angle and generates a tilt angle control signal for the main rotor based on the determined tilt angle.

  • Publication number: 20230026233
    Abstract: Provided is a system for controlling an RPM of a propeller and a rotor of a flight vehicle having multiple power units including: a collective pitch angle command generating unit generating a collective pitch angle command upon receiving a thrust control command from a pilot or an automatic controller; a disturbance factor compensating unit for generating an RPM compensation electronic speed control (ESC) command for compensating for an RPM error, and an electronic speed adjustment command generating unit generating a final ESC command upon receiving a collective command input or derived in the process of generating the collective pitch angle command by the collective pitch angle command generating unit and the RPM compensation ESC command generated by the disturbance factor compensating unit. RPMs of motors of a flight vehicle having a plurality of propellers and rotors may be maintained to be the same.

  • Patent number: 11361396
    Abstract: Disclosed embodiments provide systems and methods related to monitoring logistics. A method for monitoring logistics comprises capturing attendance data and timekeeping data for a first plurality of workers from a first management system, data identifying work performed by a second plurality of workers, the data comprising a location of performed work, an associated scan event, or clock-in information associated with each of a second plurality of workers, from a second management system, and work data related to a third plurality of workers from a third management system. The method further comprises consolidating the captured data on workers having corresponding data in one of the captured sets of data, receiving a request from a user device, for a visualization including analysis of the consolidated data, and providing a visualization to the user device, wherein the visualization is generated by analyzing the consolidated data.
