  • Patent number: 12275487
    Abstract: A moving body includes: a vehicle which includes a front wheel and rear wheels and which a passenger gets on; an unmanned carrier vehicle which is arranged at the back side of the vehicle, and includes a wheel and a driving unit which drives the wheel; and a coupler which couples the vehicle and the unmanned carrier vehicle. The coupler includes a biasing mechanism which biases a rear part of the vehicle toward an upper side of the vehicle, the biasing mechanism includes a first elastic member; when the passenger is on the vehicle, the first elastic member is deformed by the weight of the passenger to place the rear wheels in contact with a road surface, and when the passenger is not on the vehicle, the rear wheels are separated from the road surface by the elastic force of the first elastic member.

  • Patent number: 12214118
    Abstract: The present invention provides a method for producing condensation aerosols for the treatment of disease and/or chronic, intermittent or acute conditions. These condensation aerosols are produced from drugs including temperature sensitive drugs and small molecule drugs that are coated onto a foil substrate which is heated via electrical resistance heating at precisely controlled temperature profiles with controllable ramp-up and heating rates to vaporize the coated drug which subsequently condenses to form aerosol particles. These condensation aerosols have little or no degradation products. Kits comprising a drug and a device for producing a condensation aerosol are also provided. Also disclosed, are methods for using these aerosols and kits and methods of making the aerosols.
