  • Publication number: 20250036147
    Abstract: In a method of transporting cargo suspended by multiple UAVs, each of the multiple UAVs flies such that a relative positional relationship of each of the multiple UAVs to the cargo is maintained. This method of transporting cargo is achieved by one or both of a ground position control mode in which flight of each of the multiple UAVs is controlled to follow a change in a position of the cargo relative to the ground, and an interval control mode in which the flight of each of the multiple UAVs is controlled so as to maintain an interval of each of the multiple UAVs to the cargo.

  • Publication number: 20040002149
    Abstract: The present invention provides recombinant gene vectors and nucleic acid constructs which are capable of decreasing, reducing or suppressing the transcription/translation of LIP (transcription inhibitor protein), and in some examples, without affecting the transcription/translation of LAP (transcription activator). Such vectors and constructs are used in methods for increasing the ratio of LAP to LIP activity in a cell and for treating and/or ameliorating the symptoms of a disease or condition associated with the ratio of LAP to LIP. The present invention also provides methods for screening for agents that are capable of modifying the ratio of LAP to LIP activity in a cell or individual.
